RTG Mining says its Mabilo copper and gold project is moving towards a Final Investment Decision, with Glencore financing up to US$30 million of Stage 1 development. Permitting remains the critical hold-up, while fresh drilling at Chanach has produced no assays yet.

Gold Hydrogen says its Ramsay project has demonstrated helium flow across three wells, with concentrations averaging 15.2% and modelled potential of up to 37 Mscf per well per day. The technical progress comes with a sharper financial constraint: cash fell to A$3.96 million, equal to only 0.57 quarters of reported funding, while a capital raising remains in prospect.

Noronex has completed its Sleitat tin project acquisition and expanded the mapped Alaskan greisen system beyond one kilometre, but the explorer ended September with A$1.135 million and only 1.28 quarters of estimated funding. Assay results, South32-backed drilling and a potential capital raise now sit alongside the company’s exploration ambitions.

Tungsten Mining has moved Watershed into early construction while financing proposals potentially cover about 70% of its A$274 million pre-production capital requirement. The September quarter also delivered a large-scale Mt Mulgine PFS, a A$50 million placement and A$70.1 million in cash.

Vertex Minerals has secured approval for round-the-clock underground operations at its Reward Gold Mine, removing the company’s stated biggest production constraint. The operational opening arrives alongside modest quarterly output, a sharply revised resource and reported cash coverage of less than half a quarter.

Citigold has identified four priority exploration targets at Charters Towers, but no drilling was completed during the September quarter and its reported cash runway fell below half a quarter. The company is also heading into two meetings seeking to replace its board as it pursues funding for the mine restart.

Ark Mines has sharply expanded the reported Sandy Mitchell resource to 379.4Mt, with 97% now classified as Measured and Indicated. Early ANSTO testwork also returned up to 99.6% light rare earth extraction, although the project still faces funding, metallurgical and development hurdles.

Prominence Energy has expanded its South Australian exploration story from a single project to a portfolio with more than 4 Tscf of gross unrisked 2U hydrogen prospective resources. The company is targeting a multi-well drilling campaign in mid-2027, but its A$1.38 million cash balance leaves funding and permitting as important hurdles.

Pure Resources has moved its Garnet Hills strategy from concept towards laboratory validation, with heavy rare earths recovered into solution, CNTF fabrics manufactured in-house and garnet meeting key abrasive standards. The milestones remain early-stage, with no quantified rare earth recovery or commercial revenue reported.

GenusPlus has completed its acquisition of New Zealand telecommunications contractor UCG, extending the group’s communications infrastructure footprint into New Zealand and the Pacific Islands. The upfront consideration was funded from existing cash reserves and a debt facility, but the company has not disclosed the purchase price or expected earnings contribution.

Tesoro Gold has moved El Zorro’s Ternera deposit from a defined resource to a 1.28Moz mineable reserve, while a newly committed A$40 million placement addresses a reported 1.61-quarter cash runway. The next stage is less about proving the orebody and more about completing the DFS, permitting the project and converting funding into development progress.

Iron Bear Resources has retained full ownership of its Canadian iron ore project after Vale declined to advance under their development agreement. The company is now leaning on a completed PFS, a 3.3 billion tonne probable reserve and alternative funding partners to move the project forward.
