Liontown has approved a $389 million expansion of Kathleen Valley, targeting average spodumene concentrate production of about 780,000 dry metric tonnes a year from FY30. The project is expected to lower unit costs, but its economics rely on lithium price assumptions, execution and a production inventory containing 21.5% inferred resources.

Castle Minerals has reported a $3.23 million net loss for FY2026, with its auditor highlighting material uncertainty over the explorer’s ability to continue without further capital or spending cuts. The company is redirecting its portfolio towards gold assets in Côte d’Ivoire and Western Australia, backed by a partly completed $4 million post-year-end placement.

Black Canyon has established a maiden 23.6Mt manganese resource at Wandanya in Western Australia, alongside 12.5Mt of iron mineralisation. The high-confidence estimate includes potential direct-shipping material, while a scoping study is targeted for completion in December.

Peninsula Energy’s low-pH uranium restart delivered stronger grades but struggled to move enough solution through the Lance wellfields, forcing guidance to be withdrawn and triggering a US$50.1 million impairment.

Firebird Metals is moving from manganese exploration towards downstream battery materials, with its Perth demonstration plant backed by a A$2 million ARENA grant.

PhosCo has expanded its Gasaat phosphate project with a 166.6Mt resource and new processing results, but its auditor has flagged material uncertainty over the company’s ability to continue as a going concern. The ASX-listed explorer ended FY2026 with $5.86 million in cash, a $4.48 million consolidated loss and a $2.71 million working capital deficit.

Rhythm Biosciences has moved ColoSTAT and geneType into commercial use, recording its first sales during FY2026. But with sales revenue of just $85,339, a $5.93 million loss and an auditor-flagged going-concern uncertainty, the next phase will be judged on cash generation and repeat adoption.

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.

Viva Leisure used FY2026 to prove its existing club network could generate stronger returns without rapid expansion, lifting revenue 12.2% and underlying NPAT 46.4%.
