True North Copper says its Cloncurry Copper Project has reached a more substantial technical base, with Wallace North flotation tests averaging 88.9% copper recovery and contained copper-equivalent Resources rising 62% to 204kt. The pre-feasibility study remains targeted for completion in late 2026, but gold recovery, toll-processing terms and economic outcomes are still unresolved.

TMK Energy has secured Mongolian regulatory acceptance for a formal gas discovery at its Gurvantes XXXV Pilot Well Project, opening the next stage toward appraisal, reserves and a potential production licence. The milestone starts a 90-day window for an appraisal program, but no reserves or commercial production figures have yet been established.

Brazilian Rare Earths has strengthened the development case for its Brazilian rare earths portfolio, reporting high-grade Monte Alto drilling, a new Sulista discovery and first concentrate production at Camaçari. The company ended September with A$121.8 million in cash and no borrowings, although its headline US$6.0 billion project valuation remains based on a preliminary study with substantial inferred resources.

Kali Metals has expanded its Marble Bar gold pipeline after reporting shallow high-grade drilling and nine additional targets identified after quarter end. The explorer also ended September with $5.242 million in cash and a binding agreement for up to $700,000 of JX Advanced Metals-funded exploration in the Southern Lachlan Fold Belt.

Aurum Resources has reported gold mineralisation outside the current resource at BST1 and BMT2, including a 57-metre intercept grading 2.34 g/t gold. The results will be assessed in an updated Boundiali resource estimate due by the end of October, ahead of a planned definitive feasibility study.

CuFe is seeking to take full ownership of its Tennant Creek copper-gold-bismuth project by issuing 1.6 billion shares to the holders of the remaining 45% interest. The deal could simplify development decisions, but would also leave Gold Valley and its associates with about 53% of CuFe if completed.

Regener8 Resources has completed the sale of its Kookynie Gold Project to Goldarc Resources for initial consideration of A$1.5 million in escrowed shares, with up to a further A$1 million tied to future resource milestones. The deal leaves Regener8 focused on its Srebrenica North silver-zinc-lead-antimony project in Bosnia and Herzegovina.

G50 has extended the known strike of its Golconda gold-silver system to more than 1.8km, with shallow high-grade results from the Golden Eagle target. The ASX-listed explorer also finished the quarter with A$25.778 million in cash after a placement backed by Hancock Prospecting.

Alkane Resources has extended the known gold-antimony system beneath Nagambie’s West Pit, with drilling identifying mineralisation outside the existing Inferred Resource. The results strengthen the exploration case, but do not yet change the resource estimate or establish an economic mine plan.

OD6 Metals has extended the high-grade fluorspar footprint at its Quinn project in Nevada, with rock-chip assays reaching 95.6% CaF₂ along a 350-metre trend from Blue Bell to Shannon Queen. The result elevates the corridor to a priority exploration target, although drilling is still needed to establish continuity, depth and scale.

Rapid Critical Metals has reported its highest silver grade to date at the Webbs project, alongside extensions beyond the existing resource outline and a decision to add a fourth drill rig. The results strengthen the exploration story, but the intercepts remain down-hole results requiring further drilling and modelling.

BHP has held its FY27 production and unit-cost guidance despite a 19% year-on-year fall in first-quarter copper production, with stronger iron ore and coal output providing some balance. The mining giant also reported a 10.73 billion tonne Olympic Dam block cave Mineral Resource, although the new resource remains far from an Ore Reserve or approved mine plan.
