White Cliff Minerals has expanded its Rae Copper-Silver Project into a multi-kilometre copper system, with a peak interval of 21.1% copper and recoveries reaching 95.4%. The exploration progress came alongside an A$18.8 million FY26 loss, A$14.5 million operating cash outflow and an auditor-highlighted material uncertainty over going concern.

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.

Truscott Mining has confirmed gold mineralisation at a new Westminster structural target and is preparing diamond drilling ahead of a JORC 2012 resource update. The exploration progress comes alongside a larger loss, ongoing funding dependence and an auditor-highlighted material uncertainty over its ability to continue as a going concern.

Cauldron Energy has expanded its defined Yanrey uranium resource to 55.6 million pounds of U3O8 after a successful exploration year, while warning that further funding will be needed to continue operations. The project remains dependent on a change to Western Australia’s uranium mining policy.

North Stawell Minerals has expanded and refined its Darlington-Caledonia exploration targets, including a post-year-end intercept of 0.4 metres at 17.1 g/t gold. But the gold explorer ended FY2026 with $701,960 in cash, a deeper loss and an auditor warning that further funding is needed to sustain operations.

Sultan Resources has reported a $1.48 million FY2026 loss and an auditor-highlighted material uncertainty over its ability to continue as a going concern. The explorer is seeking to fund early-stage Lachlan Fold Belt work while pursuing a new Namibia opportunity and a post-year-end $1.316 million placement.

PLC Resources has repositioned around Western Australian gold and copper exploration, securing a maiden 13,000-ounce Inferred Resource at Wadgingarra and full ownership of Yalgoo. But the FY2026 annual report also carries a material uncertainty related to going concern, leaving future exploration dependent on additional funding and exploration success.

ACDC Metals enters FY27 with a larger Nevada exploration footprint and a 10-year licence over its Goschen Central rare earths project, but a sharply higher annual loss and ongoing funding needs remain part of the picture. The company plans up to 2,500 metres of reverse-circulation drilling at Mount Jackson in Q4 CY2026.

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.

Solara Minerals has reported a sharply wider FY2026 loss after impairing $3.14 million of exploration assets, while cash fell to $2.03 million. The early-stage explorer expanded its Bryah Basin portfolio but says further funding may be needed to continue exploration.

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.

Melbana Energy’s Block 9 project remains on care and maintenance after a partner default and US sanctions on CUPET, despite improved geological understanding from Amistad-2. The company ended FY2026 with $472,504 in cash and warned that additional funding is required to continue.
