Powerhaus Uranium entered the ASX with a $2.14 million annual loss, $1.51 million operating cash outflow and net liabilities at 30 June 2026. A subsequent $9 million IPO and the Hidden Bay acquisition have given the early-stage explorer a larger exploration runway, but drilling remains subject to approvals and future funding will still matter.

Lake Resources has reduced Kachi’s estimated capital cost by US$220 million and outlined a 25-year, 25,000-tonne-per-year operation. But the lithium developer still needs further funding, environmental approval, offtake and a final investment decision before construction can begin.

Patagonia Lithium has reported 15% total porosity and substantial free-fluid storage from Cilon Well 8, strengthening its interpretation of the aquifer’s pumping potential. The evidence is encouraging but remains incomplete, with four core results, further BMR Gamma data and a 72-hour pump test still outstanding.

LE Minerals finished FY2026 with an A$48.2 million statutory profit, but the result was driven by a one-off A$58.1 million after-tax gain from selling its Solaroz lithium project interest. The company ended the year with A$60.2 million in cash and term deposits as it reshapes its portfolio around Queensland and Utah exploration assets.

Argosy Minerals says laboratory-scale crystallisation testing has demonstrated a potential lithium chloride product yield above 99% at its 12,000-tonne-per-year Rincon project in Argentina. The results remove a key process uncertainty, but the project still depends on engineering completion, financing and a broader Definitive Feasibility Study.

Pursuit Minerals has started its first diamond hole at the Demasía tenement, testing whether lithium-bearing brines extend beyond the existing 1.264 million tonne LCE resource at Rio Grande Sur. Early packer tests recovered brine at shallow depths, but lithium assays are still pending.

Pursuit Minerals has secured environmental approvals to relocate its pilot plant to Rio Grande Sur and drill a new 500-metre hole at Demasía. The company has also applied to build commercial-scale evaporation ponds for its planned 5,000-tonne-per-year operation, although that approval remains outstanding.

NewPeak Metals will begin a minimum 1,000-metre Phase 2 diamond drilling program at Las Opeñas in Argentina in mid-October, targeting a potentially gold-richer zone west of its recent long intercepts. The campaign is funded from the company’s completed placement, but the higher-grade western extension remains untested.

Challenger Gold has set early 2029 as the target for commercial production from a stand-alone heap leach operation at its Hualilán project in Argentina. The roadmap brings engineering, drilling and financing into sharper focus, but still depends on a US$15 million debenture refinancing and a much larger project funding package.

Pursuit Minerals has recorded its highest lithium brine assay at Rio Grande Sur, with a deep packer sample returning 809mg/L from the Mito tenement in Argentina. More than 20 additional samples from the completed hole remain pending, while drilling has moved to DDH-4.

Piche Resources has begun a strategic review of its three remaining mineral projects and potential new opportunities after completing its rights issue, while searching for a chief executive to lead the next phase. The review will be supported by independent geological consultants, but no acquisition, disposal or revised exploration program has yet been announced.

Argosy Minerals has raised $3 million through a placement at a 19% discount, with an additional $500,000 sought via a Share Purchase Plan to fund its 12ktpa Rincon Lithium Project development.
