Talisker Receives Preliminary Results from the Second Phase of Ore Sorting Studies for the Bralorne Gold Project
Talisker Resources (OTCQX:TSKFF) has announced promising preliminary results from the second phase of laser-based ore sorting studies at its Bralorne Gold Project in British Columbia. The testing, conducted at Tomra's test centre in Germany, processed 371.3 kilograms of material using multi-channel laser sorting technologies.
The first phase demonstrated impressive results, increasing average feed grade from 14.4 g/t gold to 27.8 g/t gold, with gold recoveries between 95% and 99% while rejecting 35-55% of total rock mass as waste. The second phase utilized a cascading procedure with three sequential sorting steps, each with increasing waste sensitivity, allowing for simulation of potential production outcomes.

La prima fase aveva già mostrato ottimi risultati, aumentando la tenore medio di alimentazione da 14,4 g/t d'oro a 27,8 g/t d'oro, con recuperi d'oro compresi tra il 95% e il 99% e scartando il 35-55% della massa rocciosa come rifiuto. La seconda fase ha adottato una procedura a cascata con tre passaggi di selezione sequenziali, ciascuno con crescente sensibilità allo scarto, permettendo di simulare possibili esiti di produzione.

TORONTO, Sept. 03, 2025 (GLOBE NEWSWIRE) -- Talisker Resources Ltd. (“Talisker” or the “Company”) (TSX: TSK, OTCQX: TSKFF) is pleased to announce preliminary results from the second stage of laser-based ore-sorting of material from the Company’s Bralorne Gold Project located in British Columbia (“Bralorne”).
The first phase of ore sorting at Bralorne (see press release of February 26, 2025) resulted in an increase of the average feed grade from 14.4 grams per tonne gold to a final sorted product grade of 27.8 grams per tonne gold. The preliminary results also rejected between
The second stage of testing was a run of mine test-work program using full-scale equipment to allow for a direct comparison to full-scale production projections. A total of 371.3 kilograms of material was processed at Tomra’s test centre in Wedel, Germany using multi-channel laser sorting technologies, specifically the PRO Secondary LASER Dual Device. Tomra’s laser sorting uses a multi-channel laser system to scan the surface of rock particles. The degrees of diffusion (scattering effects) on the surface of the rocks varies with distinct types of minerals, as well as with their crystallinity and colour. The different spot sizes of the diffusion measured are analysed using Tomra’s image processing software providing for the detection of small variances in surface patterns, even when those patterns are identical in colour. The different selected colour classes (coloured pixels) are then assessed as a percentage of the single rock area with this percentage used as a parameter to determine and to set the sorting cut-off grade.
Terry Harbort, CEO of Talisker stated, “We are impressed with these results using our run of mine material and full-scale equipment. We can clearly see the ability of the sorter to concentrate mineralized quartz vein material into the high-grade and medium-grade fractions while separating waste material into the pure waste and low-grade fractions (see figures 1 – 3). As we await the corresponding assay results for each fraction, we will be fast-tracking to the design, permitting and construction phases.”
The testing also involved a cascading procedure where gold bearing material was passed multiple times through the sorting device. The cascading procedure involved three sequential sorting steps, each with increasing sensitivity to waste referred to as settings 1 through 3. As the sensitivity increased from setting 1 to setting 3, the mass pull to waste also increased. At setting 1, the sorting produced the highest recovery but with a lower product grade. In contrast, setting 3 yielded the highest product grade, albeit with relatively lower recovery. This approach allows simulation of potential outcomes by applying a specific sensitivity in a single step sorting process.

Upon completion of the ore sorter testing, samples were sent for gold analysis by fire assay and multi-element analysis by four acid digestion followed by inductively coupled plasma mass spectrometry. In addition, material that has been physically concentrated by the ore sorting process will be sent for mineral processing and metallurgical test work.
