Talisker Receives Assay Results from 1060 Level Lateral Development at the Mustang Mine

TORONTO, Aug. 18, 2025 (GLOBE NEWSWIRE) -- Talisker Resources Ltd. (“Talisker” or the “Company”) (TSX: TSK, OTCQX: TSKFF) is pleased to announce that the Company has received additional assay results from underground face sampling of lateral development from the 1060 level at the Mustang Mine. These results follow on from the previous two press releases detailing results from the 1075 and the 1105 levels, situated vertically above the 1060 Level. Additional results for the 1120 level are expected shortly.

Key Highlights:

• 220.0 g/t over 0.50m within 40.44 g/t over 2.76m from Alhambra Vein, West Face No. 8 (sample X000816)
• 43.3 g/t over 0.85m within 13.0 g/t over 2.93m from Alhambra Vein, West Face No. 2 (sample X000443)
• 37.0 g/t over 0.85m within 11.0 g/t over 2.86m from Alhambra Vein, West Face No. 4 (sample X000507)
• 19.7 g/t over 0.66m within 5.6 g/t over 2.4m from Alhambra Vein, West Face No. 3 (sample X000457)
• 12.55 g/t over 0.74m within 5.05 g/t over 2.54m from Alhambra Vein, West Face No. 1 (sample X000316)
  

Terry Harbort, CEO of Talisker, stated, “The Alhambra Vein continues to deliver consistent high-grade results now extending down to the 1060 level. With our first production stope situated above these samples reaching up to the 1075 level we are excited to complete the extraction of this material. Talisker expects to receive results of the face sampling from the 1120 level, some 60 metres above the 1060 before the end of the month.”

Qualified Person

The technical information contained in this news release relating to the drill results at the Bralorne Gold Project has been approved by Leonardo de Souza (BSc, AusIMM (CP) Membership 224827), Talisker’s Vice President, Exploration and Resource Development, who is a “qualified person” within the meaning of National Instrument 43-101, Standards of Disclosure for Mineral Projects.

About Talisker Resources Ltd.

Talisker (taliskerresources.com) 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 currently transitioning into underground production at the Mustang Mine. Talisker projects also include the Ladner Gold Project, an advanced stage project with significant exploration potential from an historical high-grade producing gold mine and the Spences Bridge Project where the Company holds ~85% of the emerging Spences Bridge Gold Belt, and several other early-stage Greenfields projects.

Sample Preparation and QAQC

Channel sampling of underground ore headings at the Bralorne Gold Project is conducted by Geologists using a rock-saw to cut a horizontal 5 cm x 5 cm x 3.0 m groove across the entire face of the drift at a height of 1.2 m off the sill. Individual samples range from 0.5 m to 1.5 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 taken 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.
