Talisker samples 0.51 m of 610 g/t Au at Mustang mine

2026-07-21 12:25 ET - News Release

Mr. Terry Harbort reports

TALISKER 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. has 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 metre. These encouraging 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 grams per tonne over 0.58 metre 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.

Terry Harbort, chief executive officer of Talisker, commented: "These astounding high-grade results over nearly 130 metres from our underground face sampling once again demonstrate the world-class grade and continuity of the Bralorne gold project. Following on from the previous results from the BK vein that returned a 60 m strike length at 27 g/t also on the 1,045 m level, we are pleased that our lateral development is returning results well beyond our expectations. We look forward to receiving our upcoming assays from our development on the 1105m level above and from the new 1,030 m level, 15 m below the 1045."

About Talisker Resources Ltd.

Talisker is a junior resource company involved in the exploration and development of gold projects in British Columbia, Canada. Talisker's flagship asset is the high-grade, fully permitted Bralorne gold project where the company is producing at the Mustang mine. Talisker projects also include the Ladner gold project, an historic high-grade gold mine near Hope, B.C., with significant exploration potential, and the Spences Bridge project, where the company has a significant landholding in the emerging Spences Bridge gold belt, as well as several other early stage greenfields projects.

Sample preparation and QA/QC (quality assurance/quality control)

Channel sampling of underground ore headings at the Bralorne gold project was historically conducted by geologists using a rock saw to cut a horizontal five centimetres by five centimetres by 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 procedures include regular insertion of certified reference materials, blanks and field duplicates into the sample stream at a rate of approximately 9 per cent of total samples in this release.

All preparation and analytical work is performed by Activation Laboratories Ltd. (Actlabs) in Kamloops, B.C., Canada. Sample preparation follows Actlabs code RX1, involving crushing the entire sample (less than seven kilograms) to at least 80 per cent passing two millimetres, riffle splitting to obtain a 250-gram subsample and pulverizing (mild steel) to a minimum of 95 per cent passing 105 micrometres. Actlabs code RX17 is also completed to determine pulp specific gravity. Crushing and pulverizing quality is monitored through Actlabs's internal QA/QC 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 degrees Celsius, heated further at 950 degrees C and finished at 1,060 degrees C over a 60-minute fusion cycle. The resulting lead button is cupelled at 950 degree C to produce a dore 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 greater than or equal to 100 g/t Au are reanalyzed by fire assay with gravimetric finish (Actlabs code 1A3-50). In this process, gold is separated from silver in the dore 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.
