Talisker Reports Mustang Underground Face Sample Results Including 886 g/t over 0.51m within 254.5 g/t over 2.74m on 1060 Level and Defines a 60 metre Strike Length High-grade Shoot Averaging 27 g/t on the 1045 Level

TORONTO, April 15, 2026 (GLOBE NEWSWIRE) -- Talisker Resources Ltd. (“Talisker” or the “Company”) (TSX: TSK, OTCQB: TSKFF) is pleased to report the development on the newly established 1045 Level along the BK Vein at the Mustang Mine where the Company has successfully intersected a continuous 60-metre strike length of high-grade mineralization. The zone comprises a well-defined banded quartz vein averaging 27 grams per tonne (g/t) gold across an average width of 0.85 metres with a total of 384 visible gold occurrences across 17 of the 25 faces channeled on the structure. This result highlights the strong continuity of the mineralized structures within the Mustang Mine and further supports Talisker’s geological model. Ongoing development continues to demonstrate the robustness and expansion potential of the BK Vein system, reinforcing confidence in the asset’s ability to deliver consistent high-grade material.

Additionally, Talisker is pleased to report that new development along the BK Vein on the 1060 Level at the Mustang Mine has intersected a high-grade ore shoot, located approximately 15 metres beyond previously developed workings. This discovery underscores the significant upside potential for continued resource expansion at depth and along strike within the BK Vein system. 

Key Highlights:

• 866 g/t over 0.51 m within 254.52 g/t over 2.74 m from BK Vein, West Face No. 11
• 413 g/t over 0.38 m within 130.28 g/t over 1.30 m from BK Vein, East Face No. 26
• 380 g/t over 0.35 m within 75.44 g/t over 1.88 m from BK Vein, East Face No. 2
• 234 g/t over 0.57 m within 102.33 g/t over 1.32 m from BK Vein, East Face No. 28
• 142 g/t over 0.40 m within 41.03 g/t over 1.44 m with from BK Vein, East Face No. 4
• 89.8 g/t over 0.49 m within 33.62 g/t over 1.43 m from BK Vein, East Face No. 23
• 80.3 g/t over 0.47 m within 24.40 g/t over 1.63 m from BK Vein, East Face No. 18
• 66.9 g/t over 0.45 m within 19.53 g/t over 1.84 m from BK Vein, East Face No. 5
• 32.3 g/t over 0.67 m within 17.65 g/t over 1.33 m from BK Vein, East Face No. 25
• 26.9 g/t over 0.88 m within 12.51 g/t over 2.17 m from BK Vein, West Face No. 10
• 14.6 g/t over 0.48 m within 6.03 g/t over 1.31 m from BK Vein, West Face No. 9
  

Terry Harbort, CEO of Talisker commented, “These new face sample results from the 1060 level and the new development on the 1045 level strongly support our upcoming stope extraction from these levels. With ramp and waste development also nearing completion on the 1030 level, we look forward to following these shoots further at depth.”

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.

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 advanced stage project with significant exploration potential from an historical high-grade producing gold mine and the Spences Bridge Project where the Company has a significant landholding in 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 0.35 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 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.
