Latest Diamonds News

Metal Hawk has secured $1.2 million from sophisticated investors as RC drilling begins at the Numbat lode in Western Australia. The campaign will test whether the company’s strongest Leinster South gold intercept extends along strike and at depth.

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.

AuKing Mining has reported a 50-metre interval grading 2.03% TREO from surface at its Tundulu rare earths project in Malawi. The result, from drilling about 400 metres west of earlier holes, supports a broader near-surface mineralised footprint but remains exploration-stage evidence.

Megado Minerals has returned a shallow copper-silver intersection from the first hole of its maiden drilling campaign in northern Spain, including 0.25 metres at 1.39% copper and 18g/t silver. Two further holes have been completed but remain unassayed, leaving the broader size and continuity of the mineralisation unresolved.

Olympio Metals has started a roughly 1,500-metre maiden diamond drilling program at its Jacknife silver project in Idaho, targeting mineralisation linked to more than 3.2 million ounces of historical silver production. The campaign is significant, but the company must still verify old data before it can establish a JORC-compliant resource.

Mamba Exploration has confirmed 165 historical copper intersections across a 3km corridor at its 70%-owned Meeka East project, supporting a new felsic volcanic exploration model. The company plans further mapping, geophysics and drilling, although the historical data is not sufficient to define a mineral resource.

Antipa Minerals has extended gold-copper-lead-silver mineralisation across 2.2km at Tim’s Dome, sharpening focus on a large untested electromagnetic conductor. Surface diamond drilling is now underway on the 1.2km target, which remains unproven despite encouraging surrounding assays.

Pursuit Minerals has started its first diamond hole at the Demasía tenement, testing whether lithium-bearing brines extend beyond the existing 1.264 million tonne LCE resource at Rio Grande Sur. Early packer tests recovered brine at shallow depths, but lithium assays are still pending.

Broken Hill Gold has lifted the Vertigo deposit’s Indicated oxide resource by 160% and increased White Dam’s global resource to 118,496 ounces. The company is now testing whether shallow material can support a heap-leach restart while drilling deeper gold-copper sulphide potential.

Gibb River Diamonds reported a A$5.61 million profit after receiving a A$7 million pre-GST distribution from its Neta gold joint venture. The cash windfall leaves the explorer with A$6.74 million in the bank, but its next challenge is converting a one-off mining payment into a credible development pipeline.

Right Resources has begun a fully funded 2,000-metre aircore program at its Blue Prospect near Tumbarumba, testing six tungsten and five gold anomalies for the first time below surface. Assay results are expected progressively during the December Quarter, but the campaign is exploratory and is not designed to define a Mineral Resource.
