Talisker completes final sorting test at Bralorne Gold Project

TORONTO, Sept. 17, 2026 (GLOBE NEWSWIRE) -- Talisker Resources Ltd. (“ Talisker ” or the “ Company ”) (TSX: TSK, OTCQB: TSKFF) is pleased to report results from its final test program completed at the Saskatchewan Research Council (" SRC "), in collaboration with TOMRA Mining and Stacy Freudigmann P.Eng from Canenco Consulting Corp. (“ Canenco ”). The program evaluated TOMRA's X-Ray Transmission (" XRT ") sorting technology and TOMRA's laser sorting technology as part of the Company's ongoing efforts to optimize the planned sorting circuit for the Bralorne Gold Project.

The test results demonstrated that the XRT sorter alone delivered strong performance by:

Rejecting 57% to 67% of waste material;

Increasing gold grades by 2.0x to 2.5x respectively; and

Recovering 87% to 84% of total contained gold respectively.

The addition of a downstream laser sorter increased overall gold recovery to greater than 95%. However, the additional recovered material was subeconomic. Adding the laser sorter into the sorting circuit would increase the mass of shipped material and dilute the overall grade of the sorted product, reducing the economic benefits of mass rejection during the Company's Direct Shipping Ore ("DSO") phase.

As a result of these findings, Talisker has elected to simplify the sorting circuit by removing the laser sorter from the plant design. The revised XRT-only flowsheet is expected to:

Maximize waste rejection and reduce overall tonnes shipped and processed to reduce transportation costs;

Significantly increase gold grades;

Reduce capital equipment and construction costs by approximately $4 million CAD;

Lower operating costs; and

Simplify plant design and operation.

The results validate the Company's strategy of prioritizing mass reduction and grade enhancement to improve the economics of DSO shipments for the Bralorne G
