Latest Metallurgical Testing News

Argent Minerals has reported a landmark 133.1m intercept averaging 72.4 g/t silver equivalent from near surface at its Kempfield Project, including a stunning visible gold assay that deepens the resource by 80 metres and underscores its polymetallic potential.

Southern Palladium's latest metallurgical test work from its Bengwenyama PGM Project reveals a doubling in chromite concentrate recoveries and confirms the high-grade nature of its UG2 mineral resource, reshaping project economics and processing design.

Cobre Limited has kicked off a major 40,000-metre drilling campaign at its Sierra Atacama copper project in Chile, aiming to convert its existing NI 43-101 resource to JORC compliance and explore opportunities for a larger open-pit operation.

Cavalier Resources’ 2026 Pre-Feasibility Study update boosts the Stage 1 NPV of its Crawford Gold Project to A$77.2 million at A$6,500/oz gold, reflecting resilience amid supply chain pressures. The project maintains its ore reserve and pit design, with financing negotiations advancing.

Sun Silver has engaged global engineering firm Ausenco to lead critical concept and scoping studies for its Maverick Silver Project in Nevada, aiming to underpin a maiden Scoping Study by late 2026. The move leverages Ausenco’s North American precious metals expertise and comes as silver prices hover near US$77 an ounce, bolstering project economics.

Aldoro Resources has confirmed a major mineralisation extension at its Kameelburg deposit in Namibia, with drill hole DD004E intersecting 387.2 meters of continuous rare earth elements, strontium, niobium, and molybdenum. The Phase II drilling program is complete, setting the stage for bulk sampling.

Kingston Resources has delivered a fresh batch of high-grade polymetallic assay results from underground drilling at its Southern Ore Zone, Mineral Hill, reinforcing the geological model and underpinning near-term underground mining plans.

OD6 Metals has revealed exceptional channel sampling results from its Horseshoe Prospect within the Quinn Fluorspar Project, confirming extensive ultra-high-grade fluorspar mineralisation with grades peaking at 82% CaF2. These findings underscore the project's potential for direct shipping ore and acid-grade fluorspar production.

Tennant Minerals has intersected a thick zone of intense copper-gold-bismuth mineralisation at its Bluebird discovery, extending the high-grade resource footprint and underpinning plans for further exploration and metallurgical testing.

Critica Limited has achieved a significant breakthrough at its Jupiter Rare Earth Project, lifting magnet rare earth recovery to approximately 81% and total rare earth oxide recovery to around 71% through pilot plant optimisation. This advance strengthens the foundation for its ongoing scoping study and downstream processing plans.

Viking Mines has launched a field campaign at its Linka Tungsten Project targeting historical tailings and ore stockpiles as potential near-term, low-capital feed sources, complementing ongoing metallurgical advances and a planned June quarter drilling campaign amid record tungsten prices.

Blackstone Minerals has cleared a major regulatory hurdle with the lifting of a Cease and Desist Order at its Mankayan Copper-Gold Project, setting the stage for a pivotal Pre-Feasibility Study drilling campaign.
