Latest Copper Exploration News

Eagle Mountain Mining has formalised a joint venture with Nittetsu Mining for the Oracle Ridge copper project in Arizona, with Nittetsu committing US$20 million to advance exploration and development while managing the operation.

Renegade Exploration has divested its 22% interest in the Carpentaria Joint Venture to True North Copper for $2.88 million, opting for a mix of cash, shares, and performance rights to maintain exposure to the project’s upside while refocusing on North American assets.

Aruma Resources has kicked off its maiden diamond drilling campaign at the Tillex Copper-Silver Project in Ontario, aiming to expand the known high-grade copper mineralisation and deliver a substantial resource estimate.

Hawk Resources has reported high-grade copper mineralisation near surface at its Cactus project in Utah, with spot pXRF assays peaking at 37.3% copper over potentially wide intervals. The ongoing drilling campaign aims to delineate a shallow mineralised zone along a historically mined corridor.

Western Mines Group has streamlined its exploration portfolio by divesting non-core tenements and acquiring two promising greenfield nickel-copper sulphide projects along the Yilgarn Craton margins, aligning with its magmatic sulphide expertise.

Midas Minerals has raised $28 million through a heavily supported placement to fund expanded drilling and feasibility studies at its Otavi project in Namibia. The capital boost lifts the company’s cash reserves to approximately $33 million, underpinning an aggressive exploration push.

Triton Minerals’ maiden drilling at Mozambique’s Aucu Project has validated gold mineralisation across multiple targets, revealing a polymetallic hydrothermal system with notable copper anomalism. The early-stage results set a clear path for systematic follow-up exploration.

MinRex Resources has finalized its merger with Electrum Discovery, creating a well-funded ASX-listed explorer with advanced gold and copper projects in Serbia and Australia. The deal brings Electrum’s Tlamino Gold Project and Timok East Copper-Gold targets into MinRex’s portfolio, alongside its existing Sofala Gold Project in New South Wales.

Midas Minerals has reported a substantial 52m mineralised intercept at its Spaatzu Prospect in Namibia, highlighting widespread high-grade copper and silver mineralisation and advancing its Otavi Copper Project exploration.

Belararox Limited has launched a >1,000 km² airborne electromagnetic survey over its Kalahari Copper Project in Botswana, aiming to unlock new copper targets near MMG’s expanding Khoemacau hub. Diamond drilling is planned for May to follow up on promising geophysical anomalies.

White Cliff Minerals has announced metallurgical test results from its Danvers deposit in Nunavut, Canada, showing copper recoveries exceeding 95% and high-grade concentrates produced via conventional flotation without regrinding. These findings support a lower-cost, scalable processing route and coincide with ongoing exploration along the Teshierpi Fault Zone.

PolarX Limited has reported exceptional high-grade copper assay results from its 2025 drilling at the Caribou Dome Copper Project in Alaska, with plans for a substantial 10,500m drilling campaign commencing in June 2026.
