Talisker Reports Mustang Underground Face Sample Results Including 886 g/t over 0.51m within 254.5 g/t over 2.74m on 1060 Level and Defines a 60 metre Strike Length High-grade Shoot Averaging 27 g/t on the 1045 Level

Press Release

TORONTO, April 15, 2026  — Talisker Resources Ltd. (“Talisker” or the “Company”) (TSX: TSK, OTCQB: TSKFF) is pleased to report the development on the newly established 1045 Level along the BK Vein at the Mustang Mine where the Company has successfully intersected a continuous 60-metre strike length of high-grade mineralization. The zone comprises a well-defined banded quartz vein averaging 27 grams per tonne (g/t) gold across an average width of 0.85 metres with a total of 384 visible gold occurrences across 17 of the 25 faces channeled on the structure. This result highlights the strong continuity of the mineralized structures within the Mustang Mine and further supports Talisker’s geological model. Ongoing development continues to demonstrate the robustness and expansion potential of the BK Vein system, reinforcing confidence in the asset’s ability to deliver consistent high-grade material.

Additionally, Talisker is pleased to report that new development along the BK Vein on the 1060 Level at the Mustang Mine has intersected a high-grade ore shoot, located approximately 15 metres beyond previously developed workings. This discovery underscores the significant upside potential for continued resource expansion at depth and along strike within the BK Vein system.

Key Highlights:

• 866 g/t over 0.51 m within 254.52 g/t over 2.74 m from BK Vein, West Face No. 11
• 413 g/t over 0.38 m within 130.28 g/t over 1.30 m from BK Vein, East Face No. 26
• 380 g/t over 0.35 m within 75.44 g/t over 1.88 m from BK Vein, East Face No. 2
• 234 g/t over 0.57 m within 102.33 g/t over 1.32 m from BK Vein, East Face No. 28
• 142 g/t over 0.40 m within 41.03 g/t over 1.44 m with from BK Vein, East Face No. 4
• 89.8 g/t over 0.49 m within 33.62 g/t over 1.43 m from BK Vein, East Face No. 23
• 80.3 g/t over 0.47 m within 24.40 g/t over 1.63 m from BK Vein, East Face No. 18
• 66.9 g/t over 0.45 m within 19.53 g/t over 1.84 m from BK Vein, East Face No. 5
• 32.3 g/t over 0.67 m within 17.65 g/t over 1.33 m from BK Vein, East Face No. 25
• 26.9 g/t over 0.88 m within 12.51 g/t over 2.17 m from BK Vein, West Face No. 10
• 14.6 g/t over 0.48 m within 6.03 g/t over 1.31 m from BK Vein, West Face No. 9

Terry Harbort, CEO of Talisker commented, “These new face sample results from the 1060 level and the new development on the 1045 level strongly support our upcoming stope extraction from these levels. With ramp and waste development also nearing completion on the 1030 level, we look forward to following these shoots further at depth.”
