Mammoth Minerals expanded its Nevada exploration portfolio and drilled more than 21,000 metres at the Buster Trend, but its FY2026 report also highlights a material uncertainty over its ability to continue as a going concern. The company posted a larger loss and remains dependent on future equity funding to sustain exploration.

Manhattan Gold Corporation (ASX:MHC) has emerged from a transformational year with encouraging Hook Lake drilling, expanded tenure and a sharper gold focus, but no compliant resource yet and only A$2.01 million in year-end cash. The company reported an A$8.90 million loss after absorbing exploration costs and a large loss on its lithium divestment.

Cobalt Blue has secured a US$150,000 contract to deliver key technical work for Glomar Minerals’ planned US polymetallic nodule refinery. The work takes Project Infinity into a formal Preliminary Economic Analysis, although the project remains at an early evaluation stage and its cost estimates carry a wide accuracy range.

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.

Aruma Resources’ 2026 annual report puts the Tillex Copper-Silver Project at the centre of its strategy after wide, high-grade drilling results in Ontario. But the explorer also reported a $2.71 million loss, $788,658 in cash and a material going-concern uncertainty dependent on further capital.

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.

Cobalt Blue has cleared important technical and regulatory hurdles at its Kwinana refinery, but the pre-revenue developer says further funding is needed and auditors flagged material uncertainty over its ability to continue as a going concern. The company reported an A$8.797 million loss for FY2026 despite ending the year with A$4.265 million in cash.

Ballymore Resources has extended high-grade silver-lead-zinc-indium mineralisation closer to surface at its Torpy’s discovery in North Queensland. The latest drilling supports a multiple-shoot interpretation, but the project remains at an early exploration stage with assays pending and no Mineral Resource defined.

Sierra Nevada Gold has begun mobilising a five-rig, 25,000m exploration campaign at its As Safra Copper-Gold Project in Saudi Arabia. The program will test Central Copper’s resource potential while opening up more than 12km of broader discovery targets, with first assays expected in November 2026.

Australian Gold and Copper has reported repeated broad zinc-gold-lead intersections at northern Evergreen, including a peak interval of 26.4% zinc. A 21-hole, 2,593-metre RC program has also finished testing extensions to the prospect’s recent high-grade gold-silver discovery, with assays due from late October to early November.

Orbit Resources enters FY2027 with a 17.52Mt Lewis Ponds resource, a preliminary study pointing to a A$481 million pre-tax NPV and a new polymetallic sulphide discovery outside the existing resource. The gains come with familiar junior-miner constraints: a A$3.49 million annual loss, A$3.69 million in cash and further funding still required.

QMines has reported a broad 44-metre copper intersection and high-grade zinc-lead-gold-silver mineralisation from six holes at Mt Chalmers. The results support ongoing Definitive Feasibility Study work, while a hole ending in copper mineralisation and upcoming barge drilling add further exploration interest.
