Talisker Resources Ltd. Reports Mustang Underground Face Sample Results and Defines a 127 Metre Strike Length High-Grade Shoot Averaging 22 G/T on the 1045 Level Including 610 G/T over 0.51 of a Metre
Talisker Resources Ltd. reported continued success from underground development on the 1045 Level at the Mustang Mine, where the Company has successfully developed on a continuous 127-metre strike length of high-grade gold mineralization along the BK-9870 Vein. The zone comprises a well-defined banded quartz vein averaging 21.52 grams per tonne (g/t) gold across an average true width of 0.83 metres. These results provide further validation of Talisker's geological model, demonstrating increasing grade and improved continuity of mineralized structures with depth within the Mustang Mine at the Bralorne Gold Project, British Columbia, Canada. Key Highlights: 610 g/t over 0.58 m within 297.40 g/t over 1.21 m from BK-9870 Vein, East Face No. 26; 439 g/t over 0.44 m within 110.96 g/t over 2.29 m from BK-9870 Vein, East Face No. 24; 170 g/t over 0.89 m within 97.99 g/t over 1.62 m from BK-9870 Vein, East Face No. 25; 123 g/t over 0.53 m within 37.16 g/t over 1.83 m from BK-9870 Vein, West Face No. 12; 89.3 g/t over 0.49 m within 38.52 g/t over 1.17 m from BK-9870 Vein, East Face No. 4; 83.8 g/t over 0.48 m within 18.99 g/t over 2.85 m from BK-9870 Vein, West Face No. 2; 82.5 g/t over 0.50 m within 32.21 g/t over 1.32 m from BK-9870 Vein, West Face No. 18; 49.5 g/t over 0.58 m within 26.18 g/t over 1.10 m from BK-9870 Vein, East Face No. 11; 28.7 g/t over 1.34 m within 19.99 g/t over 3.17 m from BK-9870 Vein, West Face No. 7.

Channel sampling of underground ore headings at the Bralorne Gold Project was historically conducted by geologists using a rock saw to cut a horizontal 5 cm × 5 cm × up to 3.0 m groove across the entire face of the drift at a height of approximately 1.2 m above the sill. Following a robust statistical analysis comparing channel and chip sampling methods, Talisker transitioned to chip sampling, having demonstrated that the two methods produce statistically comparable results while improving operational efficiency and reducing sampling time. Under the current protocol, individual chip samples range from 0.35 m to 1.50 m in length and are selected to best represent identified geological structures, sulphide mineralization, or hydrothermal alteration suspected to bracket gold concentrations. Where vein or mineralized zones are wide, consecutive samples are collected across the structure to preserve geological resolution. Lithological breaks are avoided within a single sample wherever possible. Quality assurance and quality control (QAQC) procedures include regular insertion of certified reference materials, blanks, and field duplicates into the sample stream at a rate of approximately 9% of total samples in this release. All preparation and analytical work is performed by Activation Laboratories Ltd. (Actlabs) in Kamloops, British Columbia, Canada. Sample preparation follows Actlabs code RX1, involving crushing the entire sample (<7 kg) to at least 80% passing 2 mm, riffle splitting to obtain a 250 g sub-sample, and pulverizing (mild steel) to a minimum of 95% passing 105 µm. Actlabs code RX17 is also completed to determine pulp specific gravity. Crushing and pulverizing quality is monitored through Actlabs’ internal QAQC protocols. Gold is analyzed by fire assay with an atomic absorption spectroscopy (AAS) finish (Actlabs code 1A2-50 ORE), in which a 50 g pulp is fused with fire assay fluxes, preheated at 850 °C, heated further at 950 °C, and finished at 1,060 °C over a 60-minute fusion cycle. The resulting lead button is cupelled at 950 °C to produce a doré bead containing Au and Ag, which is then dissolved in aqua regia and analyzed by AAS. This method has a detection range of 0.01 to 100 g/t Au. Samples returning gold grades of =100 g/t Au are re-analyzed by fire assay with gravimetric finish (Actlabs code 1A3-50). In this process, gold is separated from silver in the doré bead by parting with nitric acid, and the gold residue is weighed gravimetrically on a microbalance. The 1A3-50 method has a detection range of 0.02 to 10,000 g/t Au.
