Adavale Resources is presenting its 610-square-kilometre Parkes Gold Project as a belt-scale opportunity with 383,300 ounces of reported gold resources and existing processing infrastructure. The next test is whether metallurgical work, a scoping study and funding can turn that inventory into a credible development plan.

Western Gold Resources has expanded the Gold Duke resource and production target, but its annual report carries a material uncertainty over the company’s ability to continue as a going concern. The project still needs a processing pathway, heritage consultation and further funding before production can begin.

KGL Resources says its Jervois copper project is funded through construction and ramp-up after a US$300 million Wheaton agreement and a post-year-end A$300 million equity raising. The company is now targeting a final investment decision in the second half of 2026 and first copper concentrate in 2028, while its annual report highlights the execution risks still attached to that timetable.

Cyprium Metals says its long-delayed Nifty Copper Complex is entering the final commissioning phase, with first copper cathode production expected in the December quarter of 2026. The restart is backed by A$121 million in equity raisings, a refinanced US$27.3 million loan facility and A$68.5 million in cash at year-end.

Ark Mines has reported a FY2026 profit after receiving Queensland-backed funding, while its Sandy Mitchell rare earths resource expanded to 379.4 million tonnes after year end. The project now has development approvals and commercial-grade testwork behind it, but no Ore Reserve or mining decision yet.

St George Mining’s Araxá project now boasts a 111.2Mt rare earths resource after a major post-year-end upgrade, alongside 630,000 tonnes of contained niobium. The 2026 annual report shows a company moving rapidly towards development, but still without an ore reserve, mine design or production decision.

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.

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.

Revolver Resources has taken its Dianne Copper Mine Project from study towards construction readiness, with a larger resource, secured approvals and a forecast $125.7 million pre-tax cash flow. But the restart still depends on project-level funding before a Final Investment Decision can be made.

Brazilian Critical Minerals has reported striking economics for its Ema rare earths project, including a US$1.47 billion post-tax NPV, 105% IRR and six-month payback. The company’s A$7.87 million FY2026 loss, December debt maturity, permitting requirements and unresolved Drake dispute leave the development case dependent on execution and further funding.

Australian Rare Earths has converted Koppamurra from an exploration story into a defined rare earths development case, with an A$858 million after-tax PFS NPV and a maiden Ore Reserve. The next test is less geological than financial: the company must fund the path from pilot processing to construction while carrying a material going-concern warning.

Lefroy Exploration has moved from explorer to gold producer after Lucky Strike delivered its first gold, while Mt Martin and Burns advanced towards potential development. The milestone comes alongside a $2.136 million loss and an auditor warning that uncertain profit distributions may require further funding.
