Latest Copper Exploration News

Canterbury Resources has reported a broad copper-molybdenum intercept at Briggs while early core observations suggest its John Hill deposit may extend beyond the current resource boundary. The results support ongoing resource upgrades and feasibility work, but John Hill assays are still pending.

BOA Resources has returned high-grade copper intersections from all six initial RC holes at Ricci Lee, including 14 metres at 2.49% copper and 15 metres at 2.25%. Assays from 40 further RC holes and 92 aircore holes across five other prospects remain pending.

White Cliff Minerals has reported broad, bornite-dominant mineralisation in the first-ever drilling at Bornite Hills, but laboratory assays are still weeks away. The discovery adds a new target to the Rae Copper Project, alongside a sediment-hosted copper horizon now traced across a much larger area.

Cobre has logged copper sulphide mineralisation in its first deep diamond hole at Sierra Atacama since 2021, extending the system below the existing operation. The result is encouraging but remains visual and preliminary, with laboratory assays due in October.

Prospect Resources has expanded drilling at Nyungu Central after returning a 27-metre copper intercept outside the existing resource, while maiden drilling at Sharamba confirms a new copper discovery. The results add momentum to Mumbezhi’s growth story, but most Phase 3 assays remain outstanding and no resource update has yet been made.

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.

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.

Midas Minerals has returned a high-grade 10.9-metre copper intercept at its Deblin deposit in Namibia, including 5.7 metres at 8.85% copper. The results strengthen the case for continued resource drilling, although Deblin has yet to receive a mineral resource estimate.

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.

Culpeo Minerals has started a four-hole, 2,000-metre maiden diamond drilling programme at Vista Montana, testing a copper-molybdenum target north-east of its Lana Corina discovery. The company is also using IP surveys to refine targets, while assays from El Quillay South returned several narrow copper-gold intersections.

Middle Island Resources has unveiled substantial copper anomalies at its Jelaca and Oglavak prospects within the Priboj Project, bolstering its volcanogenic massive sulphide exploration thesis.
