Estrella Resources has identified copper-bearing porphyritic diorite and gold at nine locations around Timor-Leste’s Laleno Dome, strengthening the case for a broader intrusion-related system. The geological signal is encouraging, but drilling approval and representative follow-up work remain outstanding.

Mantle Minerals reported a $12.50 million FY2026 profit after selling Mt Roe Mining to Northern Star for $13.5 million, while continuing operations remained loss-making. The company ended the year with $5.50 million in cash and is redirecting capital towards Yule River and Carlton Hill exploration.

Fulcrum Lithium has delivered a 10.7 million tonne lithium carbonate equivalent maiden resource at Alkali Flats, but its auditor has warned that additional funding is needed to sustain exploration. Cash fell to $1.58 million at 30 June 2026 as the company advanced drilling, metallurgy and resource modelling in Nevada.

Arika Resources has consolidated full ownership of its two Western Australian gold projects after a year of expanding mineralisation and fresh high-grade targets. The exploration story is gathering momentum, but auditors have flagged material uncertainty around funding as the company moves into a more than 20,000-metre drilling campaign.

Bubalus Resources finished 2026 with $3.03 million in cash after posting a $1.62 million loss and writing off $1.01 million of exploration assets. The exploration company is narrowing its focus across Victorian gold, rare earths and lithium targets, but says further funding may be required.

Evion Group has moved its flagship Maniry graphite project into the development stage and secured a binding German offtake terms sheet, but its FY2026 accounts carry a material going concern warning. The company also faces an unpaid A$730,000 placement shortfall as it funds graphite, fluorspar and downstream expansion plans.

Litchfield Minerals has expanded its Harts Range exploration model, raised A$8 million and ended FY2026 with A$4.6 million in cash. The opportunity is growing, but the auditor flagged material uncertainty over the company’s ability to fund future operations.

Stellar Resources has lifted its Heemskirk tin resource to 115.3kt of contained tin while technical studies move toward a prefeasibility study outcome. The company is better funded, but remains pre-revenue and faces the usual capital, permitting and execution hurdles of mine development.

Flynn Gold is pushing Golden Ridge and Firetower towards resource definition, but its FY2026 annual report flags a material going-concern uncertainty and a cash balance of just A$1.11 million. A partially underwritten A$3 million rights issue now sits alongside drilling, permitting and a non-binding processing pathway with Henty Gold Mine.

Tambourah Metals has reported high-grade exploration results at Beatty Park South and Tambourah King, alongside a stronger cash position and a reduced annual loss. The projects remain at exploration stage, with drilling and resource modelling now carrying the story forward.

Peako has completed its 100% acquisition of six Saudi Arabian gold projects covering 862 square kilometres, clearing the way for maiden drilling from October. Recent fieldwork has identified extensive high-grade vein systems, but the reported grades remain exploration indicators rather than a mineral resource.

Kaoko Metals has expanded drilling at its Chalkos Copper-Silver Project to at least 15,000 metres after encouraging early observations at Otniel and a new surface copper discovery at Donkey Hill East. A second rig is now drilling Donkey Hill, while assays from the first two Otniel holes are expected within two to three weeks.
