Talisman Metals PLC Announces Significant Channel Sample Results At Tirzzit Copper-Silver Project Talisman Metals PLC announced the results from recent channel sampling activities completed at the Tirzzit copper-silver project in April 2026. Highlight sample results include: Channel TZ-CH001: 2.65m@1.71% Cu and 22.25ppm Ag - ended in mineralisation. Channel TZ-CH003: 0.94m@1.11% Cu and 6.00ppm Ag. Channel TZ-CH005: 1.63m@1.06% Cu and 4.25ppm Ag. Assay Results: Malachite mineralisation at surface within the Basal Series was channel sampled along strike over approximately 700m of the interpreted 4.6km trend, with approximately one channel sample collected every 100m. Along the 700m strike length the average intercept is 1.25m thick with grade of 1.21% Cu and 12.25ppm Ag (weighted average) and the alteration halo is about 2.00m thick on average. Intercepts usually sit on the top of the Basal Series and the hanging wall coincides with the contact on dolomite material. Results confirm that the mineralised horizon in the Basal Series identified during historical mapping shows lateral continuity, with values above cut-off grade (Cu Cut-Off Grade=0.3%) in all seven of seven channels over a strike length of 700m with copper (Cu) grades ranging from 0.75% to 1.74% and silver (Ag) grades ranging from 3 to 22ppm. Note that all the intervals are reported as true width. The sampling was done using channel sampling, with sub-vertical groves against outcrops dipping 30 Degrees to the North-North-West, cut with a circular saw on 63.5mm wide grove (HQ Core Diameter). True thickness of the sampling intervals were measured with a Jacob Staff. A total of 6 QA/QC samples were inserted into the original samples, comprising approximately 5% blanks, 5% field duplicates, and 5% certified reference materials. Samples were submitted to the ONHYM laboratory for sample preparation (crushing at 3mm, 85% pass and pulverised at 75microns) and multi-element analysis using a three-acid digestion (HCl-HNO3-HF) with ICP-AES finish. The analytical method has a lower detection limit of 5 ppm for copper (Cu) and 1 ppm for silver (Ag). Blank samples showed no evidence of contamination above three times the detection limit for Cu or Ag. Field duplicates demonstrated an acceptable repeatability, with an R² value of 0.93. Certified reference materials consistently returned copper values approximately 14% below certified values, and the Company is reviewing the potential analytical bias; however, the Company does not currently consider this issue to materially impact the interpretation of the results. For the reporting of each intercept stated comprised of more than one sample and samples are of differing lengths. In this case the average grade for the full interval length was calculated by length-weighted averaging, a standard method for determining average grades. The Tirzzit Project is a sediment-hosted stratiform Cu-Ag system, located 225km east of the city of Agadir, Morocco. The acquisition transaction of the Project was announced February 16, 2026 from a wholly owned subsidiary of Aya Silver & Gold Inc. (TSX: AYA; OTCQX: AYASF), the Company's 4.7% shareholder.

Talisman Metals plc Reports Positive Stream Sediment Sampling Results At Fougnar Project Talisman Metals PLC reported the results of its recently completed stream sediment sampling program at the Company's Fougnar licenses, which are 25km west of the Tizert copper-silver mine. The stream sediment work, in combination with historical field work and mapping, confirms the priority of established drill targets. Additionally, a previously unknown area of potential mineralisation has been discovered and will be added to the anticipated drill program scheduled for the summer 2026. Talisman believes that the sediment rock formations at Fougnar have excellent potential to host a large sediment-hosted copper-silver deposit, similar to other such deposits in the Anti-Atlas area of central Morocco. The main work focus at the Fougnar Project to date has been on the northern section, due to outcropping mineralisation. However, significantly copper-anomalous samples were collected on the southern part of the Fougnar Project over a 1km long interval. A total of 132 stream sediment samples were collected across the Fougnar Project. Multiple anomalous catchments were identified, with assay results of up to: 200 ppm Cu (Copper), 6,510 ppm Ba (Barium), 502 ppm Pb (Lead), 161 ppm Zn (Zinc). Newly identified target corridors extend over approximately 4 km across six distinct target areas, in addition to the existing 2.5 km mineralised trend identified along strike. Historical trenching areas containing known mineralisation were successfully confirmed by stream sediment sampling and used as orientation areas to establish threshold values for copper geochemical anomalies. Several geochemical anomalies are spatially associated with mapped structural features identified in the field and interpreted from ground TEM surveys and favourable lithological units within the basal series stratigraphy. Stream sediment samples were collected from fine sediment traps within active drainage channels over intervals of approximately 20-30 m along stream courses, while avoiding areas affected by anthropogenic contamination or stream disturbance. Sample locations were recorded using handheld GPS devices. Samples were dried and sieved to <63 µm prior to analysis. A total of 23 QA/QC samples were inserted into the sample stream, comprising approximately 5% blanks, 5% field duplicates, and 5% certified reference materials. Samples were submitted to the ONHYM laboratory in Rabat, Morocco for multi-element analysis using a three-acid digestion (HCl-HNO3-HF) with ICP-AES finish. The analytical method has a lower detection limit of 5 ppm for copper (Cu) and 1 ppm for silver (Ag). Blank samples showed no evidence of contamination above three times the detection limit for Cu or Ag. Field duplicates demonstrated excellent repeatability, with an R² value of 0.99. Certified reference materials consistently returned copper values approximately 10-20% below certified values, and the Company is reviewing the potential analytical bias; however, the Company does not currently consider this issue to materially impact the interpretation of the results. Follow-up work programmes underway including: Detailed geological mapping and rock-chip sampling; Trenching across priority target areas; Follow-up drilling of any significant trench results to test mineralisation at depth and along strike.

Talisman Metals plc Provides Update on Tirzzit Project Sampling and Exploration Results Talisman Metals PLC reported it has collected 7 channel samples at the Tirzzit Project, for a total length of 23m and 38 Trench samples including 5 QAQC samples and 3 Grab samples which have been sent for assaying. The first phase of fieldwork at Tirzzit consists of testing the grade and thickness of mineralisation along strike, from west to east, on outcrop in order to confirm: lateral continuity; historical Copper (Cu) and Silver (Ag) grades; and the location of thicker intervals for channel sampling at approximately 100m spacing, using a Jacob staff to determine true thickness and improve understanding of the controls on mineralisation. The initial 700m of strike targeted a horizon 1 to 5m thick from surface, exhibiting malachite mineralisation at surface amongst the 4.6 kilometres mineralized horizons that has been historically identified. The next phases of sampling will include: continuing channel sampling of the basal series from west to east, from Licence LE393478 to LE393507; channel sampling of the basal series within historical adits developed by the BRPM; conducting mapping of the lower limestone units to identify gossans, followed by grab sampling-initially above historically successful drill holes and subsequently across untested areas; and infill sampling of historical stream sediment coverage within previously untested watersheds. The preparation of a drill programme to redrill historical short holes that have missed mineralisation and drill out open extensions of mineralisation. The Tirzzit Project is a sediment-hosted stratiform Cu-Ag system, located 225km east of the city of Agadir, Morocco.
