Arc Minerals Limited Publishes Geophysical Survey Results For Virgo Project In Botswana Arc Minerals Limited published the results of its geophysical programme over the licence PL135/2017 of the Virgo project, inside the Zone 5 corridor of the Kalahari Copper Belt in the Republic of Botswana. IP survey extends significantly the inferred contact between the D'Kar Formation and Ngwako Pan Formation within the licence to 18 kilometres. Several high-priority anomalies identified with strong Induced Polarisation chargeability/resistivity anomalies and areas of structural complexity creating favourable potential mineral trap sites. Final selection of drilling contractor imminent. Drilling activities expected to commence in early August. 3D Earth Exploration (Pty) Ltd. was contracted to conduct a ground magnetic and IP survey over the PL135/2017 licence, as a continuation from the 2024 IP survey. The programme commenced with a ground magnetic survey and was dominated by a large magnetic feature in the east that corresponds to known Kgwebe volcanics that heavily affected the magnetic signature. After completing 230 line km, it was decided that the focus of the programme should remain on the IP survey, which had strongly identified the prospective DKF-NPF contact in the 2024 IP campaign. The magnetic survey did pick up an area of structural complexity on the southern end of the Mawana Fold, which was further confirmed by the IP survey. This is now becoming an area of interest as it could potentially host mineral trap sites conducive to the formation of larger deposits. The IP survey consisted of a total of 59 line km, made up of 51 line km of Gradient IP and 8 line km of Insight Section IP. The survey employed a Walcer TX KW10 transmitter and an Iris Elrec Terra IP receiver. For both Gradient Array and Insight Section IP, a 25m dipole was used during measurements with a reading cycling time of 20 to optimize data quality by increasing signal to noise ratio. The survey lines were designed to cover the full extent of the inferred DKF-NPF contact across the licence and interpreted redox boundary. The IP survey appears to have extended the interpreted redox boundary (DKF-NPF Contact) by a further 14 kilometres to the east of the area surveyed in 2024, bringing the total contact length in the licence to 18 kilometres. The D'Kar Formation is typically characterised by high apparent chargeability and low apparent resistivity and occupies the southern side of the interpreted redox contact, whilst the northern side of the contact is assumed to be the Ngwako Pan Formation. A redox contact jog has been noted in the central part to the area surveyed and could also be an area to target for economic mineralization. The IP survey employed a Walcer TX KW10 transmitter and an Iris Elrec Terra IP receiver. The survey lines were designed to cover the full extent of the inferred D'Kar and Ngwako Pan contact across the licence and interpreted redox boundary. For Gradient Array the current electrode spacing AB was 2,000m on all surveys for a depth of investigation estimated at 400m (20% of AB). C1 was at station 0 and C2 at 2,000N or 1,000N and 3,000N, to cover the southern and northern 1,000m portions of the 2,000m traverse lines. The Insight Section IP survey consists of a number of readings at a given station at different current electrode separation representing different depths of investigation. The depth of each reading is 20% the current electrode spacing AB. Therefore, for depth levels from 50m to 400m at 50m intervals measured in this survey, the A-B separation was 250m to 2,000m at 250m intervals, respectively. The depth levels surveyed were at 50m intervals from 50m to 400m for all surveyed lines, corresponding to ABs from 250m to 2,000m. For both Gradient Array and Insight Section IP, a 25m dipole was used during measurements with a reading cycling time of 20 to optimize data quality by increasing signal to noise ratio. Data was downloaded daily on return to the camp in the evening and processed using Geosoft's Oasis Montaj. The following field processing was done: Download data for the survey line to date (from start to current day) into a laptop. The data was edited and XY coordinates in WGS84, Zone 34S inserted manually. Data was imported into a Geosoft database and gridded to produce chargeability and resistivity images which are then contoured. For Gradient Array data the grid cell size used is 125m (1/4 of 500m line spacing). For Insight Section IP, a cell size of 12.5m was used (1/4 of 50m depth layer separation). The Senior Geophysicist also gridded and QC'd the data on site daily before sharing with Alvis. The ground preparation for the following day was also adjusted according to the current output achieved on the day. For both the magnetic and Induced polarisation survey the interpretation remains qualitative and subject to geological validation through follow-up drilling. Magnetic, chargeable and resistive features identified from these surveys are considered exploration targets only and require follow-up geological and drilling validation. Tillkännagivande • Mar 11
Arc Minerals Limited Commences Geophysical Work Programme in Botswana Arc Minerals Limited announced the commencement of a ground-based magnetic survey and an Induced Polarisation survey over its PL135/2017 licence at the Virgo Project, located within the Central Structural Corridor of the Kalahari Copper Belt in the Republic of Botswana. Magnetic and Induced Polarisation surveys are designed to define the contact between the D'kar and Ngwako Pan formations. Field camp preparation commenced and teams mobilised to carry out these surveys. 295 line kilometers of ground-based magnetic surveying to start this week. 52.5 kilometers of Induced Polarisation surveying to follow immediately thereafter. Data acquisition and interpretation expected to be completed by the end of Second Quarter. The programme builds directly on the successful limited Induced Polarisation survey conducted over part of the PL135/2017 license in 2024, where the contact between the D'kar and Ngwako Pan formations were accurately identified and verified by the survey, before focused drilling commenced. The Company has decided to extend the Induced Polarisation survey to cover the full length of the hypothesized contact zone in its license area, and will be further complemented by a ground-based magnetic survey over the same length. All the known copper deposits and occurrences in the Kalahari Copper Belt occur at, or immediately above the D'kar and Ngwako Pan formations contact, particularly where structural domes create favourable settings for copper and silver mineralisation. The Company has contracted a Botswana-based geophysical company to carry out the surveys. A field camp has been established and will cater for over 50 people at peak activity, with the magnetic survey commencing this week. The planned ground-based magnetic survey consists of 295 line kilometers at a 50 meter line spacing, with readings taken every 5 meters. The magnetic survey will provide additional granularity around the structures coming into and around the dome and along the limbs, significantly refining the Company's geological model and overall understanding. The ground-based Gradient Array Induced Polarisation survey over the contact zone and its extents will assist in accurately identifying the location of the D'kar and Ngwako Pan formations contact and provide an efficient, cost-effective and high-resolution map of the sub-surface chargeability and resistivity, discriminating between types of conductive structures and providing targets for drilling. A total of 52.5 line kilometers are planned to be surveyed, comprising 42.5 kilometers of Gradient Induced Polarisation and 10 kilometers of insight Section Induced Polarisation. The survey employs a pole-dipole array with 25 meter electrode spacing. Tillkännagivande • Jul 31

Arc Minerals Ltd Announces Assay Results Extends Copper Mineralisation Arc Minerals provided an update on exploration activities at its Joint Venture with a subsidiary of Anglo American in Zambia. Highlights: Diamond Drill Hole KCDD002 - 40.60m @ 0.61% Cu from 22.25m: Incl. 7.70m @ 1.72% Cu from 26.75m, or 12.75m @ 1.20% Cu from 22.25m. Mineralisation confirmed 1.5km from Cheyeza East Oxide Occurrence. Both Oxide and Sulphide Mineralisation Intersected. Six holes completed for a total of 4,016m drilled at four targets. Deepest hole drilled down to 977.40m. Sulphide Mineralisation confirmed at Nkwazhi. Following an extensive geological mapping and rock chip and soil sampling program over the Anglo JV license areas, a diamond drilling campaign commenced in August 2024 with six drill holes completed for 4016 m. Assay results have now been received for three of the six holes. Near surface mineralisation observed at a new target approximately one and a half kilometres east of the existing oxide occurrence at Cheyeza has been verified by diamond drilling. Assay data from hole KCDD002 includes 40.60m at 0.61% Cu from 22.25m down the hole, including 12.75m @ 1.20% Cu from 22.25m and 7.70m @ 1.72% Cu from 26.75m. The KCDD002 assay results demonstrate the potential to add to the known extents of the oxide occurrences at Cheyeza, where similar high grade zones have been intersected and reported in the past. Historic hole CHDDE004 intersected 18m @ 2.35% Cu from 30.60m with a higher grade zone of 7.60m @ 4.15% Cu from 39m, and hole CHDDE060 intersected 39m @ 1.47% Cu with a higher grade zone of 10m @ 2.25% Cu from 41m. Importantly and unlike the previously reported oxide occurrence which is characterised as being a remobilised copper oxide occurrence, the oxide mineralisation intersected in hole KCDD002 may be the result of weathering of sulphide mineralisation at source, which is supported by the presence of sulphide mineralisation below the oxide zone. Assay results have also been received for the two holes drilled at the new target Nkwazhi, where low grade sulphide mineralisation was confirmed in the first hole. Tillkännagivande • Nov 14
Arc Minerals Limited Announces Results from Drilling Programme at Kalahari Copper Belt in the Republic of Botswana Arc Minerals announced results from the recently completed drilling programme at its PL135/2017 license that forms part of its Virgo Project within the highly prospective Central Structural Corridor of the Kalahari Copper Belt in the Republic of Botswana. Highlights: First phase drill programme completed with a total of 3,000m drilled. Copper-Silver Mineralisa on Intersected. Diamond drill hole ALV-DD-004 - 3m @ 1.29% CuEq within a broader 6m @ 0.82% CuEq. Geological, Stra graphic and Structural se ng similar to MMG's Zone 5. The initial aim for the first phase drill campaign was to test for extensions of the mineralisation intersected by MMG in their adjacent license, where 4.3m @ 1.65% CuEq and 6.10m @ 2.56% CuEq were reported in holes HA- 1393-D and HA-1394-D. The Company completed eight holes for 3,000m drilled with diamond drill hole ALV-DD-004 intersecting 3m @1.29% CuEq within a broader6m @ 0.82% CuEq. Six of the remaining seven holes drilled intersected elevated to anomalous copper mineralisation with ini al observations of the core displaying similar geological, graphic and structural settings to that of MMG's opera ng Zone 5 underground mine. Further review of the assay data and drill core suggests that the first phase drill programme intersected mineralisation laterally on the fringe of the copper zone, in the iron rich zone, the interpreted outer halo of the main mineralised zone. All the data is currently being assessed and planning put in place for a second phase drill programme, that will vector away from the iron rich zone, targeting the interpreted inner copper sulphide zone. background on the Virgo Licences Licence PL 135/2017. The Company's prospecting licence PL135/2017 is surrounded on three sides by the prospecting licences of Khoemacau Copper Mining Limited, who have recently been acquired by MMG for c.$1.9 billion. This licence is located towards the south-eastern margin of the Kalahari Copper Belt occupying a similar geological se ng to that recently drilled by Khoemacau at their recent Mawana Fold Discovery and the Zone 9 exploration target, where economic grades of copper mineralisation have already been intersected by drilling. These discoveries are located at the north-western and south-eastern margins of the Company's prospecting licence, respectively. Khoemacau's Mawana fold discovery has defined a possible economic zone of copper mineralisa on that appears to trend towards and into the Company's licence PL 135/2017. The Company's recent scout drill holes intersected anomalous grades of copper mineralisation close to this apparent trend and confirmed an east-west trendingDKF-NPFcontact posi on approximately 5km long running through the licence. In November 2021, Arc Minerals Limited acquired a 75% interest in Alvis-Crest (Proprietary) Limited, the holder of two prospec ng licences (PL 135/2017 & PL 162/2017) in Botswana's Kalahari Copper Belt, colloquially called the Virgo Project/Licences. Licence PL 135/2017 is approximately 10km south-east of the large underground Khoemacau Copper mine recently commissioned by Cupric Canyon Capital LP. The Virgo Licences cover an area of over 210km2 and lie within (PL 165/2017) and adjacent (PL 135/2017) to the highly prospec ve Central Structural Corridor and within 10km and 50km of the Zone 5 and Banana Zone copper projects respecively, known as the two largest copper projects on the KCB. Historically, two copper-nickel soil anomalies have already been recorded on PL 135/2017 and PL 162/2017 and are approximately 3km and 2.5km in strike length, respectively. The largest of the two anomalies, located on PL 135/2017, overlays an interpreted DKF-NPF contact, while a second, more intermitent, anomaly may be linked to extensional faulting around the dome edge. The large coherent anomaly on PL 162/2017 also appears to overlay the interpreted DKF-NPF contact on the northern limb of a syncline. Tillkännagivande • Nov 13

Arc Minerals Ltd Provides an Update on Exploration Activities At Its Joint Venture with A Subsidiary of Anglo American in Zambia Arc Minerals Ltd. provided an update on exploration activities at its Joint Venture with a subsidiary of Anglo American in Zambia. Drilling commenced this year at the first new target approximately 1km east of the oxide occurrence at Cheyeza. The first hole targeted a Cu-Ni anomaly generated by the latest soil sampling programme. Anomalous copper mineralisation over a downhole thickness of around 45m was observed in the saprolite zone. Pending results from the laboratory, this hole demonstrates the potential to significantly expand the known oxide mineralisation at Cheyeza. Two holes were drilled at the new target Nkwazhi that is located between Cheyeza and Muswema, testing a thickened Lower Roan unit in this part of the basin. The first hole intersected copper mineralisation of over 20m at the base of the Upper Roan along with anomalous nickel in a marker talc-schist unit in the Lower Roan, below which currently no further mineralisation has been observed. The second hole drilled 400m away did not intersect mineralisation. The third target tested is located approximately 4km to the south-east of Muswema where a second order soil geochemical anomaly is present. Initial observations from this first hole are encouraging with lithologies and alteration styles akin to known deposits within the Domes Region of the Copperbelt being intersected. Copper mineralisation is also observed in parts of the drill core with multiple generations of chalcopyrite observed. This target is being prioritized for follow-up drilling. During the campaign, an extensive soil sampling programme was completed along traverses and focussed on the basin margin and in particular the Lower Roan.Over 12,000 samples were collected and analysed with the principal aim being to better understand the architecture of the Roan stratigraphy, source rocks and vectors to potential reductants. The information garnered from this soil sampling program, integrated with historical data has resulted in a more robust surface geological map for the basin and has supported the current drill targeting.
