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.

PTR Minerals has posted a 463 million tonne maiden resource for its Rosewood titanium project, backed by strong early processing results and fresh funding. The next test is whether the large geological inventory can become an economically viable mine.

Oceana Metals has begun a 20,000-metre diamond drilling campaign at its Serra Negra rare earths project in Brazil, backed by high-grade historic assays and fresh capital. But the company’s $11.5 million FY2026 loss and an auditor-highlighted material uncertainty over going concern add a harder edge to the exploration story.

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.

Mammoth Minerals expanded its Nevada exploration portfolio and drilled more than 21,000 metres at the Buster Trend, but its FY2026 report also highlights a material uncertainty over its ability to continue as a going concern. The company posted a larger loss and remains dependent on future equity funding to sustain exploration.

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.

The company is targeting a 2027 investment decision while holding less than A$1 million in year-end cash and navigating a leadership change.

Tennant Minerals has reported a high-grade maiden resource and further strong drilling at its Bluebird copper-gold discovery, but the annual report carries a material uncertainty over the company’s ability to continue as a going concern. A $2.8 million capital raise completed around year-end provides near-term funding, while further exploration and processing studies remain ahead.

West Cobar Metals ended FY2026 with more cash but a larger loss and an auditor-highlighted material uncertainty over its ability to continue without further funding. Exploration advanced across Salazar and Cobar West, but the company remains dependent on equity markets to keep its programmes moving.

Temas Resources and SAGA Metals have begun an eight-week optimisation program aimed at turning strong laboratory recoveries into a defined processing flowsheet and first high-purity titanium, vanadium and iron products. A successful stage could lead to a C$650,000-C$750,000 mini-pilot, although that funding remains subject to technical results and SAGA approval.

Prairie Limited has secured C$6.3 million in interest-free Canadian government financing to fund the next construction phase of its Saskatchewan lithium project. The company is targeting commissioning and first lithium brine production from its initial commercial well in Q4 2026.
