Talisker Reports Mustang Underground Face Sample Results Defining a 79-metre Strike Length High-grade Shoot Averaging 64.8 g/t on the 1030 Level

TORONTO, Sept. 09, 2026 (GLOBE NEWSWIRE) -- Talisker Resources Ltd. (“Talisker” or the “Company”) (TSX:TSK | OTCQB:TSKFF) is pleased to report continued success from underground development on the 1030 Level at the Mustang Mine, where the Company has successfully developed on a continuous 79-metre strike length of high-grade gold mineralization along the BK Vein. The zone comprises a well-defined banded quartz vein averaging 64.84 grams per tonne (g/t) gold across an average true width of 0.50 metres. These encouraging results extend the high-grade ore shoot from the 1045 Level, reported on April 15, 2026, and provide further validation of Talisker's geological model, with continued demonstration of increasing grade and improved continuity of mineralized structures with depth within the Mustang Mine at the Bralorne Gold Project, British Columbia, Canada.

Key Highlights:

• 496 g/t over 0.51 m within 156.97 g/t over 1.64 m from 1030 BK Vein, East Face No. 16
• 203 g/t over 0.54 m within 100.81 g/t over 1.09 m from 1030 BK Vein, East Face No. 18
• 167 g/t over 0.48 m within 61.27 g/t over 1.31 m from 1030 BK Vein, East Face No. 17
• 147 g/t over 0.35 m within 51.16 g/t over 1.21 m from 1030 BK Vein, East Face No. 22
• 114 g/t over 0.43 m within 43.58 g/t over 1.14 m from 1030 BK Vein, East Face No. 19
• 112 g/t over 0.47 m within 24.36 g/t over 2.39 m from 1030 BK Vein, East Face No. 28
• 74.7 g/t over 0.47 m within 37.53 g/t over 1.98 m from 1030 BK Vein, East Face No. 23
• 37.2 g/t over 0.80 m within 20.98 g/t over 1.50 m from 1030 BK Vein, East Face No. 28

Terry Harbort, CEO of Talisker commented, “These outstanding results from a well-defined ore shoot along the BK Vein demonstrate the remarkable structural and grade continuity of the auriferous quartz-vein systems across the Mustang Mine. With the BK structure delineated by diamond drilling over more than 750 metres of strike and remaining open beyond 500 metres depth, we see significant potential to extend known ore shoots and delineate additional high-grade shoots as mining advances. We look forward to reporting further results from our continued mining development and drilling at the Bralorne Gold Project.”

Qualified Person

The technical information contained in this news release has been reviewed and approved by Patrick Weaver, P.Geo., Talisker’s Chief Production Geologist, who is a Qualified Person as defined under Canadian National Instrument 43-101, Standards of Disclosure for Mineral Projects. Mr. Weaver is not independent of the Company in accordance with NI 43-101.

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 producing at the Mustang Mine. Talisker projects also include the Ladner Gold Project, an historic high-grade gold mine near Hope, British Columbia, 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 QAQC 

Chip sampling of underground ore headings at the Bralorne Gold Project is conducted by geologists using industry standard practices to sample across a horizontal 5 cm × 5 cm × up to 3.0 m zone across the entire face of the drift at a height of approximately 1.2 m above the sill/floor. 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.
