Latest Diamond Drilling News

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.

AuKing Mining has reported wide, high-grade rare earth intersections from maiden RC drilling at its Tundulu project in Malawi, including 91 metres at 1.51% TREO. The results also reveal unusually strong heavy rare earth enrichment and have prompted the company to fast-track a maiden resource estimate targeted before the end of 2026.

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.

Rox Resources has reported multiple high-grade underground gold intercepts at Youanmi’s United North area, including 10.30m at 12.46g/t. Ore drives on two levels have also extended about 125m beyond the existing DFS mine plan, with production stoping preparations now underway.

Atlantic Lithium has reported a year of major progress at its Ewoyaa lithium project, including Ghanaian parliamentary approval of its mining lease and a proposed US$210 million takeover by Zhejiang Huayou Cobalt. But the audited accounts also flag material uncertainty over funding if the scheme does not proceed.

North Stawell Minerals has used a conference presentation to position Darlington and Darlington West as its leading tests of the Stawell gold model, while outlining a broader Victorian exploration pipeline. The company stresses that the drilling results and resource figures presented have been previously reported, making follow-up work rather than a fresh discovery the key investor question.

Resolution Minerals has finished its largest-ever exploration program at the Horse Heaven project in Idaho, drilling 42 diamond holes across 12,236 metres. The work sets up a substantial run of gold, tungsten and multi-element assay results, but the completed program has not yet produced new assay data in this announcement.

WhiteRock Lithium has sharply reduced a prospectus accounting adjustment after determining 11.8 million unexercised warrants should not have been remeasured. The correction comes as the newly ASX-listed explorer reports a C$3.19 million after-tax loss and more than C$33 million raised in 2026.

Neometals has cleared a key regulatory hurdle for an A$2 million standby loan from a company controlled by former chairman David Reed. The facility provides near-term funding, but carries 10% interest, security over Barrambie-related assets and potential conversion into equity.

Javelin Minerals is 150 metres into a deep diamond hole aimed at testing an untested magnetic anomaly beneath its Coogee gold-copper resource in Western Australia. No assay results have been reported, but the drilling could clarify whether shallow mineralisation is linked to a larger intrusive system at depth.
