Talisker Receives Assay Results from 1105 Level Lateral Development at the Mustang Mine

Press Release

TORONTO, July 24, 2025 — Talisker Resources Ltd. (“ Talisker ” or the “ Company ”) (TSX: TSK, OTCQX: TSKFF) is pleased to announce that the Company has received assay results from underground face sampling of lateral development from the 1105 level at the Mustang Mine. Lateral development is mining conducted along the vein to allow for equipment access required for later stope extraction between levels. This development is conducted at approximately 3 X 3 metre dimensions, larger than the 1.8 metre width of the actual mining stopes. The 1105 level is located 1,105 metres above mean sea level and represents one of the upper most levels of the Mustang Mine. Sampling on this level was conducted to support future stopes identified on the Alhambra, BK and BK9870 veins. Sampling is conducted by cutting a linear horizontal channel approximately 10 centimeters wide across the width of the development face.

Key Highlights:

551 g/t over 0.63m within 118.9 g/t over 3.02m from BK9870 Vein, West Face No. 1 (sample X002316)
196 g/t over 0.44m within 23.7 g/t over 3.78m from BK9870 Vein, West Face No. 2 (sample X002261)
92.7 g/t over 0.47m within 17.1 g/t over 2.74m from BK Vein, West Face No. 2 (sample X002311)
68.6 g/t over 0.47m within 10.3 g/t over 3.33m from Alhambra Vein, West Face No. 3 (sample X000383)
65.1 g/t over 0.47m within 21.3 g/t over 2.96m from Alhambra Vein, East Face No. 1 (sample X000338)
56.8 g/t over 0.92m within 15.4 g/t over 3.8m from BK9870 Vein, West Face No. 3 (sample X002326)
52.7 g/t over 0.58m within 10.1 g/t over 4.17m from Alhambra Vein, West Face No. 15 (sample X000805)
40.9 g/t over 0.7m within 10.6 g/t over 3.34m from Alhambra Vein, East Face No. 3 (sample X000416)
40.1 g/t over 0.73m within 8 g/t over 4.29m from Alhambra Vein, East Face No. 4 (sample X000432)
28.1 g/t over 0.86m within 7.8 g/t over 3.43m from Alhambra Vein, East Face No. 2 (sample X000404)

Terry Harbort, CEO of Talisker stated, “These outstanding results from the 1105 level face sampling reinforce the high-grade nature of Bralorne and its position as one of the world’s highest grade gold deposits. Even diluted to development widths of 3 metres, which is well beyond our mining width of 1.8 metres we see strong confirmation of the consistent grade with abundant occurrences of visible gold (shown in the face photos below in green). Shareholders will also note, the close correlation between our modelled veins displayed by the blue and red lines and the actual vein position. An excellent outcome for our dedicated resource modelling team!”

Talisker is actively milling run of mine gold bearing development material at Nicola Mining’s Merrit mill facility. To date, a total of 2,143 tonnes of material has been milled producing approximately 12 kilograms of gravity concentrate and 40 tonnes of sulphide concentrate. A further 2,200 tonnes of material has been delivered to the mill and is awaiting milling. The first sale and shipment of concentrate material is expected at the end of this month. Talisker is continuing to deliver new run of mine material daily at a rate of approximately 150 tpd.
