Latest Resource Conversion News

Maronan Metals has reported broad and high-grade silver-lead intersections from its ongoing 40,000-metre infill program, including 11 metres at 10.3% lead and 116g/t silver. More than 15,000 metres have now been completed, with results feeding a planned 2027 resource update and pre-feasibility study.

Orezone Gold has outlined a 14-year plan for its newly acquired Casa Berardi mine, targeting 1.63 million ounces of production and an after-tax NPV of US$1.05 billion. The economics are substantial, but the plan remains a preliminary assessment built partly on Inferred Resources and requires significant capital and permitting work.

Astral Resources has reported broad and high-grade gold intersections from two deep holes at Theia, including 22 metres at 2.73g/t and 2 metres at 12.8g/t. The results extend the evidence for mineralisation below the current resource shell, but any resource increase remains dependent on the six remaining holes and further interpretation.

Aureka Resources has reported high-grade gold mineralisation beyond the current inferred resource at its Irvine project in Victoria, including a 4.74g/t intercept at depth and the first significant results from a 2km gap between established lodes. The results expand the exploration story, but remain early-stage drilling data with further assays pending.

Charger Metals has mobilised an RC rig for a 10,000m programme aimed at expanding and upgrading confidence in its 10.6Mt Medcalf lithium resource. The work is funded by the $3.752 million cash sale of the Bynoe Lithium Project and comes as Charger commits to a scoping study at Lake Johnston.

Alkane Resources has lifted group Ore Reserves to 1.374 million ounces after exploration and resource conversion replaced depletion across its operating portfolio. The FY26 update also puts Björkdal’s open-pit restart and Costerfield’s extended mine life into sharper focus.

Black Cat Syndicate has extended gold mineralisation beyond the current resource boundary at Trojan after completing a 56-hole, 6,804-metre RC drilling program. The results support further drilling and a potential resource upgrade, although the new intercepts are exploration results rather than an updated Mineral Resource.

Ora Banda Mining has begun underground development at Waihi in Western Australia, where drilling has returned intersections of up to 1.6 metres at 65.9 g/t gold. The mine is scheduled to deliver first underground ore in mid-2027, ahead of the company’s planned 3.0 Mtpa Davyhurst processing plant.

Rox Resources has started surface diamond drilling at Youanmi, targeting resource conversion, incremental growth and deeper extensions of the high-grade United North system. The campaign could support future reserve growth and mine-life extensions, but its value still depends on drilling results that have yet to arrive.

Maronan Metals has intersected repeated copper-gold zones north of its 2025 Indicated resource at the Maronan Project, including a 20-metre interval grading 0.83% copper and 0.42g/t gold. The results support ongoing resource growth work, but further drilling and assays are needed before any resource change can be established.

Brightstar Resources has unveiled spectacular high-grade gold intercepts at its Bull Oak deposit, including a standout 7 metres at 119g/t Au, as it ramps up efforts for a Pre-Feasibility Study on its Sandstone Gold Project.

Santana Minerals has reported further high-grade gold intercepts from infill drilling at its Rise and Shine South deposit, enhancing the size and grade consistency of the high-grade core and revealing promising deeper mineralisation.
