Accelerate Resources has completed three large-diameter diamond holes at its Area 42 manganese project, with visual mineralisation recorded in each hole. The standout hole covered a 72m downhole span and ended in mineralised chert breccia, but assays and metallurgical results are still pending.

Fulcrum Lithium has staked 41 additional claims around its Alkali Flats project in Nevada and reported up to 79% lithium extraction from acid-free roast and water-leach tests. The results improve on earlier water-leach work, although they remain below the company’s 93% to 96% sulfuric-acid benchmark and come from scoping-level tests.

Heavy Rare Earths has identified high-grade heavy rare earth zones at Subron while preparing drilling across its South Australian portfolio. But the FY2026 report also highlights a material uncertainty over the company’s ability to continue as a going concern, with only $459,327 in cash at year-end.

MRG Metals has reported exceptional rare earth grades at its newly acquired Garies project and advanced its Mozambique portfolio, but the explorer remains dependent on capital markets. The FY26 annual report flags material uncertainty over going concern despite a subsequent A$725,000 placement and a further share purchase plan.

GreenX Metals has put a conceptual copper-silver target at Tannenberg and a major Poland arbitration award at the centre of its next phase. The annual report also shows the cost of that strategy: a $12.34 million loss, a $4.42 million project impairment and continued reliance on equity funding.

Osmond Resources has outlined a 60.0 million tonne maiden JORC resource at its Orión critical minerals project in Spain, but most of the inventory remains Inferred and unproven economically. The company will resume drilling in October, with an updated estimate targeted for the first quarter of 2027.

G50 Corp has moved from early-stage exploration towards a two-project drilling campaign, backed by a post-year-end A$26.25 million placement. The company remains loss-making and reliant on exploration success, but says the capital allows uninterrupted work at its Arizona and Nevada projects.

Cadoux says resampling of 21 historical Danube drill holes has extended rare earth-zircon mineralisation up to 1.4 kilometres north of its June Exploration Target and opened a southern target area. The results move the project towards planned infill drilling, a maiden Mineral Resource and a Scoping Study, but key mineralogy and access hurdles remain.

Omnia Metals has shifted its exploration focus to US antimony, silver, rare earths and gallium projects, backed by $3.1 million in equity raisings. Early Montana sampling produced follow-up targets, but the company remains loss-making and says the results are reconnaissance-scale rather than evidence of a resource.

ACDC Metals enters FY27 with a larger Nevada exploration footprint and a 10-year licence over its Goschen Central rare earths project, but a sharply higher annual loss and ongoing funding needs remain part of the picture. The company plans up to 2,500 metres of reverse-circulation drilling at Mount Jackson in Q4 CY2026.

Eclipse Metals has enlarged its flagship Grønnedal rare-earth resource to 208 million tonnes and added a maiden Ivigtût critical-minerals inventory. The gains came alongside a higher annual loss, a material going-concern uncertainty and an unresolved legal claim.

Albright Metals has established a 54,200-ounce JORC 2012 Mineral Resource at the Vail Road deposit in Canada, including 22,500 ounces in the higher-confidence Indicated category. The estimate gives the company a technical foundation for a Scoping Study, but mine economics and metallurgy remain untested.
