Latest Copper Mineralisation News

Red Mountain Mining has completed its maiden 1,776-metre drill program at Oaky Creek, with antimony-gold assays due in November. In Montana, surface sampling confirmed tungsten mineralisation across three Pioneer prospects, while the company ended the quarter with A$1.022 million in cash and an estimated 2.2 quarters of funding.

Rubix Resources has reported encouraging copper exploration signals at Paperbark and stronger prospectivity at Redbeds, but ended the September quarter with just A$6,000 in cash. The company estimates it has 0.05 quarters of funding available and says it will need to raise more capital to continue operations.

True North Copper has extended Mt Oxide’s exploration story and lifted Cloncurry’s contained resource to 204kt CuEq, while an $18.75 million equity raise helps fund its next phase. The quarter also highlights the company’s continuing dependence on capital markets, with reported cash covering less than two quarters of current outgoings.

Taiton Resources has added a farm-in tenement and applied for more ground at its Challenger West gold-copper project, backed by historical high-grade results. The expansion comes as cash falls to $294,000 and directors and the CFO move to half pay to preserve funds.

Mantle Minerals is changing the geological model at Carlton Hill, moving away from shallow stratiform targets towards potentially structurally controlled zinc-lead and copper mineralisation. The explorer ended September with A$5.232 million in cash and says its current spending rate represents 31.59 quarters of funding.

Kaoko Metals has expanded its Chalkos exploration campaign to at least 15,000 metres after maiden drilling confirmed broad, shallow copper-silver mineralisation at Otniel. A $20 million placement leaves the ASX-listed explorer with $22.0 million in cash to fund the next phase, but the discovery remains at an early exploration stage.

Prospect Resources has extended copper mineralisation beyond the existing Nyungu Central resource and identified a new copper-bearing system at Sharamba in Zambia. The explorer ended the September quarter with A$33.93 million in cash and term deposits, while its Mumbezhi Scoping Study remains targeted for Q1 2027.

Red Hill Minerals collected A$6.0 million from its Onslow Iron royalty in the September quarter while maintaining A$58.7 million in cash after paying a fully franked dividend. Exploration also advanced across copper, gold and base metals, although several results remain early-stage and require further drilling.

Tarrina Resources has expanded the exploration case for both its NSW gold project and South Australian copper-gold project, with six Christmas Gift holes intersecting gold and Walparuta work defining 23 drill targets. The company ended the quarter with $1.72 million in cash, but Walparuta drilling remains dependent on approvals and native title negotiations.

AusQuest’s Cangallo copper-gold discovery has been declared a Project of National Interest by the Peruvian Government, strengthening surface-rights protection and project security for the next four years. The designation arrives as the company prepares a 20-pad drilling campaign and seeks approval for another 20 pads in 2027.

White Cliff Minerals has expanded copper mineralisation at Danvers to 4.75km, added a new Bornite Hills discovery and secured A$8.77 million from Hancock Prospecting. The funding improves the immediate exploration position, but the project remains at the drilling and assay stage.

E79 Gold is preparing to start more than 12,000 metres of drilling at its Cue Gold Project in November, subject to final heritage clearance. The explorer ended September with $1.946 million in cash as it moves from target generation to field testing.
