Talisker releases ore-sorting results at Bralorne

Executive Summary

• Talisker Resources released preliminary results from the second phase of laser‑based ore‑sorting tests on Bralorne gold project material, demonstrating high recoveries (95 %–99 %) and significant waste rejection (35 %–55 %).
• Full‑scale testing processed 371.3 kg at Tomra’s Wedel facility using the PRO Secondary LASER Dual Device, confirming the sorter’s ability to concentrate quartz vein material into high‑grade fractions.
• Results support fast‑tracking design, permitting and construction phases for underground production at Mustang Mine.

Key Details

• First‑phase benchmark: Average feed grade 14.4 g/t Au → sorted product grade 27.8 g/t Au.
• Second‑phase testing: 371.3 kg of run‑of‑mine material processed at Tomra’s test centre (Wedel, Germany) with multichannel laser‑sorting technology (PRO Secondary LASER Dual Device).
• Waste rejection: Between 35 % and 55 % of total rock mass rejected as waste.
• Gold recoveries: Achieved between 95 % and 99 % across test runs, indicating excellent suitability of Bralorne vein material for laser‑based sorting.
• Cascading procedure: Three sequential sorting settings (1–3) evaluated; setting 1 gave highest recovery with lower product grade, while setting 3 delivered the highest product grade but slightly reduced recovery.
• Assay plan: Post‑test samples sent for fire‑assay gold analysis and multi‑element ICP‑MS digestion; concentrated material to undergo further mineral processing and metallurgical testwork.
• Management comment: CEO Terry Harbort expressed confidence in the sorter’s performance and indicated plans to accelerate design, permitting and construction activities pending assay results.
