29Metals has announced the results from recent drilling programs at its Golden Grove mine, highlighting more high-grade copper and zinc intercepts which could extend the project’s mine life.
The existing Gossan Hill deposit has been extended as a result of drilling, with indications pointing to mineral resource growth at the Tryall and Oizon mines.
At Tryall, resource extension drilling returned a strong copper-gold-silver intersection of 16.5m at 2.1 per cent copper, 1.8 grams per tonne (g/t) gold and 19 g/t Cu, 1.8g/t Au and 19g/t of silver from 103.5m.
This included a higher-grade core of 9.5m at 3.2 per cent copper, 1.8g/t gold and 22g/t of silver.
At Oizon and Hougoumont, drilling returned additional strong intersections of critical minerals – 42.2m at 9.5 per cent zinc, 0.2 per cent copper, 0.9 g/t gold, 38 g/t silver and 0.7 per cent lead from 388m.
“High-grade resource extension results from the 2025 drill program continue to highlight the potential for mine life extensions in easily accessible areas of Gossan Hill, providing opportunity to leverage existing underground infrastructure and development to build flexibility into the Golden Grove life of mine plan,” 29Metals chief executive officer James Palmer said.
“Particularly at Tryall, which is a shallow Gossan Hill deposit with established infrastructure, and at Oizon where mining will commence in late 2026.”
Golden Grove has an already-established mine life of more than 10 years, with ore reserves sitting at 16.5 million tonnes.
Rate of mining at the project, in 2024, sat at 1.47 million tonnes per annum, which could increase in the coming year thanks to investment.
