Latest Critical Minerals Exploration News

Rimfire Pacific Mining has expanded its NSW scandium inventory and reported preliminary leach results that could support a simpler extraction route. But the ASX explorer ended FY2026 with $583,770 in cash, negative working capital and an auditor-highlighted material uncertainty over its ability to continue as a going concern.

Golden Deeps has reported high-grade polymetallic results at its Graceland prospect in Namibia while stepping up deeper drilling across an 800-metre target corridor. The explorer ended FY2026 with $4.218 million in cash, but remains dependent on exploration success and future funding.

Resolution Minerals has turned Horse Heaven into the centre of its strategy, pairing broad gold drilling with high-grade antimony and tungsten test work. The expansion came with a sharply higher A$53.3 million FY2026 loss and a disclosed dependence on future funding.

Battery Age Minerals finished FY26 with stronger cash reserves and drilling progress across Austria and Argentina, but warned that further funding or asset realisations are needed to sustain planned exploration. The company reported a $4.97 million loss, including a $2.60 million non-cash charge linked to its diluted Eminence Minerals holding.

Pioneer Minerals has warned of a material uncertainty over its ability to continue as a going concern after closing FY2026 with just A$80,302 in cash. The company is relying on a proposed A$2.5 million capital raising while pushing its Idaho tungsten-gold-gallium project towards maiden drilling.

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.

Resource Base Limited (ASX:RBX) reduced its FY2026 loss, but ended the year with only $140,776 in cash and an auditor warning of material uncertainty over its ability to continue as a going concern. The company is relying on fresh capital to advance early-stage titanium targets in South Australia.

New Frontier Minerals advanced its copper and rare earths portfolio during FY2026, but the annual report highlights a material uncertainty over its ability to continue as a going concern. The company ended the year with $1.23 million in cash after a $2.25 million placement and ongoing exploration spending.

QEM Limited (ASX:QEM) has suspended non-essential work at its Julia Creek vanadium project after metallurgical results undermined the 2024 Scoping Study. The loss-making explorer is now relying on newly acquired Idaho projects, fresh capital and further exploration to justify its next chapter.

Perpetual Resources has warned of material uncertainty over its ability to continue as a going concern after its FY2026 loss more than tripled. The ASX-listed explorer finished the year with A$2.34 million in cash, but remains dependent on further capital raisings to fund Nevada Scheelite and Brazilian exploration.
