Latest Copper Mineralisation News

Estrella Resources has expanded its Timor-Leste exploration footprint by 100km2 while securing conditional approval to export a 100-tonne manganese sample to an Indonesian customer. The company is also preparing 3,000 metres of drilling and a possible upgrade to part of its 621Mt Werumata limestone resource.

Hancock Prospecting has agreed to invest A$8.77 million in White Cliff Minerals for a proposed 13.5% stake, giving the junior explorer fresh capital to accelerate drilling at its Rae Copper Project in Nunavut. The placement still requires shareholder approval.

Sarytogan Graphite has intersected 318 metres of copper mineralisation from surface at its Ilksan prospect in central Kazakhstan, including a higher-grade 15.2-metre zone grading 0.40% copper. The result extends the system identified in an earlier hole, with assays from a deeper 452-metre hole due in the coming weeks.

Raptor Metals has identified two conductive systems across its Chester copper project, including the strongest off-hole response recorded near a high-grade drill intersection. The results give the company specific targets for follow-up drilling, but the conductors remain exploration targets rather than a resource estimate.

GreenTech Metals has returned its strongest multi-metre copper result to date at the Ayshia deposit, with gold, silver and zinc credits included. The intersection sits approximately 65 metres beyond the existing resource envelope, although its true width remains unconfirmed.

Rumble Resources is preparing three drilling campaigns across Western Australia while an updated Western Queen study approaches its expected late-September release. The programs target resource growth at Wardawarra and Munarra Gully, alongside previously identified gold systems at Thunderstorm.

Voltaic Strategic Resources has identified malachite-rich copper mineralisation across an approximately 100-metre area at its El Dinero prospect in Western Australia. Preliminary pXRF readings reached an average 8.31% copper in one selected sample, although laboratory assays are needed before the results can be treated as representative.

Maronan Metals has intersected repeated copper-gold zones north of its 2025 Indicated resource at the Maronan Project, including a 20-metre interval grading 0.83% copper and 0.42g/t gold. The results support ongoing resource growth work, but further drilling and assays are needed before any resource change can be established.

Kaoko Metals secures $20 million from institutional investors to ramp up diamond drilling and exploration across its Namibian copper-silver and gold-copper-tungsten projects.

Koonenberry Gold has identified compelling drill-ready copper and gold targets at its Wilga Flats Project near Evolution Mining’s Cowal Gold Mine, with drilling set to begin after Dunedoo operations conclude.

Javelin Minerals has launched a significant diamond drilling campaign targeting two major deep gold-copper anomalies at its Coogee Project in WA, supported by WA Government funding.

AusQuest’s latest diamond drilling at the Cangallo project in Peru pushes copper mineralisation down to at least 800 metres and reveals multiple higher-grade zones, reinforcing the scale of this emerging porphyry system.
