Latest Copper Exploration News

Sunstone Metals has expanded its Bramaderos gold-equivalent resource to 3.6Moz and reported new Porotillo and Copete discoveries, but its FY2026 accounts carry a material uncertainty over going concern. A post-year-end A$9.94 million placement has improved liquidity, although further equity funding remains central to the exploration plan.

Mandrake Resources has secured the final regulatory approval for a planned 3,200-metre gold-copper drilling programme at its Berinka project in the Northern Territory. Mobilisation is scheduled for October, putting the company’s next exploration milestone within reach.

Empire Resources has identified four magnetic anomalies and prioritised two for drilling at its renamed Bradley Well project in Western Australia. Historical copper intercepts provide geological clues, but the targets remain untested and drilling timing depends on rig availability.

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.

Raptor Metals has sold its remaining Australian Gold and Copper stake for approximately $468,200, converting a legacy asset into cash without issuing new shares. The proceeds add funding flexibility as the company advances copper exploration in New Brunswick.

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.

Broken Hill Gold has started a 48 line-kilometre induced polarisation survey and 670 line-kilometre magnetic program at White Dam, targeting sulphide mineralisation beneath existing oxide prospects. A second diamond rig is also mobilising, but the next value test remains firmly in the ground: geophysical anomalies must translate into drilling results and an upgraded resource.

Evolution Energy Minerals has moved its Chikundo Copper Project from surface exploration to subsurface testing, with a 3,350-metre reverse circulation campaign now underway in southern Tanzania. The programme will first target the Malachite Pit and main Chikundo anomaly before optional holes assess three additional prospects.

TechGen Metals has outlined a funded exploration campaign spanning gold, copper and silver targets, with about A$3 million in pro forma cash and several assays due through late 2026. The strongest potential catalyst is John Bull, where step-out drilling could support a maiden Mineral Resource Estimate if results are positive.

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.

Kincora Copper has received a further US$1.5 million from the staged sale of its Mongolian subsidiaries, taking proceeds to US$6.5 million. A final US$3.5 million remains scheduled by the end of 2026, subject to transaction milestones and conditions.
