Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia, and Target A1 is a polymetallic, silver-copper-z Inc. prospect located 28km to the east of the historic Kalengwa copper-silver mine which is currently under redevelopment. Highlights: Planned drilling programme of approximately 1,000m of Reverse Circulation drilling. Drilling to test: further lateral extensions of the known mineralisation, particularly around the high-grade silver and copper mineralisation in the north. the continuity of mineralisation between wider-spaced drill lines, by obtaining additional mineralisation intersections. the depth extension of the known mineralisation. Phase 2 drilling of this target in mid-2025 returned drill intersections including (downhole widths, true widths unknown): 58m at 49 g/t Ag, 0.26% Cu and 0.16% Zn (72 g/t Ag equivalent or 0.94% copper equivalent) from 8m downhole (hole 25TMNAC-038). Including: 20m at 86 g/t Ag, 0.,44% Cu and 0.24% Zn from 46m downhole. Drilling again before the rains, rather than waiting until the start of the next dry season in March-April next year, shows resolve to aggressively advance this Project and add shareholder value. "Target A1 now has a surface footprint of approximately 450m by 400m, with mineralisation intersected to a vertical depth of up to 84m. However, the mineralisation remains open to the north/northwest, south/southeast and at depth. This drill programme will test the potential continuation of mineralisation along strike and at depth, as well as providing additional infill drilling. This work is aimed at bringing closer to goal of producing a maiden mineral resource in the next 12 months. Drilling Programme A programme of approximately 1,000 m of Reverse Circulation ("RC") drilling is planned as a series of east-west drill lines spaced approximately 100m apart (north-south). Holes will be collared approximately 50 to 100m apart along the east-west lines and drilled to a nominal depth of approximately 100m. De De De De Deceal holes (approximately 150m) will also be undertaken in key areas to further understand the potential continuation of mineralisation at depth. The drill programme at Target A1 is designed to test: further lateral extensionsof the known mineralisation, particularly across the high-grade silver and Copper mineralisation previously intersected in drillhole 25TMNAC- 038; the continuity of mineralisation between wide-spaced drill lines, By obtaining additional mineralisation intersections; the depth extension of the known Mineral Resource Estimate, if future drilling results warrant such an approach. The drill programme is being conducted by Ox Drilling which also completed the Phase 1 and Phase 2 drill programmes. The drill programme is expected to commence in early November, will take approximately 2 weeks to complete and is planned to be finished prior to the on-set of the heavy rains in the area which will inhibit further on-the-ground exploration until March-April 2026. Samples will be initially analysed on site using a portable X-Ray Fluorescence ("pXRF") analyser for copper and zinc. Phase 1 drilling (1,486m) in 2024 targeted the copper-in-soil anomaly and returned broad but generally low-grade copper mineralisation as reported in the news release dated 28 October 2024 (e.g. 57m at 0.20% Cu from 14m downhole, hole 24TMNAC-004). Higher grade copper mineralisation was also intersected within these broader zones (e.g. 6m at 0.58% Cu within 35m at 0.21% Cu within 35m at 22m downhole, from 22m downhole, hole 24m downhole, hole 24 TMNAC-024).

Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia. Target A1 is a polymetallic, silver-copper-zinc prospect located 28km to the east of the historic Kalengwa copper-silver mine which is currently under redevelopment. Highlights: Near surface (from 2m) mineralisation identified up to a depth of 84m with a surface footprint of approximately 450m by 400m. 73m at 32 g/t Ag, 0.16% Cu and 0.24% Zn (49 g/t Ag equivalent or 0.64% copper equivalent) from 11m downhole (hole 25TMNAC-025). Including: 21m at 66 g/t Ag, 0.,21% Cu and 0.30% Zn from 50m downhole. Elevated values of additional critical metals, including antinomy (up to 0.21%) and gallium (up to 40 g/t), as well as bismuth (up to 991 g/t). Multiple targets defined based on regional geochemical and geophysical targets still to be drill tested located within 12km of Target A1. Located only 28km east of the Kalengwa copper-silver Mine (approx. 4Mt @ 5.2% Cu, 40 g/t Ag) and with a similar geological setting. Located in the Iron-Oxide-Co Copper-Gold ("IOCG") region of northwestern Zambia. Highly prospective for not only IOCG but also sedimentary copper and polymetallic occurrences. Target A1 Target A1 is a large copper-in-soil anomaly (3.1km by 1.7km) with copper values up to 302ppm (per Portable X-Ray Fluorescence, "pXRF") associated with a 1.7km by 0.5km zinc- and coincidental 1.3km silver-in-soil anomaly. Phase 1 drilling (1,486m) in 2024 targeted the copper-in-soil anomalies and returned broad but generally low-grade copper mineralisation as reported in the news release dated 28 October 2024 (e.g. 57m at 0.20% Cu from 14m downhole, hole 24TMNAC-004). Higher grade copper mineralisation was also intersected within these broader zones (e.g. 6m at 0.58% Cu within 35m at 0.21% Cu, from 22m downhole, hole 24 TMNAC-024). Drilling over the silver- and zinc-in-soil anomalies (drill line: 8506925N) to the east identified wide and thick, near surface silver mineralisation associated with low-grade copper and/or zinc mineralisation. The Phase 2 drill programme (1,116m) targeted the silver and zinc-in soil anomaly. The silver mineralisation has now been confirmed to extend approximately 450m northwest-southeast and by 400m northeast-southwest and to a depth from near surface to 84m and remains open both to the north/northwest, south/southeast and at depth. Historically, gold is associated with other deposits and occurrences with the region, and as such gold analysis is also being undertaken on selected mineralised intersections to ascertain whether gold mineralisation is associated with any of the mineralisation styles interested so far. The company is also in discussions with external, independent consultants to determine whether or not there is currently enough drilling data to support the reporting of an Exploration Target (following the guidelines of The JORC Code) so as to provide an estimated range of in-situ tonnes and grade. Next steps would include additional drilling with aims to test: Further lateral extensions of the known mineralisation, particularly around the high-grade silver and copper mineralisation, and the continuity of the known mineralisation between wider-spaced drill lines, by obtaining additional mineralisation interceptsaced drill lines, and extensions at depth.공시 • Sep 24Tertiary Minerals plc Announces Drilling Results for Further Three Holes from the Phase 2 Follow-Up Drill Programme At Target A1 At Its Mushima North Project in ZambiaTertiary Minerals plc announced drilling results for a further three holes from the Phase 2 follow-up drill programme at Target A1 at its Mushima North Project in Zambia. The analytical results from the new drillholes support the previously reported northern continuation of the thick near surface mineralisation defined by only one drill hole until now, extends over a width of approximately 300m. Silver mineralisation has now been intersected in drilling over a 350m by 300m area, and remains open to the north, south and at depth. Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia. Target A1 is a polymetallic, silver-copper-zinc prospect located 28km to the east of the historic Kalengwa copper-silver mine which is currently under redevelopment. Including: 15m at 63g/t Ag, 0.13% Cu and 0.56% Zn from 33m downhole. And: 16m at 1.59% Zn from 56m downhole. Mineralisation, including higher grade zones, remains open to the north, South and at depth. Results include the highest grades of zinc (3.35%) and antimony (0.21%) intersected to date from certified laboratory analytical results on the Project. Additional drill hole results expected in the coming weeks testing both northern and southern continuation of mineralisation. Initial mineralogical/metallurgical work now underway. Phase 2 Drill Programme As previously reported, the Phase 2 drill programme consisted of 1,116m of combined Air Core ("AC") and Reverse Circulation ("RC") drilling along a series of east-west drill lines spaced between 100m and 250m apart, north-south. Holes were collared approximately 100m apart along the east-west lines and drilled to the maximum depth possible at the time based on the drill rig capabilities and geological ground conditions (the bit refusal depth). The deepest drill hole in this programme was 99m and the average hole depth 70m. Combined Phase 1 and 2 drilling covers a surface footprint of approximately 1,680m by 550m. The Project's western boundary lies 20km to the east of the Kalengwa copper-silver Mine in northwest Zambia, one of the highest-grade copper deposits ever to be mined in Zambia (approximately 4 million tonnes at 5.2% copper and 40-80 g/t silver). In the 1970s, high-grade ore, reportedly averaging approximately 11% copper, was trucked for direct smelting at other mines in the Copperbelt. The Kalengwa mine is currently under redevelopment and is expected to produce 15,000 tonnes of copper annually. Several prospective targets have been defined thus far within the Project based on reviews of historic geochemical and geophysical survey data against the current exploration model developed by Tertiary (Targets A1, A2, B1, B2, B3 and C1). At the end of the summer 2024, Tertiary completed an initial (Phase 1) 25 AC drill hole programme (1,274m) to test parts of geochemical (copper-in-soil) anomalies at Targets A1 and C1. This limited and shallow drilling indicated wide downhole intervals of largely coincised by the current exploration model.공시 • Aug 13Tertiary Minerals plc Announces Completion of Phase 2 Drill Programme at Target A1, Mushima NorthTertiary Minerals plc announced the completion of the follow-up drill programme at Target A1 at its Mushima North Project and preliminary results from portable X-Ray Fluorescence analysis of drill samples. Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia. Target A1 is a polymetallic, silver-copper-zinc prospect. Phase 2 drilling is now complete, with 1,116m drilled over 16 holes. Extension of known mineralisation. Additional s ilver, zinc and copper mineralisation identified, extending the known mineralisation approximately 350m to the north and over a width of approximately 300m. Mineralisation remains open to the north and at depth. Results indicate the continuation of mineralisation to the north from the previous drilling for at least 350m, over broad intervals and with a continued width of approximately 300m. Higher copper values than previous results, such as 58m at 0.27% copper from 7m downhole, including 8m at 0.79% copper are particularly encouraging. Silver results from the pXRF analyser, while only indicative, do suggest the continuation of the silver mineralisation identified in the previous drill programme to the north. The preliminary results from the Company's internal analysis using a pXRF analyser indicate the continuation of mineralisation for at least 350m to the north of the previously reported drilling with significant silver, zinc and copper values. Mineralisation has also been intersected deeper than previously, to a vertical depth of approximately 82m on drill line 8506925N. Drill holes to the south (lines 8506650N, 8506360N and 8505650N) returned anomalous values of zinc and copper, but below the Company's reporting cut-off grades of 0.2% and 0.1%, respectively. However, the potential extent of silver mineralisation in this direction is unknown at this stage as the pXRF results for silver are not sufficiently reliable to indicate average grades over known mineralised extents. Certified, independent laboratory analysis is currently underway to confirm copper and zinc values and to ascertain silver values along with other potential, important accessory metals including bismuth, antimony and gallium. The agreement is non-binding to any further agreement and there are no commercial restrictions for Tertiary, nor does FQM have a right of first refusal over the Project. At the end of the summer 2024, Tertiary completed an initial (Phase 1) 25 AC drill programme (1,274m) to test parts of geochemical (copper-in-soil) anomalies at Targets A1 and C1. This limited and shallow drilling indicated wide downhole intervals of largely coincidental copper, zinc and silver mineralisation at Target A1. Numerous other geochemical and/or geophysical targets (A2, B2, B3, C2) are yet to be drill tested. Drilling Programme A programme of 1,116m combined Air Core ("AC") and Reverse Circulation ("RC") has now been completed, with a series of east-west drill lines spaced approximately 250m apart (north-south). Holes were collared approximately 100m apart along the east-west lines and drilled to bit refusal depth (average hole depth 70m).공시 • Jul 21Tertiary Minerals plc Announces Commencement of Drilling at Target A1, Mushima North Project, ZambiaTertiary Minerals plc announced commencement of drilling at Target A1, a polymetallic (silver-copper-zinc) prospect.

Highlights: Targeting sedimentary copper within the Lower Roan Subgroup, south of the Central African Copperbelt, within an underexplored region. Acquisition of regional and local exploration datasets, including regional soil sampling by First Quantum Minerals and historic drilling of key copper-in-soil targets. Significant fold structure identified with several discrete copper-in-soil anomalies along fold limbs (approximately 18km strike length). The Jacks Project is located in an underexplored but highly prospective region to the southeast of the world-class Central African Copperbelt. Acquisition of historic regional and local datasets, including drilling, has enabled the project to be fast-tracked and initially de-risked. Geological map of the Jacks Project showing the locations of the priority targets along the large-scale Central African Copperbelt. The Project is held through Group company Tertiary Minerals (Zambia) Limited (which in turn is 96% owned by Tertiary Minerals plc) and local partner, Mwashia Resources Limited. The area was subject to further exploration in the 1990s by Caledonia Mining Corporation ("CMC") which conducted aeromagnetic surveys and the geochemical sampling (1000m by 100m grid) which identified the copper-in-soil anomaly commented upon above. Following the delineation of the prospective areas, CMC entered into a joint venture earn-in agreement with Cyprus AMAX Minerals ("Cy Cyprus"), a major US-based mineral exploration and mining company. The 1997 exploration programme included infill geochemical sampling, a ground-based magnetic survey, Induced Polarisation survey and a 19-hole Reverse Circulation ("RC") percussion drill programme (2,170m). A further programme of six diamond drill holes ("DD") totaling 1,378m was completed in 1998 to test the along strike and down dip extensions to the previously intersected mineralisation as well some of the soil anomalies. The historic drilling results suggest the presence of two separate zones of copper mineralisation within the fold hinge area from near surface and with significant depth potential. Shallow intersects include: 0.76% copper over 12m from 18m downhole (KJ13). 0.35% copper over 10m from 67.5m downhole (KJD5). 22JKDD04 was another step-out hole, drilled approximately 160m east of 22JKDD01 and 170m south of 22JKDD03. A broad mineralised zone was intersected: 0.8% copper over 14.0m from 7m downhole, including two higher grade intersections: o 1.7% copper over 2.0m grading from 27m downhole, and o 1.0% copper over 5.0m from 35.0m downhole. Summary of drill assay results from the initial Tertiary drilling programme (2022) at the fold hinge (Jacks Project). Note to Table 2: Calculated intersections (down hole, true width unknown) are weighted averages using a cut-off grade of 0.2% copper. Project Summary The Jacks Project is located In an underexploring but highly prospective region to the Southeast of the world-class Central Africa Copperbelt. Acquisition of historic Regional and local datasets, including drill, has enabled the project to been fast-tracked and initially De-risked. Geological map of the Jacks Project show the locations of the priority target along the large-scale fold of the large-scale fold of prospective Lower Roan Subgroup geology. Historic drilling, as well as recent drilling undertaken by Tertiary, confirms the potential of the Project to host both shallow, lower-grade and deeper, higher-grade copper mineralisation. Limited drilling by Tertiary has intersected copper mineralisation between approximately 25m and 100m vertical depth from surface.

KoBold has the right to earn into the project by drilling two drill holes for a minimum of 2,000m. KoBold is targeting the potential continuations of mineralisation being mined at the world-class Musoshi, Lubambe and Konkola Mines, which had a pre-mining combined endowment of over 775Mt grading 2-3% copper. KoBold's Mingomba copper project is located approximately 5km to the northeast of the Project. Hole KWDD001 Drilling of hole KWDD001 has now been concluded after continued technical difficulties and limited advancement of the hole since the last update (20 February 2025) and having reached a down-hole depth of 2,711.1m. While the hole did not reach the targeted horizon (Ore Shale, Copperbelt Orebody Member), the geological data collected as part of the drilling has been instrumental in better understanding the previously unknown, geological architecture of the basin and has been used to update KoBold's proprietary geological models. As such, the hole has significant geological value and data generated from this hole will continue to be processed and analysed to inform future drilling at Konkola West. Two zones of low-grade copper sulphide mineralisation were intersected in this hole. The drill core from this entire hole is being analysed at an independent laboratory and any significant results will be released in due course. In addition, a wireline downhole geophysical survey has been completed collecting magnetic, induced polarisation, resistivity and gamma-ray data as well as mapping fracture density. KWDD001 is believed to be the deepest mineral exploration drill hole to ever be drilled in the Zambian Copperbelt and marks a significant milestone within the industry. Hole KWDD002 Despite stopping short of the target horizon in hole KWDD001, the results were sufficiently encouraging for KoBold to drill a second hole. Drilling of this hole (KWDD002) started on 26 March 2025. The location, orientation and expected length is based on KoBold's updated model for the basin, based on their extensive regional dataset and understanding, with data from KWDD001 being crucial to this. The expected hole depth is planned to approximately 2,000m. Konkola West Drill Programme Konkola West (Licence 27067-HQ-LEL) is located approximately 5 km to the SW of KoBold's Mingomb a deposit, which forms part of the Lubambe-Mingomba-Konkola copper deposits of the Zambian Copperbelt. The aim of the drill programme is to test the potentialcontinuations of mineralisation being mined and the World-Class Musoshi, Lubambe, and Konkola Mines (combined pre-mining endowment of over 775 millions grading 2-3% Copper). KoBold's MingOMa project, is reported by KoBold to be one of the larger undeveloped copper deposits in the world. KoBold is using its propriety AI-driven models of the regional geology to support its mineral exploration targeting. Earn-In Agreements The Earn-In Agreement is between Tertiary Minerals (Zambia) Limited, its local partner, Mwashia Resources Limited, and KoBold Metals. Under the initial Earn-in Agreement, KoBold is required to drill two holes and a minimum 2,000m of drilling within 14 months of signing the Earn-in Agreement. This period has now been extended by 4 months to allow the drill the second hole, which is expected to be approximately 2000m. In addition, a provision of the Earn-In Agreement has been made to ensure that KoBold's newly granted adjacent Large Exploration Licence, 38615-HQ-LEL, will also be granted adjacent Large Exploration Licence.공시 • Mar 17Tertiary Minerals plc Announces Additional Assay Results from Drilling At the Mushima North ProjectTertiary Minerals plc announced additional assay results from drilling at the Mushima North Project further to its announcement of 20 January 2025. The results identify a further wide drill intercept of silver mineralisation associated with previously reported copper-zinc mineralisation. Highlights: Results now available from samples from part of hole 24TMNAC006P (20-56m), located 50m west of previously reported silver mineralised hole 24TMNAC004. 30 g/t silver, 0.16% copper and 0.34% zinc over 36m, from 20m down hole. Including: 54 g/t silver,0.21% copper and 0.33% zinc over 12m, from 31m downhole. Including: 1m grading 176 g/t, 0.38% Cu and 0.29% Zn silver from 32m. 34 g/t silver and 0.12% copper and 0.3% zinc over 4m, from 52m. Previously reported analyses for these holes were for copper and zinc and were based on field portable X-Ray Fluorescence (pXRF) analysis which is not a suitable method for silver analysis. Silver mineralisation is now intersected in two holes 50 m apart. However, laboratory assay results for silver (and confirmation for copper and zinc) are still awaited for parts of both holes in addition to the entire lengths of a further five holes along the same drill line. The drill line targets part of a silver in-soil geochemical anomaly that is approximately 1.4km long and up to 300m wide and coincident with a broader zinc and copper anomaly. Previously released pXRF results for copper and zinc indicates many of the holes ended in mineralisation. The Mushima North Copper Project (Licence 27068-HQ-LEL) is held through Group company Copernicus Minerals Limited ("Copernicus") which is 90% owned by Tertiary Minerals (Zambia) Limited and 10% by local partner, Mwashia Resources Limited. The Project lies 20km to the east of the Kalengwa copper mine in northwest Zambia, one of the highest-grade copper deposits ever to be mined in Zambia. In the 1970s, high-grade ore, in excess of 26% copper, was trucked for direct smelting at other mines in the Copperbelt. The Kalengwa mine is now being reopened and is expected to produce 15,000 tonnes of copper annually. The Project is under a technical cooperation agreement with First Quantum Minerals Limited ("FQM"), which allows Tertiary to benefit from FQM's historic exploration data in the area, as well as FQM's geological team's extensive experience and understanding of the area's geology.공시 • Feb 27Tertiary Minerals plc Provides Update on Brunton Pass Project – Drilling ResultsFurther to its announcement dated 16 December 2024, the Tertiary Minerals plc announced the results of drilling from the Phase 1 Drill Programme at its 100% owned Brunton Pass Copper-Gold Project in Nevada, USA. Highlights: Four reverse circulation percussion drill holes completed for a total of 890m in first pass drill programme. All four holes intersected thick intervals containing anomalous copper values associated with fresh and oxidised pyrite and trace chalcopyrite. Cumulative drill thicknesses up to 210m grading 170ppm copper (Hole 24TBPRC002) with values up to 0.19% copper over 1.53m. Anomalous copper values extend to at least 212m vertical depth, 630m east-west and 560m north-south. Surface mercury and arsenic indicator anomalies persist at depth. Deeper diamond drilling is justified to test the core of the target Induced Polarisation ("IP") geophysical anomaly. Petrographic and additional geochemical analysis planned to assist future drill targeting. A map and two cross sections can be found at the end of this release illustrating the exploration results to date. The Brunton Pass Project is located in central Nevada, USA, 25km northeast of the high-sulphidation epithermal Paradise Peak gold deposit that produced over 1.6 million ounces of gold, over 44 million ounces of silver and at least 457 tons of mercury. The Project was acquired in 2021 after sampling of prospector small-scale surface workings revealed high copper values. Mineralisation at Brunton Pass occurs within a series of limestones, siltstones and sandstones of the Triassic-age Luning Formation that have been widely converted by thermal metamorphism and metasomatism to hornfels and calc-silicate skarn units. These altered rocks form a 1.8km x 0.75km, uplifted "window" (horst block) in fault contact within younger Tertiary-age volcanic rocks. Evidence for an underlying body intrusive is found in surface outcrops of granite/granodiorite and at least two phases of diorite intrusion. Soil sampling has delineated several copper-in-soil anomalies with individual grades of up to 953ppm copper. The largest of these anomalies in the southwest quadrant of the property has dimensions of 340m x 310m and they are mainly coincident with areas where rock grab samples contain percent-level copper values in small prospecting pits. In 2022, the Company excavated two trenches in the area, T7 and T8, which encountered low-level copper mineralisation at surface including 27.4m grading 0.1% copper. Further details can be found in the news release dated 16 December 2024. Drill holes 24TBPRC001 and 24TBPRC002were drilled to test for mineralisation below the main copper soil anomaly and trenches T7 and T8. Hole 24TBPRC001intersected three intervals of anomalous copper with a cumulative downhole thickness of 123.45m and a weighted average grade of 149ppm copper. Mineralisation is mainly oxidised, but in the lower part of the hole the iron-sulphide mineral pyrite occurs with trace chalcopyrite. Sporadic quartz, gypsum and quartz-calcite veins were also intersected. The main host to mineralisation in hole 24TBPRC001 is a biotite-rich rock which at surface has been mapped as a diorite intrusive but which may also be a metamorphosed sedimentary rock. Further mineralogical work is required to make a definitive determination. Hole 24TBPRC002was drilled approximately 265m east of, and directed towards, hole 24TBPRC001. It intersected a sequence of sandstones and limestones, mainly altered to hornfels and calc-silicate rock. It intersected two main zones with anomalous copper values having a cumulative downhole thickness of 210m and a weighted average grade of 170ppm copper. A 1.53m interval grading 0.19% copper was intersected from 59.71m downhole and the hole ended in mineralisation at 252.98m depth. Drill Holes 24TBPRC003 and 24TBPRC004were drilled some 630m apart and were designed to test a north-south striking IP geophysical (chargeability) anomaly that stretches over several hundred metres and which is coincident with a broad zone of mercury and arsenic anomalies in soils and trenches. Hole 24TBPRC003was anomalous in mercury throughout its 137m length averaging 9.25ppm, which is approximately 450 times background levels of 0.02ppm mercury. The rocks were variably altered with hematite and manganese oxides within a mixed sequence of hornfels, calc-silicate rock and limestone. The hole was also targeting altered rocks adjacent to a granodiorite dyke which contained high gold values but the hole stopped short of target. Hole 24TBPRC004, drilled some 560m south of hole 24TBPRC003, also intersected anomalous mercury, with anomalous arsenic and copper and a cumulative downhole intersection of 132.69m grading 130ppm copper including 103.64m grading 142ppm copper, 488ppm arsenic and 3.5ppm mercury. Disseminated pyrite was present through most of the drill hole. Drilling has confirmed that the copper anomalies seen in surface soil samples and trench samples persist at depth to at least the lowest level tested in the current drilling (212m below surface in hole 24TBPRC002) and in an area 560m east-west and 560m north-south. This is a large body of rock containing anomalous copper values and, on the eastern side, anomalous indicator metals, mercury and arsenic. The Company's working thesis is that this large area may represent the halo to a buried porphyry copper deposit and that deeper drilling is justified.공시 • Feb 25Tertiary Minerals plc Announces the Appointment of Richard Belcher as the Managing Director, Effective 7 March 2025Tertiary Minerals plc announced the appointment of Dr. Richard Belcher as the new Managing Director of the Company.

Details of the Earn-In Agreement were outlined in the Company's news release dated 19 December 2023. Drilling of hole KWDD001 has advanced past 2,600m down-hole depth and is now drilling ahead in the Kitwe Formation which forms the upper part of the Lower Roan Subgroup and which, at its base, is host to the Ore Shale (Copperbelt Orebody Member) of the Zambian Copperbelt. The drill hole is currently in the Shale with Grit unit of the Kitwe Formation, the base of which is typically between 25-225m above the Ore Shale in the Konkola area1. If conditions and equipment allow, the planned completion depth for KWDD001 is 3,000m. Drilling has taken substantially longer than expected and KWDD001 has drilled deeper than originally planned. This is due to folding, possibly along an extension of the major Fitwaola fault system. Drilling also becomes progressively slower with depth due to the incremental time required to recover drill core from the drill face. Second Drill Hole KoBold has advised the Company that it plans to start drilling a second deep hole at Konkola West shortly after the completion of the first hole. A number of possible locations have been selected where the Lower Roan is now projected to be closer to the surface with a final location decision contingent on further geological interpretation of hole KWDD001. Further Agreements Under the Earn-in Agreement, KoBold is required to complete two holes and a minimum 2,000m of drilling within 14 months of signing the Earn-in Agreement. In the circumstances, Tertiary Minerals (Zambia) Limited and its local partner, Mwashia Resources Limited, have agreed with KoBold to extend this 14-month period by four months to allow time to start and progress drilling of the second hole. The parties have also signed a second agreement to give effect to a provision of the Earn-In Agreement to ensure that KoBold's newly granted adjacent Large Exploration Licence, 38615-HQ-LEL, will be also be held under the terms of the Earn-in Agreement for the benefit of all the parties.공시 • Jan 29Tertiary Minerals plc, Annual General Meeting, Mar 06, 2025Tertiary Minerals plc, Annual General Meeting, Mar 06, 2025.공시 • Jan 21Tertiary Minerals plc Announces New Silver Discovery at Mushima NorthFurther to its announcement of 28 October 2024, and as a result of laboratory check analysis of drill samples, Tertiary Minerals plc announced the discovery of economically significant silver and cobalt mineralisation associated with previously announced copper-zinc mineralisation at its Mushima North Project in Zambia. Highlights: Four drill holes submitted for laboratory multi-element check analysis, three drill holes checked from Target A1 including: Hole 24TMN004 (Drill Line 1) - 59mgrading 25 grammes/tonne ("g/t") silver, 0.2% copper and 0.16% zinc from 10m to end of hole at 72m including: 26m grading 36g/t silver,0.20% copper and 0.20% zinc from 45-72m. Hole ended in mineralisation grading 49g/t silver, 0.24% copper and 0.15% zinc. Previously reported copper and zinc values confirmed by laboratory check analysis. Hole 24TMN024 (Drill Line 1): Significant cobalt associated with previously reported higher grade copper interval: 6m grading 0.08% cobalt, 0.58% copper from 47-53m. Entire hole, where check analyses are available, is anomalous in copper and cobalt: 74m grading 0.14% copper, 0.03% cobaltand 3g/t silver from 20m to 96m at end of hole. Hole also anomalous in nickel with best intersection of 4m grading 0.12% nickel, 0.09% cobalt, 0.18% copper and 5g/t silver from 42-46m. · Hole 24TMN016from Target C1 shows narrow intervals of low-grade gold mineralisation. · Silver-in-soil geochemical anomaly associated with Hole 24TMN004 evident in check soil analytical data - 1.3km long and open ended to the northeast and southwest. Repeat silver analysis on 14 check samples using a stronger acid digest method returned silver values 12% higher than those now being reported. Check Analysis of Drill Samples - New Results: Results are now available for five drill holes that were selected for check analysis. This included four holes from Target A1 (Hole Numbers 24TMN004, 6P, 11 and 24) and Hole TM24TMN16 from Target C1 (see accompanying map and drill section). Drill hole 24TMN006P was only analysed for gold. Check analysis for copper and zinc confirmed the previously reported results except for one interval for zinc in Hole 24TMN011 which requires further investigation (see accompanying table). Significant silver values were found throughout Hole 24TMN004 in broad association with copper and zinc whilst significantly anomalous cobalt and nickel and silver was found in hole 24TMN024 with the highest cobalt grades accompanying the highest copper grades. Target A1 was first defined by pXRF analysis of soil which defined a large copper-in-soil anomaly which was subsequently confirmed by laboratory check analysis of samples taken along three sample lines within the anomaly (see accompanying map). A review of the silver values in these check soil analyses has now revealed a silver-in-soil anomaly within the copper-in-soil anomaly that extends northeast-southwest for at least 1.3km across all of the three check lines. This silver anomaly is open-ended in both of these directions. The accompanying map and drill section illustrates that, of the drill holes selected for check analysis, only hole 24TMN004 was drilled within the silver-in-soil anomaly. However, The company anticipates that additional laboratory analysis of other drill holes on Line 1 that fall within the silver-in-soil anomaly may also reveal significant silver mineralisation. The map also illustrates that drill hole 24TMN024, whilst hitting a thick interval of lower grade silver, was likely drilled too far east, on the edge of the silver-in-soil anomaly and the current belief is that the two southerly drill lines (including Hole 24TMN011) were both drilled too far to the west to hit the main copper-zinc and silver targets. Check analysis of drill hole 24TMN016 at Target C1 area intersected two narrow intervals of anomalous gold in granite: 0.47g/t gold from 5-6m downhole and 0.25g/t gold from 22-23m and confirmed the previously reported narrow interval of copper mineralisation. As a further check on the silver values now being reported, fourteen samples were submitted for repeat analysis by a different laboratory method using a stronger acid digest for more complete dissolution of contained metals. The repeat analyses confirmed the silver discovery and returned 12% higher silver values on average.공시 • Dec 17Tertiary Minerals plc Successfully Completes its First Drilling Programme at the 100% Owned Brunton Pass Copper-Gold Project in Nevada, USATertiary Minerals plc announced that further to its announcement of 15 November 2024, the company announced that it has successfully completed its first drilling programme at the 100% owned Brunton Pass Copper-Gold Project in Nevada, USA. All four of the planned drill holes were completed and over 700 samples have been submitted to an independent laboratory, Paragon Geochemical in Reno, Nevada, for analysis for base and precious metals. Results are expected in January 2025 and will be reported as soon as possible thereafter.공시 • Nov 15Tertiary Minerals plc Commences at its 100% Owned Brunton Pass Copper-Gold Project in Nevada, USATertiary Minerals plc advised that drilling has commenced at its 100% owned Brunton Pass Copper-Gold Project in Nevada, USA. Detailed Information: The Brunton Pass Project is located in central Nevada 25km northeast of the high-sulphidation epithermal Paradise Peak gold deposit that produced over 1.6 million ounces of gold and over 44 million ounces of silver and at least 457 tons of mercury. The Project was acquired in 2021 after sampling of prospector small-scale surface workings revealed high copper values. Mineralisation at Brunton Pass is closely associated with hornfels, skarn and high-sulphidation-style epithermal alteration of a mixed sequence of Triassic aged carbonate and clastic sediments that form a 1.8km x 0.75km, uplifted "window" (horst block) in fault contact within younger Tertiary-age volcanic rocks. Evidence for an underlying body intrusive is found in surface outcrops of granite/granodiorite and at least two phases of diorite intrusion. Copper Target Soil sampling has delineated several copper-in-soil anomalies with individual grades of up to 953ppm copper. The largest of these anomalies in the southwest quadrant of the property has dimensions of 340m x 310m and they are mainly coincident with areas where rock grab samples contain percent-level copper values in small prospecting pits. In 2002, two trenches were completed for a combined length of 386m to further evaluate the main anomaly and wide intervals of low-grade copper observed in trenches T7 and T8: · 27.4m grading 1,010ppm copper (0.1% Cu) in T7, open to the east. 77.7m grading 473ppm copper in T8, also open to the east. These wide low-grade copper intervals are a possible halo to more significant mineralisation and suggest the possible presence of a deeper porphyry copper target. Two reverse circulation drill holes of 350-400m each are planned to test this target. Gold-Silver Target During soil sampling two large mercury and arsenic in soil anomalies were also defined in the eastern half of the property in a north trending zone with values up to 52 ppm mercury with the largest of these extending over an area approximately 500m x 500m. These anomalies are centred on a north trending zone of structural dislocation with a strike length of at least 1.2km. Two trenches (T1 and T11) tested the north and south ends of this mercury-arsenic soil anomaly and intersected substantial widths of hydrothermally altered rock with approximately 1,000 times background content of the gold indicator elements, arsenic and mercury: · 9.1m grading 1,930ppm arsenic and 102ppm mercury in T1. · 32m grading 1,622ppm arsenic and 110ppm mercury T11. The argillic alteration evident in T1 and T11 is similar to that seen at the Paradise Peak Gold Mine (smectite+quartz+/-opal). Trench T2, located between T1 and T11, intersected 2.65g/t gold over 2.7m. In early 2024, an IP Survey and Resistivity geophysical survey identified a coherent electrical chargeability anomaly, typical of sulphide mineralisation prospective for copper and/or gold, extending over 700m through all IP survey lines. The chargeability anomaly is spatially related to the previously identified copper-mercury-arsenic soil anomalies, the surface alteration zone in trench T11 and the gold-bearing zone in trench T2. Resistivity variations are conformable with surface geology and help map out subsurface geology. The chargeability anomaly and associated geochemical anomalies are a high priority drill target for epithermal gold and/or porphyry copper mineralisation and two reverse circulation drill holes are planned to test this target.공시 • Nov 04Tertiary Minerals plc Commences Drilling At the Mukai Copper Project in ZambiaTertiary Minerals plc advised that First Quantum Minerals Limited ("First Quantum") has commenced drilling at the Mukai Copper Project in Zambia following the receipt of all necessary consents. The Company has received approval from the Department of Forestry to conduct further mineral exploration, including drilling, in the Licence area (the "Licence"). Consent has also been granted by the leadership of local tribal group, the Musele Royal Establishment ("Musele Chiefdom"), to conduct mineral exploration on the Licence. Phase 1 drill programme, now underway, will comprise up to 6 diamond drill holes, with drilling depths ranging between 350 and 400m. The drill programme will test beneath the large soil anomaly defined by Tertiary in 2023 which is contiguous with First Quantum's Tirosa Copper Prospect on the adjoining mining licence. Under the Company's agreement with First Quantum, First Quantum must define a minimum resource of 80,000 tonnes of copper before it can earn an interest in the Licence. The Licence lies adjacent to First Quantum's Trident Project which comprises various mining licences encompassing the producing Sentinel Copper Mine and the recently developed Enterprise Nickel Mine. The Sentinel processing plant has a processing capacity of 55 million tonnes of copper ore per year. The Licence renewal has been approved for an additional three years and is awaiting transfer to Copernicus Minerals Limited ("Copernicus"). Further details are given in the Company's news release of 6 June 2024. The Company's exploration at Mukai in 2023 resulted in the identification of a substantial copper-in-soil anomaly on the Licence. This soil anomaly occurs along strike from copper mineralisation that has been identified in past drill programmes at First Quantum's Tirosa Prospect, on its adjoining Trident Project area, which encompasses the Sentinel Copper and Enterprise Nickel mines. The Sentinel Mine was developed with a total investment of over USD 2.1 billion and is expected to produce around 235,000 tonnes of copper metal this year. The Enterprise Nickel mine is newly opened and expects to produce around 20,000 tonnes of nickel in 2024. Both deposits are sediment-hosted and occur in sedimentary basins formed on and around the Kabompo Dome. A similarly located basin hosts the Tirosa Prospect and continues into the Licence. As announced on 7 August 2024, Copernicus and First Quantum have signed a Binding Letter of Agreement ("BLA") allowing First Quantum to evaluate and earn an interest in the Licences by completing a minimum exploration expenditure of USD 1,500,000 during a 24-month due diligence period and by defining a minimum resource of 80, million tonnes of contained copper. In late August 2024, a series of meetings were held at the Department of Forestry's Solwezi District Office and the Lusaka headquarters to outline the proposed work programmes resulting in the submission of a formal application which has now been approved. In order to gain a Letter of Consent from the Musele Chiefdom, the Company met with Senior Chief Musele in September 2024 and as such were the first company to meet the Senior Chief Musele since the installation ceremony in July 2024. The Company hosted a community event where a presentation was made to the Musele Chiefdom to introduce the Company, the proposed exploration operations and address any concerns. A Letter of Consent has now been received from the Musele Chiefdom and, upon notification, First Quantum initiated drill preparation with the intention of completing a Phase 1 diamond drill programme. Phase 1 of the drill programme will comprise up to 6 diamond drilling holes to depths ranging between 350m and 400m on two fence lines. Drilling is now underway and will continue for so long as weather conditions permit following the onset of the wet season in Zambia.공시 • Oct 16Tertiary Minerals plc Completes Inaugural Drill Programme At Its Mushima North Copper Project in ZambiaTertiary Minerals plc advise that the Company's inaugural drill programme at its Mushima North Copper Project in Zambia has now been completed. Summary: Drilling aimed to test the A1 and C1 coincident copper, zinc and arsenic soil anomalies defined by the Company's soil sampling programmes completed in 2023.

Mushima North Copper Project (Zambia): The Mushima North Copper Project (Licence 27068-HQ-LEL) is held through Group company Copernicus Minerals Limited (‘Copernicus’) which is 90% owned by Tertiary Minerals (Zambia) Limited. Copernicus is in the process of taking a transfer of the licence through its agreement with licence holder, Mwashia Resources Limited. The project lies 20km to the east of the Kalengwa copper mine which is now being reopened and is expected to produce 15,000 tonnes of copper annually. Kalengwa was one of the highest-grade copper deposits ever to be mined in Zambia. In the 1970s high-grade ore, in excess of 26% copper, was trucked for direct smelting at other mines in the Copperbelt. Kalengwa was discovered by drill testing a coincident copper-in-soil anomaly and gravity anomaly and has characteristics of the Iron-Oxide-Copper-Gold (‘IOCG’) class of deposits. In 2023, following a detailed targeting project, Tertiary carried out soil sampling over the A1, A2 and C1 targets, defining significant copper in soil anomalies. A contract has now been signed with Ox Drilling for up to 2,500m of aircore drilling which will primarily test the large A1 soil anomaly in a number of drill traverses. The A1 copper-in-soil anomaly covers an area of approximately 3km by 1.5km and is considered prospective for traditional Copperbelt style mineralisation. Drill access and preliminary drill pad preparation have been completed. Drilling is expected to start today and run for approximately 2-3 weeks. Samples will be analysed in the field using a hand-held portable x-ray fluorescence (‘pXRF’) spectrometer with follow-up laboratory based check analyses. A geophysical programme is also being planned to better define the gravity and magnetic anomalies defined by BHP at Target C1. BHP had planned two holes in 2011 to test these anomalies for IOCG style mineralisation but terminated all exploration in Zambia prior to drilling these holes. The Konkola West Project comprises Exploration Licence 27067-HQ-LEL which covers 71.9 sq. km. and is located 18km northwest of Chingola in the Central African Copperbelt. KoBold has the right to earn-in to the project and is funding exploration costs. Further details of the agreement with Mwashia and KoBold can be found in the Company's announcement dated 19 December 2023. The Konkola West Project is targeting deep down-dip and along-strike extensions of the contiguous Lubambe-Mingomba-Konkola copper deposits to the west of the Licence and which extend north into the Musoshi mining complex in the Democratic Republic of the Congo. Together these deposits comprise a 15km-long continuous zone of mineralisation that contained a pre-mining endowment of over 775 million tonnes grading 2-3% copper. Konkola West is located approximately 2,000m southwest of the Mingomba deposit which lies between the Konkola and Lubambe mines and which is currently being evaluated by KoBold. KoBold has reported Mingomba to be one of the largest undeveloped copper deposits in the world. KoBold is committed under the earn-in Agreement to drill at least two holes for a minimum of 2,000m of drilling. Drilling of the first hole, KWDD001, commenced in mid-April and is continuing. The drilling is slow due to the depth of drilling (now in excess of 2,000m) and the technical challenges in drilling at such depths in new, undrilled areas. KoBold remains committed to continuing the hole until it reaches its target horizon or the limits of the rig's capabilities. The Mukai Copper Project (Licence 27066-HQ-LEL) covers 55.4 sq. km. and is located 125km west of Solwezi in the north-western Province of Zambia. It is currently being transferred to Copernicus. The licence is directly adjacent to FQM's Trident Project, which includes the recently opened 35 million tonne Enterprise Nickel Mine and the 894 million tonne Sentinel (Kalumbila) Copper Mine, located 8km south and 18km southeast of the licence, respectively. FQM has invested USD 2.1 billion in the Sentinel Copper Mine where the plant has the capacity to treat 55 million tonnes of ore per annum. The Mukai Project is also located just to the west of Arc Minerals' project area on the opposite flank of the Kabompo Dome, where Anglo American can earn a 70% interest from Arc Minerals through expenditure of USD 88.5 million, including USD 14.5 in cash payments. Copernicus has signed a binding letter of agreement (‘BLA’) giving FQM the right to earn up to an 80% joint venture interest in the Mukai Project. Copernicus is carried at a 20% equity level all the way through to the start of mining. Full details of the BLA are given in the Company's announcement dated 7 August 2024. In 2023, Tertiary carried out a detailed soil sampling programme which resulted in the identification of a substantial copper-in-soil anomaly on the Licence as described in the Company's announcement dated 12 September 2023. FQM is ready to start drilling this dry season provided the necessary local consents can be obtained in time. A two-phase, 12-hole diamond drilling programme has been planned to test the copper-in-soil geochemical anomaly. The Jacks Exploration Licence 27069-HQ-LEL covers 141.4 sq. km. and is located 85km south of Luanshya in the Central African Copperbelt. It is currently being transferred to Copernicus. Copper mineralisation occurs within the southern limb of a large asymmetric synclinal fold structure. Historical drilling and four holes drilled by Tertiary suggests that copper occurs in two separate mineralised horizons which may be discrete mineralised zones but could, alternatively be one refolded horizon. In October 2022, Tertiary carried out a programme of soil sampling to follow up unresolved copper-in-soil anomalies defined during wide spaced soil sampling by previous operators including Cyprus-Amax and FQM, as well as to guide follow-up drilling on the Jacks main prospect. The results of analysis have delineated significant copper-in-soil anomalies on a number of separate sampling grids with peak values ranging from up to 525ppm copper, a result that compares favourably with soil anomalies in the vicinity of various ore zones at current and past producing mines on the Copperbelt. A programme of pitting is now underway. Approximately 25 pits will be excavated over key soil sample locations to allow for decisions on follow-up drilling. Pit samples will be analysed by pXRF. The programme will take approximately 7 days to complete. The Brunton Pass Project is located in central Nevada, 25km northeast of the high-sulphidation epithermal Paradise Peak gold deposit that produced over 1.6 million ounces of gold and over 44 million ounces of silver and at least 457 tons of mercury.공시 • Aug 29Tertiary Minerals plc has completed a Follow-on Equity Offering in the amount of AUD 0.88 million.Tertiary Minerals plc has completed a Follow-on Equity Offering in the amount of AUD 0.88 million.

The Mupala Copper Project is located adjacent to the Anglo American/Arc Minerals Joint Venture ("JV") Project, where Anglo American has a right to earn a 70% interest through expenditure of USD 88.5 million, and 12 km west of the Company's Mukai Project. Geologically located on the west side of the Kabompo Dome, in the prospective Domes Region of northwest Zambia, which is host to multiple producing copper and nickel mines, including First Quantum Mineral's Trident Project which adjoins the Company's Mukai Project; A total of 684 soil samples collected on a 300m by 300m offset grid with infill sample spacing of 150m by 150m in areas of anomalous copper-in-soil. Copper-in-soil anomaly approximately 1,800m long by 600m wide identified with a peak value of 422 ppm copper determined by portable X-ray fluorescence (pXRF) analysis. The anomaly is consistent with historical exploration data and extends to the licence boundary with the Anglo American/Arc Mineral JV. A sub-set of samples will be submitted for check laboratory based geochemical analysis. The Licence is underlain by rocks of the prospective Lower Roan Subgroup and lies directly adjacent to the Anglo American/Arc Minerals joint venture area where Anglo American has the right to earn a 70%interest through expenditure of USD 88. 5 million. Approximately 12 km to the east lies the Company's Mukai Copper Project and First Quantum Minerals' Trident Project which is host to the Enterprise Copper and Sentinel Nickel Mines. Existing geological maps indicate that the licence covers some 16 km strike length of the main copper mineralised horizon in Zambia (Lower Roan Subgroup). Historical exploration records, albeit incomplete, identified a number of copper-in-soil anomalies which provided an initial focus for the Company's exploration of the Licence area. First pass soil samples were taken on a 300m by 300 m offset grid over the entire Licence area with samples collected from a depth of approximately 30cm in the B-horizon of the soil profile and dry-sieved to -180 micron. A subsample of the minus soil fraction was then placed into a plastic sample cup and analysed in the field by a portable X-ray fluorescence instrument ("pXRF") to provide analytical results. A total of 452 first pass soil samples were collected. Analytical results were relayed from the field and infill sampling was conducted in the areas of anomalous copper- in areas of anomalous copper -in-soil and a total of 232 infill samples were collected. The main copper-on-soil anomaly is approximately 1,800m long and 600m wide with a peak value of 422ppm and is broadly coincident with a surface geochemical anomaly defined by Mwinilunga Mines in the 1960s. A sub-set of soil samples will now be submitted for conventional laboratory based geochemical analysis as a QA/QC check on field results. Further follow up work is planned to follow up the significance of the soil geochemical anomaly to include trenching and/or drilling.공시 • Jun 21Tertiary Minerals plc Announces Drilling Update, Konkola West Copper ProjectTertiary Minerals plc announced that the first hole at the Konkola West Copper Project, hole number KWDD001, was recently reported by KoBold Metals Company to be at a downhole depth of 1,341m and continuing in the hanging wall sequence above the target horizon. More recently, drilling progress has been a little slower than anticipated due to use of a new drill rig and variable ground conditions. Drilling will continue until the target horizon is reached. No further announcement will be made until this first hole is completed but planning for a second drill hole is already underway.공시 • May 22Tertiary Minerals plc Provides the Drilling Update for the Konkola West Copper Project in ZambiaTertiary Minerals plc provided the drilling update for the Konkola West Copper Project in Zambia. The first hole at the Konkola West Copper Project, hole number KWDD001, being drilled as part of an earn-in agreement with a subsidiary of KoBold Metals Company ("KoBold") and local partner Mwashia Resources Ltd, was recently reported by KoBold to be at a depth of 1,023m down-hole and continuing. The target of this drillhole is the ore-shale which hosts the copper mineralisation at the Konkola-Lubambe copper mines and the nearby Mingomba deposit. KoBold has reported that a number of expected key marker horizons have been intersected in the hole that are consistently seen in the stratigraphy above the ore-shale in these deposits. Given the known lateral variations in the thickness of individual stratigraphic units in this area it is not yet possible to predict with any certainty the depth at which the ore-shale might be encountered, though the Company estimates that drilling of KWDD001 will continue until mid-June 2024 with assay results to follow after that. However, drilling could take longer, or be completed sooner, depending on the thickness of the stratigraphic units yet to be drilled, as well as drilling conditions.공시 • May 10Tertiary Minerals plc Announces the Approval of the Environmental Project Brief for Its Mupala Copper ProjectTertiary Minerals plc announced the approval of the Environmental Project Brief ("EPB") for its Mupala Copper Project (32139-HQ-LEL or the "Licence") which now clears the way for the start of mineral exploration activities at Mupala. The Mupala Copper Project is located 12 km west of the Company's Mukai Project and adjacent to the Anglo American/Arc Minerals joint venture project where Anglo American has a right to earn a 70% interest through expenditure of $88.5 million. Located in the prospective Domes Region of northwest Zambia on the west side of the Kabompo Dome which is host to multiple producing copper and nickel mines including First Quantum Mineral's Sentinel mining complex which adjoins the Company's Mukai Project. Letter of Consent received from Sailunga Chiefdom during tribal engagement conducted in February 2024 and EPB approval now received from the Zambia Environmental Management Agency. Recently acquired historical data has identified multiple copper-in-soil anomalies within the Licence. Work programmes expected to commence next month and will include soil sampling across the Licence to verify the identified soil anomalies and assist with surface regolith mapping.공시 • May 03Tertiary Minerals plc Announces Exploration Update - Brunton Pass Project, Nevada, USATertiary Minerals plc announced positive results from a recently completed geophysical survey at its Brunton Pass Copper-Gold Project in Nevada, USA. Highlights: Induced Polarisation ("IP") and Resistivity geophysical survey completed over 7.2 line-km on four lines over total target strike length of 700m; Coherent electrical chargeability anomaly, typical of sulphide mineralisation prospective for copper and/or gold, extends through all IP survey lines; Chargeability anomaly is spatially related to previously identified: copper-mercury-arsenic soil anomalies; a surface alteration zone in trench T11 where pathfinder elements arsenic and mercury are at 1,000 times background; and a gold-bearing zone in trench T2 where sampling yielded values up to 2.7g/t gold.

Key Points: Areas A1 & A2 are targets for traditional Copperbelt sediment-hosted mineralisation where known deposits in Zambia and the DRC range in size up to supergiant size (>25mt contained copper). 248 soil samples were initially collected on a 200m x 200m spaced grid at the A1 and A2 targets. A further 311 samples were taken as an infill of the A1 grid at 100m x100m spacing and at 50m spacing along three east-west lines. pXRF analytical results at target A1 have outlined a significant open-ended copper anomaly with soil samples above 80ppm covering an area of 3 km long by up to 1.5 km wide, peaking at 280ppm copper. A high-grade area within the A1 copper-in-soil anomaly with values above 200ppm and averaging 231ppm copper has dimensions of 400m x 150m. pXRF results at target A2 show very high copper values, up to 1,239ppm copper in organic-rich samples from the perimeter of a marsh (dambo). The copper in this hydromorphic anomaly is likely transported and may be linked to the source of the A1 copper-in-soil anomaly. A new copper prospect was discovered during field evaluation of a historic electromagnetic target to the west of target A1. Values up to 0.43% (4,300ppm) copper were returned from average pXRF analysis of surface rocks showing visible oxide copper mineralisation. The Mushima North Copper Project comprises Exploration Licence 27068-HQ-LEL. It covers 701 km2 and is located in Zambia's Northwest Province. Tertiary Minerals plc's 96% owned subsidiary, Tertiary Minerals (Zambia) Limited, is currently earning up to a 90% interest in the Project from local partner Mwashia Resources Limited. Mushima North is one of five projects in Zambia where Tertiary is exploring for copper and one of two projects which benefit from the Company's technical cooperation and data sharing agreement with leading copper producer First Quantum Minerals. The Project lies 20 km to the east of the Kalengwa copper mine (past production 4 million tons grading 5.2% Cu and 40 g/t Ag and pre-mining reserve of 600,000 tons grading 16% copper) believed to be one of the highest-grade copper deposits ever to be mined in Zambia. In the 1970s high grade ore in excess of 26% copper, making up approximately 20% of the orebody, was trucked for direct smelting at other mines in the Copperbelt. Kalengwa was discovered by drill testing a coincident copper-in-soil anomaly and gravity anomaly and has characteristics of the Iron-Oxide-Copper-Gold ("IOCG") class of deposits. FQM has provided Tertiary with an extensive exploration database for Mushima North which includes airborne magnetic and electromagnetic geophysical data, as well as 500m spaced reconnaissance soil sample analytical results. Additional historical data for the area was made available by JAW Consulting LLC of Golden, Colorado which was commissioned by the Company to compile historical data and provide a detailed interpretation and targeting report. The JAW targeting report has drawn on historical exploration from the 1970s onwards by Roan Consolidated Mines, African Minerals, Zamanglo Prospecting Ltd. and BHP Billiton. The latter was exploring for IOCG deposits (a class of mineral deposit that includes some of the largest in the world, including Olympic Dam in South Australia). BHP planned two holes to test for IOCG mineralisation at target C1 but terminated all exploration in Zambia in 2012 without drilling the planned holes. Further details of the targets generated by this report can be found in the Company's news release of 1 June 2023. Targets A1 and A2 were identified from wide spaced reconnaissance soil sampling carried out by FQM. In September 2023, the Company contracted Geo-Junction Consulting Limited to perform a soil sampling programme at Mushima North to cover the C1, A1 and A2 targets. Positive results from target C1 were released on 5 October 2023. This release details the pXRF analytical results from targets A1 and A2. A total of 184 samples were collected on or around target A1 with a sample spacing of 200m. Soil samples were collected from the B-horizon1, dried and sieved to -180 micron. The sieved soil samples were placed into a sample cup and analysed using a pXRF instrument. Based on preliminary field pXRF analysis infill sampling was then carried out on 100mx 100m spacing with three 400m spaced lines sampled at 50m spacing. pXRF results from target A1 indicate a broad northeast striking copper-in-soil anomaly which, at a 80ppm copper cut off, covers an area approximately 3km long by up to 1.5 km wide. Within this area soil samples average 148ppm and peak at 280ppm copper. The A1 soil anomaly has a high-grade core at its north end where all soil values are in excess of 200pppm copper over an area 400m x 150m and average 231ppm copper. pXRF results from target A2 show very high copper-in-soil values of up to 1,239ppm. However, the high values are confined to organic rich sediments at the edge of a dambo (an area of shallow wetland). It is most likely that copper in these sediments is a result of hydromorphic concentration of copper in groundwater sourced from a copper-rich area, possibly the sources of the A1 copper anomaly some 3km distant. The A1 and A2 copper-in-soil anomalies have a favorable structural setting for mineralisation and the A1 anomaly is a further high priority for follow up drilling. During the field work at targets A1 and A2, samples containing visible spotty copper minerals malachite and chrysocolla were found when field checking an area 2 km west of target A1 where an electrical conductor had been identified by a previous explorer in an area underlain by iron-rich conglomerates. These conglomerates stretch over a 6 km strike length and are coincident with a low-level gravity anomaly. Surface samples contained up to 0.43% copper (average of three pXRF readings per sample). Soil samples around this new occurrence were not anomalous but the new find warrants further follow-up mapping and sampling.공시 • Oct 07Tertiary Minerals plc Announces First Soil Sampling Results from Mushima North Copper Project, ZambiaTertiary Minerals plc announced positive follow-up results from portable XRF ("pXRF") analysis of soil samples at the C1 target area at its Mushima North Copper Project in Zambia, one of a number of targets covered in a recent soil sampling campaign. Key Points: Target C1 is permissive for Iron-Oxide-Copper-Gold ("IOCG"1) style and traditional Copperbelt sediment-hosted mineralisation. Includes a lone 1970s drill hole, RKN800, which, in resampling by Tertiary, contains 33m grading 0.24% copper from 122m to the end of hole in association with highly anomalous arsenic. 572 soil samples collected on 200m x 200m grid have defined a significant open-ended copper anomaly above 60ppm over 4km x 1.25km, with peak value of 211ppm copper proximal to RKN800. The highest copper-in-soil values are coincident with highest arsenic values in pXRF soil results; consistent with strongly anomalous arsenic in hole RKN800. A subset of samples will now be submitted for laboratory-based check analysis. pXRF results from additional target areas A1 and A2 are awaited and expected shortly.공시 • Sep 13Tertiary Minerals plc Announces Provisional Soil Sampling Results Mukai Copper Project, ZambiaTertiary Minerals plc announced that portable XRF analysis of soil samples has defined a substantial copper-in-soil anomaly at the Mukai Copper Project in Zambia. Key Points: A total of 526 samples were collected on a 300m x 100m grid infilled up to 100m x 50m and analysed in the field using a portable XRF instrument ("pXRF"). A large high-grade copper-in-soil anomaly is defined with values in excess of a 160ppm copper over an area of approximately 1,300m by 400m with a peak soil value of 1,660ppm copper (0.16%) and soil values averaging 252ppm (average of 63 samples). This high-grade anomaly is part of broader copper-in-soil anomaly defined by 162 samples containing greater than 80ppm copper and averaging 173ppm copper over an area of approximately 1,800m by 800m. Soil anomalies from past producing mines on the Copperbelt typically have thresholds in the range 50 to 150ppm copper, averaging 80ppm copper and peak values in the range 100-450ppm copper and averaging 210ppm copper. A subset of samples will now be submitted for laboratory-based check analysis. The option and earn-in periods at Mukai and Mushima North Projects have been extended by six months by agreement with local partner Mwashia Resources to account for earlier delays with forest permits. The Mukai Copper Project comprises Exploration Licence 27066-HQ-LEL which covers 55.4 km2 and is located 125km west of Solwezi in the north-western Province of Zambia. Tertiary Minerals plc's 96% owned subsidiary, Tertiary Minerals (Zambia) Limited, is currently earning up to a 90% interest from local partner Mwashia Resources Ltd. The Company has now agreed to extend the option-earn-in period by six months to account for delays experienced earlier this year in obtaining forest permits at Mukai and Mushima North. Geologically the Mukai Project is located in the Domes Region of the Central African Copperbelt and it encompasses Lower Roan Subgroup rocks which are part of the southern flank of the highly prospective Kabompo Dome. The project lies directly adjacent to First Quantum Minerals Limited's ("FQM") Trident Project licences which include the recently opened Enterprise nickel mine and the large producing Sentinel (Kalumbila) copper mine, located 8km south and 18km southeast of the Mukai licence, respectively. The Company has a data sharing and technical cooperation agreement with FQM for the Mukai and Mushima North Projects, further details of which are given in the RNS of 15 September 2022. The impetus for the soil sampling programme at Mukai was the interpretation of regional historical exploration results provided by FQM where copper-in-soil anomalies and significant drill intersections of copper occur in a stratigraphic package which extends into the licence area. The Company contracted Geo-Junction Consulting Limited to perform a soil sampling programme at Mukai with work commencing in late-August 2023. A total of 311 soil samples were collected in a first pass soil sampling programme on north-south sampling lines with a sample spacing of 100m and line spacing of 300m. Soil samples were collected from the B-horizon, dried and sieved to -180 micron. The sieved soil samples were placed into a sample cup and analysed using a pXRF instrument to guide infill sampling. Initial pXRF results were reviewed in the field and a total of 206 further samples were collected by infilling the first pass grid at 150m line spacing and an offset 100m sample spacing. In the areas of the most significant copper-in-soil anomalies the infill samples were collected on a much tighter 50m by 100m grid. As a guide to the significance of soil sampling results, the Company notes2 that B-horizon soil anomalies for freely drained soils in the vicinity of various ore zones at current and past producing mines on the Copperbelt have thresholds in the range 50 to 150ppm copper, averaging 80ppm copper and peak values in the range 100-450ppm copper and averaging 210ppm copper. In addition, published data3 for the giant Sentinel copper deposit (>1 billion tonnes grading 0.51% copper, located close the Company's Mukai Copper Project in northwest Zambia) shows that the median copper value for soil samples collected over the sub-cropping expression of the orebody was 120ppm and only one soil sample exceeded 500ppm copper. Initial pXRF results from the Mukai Copper Project indicate a broad northwest striking anomaly approximately 1,800m long and 800m wide comprising 174 soil samples with copper values in excess of 80ppm. Soil samples in this broad anomaly contain an average copper value of 164ppm. Within this, a higher-grade core strikes northwest, following the favourable stratigraphy, and has dimensions 1,300m long and 400m wide comprising 71 soil samples averaging 226ppm copper and having a peak value of 1,660ppm copper (0.16% copper). The Company will send a subset of samples for traditional laboratory-based analysis as a check on these pXRF results.공시 • Aug 10Tertiary Minerals plc Provides Exploration UpdateFollowing the receipt of forest permits announced on 31 July 2023, Tertiary Minerals plc announced the start of soil sampling and to provide the following update on its Zambian copper exploration projects. Konkola West Project: Interpretation of airborne geophysical data provided by KoBold Metals has now identified areas in the north and northwest of the licence where the target Lower Roan formation - the main host to copper mineralisation on the Zambian Copperbelt - may be shallower and less steeply dipping than on the eastern side of the licence. Soil sampling is now underway to explore higher up in the sequence with approximately 260 soil samples due to be collected over the next few days. Soil samples will be analysed in the field using a portable XRF ("pXRF") analyser and follow up infill sampling will be carried out as appropriate. Konkola West lies immediately west of the Konkola-Lubambe-Musoshi copper mining licences and potentially contains downdip extensions of the laterally continuous Lower Roan ore shale horizon on the east side of the licence. Mukai Project: Soil sampling will commence at Mukai immediately after completion of work at Konkola West. Mukai adjoins First Quantum Minerals' ("FQM") Trident Project licences which include the large Sentinel copper mine and the recently opened Enterprise nickel mine. Approximately 310 soil samples will be collected on a 300m x 100m grid with additional infill sampling to test a historic soil anomaly in favourable stratigraphy along strike of FQM's Tirosa Prospect where FQM has drilled up to its licence boundary with Mukai. Mushima North Project: Mushima North is located east of the high grade Kalengwa Copper Mine and numerous targets have been identified for both iron-oxide-copper-gold ("IOCG") mineralisation and conventional Copperbelt style mineralisation. Soil sampling at Mushima North is currently scheduled to follow on from that at Mukai. Approximately 1,150 samples will be collected on 200 x 200m grids in three main target areas. Lubuila Project: Further to the announcement of 17 May 2023 the Company has now completed check analysis of soil samples collected earlier in the field season at Lubuila as well as an evaluation of multi-element geochemistry.Copper results have confirmed the previously reported anomalous copper results from Area C. However, the interpretation of multi-element analytical results suggests that the anomalous results are likely the result of lateritic enrichment rather than indicative of significant in-situ copper mineralisation.공시 • Jun 07Tertiary Minerals plc Provides Exploration UpdateTertiary Minerals plc announced that, via its local partner, Mwashia Resources, it has been provided with extensive geophysical exploration data for its Konkola West copper exploration project in Zambia by KoBold Metals. KoBold Metals, whose shareholders include Breakthrough Energy Ventures, a climate and technology fund founded by Microsoft's Bill Gates, and backed by Amazon's Jeff Bezos and Virgin's Sir Richard Branson, and mining giant BHP, is investing USD 150 million into the evaluation of the Mingomba Copper Deposit (Lubambe Extension Project) on the mining licence adjoining the Company's Konkola West exploration licence. The data now provided comprises airborne gravity, magnetic and radiometric data for the entire 72 sq.km. licence area and was collected by KoBold in 2021. This data set was collected as part of a wider regional airborne geophysical survey incorporating Konkola West and targeting down-dip and along-strike extensions of the contiguous Musoshi-Lubambe-Mingomba-Konkola copper deposits which host the Musoshi Mine in the Democratic Republic of the Congo and the Lubambe and Konkola mines in Zambia. Together these deposits define a continuous zone of mineralisation over 15km long with a pre-mining endowment of over 775 million tons grading 2-3% copper. Konkola West is located approximately 2,000 metres southwest of the Mingomba deposit which currently has a resource of 250 million tonnes with a mean grade of 3.8% copper.공시 • Jun 01Tertiary Minerals plc Releases Separate Project Focus Presentation for Its Mushima North Project in ZambiaTertiary Minerals plc announced that further to the Company's announcement of 28 April 2023, advising of favourable copper analytical results from sampling of core from historic drill hole RKN800, the Company is now releasing a separate "Project Focus" presentation for its Mushima North Project in Zambia. Mushima North is one of five projects in Zambia where Tertiary is exploring for copper, and one of two projects which benefit from the technical cooperation and data sharing agreement with leading copper producer First Quantum Minerals ("FQM"). The Project lies to the east of the high grade Kalengwa mine (past production 4 million tons grading 5.2% Cu and 40 g/t Ag and pre-mining reserve of 600,000 tons grading 16% copper) which was discovered by drill testing a coincident copper soil anomaly and gravity anomaly. FQM has provided its extensive database for Mushima North which includes airborne magnetic, electromagnetic and radiometric geophysical data as well as 500m spaced reconnaissance soil sample analytical results. Additional historical data for the area was made available by JAW Consulting LLC ("JAW") of Golden, Colorado which was commissioned by the Company to compile historical data and provide a detailed interpretation and targeting report. The JAW targeting report has drawn on historical exploration from the 1970s onwards by Roan Consolidated Mines, African Minerals, Zamanglo Prospecting Ltd. and BHP Billiton. The latter was exploring for iron-oxide-copper-gold ("IOCG") deposits, a class of mineral deposit that includes some of the largest in the world, including Olympic Dam in South Australia. The two highest priority targets are: O Target C1 - A prominent gravity high defined by BHP Billiton's Falcon airborne gravity survey with a coincident copper soil anomaly. The wide, low-grade, intersection of copper mineralisation recently announced from resampling core from drill hole RKN800 sits on the margin of the gravity anomaly making this an exciting target for follow up. Drill hole RKN800 pre-dates BHP Billiton's gravity survey. The C1 gravity anomaly was designated as an IOCG drill target by BHP Billiton, but never tested. Target A1 -A 1.7km long copper soil anomaly with values up to 350ppm copper (in portable x-ray fluorescence analysis) defined by 500m spaced samples and supported by coincident arsenic and zinc anomalies. This is a target for more conventional Copperbelt style mineralisation.공시 • May 18Tertiary Minerals plc Announces the Completion of Its Recently Announced Soil Sampling Programme At the Lubuila Copper ProjectTertiary Minerals plc announced the completion of its recently announced soil sampling programme at the Lubuila Copper Project. Highlights - Lubuila Copper Project: Planned soil sampling programme completed inclusive of additional follow-up sampling based on in-field portable X-Ray Fluorescence (pXRF1) analytical results. 425 soil samples collected across three separate grids targeting two untested areas of interpreted Lower Roan Group sediments (Areas A and B) and a historical copper-in-soil anomaly at Area C in Upper Roan Group sediments. Preliminary results indicate a large open-ended copper-in-soil anomaly defined over an area of approximately 1,000m x 680m at Area C with a peak copper value of 306 ppm and an average value of 125ppm Cu. Sample subset to be sent for traditional wet geochemical ICP analysis for data validation and interpretation.공시 • Jan 18Tertiary Minerals plc Announces Laboratory Check Analytical Results on Soil Samples from the Jacks Copper Project in ZambiaTertiary Minerals plc announced that laboratory check analytical results on soil samples from the Jacks Copper Project in Zambia have confirmed and enhanced the provisional results previously reported based on portable XRF analyses taken in the field. Key Points: Laboratory check multielement analytical results now received for 107 soil samples from 4 sample grids. Laboratory results show excellent correlation with previously reported field pXRF results. New scandium analyses (not available with pXRF analysis) allows evaluation of key copper:scandium ratios. High Cu:Sc ratios are considered indicative of hydrothermal copper sulphide mineralisation elsewhere in Zambia. The high Cu:Sc ratios obtained from the soil samples taken over copper sulphide mineralisation intersected in Company's 2022 drill programme at Area D validate the application of the Cu:Sc ratio and both enhance and extend the Area D soil anomaly beyond the area drilled. Laboratory analyses for 27 contiguous soil samples along a check profile in Area C exhibit high Cu:Sc ratios for a strike length of approximately 1 km and make Area C another priority for drill testing.공시 • Dec 12Tertiary Minerals plc, Annual General Meeting, Feb 16, 2023Tertiary Minerals plc, Annual General Meeting, Feb 16, 2023, at 10:00 Coordinated Universal Time.

공시 • Nov 01Tertiary Minerals plc Announces Upcoming Phase 3 Drill Programme At Target A1, Mushima North Project, ZambiaTertiary Minerals plc announced details of the upcoming Phase 3 drill programme at Target A1, its silver-copper-zinc prospect within the Mushima North Project ("Mushima North" or the "Project"). Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia, and Target A1 is a polymetallic, silver-copper-z Inc. prospect located 28km to the east of the historic Kalengwa copper-silver mine which is currently under redevelopment. Highlights: Planned drilling programme of approximately 1,000m of Reverse Circulation drilling. Drilling to test: further lateral extensions of the known mineralisation, particularly around the high-grade silver and copper mineralisation in the north. the continuity of mineralisation between wider-spaced drill lines, by obtaining additional mineralisation intersections. the depth extension of the known mineralisation. Phase 2 drilling of this target in mid-2025 returned drill intersections including (downhole widths, true widths unknown): 58m at 49 g/t Ag, 0.26% Cu and 0.16% Zn (72 g/t Ag equivalent or 0.94% copper equivalent) from 8m downhole (hole 25TMNAC-038). Including: 20m at 86 g/t Ag, 0.,44% Cu and 0.24% Zn from 46m downhole. Drilling again before the rains, rather than waiting until the start of the next dry season in March-April next year, shows resolve to aggressively advance this Project and add shareholder value. "Target A1 now has a surface footprint of approximately 450m by 400m, with mineralisation intersected to a vertical depth of up to 84m. However, the mineralisation remains open to the north/northwest, south/southeast and at depth. This drill programme will test the potential continuation of mineralisation along strike and at depth, as well as providing additional infill drilling. This work is aimed at bringing closer to goal of producing a maiden mineral resource in the next 12 months. Drilling Programme A programme of approximately 1,000 m of Reverse Circulation ("RC") drilling is planned as a series of east-west drill lines spaced approximately 100m apart (north-south). Holes will be collared approximately 50 to 100m apart along the east-west lines and drilled to a nominal depth of approximately 100m. De De De De Deceal holes (approximately 150m) will also be undertaken in key areas to further understand the potential continuation of mineralisation at depth. The drill programme at Target A1 is designed to test: further lateral extensionsof the known mineralisation, particularly across the high-grade silver and Copper mineralisation previously intersected in drillhole 25TMNAC- 038; the continuity of mineralisation between wide-spaced drill lines, By obtaining additional mineralisation intersections; the depth extension of the known Mineral Resource Estimate, if future drilling results warrant such an approach. The drill programme is being conducted by Ox Drilling which also completed the Phase 1 and Phase 2 drill programmes. The drill programme is expected to commence in early November, will take approximately 2 weeks to complete and is planned to be finished prior to the on-set of the heavy rains in the area which will inhibit further on-the-ground exploration until March-April 2026. Samples will be initially analysed on site using a portable X-Ray Fluorescence ("pXRF") analyser for copper and zinc. Phase 1 drilling (1,486m) in 2024 targeted the copper-in-soil anomaly and returned broad but generally low-grade copper mineralisation as reported in the news release dated 28 October 2024 (e.g. 57m at 0.20% Cu from 14m downhole, hole 24TMNAC-004). Higher grade copper mineralisation was also intersected within these broader zones (e.g. 6m at 0.58% Cu within 35m at 0.21% Cu within 35m at 22m downhole, from 22m downhole, hole 24m downhole, hole 24 TMNAC-024).

공시 • Oct 11Tertiary Minerals plc Provides Update on Target A1 Prospect Located Within Its Mushima North ProjectTertiary Minerals plc provided the following summary of recent news highlighting the Target A1 prospect located within its Mushima North Project ("Mushima North" or the "Project"). Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia. Target A1 is a polymetallic, silver-copper-zinc prospect located 28km to the east of the historic Kalengwa copper-silver mine which is currently under redevelopment. Highlights: Near surface (from 2m) mineralisation identified up to a depth of 84m with a surface footprint of approximately 450m by 400m. 73m at 32 g/t Ag, 0.16% Cu and 0.24% Zn (49 g/t Ag equivalent or 0.64% copper equivalent) from 11m downhole (hole 25TMNAC-025). Including: 21m at 66 g/t Ag, 0.,21% Cu and 0.30% Zn from 50m downhole. Elevated values of additional critical metals, including antinomy (up to 0.21%) and gallium (up to 40 g/t), as well as bismuth (up to 991 g/t). Multiple targets defined based on regional geochemical and geophysical targets still to be drill tested located within 12km of Target A1. Located only 28km east of the Kalengwa copper-silver Mine (approx. 4Mt @ 5.2% Cu, 40 g/t Ag) and with a similar geological setting. Located in the Iron-Oxide-Co Copper-Gold ("IOCG") region of northwestern Zambia. Highly prospective for not only IOCG but also sedimentary copper and polymetallic occurrences. Target A1 Target A1 is a large copper-in-soil anomaly (3.1km by 1.7km) with copper values up to 302ppm (per Portable X-Ray Fluorescence, "pXRF") associated with a 1.7km by 0.5km zinc- and coincidental 1.3km silver-in-soil anomaly. Phase 1 drilling (1,486m) in 2024 targeted the copper-in-soil anomalies and returned broad but generally low-grade copper mineralisation as reported in the news release dated 28 October 2024 (e.g. 57m at 0.20% Cu from 14m downhole, hole 24TMNAC-004). Higher grade copper mineralisation was also intersected within these broader zones (e.g. 6m at 0.58% Cu within 35m at 0.21% Cu, from 22m downhole, hole 24 TMNAC-024). Drilling over the silver- and zinc-in-soil anomalies (drill line: 8506925N) to the east identified wide and thick, near surface silver mineralisation associated with low-grade copper and/or zinc mineralisation. The Phase 2 drill programme (1,116m) targeted the silver and zinc-in soil anomaly. The silver mineralisation has now been confirmed to extend approximately 450m northwest-southeast and by 400m northeast-southwest and to a depth from near surface to 84m and remains open both to the north/northwest, south/southeast and at depth. Historically, gold is associated with other deposits and occurrences with the region, and as such gold analysis is also being undertaken on selected mineralised intersections to ascertain whether gold mineralisation is associated with any of the mineralisation styles interested so far. The company is also in discussions with external, independent consultants to determine whether or not there is currently enough drilling data to support the reporting of an Exploration Target (following the guidelines of The JORC Code) so as to provide an estimated range of in-situ tonnes and grade. Next steps would include additional drilling with aims to test: Further lateral extensions of the known mineralisation, particularly around the high-grade silver and copper mineralisation, and the continuity of the known mineralisation between wider-spaced drill lines, by obtaining additional mineralisation interceptsaced drill lines, and extensions at depth.
공시 • Sep 24Tertiary Minerals plc Announces Drilling Results for Further Three Holes from the Phase 2 Follow-Up Drill Programme At Target A1 At Its Mushima North Project in ZambiaTertiary Minerals plc announced drilling results for a further three holes from the Phase 2 follow-up drill programme at Target A1 at its Mushima North Project in Zambia. The analytical results from the new drillholes support the previously reported northern continuation of the thick near surface mineralisation defined by only one drill hole until now, extends over a width of approximately 300m. Silver mineralisation has now been intersected in drilling over a 350m by 300m area, and remains open to the north, south and at depth. Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia. Target A1 is a polymetallic, silver-copper-zinc prospect located 28km to the east of the historic Kalengwa copper-silver mine which is currently under redevelopment. Including: 15m at 63g/t Ag, 0.13% Cu and 0.56% Zn from 33m downhole. And: 16m at 1.59% Zn from 56m downhole. Mineralisation, including higher grade zones, remains open to the north, South and at depth. Results include the highest grades of zinc (3.35%) and antimony (0.21%) intersected to date from certified laboratory analytical results on the Project. Additional drill hole results expected in the coming weeks testing both northern and southern continuation of mineralisation. Initial mineralogical/metallurgical work now underway. Phase 2 Drill Programme As previously reported, the Phase 2 drill programme consisted of 1,116m of combined Air Core ("AC") and Reverse Circulation ("RC") drilling along a series of east-west drill lines spaced between 100m and 250m apart, north-south. Holes were collared approximately 100m apart along the east-west lines and drilled to the maximum depth possible at the time based on the drill rig capabilities and geological ground conditions (the bit refusal depth). The deepest drill hole in this programme was 99m and the average hole depth 70m. Combined Phase 1 and 2 drilling covers a surface footprint of approximately 1,680m by 550m. The Project's western boundary lies 20km to the east of the Kalengwa copper-silver Mine in northwest Zambia, one of the highest-grade copper deposits ever to be mined in Zambia (approximately 4 million tonnes at 5.2% copper and 40-80 g/t silver). In the 1970s, high-grade ore, reportedly averaging approximately 11% copper, was trucked for direct smelting at other mines in the Copperbelt. The Kalengwa mine is currently under redevelopment and is expected to produce 15,000 tonnes of copper annually. Several prospective targets have been defined thus far within the Project based on reviews of historic geochemical and geophysical survey data against the current exploration model developed by Tertiary (Targets A1, A2, B1, B2, B3 and C1). At the end of the summer 2024, Tertiary completed an initial (Phase 1) 25 AC drill hole programme (1,274m) to test parts of geochemical (copper-in-soil) anomalies at Targets A1 and C1. This limited and shallow drilling indicated wide downhole intervals of largely coincised by the current exploration model.
공시 • Aug 13Tertiary Minerals plc Announces Completion of Phase 2 Drill Programme at Target A1, Mushima NorthTertiary Minerals plc announced the completion of the follow-up drill programme at Target A1 at its Mushima North Project and preliminary results from portable X-Ray Fluorescence analysis of drill samples. Mushima North is located in the prospective Iron-Oxide-Copper-Gold region of Zambia. Target A1 is a polymetallic, silver-copper-zinc prospect. Phase 2 drilling is now complete, with 1,116m drilled over 16 holes. Extension of known mineralisation. Additional s ilver, zinc and copper mineralisation identified, extending the known mineralisation approximately 350m to the north and over a width of approximately 300m. Mineralisation remains open to the north and at depth. Results indicate the continuation of mineralisation to the north from the previous drilling for at least 350m, over broad intervals and with a continued width of approximately 300m. Higher copper values than previous results, such as 58m at 0.27% copper from 7m downhole, including 8m at 0.79% copper are particularly encouraging. Silver results from the pXRF analyser, while only indicative, do suggest the continuation of the silver mineralisation identified in the previous drill programme to the north. The preliminary results from the Company's internal analysis using a pXRF analyser indicate the continuation of mineralisation for at least 350m to the north of the previously reported drilling with significant silver, zinc and copper values. Mineralisation has also been intersected deeper than previously, to a vertical depth of approximately 82m on drill line 8506925N. Drill holes to the south (lines 8506650N, 8506360N and 8505650N) returned anomalous values of zinc and copper, but below the Company's reporting cut-off grades of 0.2% and 0.1%, respectively. However, the potential extent of silver mineralisation in this direction is unknown at this stage as the pXRF results for silver are not sufficiently reliable to indicate average grades over known mineralised extents. Certified, independent laboratory analysis is currently underway to confirm copper and zinc values and to ascertain silver values along with other potential, important accessory metals including bismuth, antimony and gallium. The agreement is non-binding to any further agreement and there are no commercial restrictions for Tertiary, nor does FQM have a right of first refusal over the Project. At the end of the summer 2024, Tertiary completed an initial (Phase 1) 25 AC drill programme (1,274m) to test parts of geochemical (copper-in-soil) anomalies at Targets A1 and C1. This limited and shallow drilling indicated wide downhole intervals of largely coincidental copper, zinc and silver mineralisation at Target A1. Numerous other geochemical and/or geophysical targets (A2, B2, B3, C2) are yet to be drill tested. Drilling Programme A programme of 1,116m combined Air Core ("AC") and Reverse Circulation ("RC") has now been completed, with a series of east-west drill lines spaced approximately 250m apart (north-south). Holes were collared approximately 100m apart along the east-west lines and drilled to bit refusal depth (average hole depth 70m).

Aim to test along strike and downdip continuations of mineralisation at Target A1, where drilling of this target in late 2024 returned drill intersections including (downhole widths, true widths unknown): 57m at 25 g/t Ag, 0.20% Cu, 0.15% Zn from 14m downhole (24TMNAC-004). Including: 5m at 73 g/t Ag, 0.,16% Cu, 0.31% Zn from 69m downhole. Target A1 is located only 28km east of the historic Kalengwa copper-silver mine which is under redevelopment. Drilling Programme A programme of up to 1, 500m combined Air Core ("AC") and Reverse Circulation ("RC") drilling is planned as a series of east-west drill lines spaced approximately 250m apart (north-south). Holes will be collared approximately 100m apart along the east-west lines and drilled to a nominal depth of approximately 75m.

The drill programme at Target A1 is designed to: Test the silver- and part of the broader zinc-in-soil anomaly over approximately 1.6km of strike and up to 0.3 km width. Test the depth extension of mineralisation in key areas to a depth of up to 150m. Gain insights into the mineralisation styles and grade continuity. The drill programme is being conducted by Ox Drilling which also completed the initial drill programme undertaken last year. The drill programme started on 18 July and will take approximately 2-3 weeks to complete. Samples will be initially analysed on site using a portable X-Ray Fluorescence ("pXRF") analyser for copper and zinc. Selected mineralised intervals will also be submitted for external assaying at a certified laboratory for a suite of elements, including silver, copper, zinc, bismuth, antimony and gallium. The Project is under a technical cooperation agreement with First Quantum Minerals Limited ("FQM"), which allows Tertiary to benefit from FQM's historic exploration data in the area, as well as FQM's geological team's extensive experience and understanding of the area's geology. The agreement is non-binding to any further agreement and there are no commercial restrictions for Tertiary, nor does FQM have a right of first refusal over the project. At the end of the summer 2024, Tertiary completed an initial 25 AC drill programme (1,274m) to test parts of geochemical (copper-in-soil) anomalies at Targets A1 and C1. This limited and shallow drilling has indicated wide downhole intervals of largely coincidental copper, zinc and silver mineralisation at Target A1. Numerous other geochemical and/or geophysical targets (A2, B2, B2, B3, C2) are yet to be drill tested.
공시 • Jul 08Tertiary Minerals plc Announces Details of the Upcoming Drill Programme At Target A1, Mushima North ProjectTertiary Minerals plc announced details of the upcoming drill programme at Target A1, Mushima North Project ("Mushima North" or the "Project"). Highlights: Planned drilling programme of up to 1,500m Air Core/Reverse Circulation drilling at Target A1. Drilling to test the along strike continuation of the coincidental 1.3km by 0.3km silver- and zinc-in-soil anomaly within the broader, kilometre-scale copper-in-soil anomaly. Initial drilling of this target in late 2024 returned drill intersections including (downhole widths, true widths unknown): 57m at 25 g/t Ag, 0.20% Cu, 0.15% Zn from 14m downhole (24TMNAC-004). Including: 26m at 36 g/t Ag, 0.,20% Cu, 0.20% Zn from 45m downhole. Many of these holes ended in mineralisation suggesting further depth potential. The programme will test the full extent of this anomaly over an area of approximately 1.5km by 0.3km and with additional deeper holes to test the depth potential. Drilling Programme A programme of up to 1, 500m combined Air Core ("AC") and Reverse Circulation ("RC") is planned as a series of east-west drill lines spaced approximately 250m apart (north-south). Holes will be collared approximately 100m apart along the east-west lines and drilled to a nominal depth of approximately 75m. Deeper holes (using RC) will also be undertaken in key areas to further understand the potential continuation of mineralisation at depth. The drill programme at Target A1 is designed to: Test the silver- and part of the broader zinc-in-soil anomalies over approximately 1.6km of strike and up to 0.3 km width. Test the depth extension of mineralisation in key areas to a depth of up to 150m. Gain insights into the mineralisation styles and grade continuity. The drill programme is being conducted by Ox Drilling which also completed the initial drill programme undertaken last year. The drill programme is expected to commence in mid-July and will take approximately 2-3 weeks to complete. Samples will be initially analysed on site using a portable X-Ray Fluorescence ("pXRF") analyser for copper and zinc. Selected mineralised intervals will also be submitted for external assaying at a certified laboratory for a suite of elements, including silver, copper, zinc, bismuth, antimony and gallium. Target A1 is a large (3.1km by 1.7km) copper-in-soil anomalies with copper values up to 350ppm (via pXRF analyser) associated with a 1.7km by 0.5km zinc- and coincidental 1.3km By 0.3km silver-in-soil anomalies. The Project is under a technical cooperation agreement with First Quantum Minerals Limited ("FQM"), which allows Tertiary to benefit from FQM's historic exploration data in the area, as well as FQM's geological team's extensive experience and understanding of the area's geology. The agreement is non-binding to any further agreement and there are no commercial restrictions for Tertiary, nor does FQM have a right of first refusal over the project.
공시 • Jun 19Tertiary Minerals plc Provides Project Summary Highlighting Its Jacks ProjectTertiary Minerals plc provided the following project summary highlighting its Jacks Project ("Jacks" or the "Project"), one of five prospective projects Tertiary currently holds within key locations in Zambia targeting copper and associated metals (silver, zinc, cobalt). Highlights: Targeting sedimentary copper within the Lower Roan Subgroup, south of the Central African Copperbelt, within an underexplored region. Acquisition of regional and local exploration datasets, including regional soil sampling by First Quantum Minerals and historic drilling of key copper-in-soil targets. Significant fold structure identified with several discrete copper-in-soil anomalies along fold limbs (approximately 18km strike length). The Jacks Project is located in an underexplored but highly prospective region to the southeast of the world-class Central African Copperbelt. Acquisition of historic regional and local datasets, including drilling, has enabled the project to be fast-tracked and initially de-risked. Geological map of the Jacks Project showing the locations of the priority targets along the large-scale Central African Copperbelt. The Project is held through Group company Tertiary Minerals (Zambia) Limited (which in turn is 96% owned by Tertiary Minerals plc) and local partner, Mwashia Resources Limited. The area was subject to further exploration in the 1990s by Caledonia Mining Corporation ("CMC") which conducted aeromagnetic surveys and the geochemical sampling (1000m by 100m grid) which identified the copper-in-soil anomaly commented upon above. Following the delineation of the prospective areas, CMC entered into a joint venture earn-in agreement with Cyprus AMAX Minerals ("Cy Cyprus"), a major US-based mineral exploration and mining company. The 1997 exploration programme included infill geochemical sampling, a ground-based magnetic survey, Induced Polarisation survey and a 19-hole Reverse Circulation ("RC") percussion drill programme (2,170m). A further programme of six diamond drill holes ("DD") totaling 1,378m was completed in 1998 to test the along strike and down dip extensions to the previously intersected mineralisation as well some of the soil anomalies. The historic drilling results suggest the presence of two separate zones of copper mineralisation within the fold hinge area from near surface and with significant depth potential. Shallow intersects include: 0.76% copper over 12m from 18m downhole (KJ13). 0.35% copper over 10m from 67.5m downhole (KJD5). 22JKDD04 was another step-out hole, drilled approximately 160m east of 22JKDD01 and 170m south of 22JKDD03. A broad mineralised zone was intersected: 0.8% copper over 14.0m from 7m downhole, including two higher grade intersections: o 1.7% copper over 2.0m grading from 27m downhole, and o 1.0% copper over 5.0m from 35.0m downhole. Summary of drill assay results from the initial Tertiary drilling programme (2022) at the fold hinge (Jacks Project). Note to Table 2: Calculated intersections (down hole, true width unknown) are weighted averages using a cut-off grade of 0.2% copper. Project Summary The Jacks Project is located In an underexploring but highly prospective region to the Southeast of the world-class Central Africa Copperbelt. Acquisition of historic Regional and local datasets, including drill, has enabled the project to been fast-tracked and initially De-risked. Geological map of the Jacks Project show the locations of the priority target along the large-scale fold of the large-scale fold of prospective Lower Roan Subgroup geology. Historic drilling, as well as recent drilling undertaken by Tertiary, confirms the potential of the Project to host both shallow, lower-grade and deeper, higher-grade copper mineralisation. Limited drilling by Tertiary has intersected copper mineralisation between approximately 25m and 100m vertical depth from surface. The Project Summary The Jacks Project (Licence 27069-HQ-LEL) is approximately 70.6km2% copper mineralisation is approximately 70.6km 2 in size and is approximately 70.6km and is approximately 70.6 km2% copper mineralisation.6km2km2.6km2 in size and is located within the Project to the Project to host both shallow-grade and is approximately 70.0km2% copper mineralisation of the Project to host both deep-grade and is located within the Project is located within the Project (LEL) is located within the Project (L) is located within the Company is approximately 70.6km3km2% copper mineralisation. 6km2 in size and is approximately 70km2km2% copper mineralisation and is approximately 70.6 kilometres and is approximately 70.6m.

공시 • Apr 14Tertiary Minerals plc Provides Update on the Mukai Copper Project, ZambiaTertiary Minerals plc provided the following update on the Mukai Copper Project ("Mukai" or the "Project"), Zambia. The Project is under agreement with First Quantum Minerals Limited ("FQM") which is managing the exploration on the Project during its due diligence period. The Project lies adjacent to FQM's Trident Project which includes both the Sentinel Copper and Enterprise Nickel Min es. Highlights: Completion of initial scout drilling programme of three diamond drill holes for a total length of approximately 554m. Near surface anomalous (>500 ppm) copper mineralisation intersected, including: 0.12% Cu over 3.8m from 1.6m downhole (TARDD0023). 0.17% Cu over 2m from 4m downhole (TardD0024). Near surface and thick intervals of anomalous (>500 ppm) nickel mineralization intersected, including: 558 ppm Ni over 63.1m from 10m downhole. Exploration programme/next steps currently under review.
공시 • Mar 31Tertiary Minerals plc Provides Drilling Update, Konkola West Copper ProjectTertiary Minerals plc provided the following update on the current drill programme being undertaken by a subsidiary of KoBold Metals ("KoBold") at its Konkola West Copper Project ("Konkola West"), Zambia. KoBold has the right to earn into the project by drilling two drill holes for a minimum of 2,000m. KoBold is targeting the potential continuations of mineralisation being mined at the world-class Musoshi, Lubambe and Konkola Mines, which had a pre-mining combined endowment of over 775Mt grading 2-3% copper. KoBold's Mingomba copper project is located approximately 5km to the northeast of the Project. Hole KWDD001 Drilling of hole KWDD001 has now been concluded after continued technical difficulties and limited advancement of the hole since the last update (20 February 2025) and having reached a down-hole depth of 2,711.1m. While the hole did not reach the targeted horizon (Ore Shale, Copperbelt Orebody Member), the geological data collected as part of the drilling has been instrumental in better understanding the previously unknown, geological architecture of the basin and has been used to update KoBold's proprietary geological models. As such, the hole has significant geological value and data generated from this hole will continue to be processed and analysed to inform future drilling at Konkola West. Two zones of low-grade copper sulphide mineralisation were intersected in this hole. The drill core from this entire hole is being analysed at an independent laboratory and any significant results will be released in due course. In addition, a wireline downhole geophysical survey has been completed collecting magnetic, induced polarisation, resistivity and gamma-ray data as well as mapping fracture density. KWDD001 is believed to be the deepest mineral exploration drill hole to ever be drilled in the Zambian Copperbelt and marks a significant milestone within the industry. Hole KWDD002 Despite stopping short of the target horizon in hole KWDD001, the results were sufficiently encouraging for KoBold to drill a second hole. Drilling of this hole (KWDD002) started on 26 March 2025. The location, orientation and expected length is based on KoBold's updated model for the basin, based on their extensive regional dataset and understanding, with data from KWDD001 being crucial to this. The expected hole depth is planned to approximately 2,000m. Konkola West Drill Programme Konkola West (Licence 27067-HQ-LEL) is located approximately 5 km to the SW of KoBold's Mingomb a deposit, which forms part of the Lubambe-Mingomba-Konkola copper deposits of the Zambian Copperbelt. The aim of the drill programme is to test the potentialcontinuations of mineralisation being mined and the World-Class Musoshi, Lubambe, and Konkola Mines (combined pre-mining endowment of over 775 millions grading 2-3% Copper). KoBold's MingOMa project, is reported by KoBold to be one of the larger undeveloped copper deposits in the world. KoBold is using its propriety AI-driven models of the regional geology to support its mineral exploration targeting. Earn-In Agreements The Earn-In Agreement is between Tertiary Minerals (Zambia) Limited, its local partner, Mwashia Resources Limited, and KoBold Metals. Under the initial Earn-in Agreement, KoBold is required to drill two holes and a minimum 2,000m of drilling within 14 months of signing the Earn-in Agreement. This period has now been extended by 4 months to allow the drill the second hole, which is expected to be approximately 2000m. In addition, a provision of the Earn-In Agreement has been made to ensure that KoBold's newly granted adjacent Large Exploration Licence, 38615-HQ-LEL, will also be granted adjacent Large Exploration Licence.
공시 • Mar 17Tertiary Minerals plc Announces Additional Assay Results from Drilling At the Mushima North ProjectTertiary Minerals plc announced additional assay results from drilling at the Mushima North Project further to its announcement of 20 January 2025. The results identify a further wide drill intercept of silver mineralisation associated with previously reported copper-zinc mineralisation. Highlights: Results now available from samples from part of hole 24TMNAC006P (20-56m), located 50m west of previously reported silver mineralised hole 24TMNAC004. 30 g/t silver, 0.16% copper and 0.34% zinc over 36m, from 20m down hole. Including: 54 g/t silver,0.21% copper and 0.33% zinc over 12m, from 31m downhole. Including: 1m grading 176 g/t, 0.38% Cu and 0.29% Zn silver from 32m. 34 g/t silver and 0.12% copper and 0.3% zinc over 4m, from 52m. Previously reported analyses for these holes were for copper and zinc and were based on field portable X-Ray Fluorescence (pXRF) analysis which is not a suitable method for silver analysis. Silver mineralisation is now intersected in two holes 50 m apart. However, laboratory assay results for silver (and confirmation for copper and zinc) are still awaited for parts of both holes in addition to the entire lengths of a further five holes along the same drill line. The drill line targets part of a silver in-soil geochemical anomaly that is approximately 1.4km long and up to 300m wide and coincident with a broader zinc and copper anomaly. Previously released pXRF results for copper and zinc indicates many of the holes ended in mineralisation. The Mushima North Copper Project (Licence 27068-HQ-LEL) is held through Group company Copernicus Minerals Limited ("Copernicus") which is 90% owned by Tertiary Minerals (Zambia) Limited and 10% by local partner, Mwashia Resources Limited. The Project lies 20km to the east of the Kalengwa copper mine in northwest Zambia, one of the highest-grade copper deposits ever to be mined in Zambia. In the 1970s, high-grade ore, in excess of 26% copper, was trucked for direct smelting at other mines in the Copperbelt. The Kalengwa mine is now being reopened and is expected to produce 15,000 tonnes of copper annually. The Project is under a technical cooperation agreement with First Quantum Minerals Limited ("FQM"), which allows Tertiary to benefit from FQM's historic exploration data in the area, as well as FQM's geological team's extensive experience and understanding of the area's geology.
공시 • Feb 27Tertiary Minerals plc Provides Update on Brunton Pass Project – Drilling ResultsFurther to its announcement dated 16 December 2024, the Tertiary Minerals plc announced the results of drilling from the Phase 1 Drill Programme at its 100% owned Brunton Pass Copper-Gold Project in Nevada, USA. Highlights: Four reverse circulation percussion drill holes completed for a total of 890m in first pass drill programme. All four holes intersected thick intervals containing anomalous copper values associated with fresh and oxidised pyrite and trace chalcopyrite. Cumulative drill thicknesses up to 210m grading 170ppm copper (Hole 24TBPRC002) with values up to 0.19% copper over 1.53m. Anomalous copper values extend to at least 212m vertical depth, 630m east-west and 560m north-south. Surface mercury and arsenic indicator anomalies persist at depth. Deeper diamond drilling is justified to test the core of the target Induced Polarisation ("IP") geophysical anomaly. Petrographic and additional geochemical analysis planned to assist future drill targeting. A map and two cross sections can be found at the end of this release illustrating the exploration results to date. The Brunton Pass Project is located in central Nevada, USA, 25km northeast of the high-sulphidation epithermal Paradise Peak gold deposit that produced over 1.6 million ounces of gold, over 44 million ounces of silver and at least 457 tons of mercury. The Project was acquired in 2021 after sampling of prospector small-scale surface workings revealed high copper values. Mineralisation at Brunton Pass occurs within a series of limestones, siltstones and sandstones of the Triassic-age Luning Formation that have been widely converted by thermal metamorphism and metasomatism to hornfels and calc-silicate skarn units. These altered rocks form a 1.8km x 0.75km, uplifted "window" (horst block) in fault contact within younger Tertiary-age volcanic rocks. Evidence for an underlying body intrusive is found in surface outcrops of granite/granodiorite and at least two phases of diorite intrusion. Soil sampling has delineated several copper-in-soil anomalies with individual grades of up to 953ppm copper. The largest of these anomalies in the southwest quadrant of the property has dimensions of 340m x 310m and they are mainly coincident with areas where rock grab samples contain percent-level copper values in small prospecting pits. In 2022, the Company excavated two trenches in the area, T7 and T8, which encountered low-level copper mineralisation at surface including 27.4m grading 0.1% copper. Further details can be found in the news release dated 16 December 2024. Drill holes 24TBPRC001 and 24TBPRC002were drilled to test for mineralisation below the main copper soil anomaly and trenches T7 and T8. Hole 24TBPRC001intersected three intervals of anomalous copper with a cumulative downhole thickness of 123.45m and a weighted average grade of 149ppm copper. Mineralisation is mainly oxidised, but in the lower part of the hole the iron-sulphide mineral pyrite occurs with trace chalcopyrite. Sporadic quartz, gypsum and quartz-calcite veins were also intersected. The main host to mineralisation in hole 24TBPRC001 is a biotite-rich rock which at surface has been mapped as a diorite intrusive but which may also be a metamorphosed sedimentary rock. Further mineralogical work is required to make a definitive determination. Hole 24TBPRC002was drilled approximately 265m east of, and directed towards, hole 24TBPRC001. It intersected a sequence of sandstones and limestones, mainly altered to hornfels and calc-silicate rock. It intersected two main zones with anomalous copper values having a cumulative downhole thickness of 210m and a weighted average grade of 170ppm copper. A 1.53m interval grading 0.19% copper was intersected from 59.71m downhole and the hole ended in mineralisation at 252.98m depth. Drill Holes 24TBPRC003 and 24TBPRC004were drilled some 630m apart and were designed to test a north-south striking IP geophysical (chargeability) anomaly that stretches over several hundred metres and which is coincident with a broad zone of mercury and arsenic anomalies in soils and trenches. Hole 24TBPRC003was anomalous in mercury throughout its 137m length averaging 9.25ppm, which is approximately 450 times background levels of 0.02ppm mercury. The rocks were variably altered with hematite and manganese oxides within a mixed sequence of hornfels, calc-silicate rock and limestone. The hole was also targeting altered rocks adjacent to a granodiorite dyke which contained high gold values but the hole stopped short of target. Hole 24TBPRC004, drilled some 560m south of hole 24TBPRC003, also intersected anomalous mercury, with anomalous arsenic and copper and a cumulative downhole intersection of 132.69m grading 130ppm copper including 103.64m grading 142ppm copper, 488ppm arsenic and 3.5ppm mercury. Disseminated pyrite was present through most of the drill hole. Drilling has confirmed that the copper anomalies seen in surface soil samples and trench samples persist at depth to at least the lowest level tested in the current drilling (212m below surface in hole 24TBPRC002) and in an area 560m east-west and 560m north-south. This is a large body of rock containing anomalous copper values and, on the eastern side, anomalous indicator metals, mercury and arsenic. The Company's working thesis is that this large area may represent the halo to a buried porphyry copper deposit and that deeper drilling is justified.

공시 • Feb 20Tertiary Minerals plc Provides Update on Konkola West Copper ProjectTertiary Minerals plc provided the following update on its Konkola West Copper Project in Zambia where KoBold Metals Company has the right to earn into Large Exploration Licence 27067-HQ-LEL. Details of the Earn-In Agreement were outlined in the Company's news release dated 19 December 2023. Drilling of hole KWDD001 has advanced past 2,600m down-hole depth and is now drilling ahead in the Kitwe Formation which forms the upper part of the Lower Roan Subgroup and which, at its base, is host to the Ore Shale (Copperbelt Orebody Member) of the Zambian Copperbelt. The drill hole is currently in the Shale with Grit unit of the Kitwe Formation, the base of which is typically between 25-225m above the Ore Shale in the Konkola area1. If conditions and equipment allow, the planned completion depth for KWDD001 is 3,000m. Drilling has taken substantially longer than expected and KWDD001 has drilled deeper than originally planned. This is due to folding, possibly along an extension of the major Fitwaola fault system. Drilling also becomes progressively slower with depth due to the incremental time required to recover drill core from the drill face. Second Drill Hole KoBold has advised the Company that it plans to start drilling a second deep hole at Konkola West shortly after the completion of the first hole. A number of possible locations have been selected where the Lower Roan is now projected to be closer to the surface with a final location decision contingent on further geological interpretation of hole KWDD001. Further Agreements Under the Earn-in Agreement, KoBold is required to complete two holes and a minimum 2,000m of drilling within 14 months of signing the Earn-in Agreement. In the circumstances, Tertiary Minerals (Zambia) Limited and its local partner, Mwashia Resources Limited, have agreed with KoBold to extend this 14-month period by four months to allow time to start and progress drilling of the second hole. The parties have also signed a second agreement to give effect to a provision of the Earn-In Agreement to ensure that KoBold's newly granted adjacent Large Exploration Licence, 38615-HQ-LEL, will be also be held under the terms of the Earn-in Agreement for the benefit of all the parties.

공시 • Jan 21Tertiary Minerals plc Announces New Silver Discovery at Mushima NorthFurther to its announcement of 28 October 2024, and as a result of laboratory check analysis of drill samples, Tertiary Minerals plc announced the discovery of economically significant silver and cobalt mineralisation associated with previously announced copper-zinc mineralisation at its Mushima North Project in Zambia. Highlights: Four drill holes submitted for laboratory multi-element check analysis, three drill holes checked from Target A1 including: Hole 24TMN004 (Drill Line 1) - 59mgrading 25 grammes/tonne ("g/t") silver, 0.2% copper and 0.16% zinc from 10m to end of hole at 72m including: 26m grading 36g/t silver,0.20% copper and 0.20% zinc from 45-72m. Hole ended in mineralisation grading 49g/t silver, 0.24% copper and 0.15% zinc. Previously reported copper and zinc values confirmed by laboratory check analysis. Hole 24TMN024 (Drill Line 1): Significant cobalt associated with previously reported higher grade copper interval: 6m grading 0.08% cobalt, 0.58% copper from 47-53m. Entire hole, where check analyses are available, is anomalous in copper and cobalt: 74m grading 0.14% copper, 0.03% cobaltand 3g/t silver from 20m to 96m at end of hole. Hole also anomalous in nickel with best intersection of 4m grading 0.12% nickel, 0.09% cobalt, 0.18% copper and 5g/t silver from 42-46m. · Hole 24TMN016from Target C1 shows narrow intervals of low-grade gold mineralisation. · Silver-in-soil geochemical anomaly associated with Hole 24TMN004 evident in check soil analytical data - 1.3km long and open ended to the northeast and southwest. Repeat silver analysis on 14 check samples using a stronger acid digest method returned silver values 12% higher than those now being reported. Check Analysis of Drill Samples - New Results: Results are now available for five drill holes that were selected for check analysis. This included four holes from Target A1 (Hole Numbers 24TMN004, 6P, 11 and 24) and Hole TM24TMN16 from Target C1 (see accompanying map and drill section). Drill hole 24TMN006P was only analysed for gold. Check analysis for copper and zinc confirmed the previously reported results except for one interval for zinc in Hole 24TMN011 which requires further investigation (see accompanying table). Significant silver values were found throughout Hole 24TMN004 in broad association with copper and zinc whilst significantly anomalous cobalt and nickel and silver was found in hole 24TMN024 with the highest cobalt grades accompanying the highest copper grades. Target A1 was first defined by pXRF analysis of soil which defined a large copper-in-soil anomaly which was subsequently confirmed by laboratory check analysis of samples taken along three sample lines within the anomaly (see accompanying map). A review of the silver values in these check soil analyses has now revealed a silver-in-soil anomaly within the copper-in-soil anomaly that extends northeast-southwest for at least 1.3km across all of the three check lines. This silver anomaly is open-ended in both of these directions. The accompanying map and drill section illustrates that, of the drill holes selected for check analysis, only hole 24TMN004 was drilled within the silver-in-soil anomaly. However, The company anticipates that additional laboratory analysis of other drill holes on Line 1 that fall within the silver-in-soil anomaly may also reveal significant silver mineralisation. The map also illustrates that drill hole 24TMN024, whilst hitting a thick interval of lower grade silver, was likely drilled too far east, on the edge of the silver-in-soil anomaly and the current belief is that the two southerly drill lines (including Hole 24TMN011) were both drilled too far to the west to hit the main copper-zinc and silver targets. Check analysis of drill hole 24TMN016 at Target C1 area intersected two narrow intervals of anomalous gold in granite: 0.47g/t gold from 5-6m downhole and 0.25g/t gold from 22-23m and confirmed the previously reported narrow interval of copper mineralisation. As a further check on the silver values now being reported, fourteen samples were submitted for repeat analysis by a different laboratory method using a stronger acid digest for more complete dissolution of contained metals. The repeat analyses confirmed the silver discovery and returned 12% higher silver values on average.
공시 • Dec 17Tertiary Minerals plc Successfully Completes its First Drilling Programme at the 100% Owned Brunton Pass Copper-Gold Project in Nevada, USATertiary Minerals plc announced that further to its announcement of 15 November 2024, the company announced that it has successfully completed its first drilling programme at the 100% owned Brunton Pass Copper-Gold Project in Nevada, USA. All four of the planned drill holes were completed and over 700 samples have been submitted to an independent laboratory, Paragon Geochemical in Reno, Nevada, for analysis for base and precious metals. Results are expected in January 2025 and will be reported as soon as possible thereafter.
공시 • Nov 15Tertiary Minerals plc Commences at its 100% Owned Brunton Pass Copper-Gold Project in Nevada, USATertiary Minerals plc advised that drilling has commenced at its 100% owned Brunton Pass Copper-Gold Project in Nevada, USA. Detailed Information: The Brunton Pass Project is located in central Nevada 25km northeast of the high-sulphidation epithermal Paradise Peak gold deposit that produced over 1.6 million ounces of gold and over 44 million ounces of silver and at least 457 tons of mercury. The Project was acquired in 2021 after sampling of prospector small-scale surface workings revealed high copper values. Mineralisation at Brunton Pass is closely associated with hornfels, skarn and high-sulphidation-style epithermal alteration of a mixed sequence of Triassic aged carbonate and clastic sediments that form a 1.8km x 0.75km, uplifted "window" (horst block) in fault contact within younger Tertiary-age volcanic rocks. Evidence for an underlying body intrusive is found in surface outcrops of granite/granodiorite and at least two phases of diorite intrusion. Copper Target Soil sampling has delineated several copper-in-soil anomalies with individual grades of up to 953ppm copper. The largest of these anomalies in the southwest quadrant of the property has dimensions of 340m x 310m and they are mainly coincident with areas where rock grab samples contain percent-level copper values in small prospecting pits. In 2002, two trenches were completed for a combined length of 386m to further evaluate the main anomaly and wide intervals of low-grade copper observed in trenches T7 and T8: · 27.4m grading 1,010ppm copper (0.1% Cu) in T7, open to the east. 77.7m grading 473ppm copper in T8, also open to the east. These wide low-grade copper intervals are a possible halo to more significant mineralisation and suggest the possible presence of a deeper porphyry copper target. Two reverse circulation drill holes of 350-400m each are planned to test this target. Gold-Silver Target During soil sampling two large mercury and arsenic in soil anomalies were also defined in the eastern half of the property in a north trending zone with values up to 52 ppm mercury with the largest of these extending over an area approximately 500m x 500m. These anomalies are centred on a north trending zone of structural dislocation with a strike length of at least 1.2km. Two trenches (T1 and T11) tested the north and south ends of this mercury-arsenic soil anomaly and intersected substantial widths of hydrothermally altered rock with approximately 1,000 times background content of the gold indicator elements, arsenic and mercury: · 9.1m grading 1,930ppm arsenic and 102ppm mercury in T1. · 32m grading 1,622ppm arsenic and 110ppm mercury T11. The argillic alteration evident in T1 and T11 is similar to that seen at the Paradise Peak Gold Mine (smectite+quartz+/-opal). Trench T2, located between T1 and T11, intersected 2.65g/t gold over 2.7m. In early 2024, an IP Survey and Resistivity geophysical survey identified a coherent electrical chargeability anomaly, typical of sulphide mineralisation prospective for copper and/or gold, extending over 700m through all IP survey lines. The chargeability anomaly is spatially related to the previously identified copper-mercury-arsenic soil anomalies, the surface alteration zone in trench T11 and the gold-bearing zone in trench T2. Resistivity variations are conformable with surface geology and help map out subsurface geology. The chargeability anomaly and associated geochemical anomalies are a high priority drill target for epithermal gold and/or porphyry copper mineralisation and two reverse circulation drill holes are planned to test this target.
공시 • Nov 04Tertiary Minerals plc Commences Drilling At the Mukai Copper Project in ZambiaTertiary Minerals plc advised that First Quantum Minerals Limited ("First Quantum") has commenced drilling at the Mukai Copper Project in Zambia following the receipt of all necessary consents. The Company has received approval from the Department of Forestry to conduct further mineral exploration, including drilling, in the Licence area (the "Licence"). Consent has also been granted by the leadership of local tribal group, the Musele Royal Establishment ("Musele Chiefdom"), to conduct mineral exploration on the Licence. Phase 1 drill programme, now underway, will comprise up to 6 diamond drill holes, with drilling depths ranging between 350 and 400m. The drill programme will test beneath the large soil anomaly defined by Tertiary in 2023 which is contiguous with First Quantum's Tirosa Copper Prospect on the adjoining mining licence. Under the Company's agreement with First Quantum, First Quantum must define a minimum resource of 80,000 tonnes of copper before it can earn an interest in the Licence. The Licence lies adjacent to First Quantum's Trident Project which comprises various mining licences encompassing the producing Sentinel Copper Mine and the recently developed Enterprise Nickel Mine. The Sentinel processing plant has a processing capacity of 55 million tonnes of copper ore per year. The Licence renewal has been approved for an additional three years and is awaiting transfer to Copernicus Minerals Limited ("Copernicus"). Further details are given in the Company's news release of 6 June 2024. The Company's exploration at Mukai in 2023 resulted in the identification of a substantial copper-in-soil anomaly on the Licence. This soil anomaly occurs along strike from copper mineralisation that has been identified in past drill programmes at First Quantum's Tirosa Prospect, on its adjoining Trident Project area, which encompasses the Sentinel Copper and Enterprise Nickel mines. The Sentinel Mine was developed with a total investment of over USD 2.1 billion and is expected to produce around 235,000 tonnes of copper metal this year. The Enterprise Nickel mine is newly opened and expects to produce around 20,000 tonnes of nickel in 2024. Both deposits are sediment-hosted and occur in sedimentary basins formed on and around the Kabompo Dome. A similarly located basin hosts the Tirosa Prospect and continues into the Licence. As announced on 7 August 2024, Copernicus and First Quantum have signed a Binding Letter of Agreement ("BLA") allowing First Quantum to evaluate and earn an interest in the Licences by completing a minimum exploration expenditure of USD 1,500,000 during a 24-month due diligence period and by defining a minimum resource of 80, million tonnes of contained copper. In late August 2024, a series of meetings were held at the Department of Forestry's Solwezi District Office and the Lusaka headquarters to outline the proposed work programmes resulting in the submission of a formal application which has now been approved. In order to gain a Letter of Consent from the Musele Chiefdom, the Company met with Senior Chief Musele in September 2024 and as such were the first company to meet the Senior Chief Musele since the installation ceremony in July 2024. The Company hosted a community event where a presentation was made to the Musele Chiefdom to introduce the Company, the proposed exploration operations and address any concerns. A Letter of Consent has now been received from the Musele Chiefdom and, upon notification, First Quantum initiated drill preparation with the intention of completing a Phase 1 diamond drill programme. Phase 1 of the drill programme will comprise up to 6 diamond drilling holes to depths ranging between 350m and 400m on two fence lines. Drilling is now underway and will continue for so long as weather conditions permit following the onset of the wet season in Zambia.
공시 • Oct 16Tertiary Minerals plc Completes Inaugural Drill Programme At Its Mushima North Copper Project in ZambiaTertiary Minerals plc advise that the Company's inaugural drill programme at its Mushima North Copper Project in Zambia has now been completed. Summary: Drilling aimed to test the A1 and C1 coincident copper, zinc and arsenic soil anomalies defined by the Company's soil sampling programmes completed in 2023. Twenty-five aircore/reverse circulation drillholes completed to a maximum depth of 112m. Three drill traverses completed at anomaly A1, one drill traverse at anomaly C1. Portable X-Ray Fluorescence ("pXRF) analysis of drill samples now being completed, together with QA/QC checks. Selected samples will also be sent to an independent laboratory for check analysis. pXRF analytical results will be released as soon as possible. A plan showing the location of Mushima North drill holes can be found at the end of this release.
공시 • Sep 23+ 1 more updateTertiary Minerals plc Provides Update on Exploration Activities in Zambia and NevadaTertiary Minerals plc provided the following update on its exploration activities in Zambia and Nevada. Mushima North Copper Project (Zambia): The Mushima North Copper Project (Licence 27068-HQ-LEL) is held through Group company Copernicus Minerals Limited (‘Copernicus’) which is 90% owned by Tertiary Minerals (Zambia) Limited. Copernicus is in the process of taking a transfer of the licence through its agreement with licence holder, Mwashia Resources Limited. The project lies 20km to the east of the Kalengwa copper mine which is now being reopened and is expected to produce 15,000 tonnes of copper annually. Kalengwa was one of the highest-grade copper deposits ever to be mined in Zambia. In the 1970s high-grade ore, in excess of 26% copper, was trucked for direct smelting at other mines in the Copperbelt. Kalengwa was discovered by drill testing a coincident copper-in-soil anomaly and gravity anomaly and has characteristics of the Iron-Oxide-Copper-Gold (‘IOCG’) class of deposits. In 2023, following a detailed targeting project, Tertiary carried out soil sampling over the A1, A2 and C1 targets, defining significant copper in soil anomalies. A contract has now been signed with Ox Drilling for up to 2,500m of aircore drilling which will primarily test the large A1 soil anomaly in a number of drill traverses. The A1 copper-in-soil anomaly covers an area of approximately 3km by 1.5km and is considered prospective for traditional Copperbelt style mineralisation. Drill access and preliminary drill pad preparation have been completed. Drilling is expected to start today and run for approximately 2-3 weeks. Samples will be analysed in the field using a hand-held portable x-ray fluorescence (‘pXRF’) spectrometer with follow-up laboratory based check analyses. A geophysical programme is also being planned to better define the gravity and magnetic anomalies defined by BHP at Target C1. BHP had planned two holes in 2011 to test these anomalies for IOCG style mineralisation but terminated all exploration in Zambia prior to drilling these holes. The Konkola West Project comprises Exploration Licence 27067-HQ-LEL which covers 71.9 sq. km. and is located 18km northwest of Chingola in the Central African Copperbelt. KoBold has the right to earn-in to the project and is funding exploration costs. Further details of the agreement with Mwashia and KoBold can be found in the Company's announcement dated 19 December 2023. The Konkola West Project is targeting deep down-dip and along-strike extensions of the contiguous Lubambe-Mingomba-Konkola copper deposits to the west of the Licence and which extend north into the Musoshi mining complex in the Democratic Republic of the Congo. Together these deposits comprise a 15km-long continuous zone of mineralisation that contained a pre-mining endowment of over 775 million tonnes grading 2-3% copper. Konkola West is located approximately 2,000m southwest of the Mingomba deposit which lies between the Konkola and Lubambe mines and which is currently being evaluated by KoBold. KoBold has reported Mingomba to be one of the largest undeveloped copper deposits in the world. KoBold is committed under the earn-in Agreement to drill at least two holes for a minimum of 2,000m of drilling. Drilling of the first hole, KWDD001, commenced in mid-April and is continuing. The drilling is slow due to the depth of drilling (now in excess of 2,000m) and the technical challenges in drilling at such depths in new, undrilled areas. KoBold remains committed to continuing the hole until it reaches its target horizon or the limits of the rig's capabilities. The Mukai Copper Project (Licence 27066-HQ-LEL) covers 55.4 sq. km. and is located 125km west of Solwezi in the north-western Province of Zambia. It is currently being transferred to Copernicus. The licence is directly adjacent to FQM's Trident Project, which includes the recently opened 35 million tonne Enterprise Nickel Mine and the 894 million tonne Sentinel (Kalumbila) Copper Mine, located 8km south and 18km southeast of the licence, respectively. FQM has invested USD 2.1 billion in the Sentinel Copper Mine where the plant has the capacity to treat 55 million tonnes of ore per annum. The Mukai Project is also located just to the west of Arc Minerals' project area on the opposite flank of the Kabompo Dome, where Anglo American can earn a 70% interest from Arc Minerals through expenditure of USD 88.5 million, including USD 14.5 in cash payments. Copernicus has signed a binding letter of agreement (‘BLA’) giving FQM the right to earn up to an 80% joint venture interest in the Mukai Project. Copernicus is carried at a 20% equity level all the way through to the start of mining. Full details of the BLA are given in the Company's announcement dated 7 August 2024. In 2023, Tertiary carried out a detailed soil sampling programme which resulted in the identification of a substantial copper-in-soil anomaly on the Licence as described in the Company's announcement dated 12 September 2023. FQM is ready to start drilling this dry season provided the necessary local consents can be obtained in time. A two-phase, 12-hole diamond drilling programme has been planned to test the copper-in-soil geochemical anomaly. The Jacks Exploration Licence 27069-HQ-LEL covers 141.4 sq. km. and is located 85km south of Luanshya in the Central African Copperbelt. It is currently being transferred to Copernicus. Copper mineralisation occurs within the southern limb of a large asymmetric synclinal fold structure. Historical drilling and four holes drilled by Tertiary suggests that copper occurs in two separate mineralised horizons which may be discrete mineralised zones but could, alternatively be one refolded horizon. In October 2022, Tertiary carried out a programme of soil sampling to follow up unresolved copper-in-soil anomalies defined during wide spaced soil sampling by previous operators including Cyprus-Amax and FQM, as well as to guide follow-up drilling on the Jacks main prospect. The results of analysis have delineated significant copper-in-soil anomalies on a number of separate sampling grids with peak values ranging from up to 525ppm copper, a result that compares favourably with soil anomalies in the vicinity of various ore zones at current and past producing mines on the Copperbelt. A programme of pitting is now underway. Approximately 25 pits will be excavated over key soil sample locations to allow for decisions on follow-up drilling. Pit samples will be analysed by pXRF. The programme will take approximately 7 days to complete. The Brunton Pass Project is located in central Nevada, 25km northeast of the high-sulphidation epithermal Paradise Peak gold deposit that produced over 1.6 million ounces of gold and over 44 million ounces of silver and at least 457 tons of mercury.

공시 • Jul 29Tertiary Minerals plc Announces Completion of Its Soil Sampling Programme and Receipt of Field Analytical Results at its Mupala Copper Project in the Highly Prospective Kabompo Dome of the Northwestern Province, ZambiaTertiary Minerals plc announced the completion of its soil sampling programme and receipt of field analytical results at its Mupala Copper Project in the highly prospective Kabompo Dome of the Northwestern Province, Zambia. The Mupala Copper Project is located adjacent to the Anglo American/Arc Minerals Joint Venture ("JV") Project, where Anglo American has a right to earn a 70% interest through expenditure of USD 88.5 million, and 12 km west of the Company's Mukai Project. Geologically located on the west side of the Kabompo Dome, in the prospective Domes Region of northwest Zambia, which is host to multiple producing copper and nickel mines, including First Quantum Mineral's Trident Project which adjoins the Company's Mukai Project; A total of 684 soil samples collected on a 300m by 300m offset grid with infill sample spacing of 150m by 150m in areas of anomalous copper-in-soil. Copper-in-soil anomaly approximately 1,800m long by 600m wide identified with a peak value of 422 ppm copper determined by portable X-ray fluorescence (pXRF) analysis. The anomaly is consistent with historical exploration data and extends to the licence boundary with the Anglo American/Arc Mineral JV. A sub-set of samples will be submitted for check laboratory based geochemical analysis. The Licence is underlain by rocks of the prospective Lower Roan Subgroup and lies directly adjacent to the Anglo American/Arc Minerals joint venture area where Anglo American has the right to earn a 70%interest through expenditure of USD 88. 5 million. Approximately 12 km to the east lies the Company's Mukai Copper Project and First Quantum Minerals' Trident Project which is host to the Enterprise Copper and Sentinel Nickel Mines. Existing geological maps indicate that the licence covers some 16 km strike length of the main copper mineralised horizon in Zambia (Lower Roan Subgroup). Historical exploration records, albeit incomplete, identified a number of copper-in-soil anomalies which provided an initial focus for the Company's exploration of the Licence area. First pass soil samples were taken on a 300m by 300 m offset grid over the entire Licence area with samples collected from a depth of approximately 30cm in the B-horizon of the soil profile and dry-sieved to -180 micron. A subsample of the minus soil fraction was then placed into a plastic sample cup and analysed in the field by a portable X-ray fluorescence instrument ("pXRF") to provide analytical results. A total of 452 first pass soil samples were collected. Analytical results were relayed from the field and infill sampling was conducted in the areas of anomalous copper- in areas of anomalous copper -in-soil and a total of 232 infill samples were collected. The main copper-on-soil anomaly is approximately 1,800m long and 600m wide with a peak value of 422ppm and is broadly coincident with a surface geochemical anomaly defined by Mwinilunga Mines in the 1960s. A sub-set of soil samples will now be submitted for conventional laboratory based geochemical analysis as a QA/QC check on field results. Further follow up work is planned to follow up the significance of the soil geochemical anomaly to include trenching and/or drilling.
공시 • Jun 21Tertiary Minerals plc Announces Drilling Update, Konkola West Copper ProjectTertiary Minerals plc announced that the first hole at the Konkola West Copper Project, hole number KWDD001, was recently reported by KoBold Metals Company to be at a downhole depth of 1,341m and continuing in the hanging wall sequence above the target horizon. More recently, drilling progress has been a little slower than anticipated due to use of a new drill rig and variable ground conditions. Drilling will continue until the target horizon is reached. No further announcement will be made until this first hole is completed but planning for a second drill hole is already underway.
공시 • May 22Tertiary Minerals plc Provides the Drilling Update for the Konkola West Copper Project in ZambiaTertiary Minerals plc provided the drilling update for the Konkola West Copper Project in Zambia. The first hole at the Konkola West Copper Project, hole number KWDD001, being drilled as part of an earn-in agreement with a subsidiary of KoBold Metals Company ("KoBold") and local partner Mwashia Resources Ltd, was recently reported by KoBold to be at a depth of 1,023m down-hole and continuing. The target of this drillhole is the ore-shale which hosts the copper mineralisation at the Konkola-Lubambe copper mines and the nearby Mingomba deposit. KoBold has reported that a number of expected key marker horizons have been intersected in the hole that are consistently seen in the stratigraphy above the ore-shale in these deposits. Given the known lateral variations in the thickness of individual stratigraphic units in this area it is not yet possible to predict with any certainty the depth at which the ore-shale might be encountered, though the Company estimates that drilling of KWDD001 will continue until mid-June 2024 with assay results to follow after that. However, drilling could take longer, or be completed sooner, depending on the thickness of the stratigraphic units yet to be drilled, as well as drilling conditions.
공시 • May 10Tertiary Minerals plc Announces the Approval of the Environmental Project Brief for Its Mupala Copper ProjectTertiary Minerals plc announced the approval of the Environmental Project Brief ("EPB") for its Mupala Copper Project (32139-HQ-LEL or the "Licence") which now clears the way for the start of mineral exploration activities at Mupala. The Mupala Copper Project is located 12 km west of the Company's Mukai Project and adjacent to the Anglo American/Arc Minerals joint venture project where Anglo American has a right to earn a 70% interest through expenditure of $88.5 million. Located in the prospective Domes Region of northwest Zambia on the west side of the Kabompo Dome which is host to multiple producing copper and nickel mines including First Quantum Mineral's Sentinel mining complex which adjoins the Company's Mukai Project. Letter of Consent received from Sailunga Chiefdom during tribal engagement conducted in February 2024 and EPB approval now received from the Zambia Environmental Management Agency. Recently acquired historical data has identified multiple copper-in-soil anomalies within the Licence. Work programmes expected to commence next month and will include soil sampling across the Licence to verify the identified soil anomalies and assist with surface regolith mapping.

공시 • Oct 16Tertiary Minerals plc Announces New Soil Sampling Results - Mushima North, ZambiaFollowing the recent release of soil sampling results from the C1 target area at its Mushima North Copper Project in Zambia, Tertiary Minerals plc reported further positive portable X-Ray fluorescence ("pXRF") analytical results from targets A1 and A2. Key Points: Areas A1 & A2 are targets for traditional Copperbelt sediment-hosted mineralisation where known deposits in Zambia and the DRC range in size up to supergiant size (>25mt contained copper). 248 soil samples were initially collected on a 200m x 200m spaced grid at the A1 and A2 targets. A further 311 samples were taken as an infill of the A1 grid at 100m x100m spacing and at 50m spacing along three east-west lines. pXRF analytical results at target A1 have outlined a significant open-ended copper anomaly with soil samples above 80ppm covering an area of 3 km long by up to 1.5 km wide, peaking at 280ppm copper. A high-grade area within the A1 copper-in-soil anomaly with values above 200ppm and averaging 231ppm copper has dimensions of 400m x 150m. pXRF results at target A2 show very high copper values, up to 1,239ppm copper in organic-rich samples from the perimeter of a marsh (dambo). The copper in this hydromorphic anomaly is likely transported and may be linked to the source of the A1 copper-in-soil anomaly. A new copper prospect was discovered during field evaluation of a historic electromagnetic target to the west of target A1. Values up to 0.43% (4,300ppm) copper were returned from average pXRF analysis of surface rocks showing visible oxide copper mineralisation. The Mushima North Copper Project comprises Exploration Licence 27068-HQ-LEL. It covers 701 km2 and is located in Zambia's Northwest Province. Tertiary Minerals plc's 96% owned subsidiary, Tertiary Minerals (Zambia) Limited, is currently earning up to a 90% interest in the Project from local partner Mwashia Resources Limited. Mushima North is one of five projects in Zambia where Tertiary is exploring for copper and one of two projects which benefit from the Company's technical cooperation and data sharing agreement with leading copper producer First Quantum Minerals. The Project lies 20 km to the east of the Kalengwa copper mine (past production 4 million tons grading 5.2% Cu and 40 g/t Ag and pre-mining reserve of 600,000 tons grading 16% copper) believed to be one of the highest-grade copper deposits ever to be mined in Zambia. In the 1970s high grade ore in excess of 26% copper, making up approximately 20% of the orebody, was trucked for direct smelting at other mines in the Copperbelt. Kalengwa was discovered by drill testing a coincident copper-in-soil anomaly and gravity anomaly and has characteristics of the Iron-Oxide-Copper-Gold ("IOCG") class of deposits. FQM has provided Tertiary with an extensive exploration database for Mushima North which includes airborne magnetic and electromagnetic geophysical data, as well as 500m spaced reconnaissance soil sample analytical results. Additional historical data for the area was made available by JAW Consulting LLC of Golden, Colorado which was commissioned by the Company to compile historical data and provide a detailed interpretation and targeting report. The JAW targeting report has drawn on historical exploration from the 1970s onwards by Roan Consolidated Mines, African Minerals, Zamanglo Prospecting Ltd. and BHP Billiton. The latter was exploring for IOCG deposits (a class of mineral deposit that includes some of the largest in the world, including Olympic Dam in South Australia). BHP planned two holes to test for IOCG mineralisation at target C1 but terminated all exploration in Zambia in 2012 without drilling the planned holes. Further details of the targets generated by this report can be found in the Company's news release of 1 June 2023. Targets A1 and A2 were identified from wide spaced reconnaissance soil sampling carried out by FQM. In September 2023, the Company contracted Geo-Junction Consulting Limited to perform a soil sampling programme at Mushima North to cover the C1, A1 and A2 targets. Positive results from target C1 were released on 5 October 2023. This release details the pXRF analytical results from targets A1 and A2. A total of 184 samples were collected on or around target A1 with a sample spacing of 200m. Soil samples were collected from the B-horizon1, dried and sieved to -180 micron. The sieved soil samples were placed into a sample cup and analysed using a pXRF instrument. Based on preliminary field pXRF analysis infill sampling was then carried out on 100mx 100m spacing with three 400m spaced lines sampled at 50m spacing. pXRF results from target A1 indicate a broad northeast striking copper-in-soil anomaly which, at a 80ppm copper cut off, covers an area approximately 3km long by up to 1.5 km wide. Within this area soil samples average 148ppm and peak at 280ppm copper. The A1 soil anomaly has a high-grade core at its north end where all soil values are in excess of 200pppm copper over an area 400m x 150m and average 231ppm copper. pXRF results from target A2 show very high copper-in-soil values of up to 1,239ppm. However, the high values are confined to organic rich sediments at the edge of a dambo (an area of shallow wetland). It is most likely that copper in these sediments is a result of hydromorphic concentration of copper in groundwater sourced from a copper-rich area, possibly the sources of the A1 copper anomaly some 3km distant. The A1 and A2 copper-in-soil anomalies have a favorable structural setting for mineralisation and the A1 anomaly is a further high priority for follow up drilling. During the field work at targets A1 and A2, samples containing visible spotty copper minerals malachite and chrysocolla were found when field checking an area 2 km west of target A1 where an electrical conductor had been identified by a previous explorer in an area underlain by iron-rich conglomerates. These conglomerates stretch over a 6 km strike length and are coincident with a low-level gravity anomaly. Surface samples contained up to 0.43% copper (average of three pXRF readings per sample). Soil samples around this new occurrence were not anomalous but the new find warrants further follow-up mapping and sampling.
공시 • Oct 07Tertiary Minerals plc Announces First Soil Sampling Results from Mushima North Copper Project, ZambiaTertiary Minerals plc announced positive follow-up results from portable XRF ("pXRF") analysis of soil samples at the C1 target area at its Mushima North Copper Project in Zambia, one of a number of targets covered in a recent soil sampling campaign. Key Points: Target C1 is permissive for Iron-Oxide-Copper-Gold ("IOCG"1) style and traditional Copperbelt sediment-hosted mineralisation. Includes a lone 1970s drill hole, RKN800, which, in resampling by Tertiary, contains 33m grading 0.24% copper from 122m to the end of hole in association with highly anomalous arsenic. 572 soil samples collected on 200m x 200m grid have defined a significant open-ended copper anomaly above 60ppm over 4km x 1.25km, with peak value of 211ppm copper proximal to RKN800. The highest copper-in-soil values are coincident with highest arsenic values in pXRF soil results; consistent with strongly anomalous arsenic in hole RKN800. A subset of samples will now be submitted for laboratory-based check analysis. pXRF results from additional target areas A1 and A2 are awaited and expected shortly.
공시 • Sep 13Tertiary Minerals plc Announces Provisional Soil Sampling Results Mukai Copper Project, ZambiaTertiary Minerals plc announced that portable XRF analysis of soil samples has defined a substantial copper-in-soil anomaly at the Mukai Copper Project in Zambia. Key Points: A total of 526 samples were collected on a 300m x 100m grid infilled up to 100m x 50m and analysed in the field using a portable XRF instrument ("pXRF"). A large high-grade copper-in-soil anomaly is defined with values in excess of a 160ppm copper over an area of approximately 1,300m by 400m with a peak soil value of 1,660ppm copper (0.16%) and soil values averaging 252ppm (average of 63 samples). This high-grade anomaly is part of broader copper-in-soil anomaly defined by 162 samples containing greater than 80ppm copper and averaging 173ppm copper over an area of approximately 1,800m by 800m. Soil anomalies from past producing mines on the Copperbelt typically have thresholds in the range 50 to 150ppm copper, averaging 80ppm copper and peak values in the range 100-450ppm copper and averaging 210ppm copper. A subset of samples will now be submitted for laboratory-based check analysis. The option and earn-in periods at Mukai and Mushima North Projects have been extended by six months by agreement with local partner Mwashia Resources to account for earlier delays with forest permits. The Mukai Copper Project comprises Exploration Licence 27066-HQ-LEL which covers 55.4 km2 and is located 125km west of Solwezi in the north-western Province of Zambia. Tertiary Minerals plc's 96% owned subsidiary, Tertiary Minerals (Zambia) Limited, is currently earning up to a 90% interest from local partner Mwashia Resources Ltd. The Company has now agreed to extend the option-earn-in period by six months to account for delays experienced earlier this year in obtaining forest permits at Mukai and Mushima North. Geologically the Mukai Project is located in the Domes Region of the Central African Copperbelt and it encompasses Lower Roan Subgroup rocks which are part of the southern flank of the highly prospective Kabompo Dome. The project lies directly adjacent to First Quantum Minerals Limited's ("FQM") Trident Project licences which include the recently opened Enterprise nickel mine and the large producing Sentinel (Kalumbila) copper mine, located 8km south and 18km southeast of the Mukai licence, respectively. The Company has a data sharing and technical cooperation agreement with FQM for the Mukai and Mushima North Projects, further details of which are given in the RNS of 15 September 2022. The impetus for the soil sampling programme at Mukai was the interpretation of regional historical exploration results provided by FQM where copper-in-soil anomalies and significant drill intersections of copper occur in a stratigraphic package which extends into the licence area. The Company contracted Geo-Junction Consulting Limited to perform a soil sampling programme at Mukai with work commencing in late-August 2023. A total of 311 soil samples were collected in a first pass soil sampling programme on north-south sampling lines with a sample spacing of 100m and line spacing of 300m. Soil samples were collected from the B-horizon, dried and sieved to -180 micron. The sieved soil samples were placed into a sample cup and analysed using a pXRF instrument to guide infill sampling. Initial pXRF results were reviewed in the field and a total of 206 further samples were collected by infilling the first pass grid at 150m line spacing and an offset 100m sample spacing. In the areas of the most significant copper-in-soil anomalies the infill samples were collected on a much tighter 50m by 100m grid. As a guide to the significance of soil sampling results, the Company notes2 that B-horizon soil anomalies for freely drained soils in the vicinity of various ore zones at current and past producing mines on the Copperbelt have thresholds in the range 50 to 150ppm copper, averaging 80ppm copper and peak values in the range 100-450ppm copper and averaging 210ppm copper. In addition, published data3 for the giant Sentinel copper deposit (>1 billion tonnes grading 0.51% copper, located close the Company's Mukai Copper Project in northwest Zambia) shows that the median copper value for soil samples collected over the sub-cropping expression of the orebody was 120ppm and only one soil sample exceeded 500ppm copper. Initial pXRF results from the Mukai Copper Project indicate a broad northwest striking anomaly approximately 1,800m long and 800m wide comprising 174 soil samples with copper values in excess of 80ppm. Soil samples in this broad anomaly contain an average copper value of 164ppm. Within this, a higher-grade core strikes northwest, following the favourable stratigraphy, and has dimensions 1,300m long and 400m wide comprising 71 soil samples averaging 226ppm copper and having a peak value of 1,660ppm copper (0.16% copper). The Company will send a subset of samples for traditional laboratory-based analysis as a check on these pXRF results.
공시 • Aug 10Tertiary Minerals plc Provides Exploration UpdateFollowing the receipt of forest permits announced on 31 July 2023, Tertiary Minerals plc announced the start of soil sampling and to provide the following update on its Zambian copper exploration projects. Konkola West Project: Interpretation of airborne geophysical data provided by KoBold Metals has now identified areas in the north and northwest of the licence where the target Lower Roan formation - the main host to copper mineralisation on the Zambian Copperbelt - may be shallower and less steeply dipping than on the eastern side of the licence. Soil sampling is now underway to explore higher up in the sequence with approximately 260 soil samples due to be collected over the next few days. Soil samples will be analysed in the field using a portable XRF ("pXRF") analyser and follow up infill sampling will be carried out as appropriate. Konkola West lies immediately west of the Konkola-Lubambe-Musoshi copper mining licences and potentially contains downdip extensions of the laterally continuous Lower Roan ore shale horizon on the east side of the licence. Mukai Project: Soil sampling will commence at Mukai immediately after completion of work at Konkola West. Mukai adjoins First Quantum Minerals' ("FQM") Trident Project licences which include the large Sentinel copper mine and the recently opened Enterprise nickel mine. Approximately 310 soil samples will be collected on a 300m x 100m grid with additional infill sampling to test a historic soil anomaly in favourable stratigraphy along strike of FQM's Tirosa Prospect where FQM has drilled up to its licence boundary with Mukai. Mushima North Project: Mushima North is located east of the high grade Kalengwa Copper Mine and numerous targets have been identified for both iron-oxide-copper-gold ("IOCG") mineralisation and conventional Copperbelt style mineralisation. Soil sampling at Mushima North is currently scheduled to follow on from that at Mukai. Approximately 1,150 samples will be collected on 200 x 200m grids in three main target areas. Lubuila Project: Further to the announcement of 17 May 2023 the Company has now completed check analysis of soil samples collected earlier in the field season at Lubuila as well as an evaluation of multi-element geochemistry.Copper results have confirmed the previously reported anomalous copper results from Area C. However, the interpretation of multi-element analytical results suggests that the anomalous results are likely the result of lateritic enrichment rather than indicative of significant in-situ copper mineralisation.
공시 • Jun 07Tertiary Minerals plc Provides Exploration UpdateTertiary Minerals plc announced that, via its local partner, Mwashia Resources, it has been provided with extensive geophysical exploration data for its Konkola West copper exploration project in Zambia by KoBold Metals. KoBold Metals, whose shareholders include Breakthrough Energy Ventures, a climate and technology fund founded by Microsoft's Bill Gates, and backed by Amazon's Jeff Bezos and Virgin's Sir Richard Branson, and mining giant BHP, is investing USD 150 million into the evaluation of the Mingomba Copper Deposit (Lubambe Extension Project) on the mining licence adjoining the Company's Konkola West exploration licence. The data now provided comprises airborne gravity, magnetic and radiometric data for the entire 72 sq.km. licence area and was collected by KoBold in 2021. This data set was collected as part of a wider regional airborne geophysical survey incorporating Konkola West and targeting down-dip and along-strike extensions of the contiguous Musoshi-Lubambe-Mingomba-Konkola copper deposits which host the Musoshi Mine in the Democratic Republic of the Congo and the Lubambe and Konkola mines in Zambia. Together these deposits define a continuous zone of mineralisation over 15km long with a pre-mining endowment of over 775 million tons grading 2-3% copper. Konkola West is located approximately 2,000 metres southwest of the Mingomba deposit which currently has a resource of 250 million tonnes with a mean grade of 3.8% copper.
공시 • Jun 01Tertiary Minerals plc Releases Separate Project Focus Presentation for Its Mushima North Project in ZambiaTertiary Minerals plc announced that further to the Company's announcement of 28 April 2023, advising of favourable copper analytical results from sampling of core from historic drill hole RKN800, the Company is now releasing a separate "Project Focus" presentation for its Mushima North Project in Zambia. Mushima North is one of five projects in Zambia where Tertiary is exploring for copper, and one of two projects which benefit from the technical cooperation and data sharing agreement with leading copper producer First Quantum Minerals ("FQM"). The Project lies to the east of the high grade Kalengwa mine (past production 4 million tons grading 5.2% Cu and 40 g/t Ag and pre-mining reserve of 600,000 tons grading 16% copper) which was discovered by drill testing a coincident copper soil anomaly and gravity anomaly. FQM has provided its extensive database for Mushima North which includes airborne magnetic, electromagnetic and radiometric geophysical data as well as 500m spaced reconnaissance soil sample analytical results. Additional historical data for the area was made available by JAW Consulting LLC ("JAW") of Golden, Colorado which was commissioned by the Company to compile historical data and provide a detailed interpretation and targeting report. The JAW targeting report has drawn on historical exploration from the 1970s onwards by Roan Consolidated Mines, African Minerals, Zamanglo Prospecting Ltd. and BHP Billiton. The latter was exploring for iron-oxide-copper-gold ("IOCG") deposits, a class of mineral deposit that includes some of the largest in the world, including Olympic Dam in South Australia. The two highest priority targets are: O Target C1 - A prominent gravity high defined by BHP Billiton's Falcon airborne gravity survey with a coincident copper soil anomaly. The wide, low-grade, intersection of copper mineralisation recently announced from resampling core from drill hole RKN800 sits on the margin of the gravity anomaly making this an exciting target for follow up. Drill hole RKN800 pre-dates BHP Billiton's gravity survey. The C1 gravity anomaly was designated as an IOCG drill target by BHP Billiton, but never tested. Target A1 -A 1.7km long copper soil anomaly with values up to 350ppm copper (in portable x-ray fluorescence analysis) defined by 500m spaced samples and supported by coincident arsenic and zinc anomalies. This is a target for more conventional Copperbelt style mineralisation.
공시 • May 18Tertiary Minerals plc Announces the Completion of Its Recently Announced Soil Sampling Programme At the Lubuila Copper ProjectTertiary Minerals plc announced the completion of its recently announced soil sampling programme at the Lubuila Copper Project. Highlights - Lubuila Copper Project: Planned soil sampling programme completed inclusive of additional follow-up sampling based on in-field portable X-Ray Fluorescence (pXRF1) analytical results. 425 soil samples collected across three separate grids targeting two untested areas of interpreted Lower Roan Group sediments (Areas A and B) and a historical copper-in-soil anomaly at Area C in Upper Roan Group sediments. Preliminary results indicate a large open-ended copper-in-soil anomaly defined over an area of approximately 1,000m x 680m at Area C with a peak copper value of 306 ppm and an average value of 125ppm Cu. Sample subset to be sent for traditional wet geochemical ICP analysis for data validation and interpretation.
공시 • Jan 18Tertiary Minerals plc Announces Laboratory Check Analytical Results on Soil Samples from the Jacks Copper Project in ZambiaTertiary Minerals plc announced that laboratory check analytical results on soil samples from the Jacks Copper Project in Zambia have confirmed and enhanced the provisional results previously reported based on portable XRF analyses taken in the field. Key Points: Laboratory check multielement analytical results now received for 107 soil samples from 4 sample grids. Laboratory results show excellent correlation with previously reported field pXRF results. New scandium analyses (not available with pXRF analysis) allows evaluation of key copper:scandium ratios. High Cu:Sc ratios are considered indicative of hydrothermal copper sulphide mineralisation elsewhere in Zambia. The high Cu:Sc ratios obtained from the soil samples taken over copper sulphide mineralisation intersected in Company's 2022 drill programme at Area D validate the application of the Cu:Sc ratio and both enhance and extend the Area D soil anomaly beyond the area drilled. Laboratory analyses for 27 contiguous soil samples along a check profile in Area C exhibit high Cu:Sc ratios for a strike length of approximately 1 km and make Area C another priority for drill testing.
