Latest Metallurgical Test Results News

Lefroy Exploration’s metallurgical tests reveal up to 97% gold recovery from its Burns High-Grade Deposit, underpinning plans for a resource update by September 2026.

OzAurum Resources has completed its extensive grade control drilling at Mulgabbie North, delivering consistent high-grade gold intercepts at shallow depths and progressing site civil works for heap leach infrastructure.

Savannah Goldfields reports metallurgical test results showing over 70% gold recovery from sulphide ores at Electric Light and Red Dam, processed through the existing Georgetown plant. Historic data suggests flotation could boost recoveries above 94%, with further test work planned.

Benz Mining reports strong metallurgical test results from the Icon deposit, showing up to 95.5% gold extraction within 24 hours and potential for broader mineralised halo to contribute to mill feed.

Caprice Resources reports metallurgical testwork on its Vadrians deposit achieving up to 94% gold recovery via conventional gravity and CIL processing, supporting a low-cost extraction pathway at its Island Gold Project.

Brazilian Critical Minerals (ASX: BCM) reports robust magnesium sulphate leach results from its 2025 drilling at the Ema project, validating key assumptions for a long-life, low-cost rare earth operation.

High-Tech Metals has reported exceptional metallurgical test results from its Wagtail Gold Deposit at Mt Fisher, confirming high gold recoveries and processing flexibility that could lower costs and boost throughput.

Red Mountain Mining has produced a high-grade 51.8% antimony concentrate from Oaky Creek with excellent 85% recovery, setting the stage for upcoming drilling to define the resource along a 3km mineralised strike in NSW.

Metal Bank has secured $1.2 million through a placement at a 30% premium, aiming to fast-track production at its Seven Leaders deposit and advance the Homestead and Winja gold projects at Livingstone.

Encounter Resources has achieved strong metallurgical recoveries of 51-53% niobium and up to 57% Nb2O5 concentrate grade from the Green deposit at its Aileron Project, validating conventional processing methods and supporting multi-decade mining potential.

Bayan Mining and US Critical Materials have signed a non-binding MoU to develop rare-earth processing technologies licensed from the Colorado School of Mines, targeting high-grade mineralisation at the Sheep Creek Project in Montana. The collaboration aims to support a US-based rare earth supply chain with potential strategic investment on the horizon.

Raiden Resources has uncovered extensive new arsenic-in-soil anomalies at its Vuzel Gold Project in Bulgaria, signaling a potentially larger mineralised system beyond the previously drilled zone. Follow-up exploration and permitting efforts continue alongside pending metallurgical test results.
