Mithril Silver and Gold has lifted the higher-confidence portion of its Copalquin Target 1 resource to 464,000 ounces of gold equivalent, giving the Mexican project a stronger base for mine planning. The upgrade comes alongside a larger loss, substantial exploration spending and an auditor’s warning that further funding is needed to support the company’s going-concern status.

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.

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.

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.

QEM Limited (ASX:QEM) has suspended non-essential work at its Julia Creek vanadium project after metallurgical results undermined the 2024 Scoping Study. The loss-making explorer is now relying on newly acquired Idaho projects, fresh capital and further exploration to justify its next chapter.

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.

Tyranna Resources has signed a binding earn-in agreement covering the 830 km² Coola Rare Earths and Niobium Project in Angola, with two carbonatite-bearing intrusions already mapped. The deal remains conditional on renewal of the project tenement, while a proposed 500 million-option grant adds a significant shareholder-approval question.

Talisman Mining’s Sheepyard prospect has emerged as the company’s clearest exploration opportunity after drilling outlined shallow gold mineralisation across an unconstrained 800-metre strike. But the annual report also shows a shrinking royalty income stream, a $2.705 million loss and fresh reliance on equity funding.

Grand Gulf Energy has reported a sharply wider FY2026 loss after impairing $15.03 million of Red Helium exploration assets. The auditor also flagged material uncertainty over the company’s ability to continue without further capital.

Renegade Exploration has sharpened its portfolio around Nevada and Yukon exploration, with several targets moving towards drilling after high-grade surface results. But the ASX-listed junior ended FY2026 with just $59,869 in cash and an auditor-highlighted material uncertainty over its ability to continue as a going concern.

Greenwing Resources has warned of material uncertainty over its ability to continue as a going concern after reporting a $3.90 million loss for FY2026. The result was hit by a $2.23 million non-cash impairment at its dormant Graphmada graphite mine, while cash remains below near-term project commitments.

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.
