Latest Metallurgical Testing News

AuKing Mining has reported wide, high-grade rare earth intersections from maiden RC drilling at its Tundulu project in Malawi, including 91 metres at 1.51% TREO. The results also reveal unusually strong heavy rare earth enrichment and have prompted the company to fast-track a maiden resource estimate targeted before the end of 2026.

Ariana Resources has re-released its Dokwe drilling update after adding JORC disclosures, leaving the underlying results unchanged. The announcement reports broad gold intercepts, eight tonnes of samples sent to China for feasibility-level metallurgical testing and further work aimed at advancing the Zimbabwe project’s DFS.

Tivan has secured the regulatory and cultural heritage clearances needed to advance an 8,000-metre drilling campaign at its Molyhil tungsten project in the Northern Territory. The company will also issue 3.84 million shares as part-payment for the project acquisition, while its feasibility and proposed funding plans remain unfinished.

Gorilla Gold Mines has extended its Lakeview drilling story with a 7.0-metre intercept grading 12.6g/t gold, while securing the final permit for underground activities at Sovereign. Metallurgical testing across three Comet Vale deposits also returned average 94.6% gold recovery after 48 hours at a relatively coarse grind size.

Manuka Resources has reported several high-grade, shallow gold intersections from its Pipeline Ridge drilling campaign, led by 32 metres at 7.98 grams per tonne. The results support a maiden resource estimate, but metallurgy, true widths and resource classification remain unresolved.

Greenvale Energy is expanding the final phase of Alpha Test Program 7 after Technix failed to produce a compliant C-170 paving-grade binder. SAMI Bitumen Technologies will now test conventional bitumen blending and additive-based formulations, with results expected from a six to eight-week laboratory program.

Catalyst Metals has lifted the Keillor gold Resource from 81koz to 307koz after a major drilling campaign, while the operating mine ramps up near the Plutonic processing plant. The company expects an Ore Reserve update to extend Keillor’s initial three-year mine life.

Nelson Resources has lodged a Notice of Intent to collect up to 1,000 short tons of remnant mineralised material from the Orleans Mine in Nevada for bulk-scale metallurgical testing. The program could test whether laboratory recovery results translate to commercial-mill conditions, but remains subject to approval, bonding and the appointment of a third-party mill.

Brazilian Rare Earths has commissioned its Stage I beneficiation pilot plant in Bahia and produced its first rare earth mineral concentrate. Partners will contribute R$6.4 million, or about A$1.7 million, towards the next hydrometallurgical stage planned for commissioning in Q2 2027.

Recharge Metals has identified materially higher tungsten grades in selected re-assayed pulps from its Brandy Hill South copper project in Western Australia. The results strengthen the case for a broad Cu-W-Mo system, but the most important evidence still sits in more than 1,000 samples awaiting testing.

Power Minerals has secured priority-project treatment from Minas Gerais for its Morro do Ferro rare earths project, directing future licensing through a specialised state pathway. The agreement improves institutional access but stops well short of environmental approval, project finance or a construction timetable.

Paterson Resources is set to start an extensive drilling campaign at its Grace Gold Project, aiming to upgrade its 200,000-ounce inferred gold resource and extend high-grade mineralisation along a 1.3km strike in the Paterson Province.
