New Talisman reports progress and challenges in gold concentrate production

New Talisman Gold Mines Limited (NTL) dispatched its first bulk consignment of 29kg (wet) concentrate in early August 2025. This bulk shipment faced a 10-day delay due to Australian Customs inspection, despite earlier small samples being processed quickly. The refiner, after testing 2kg samples at 1100g/tonne, has requested a higher grade concentrate of over 5000g/tonne, which NTL's team believes is achievable by repassing the concentrate over a shaker table.

A further 231kg (wet) of concentrate has since been produced from approximately 70 tonnes of stockpiled Run of Mine (ROM) Talisman ore, which itself consists of about 160 tonnes from various sources. The company reported a challenge with gold accumulation in the processing plant's new ball mill, expected to resolve as gaps fill. Tailings consistently show under 2g/t Au, indicating efficient extraction of heavy minerals. Concentrate per tonne of ROM has varied, from 1-2 kg to 7.5kg for quartz-laden material.

The company's processing plant is now operating predictably, with capacity to handle bulk sampling volumes. An initial 320 tonnes per month of bulk sampling from Mystery North indicates a break-even point of 8g recovered gold at approximate All-In Sustaining Cost (AISC). NTL plans to seek further working capital through a placement facility to fund bulk sampling of the Mystery reef complex.
