Latest Grade Control Drilling News

Forrestania Resources has outlined a maiden 223,300-ounce JORC Mineral Resource at Tampia, a previously mined deposit positioned 140km from the Edna May processing plant. The estimate gives the newly acquired Westonia Hub another potential ore source, but relies on an AUD 6,000/oz gold price assumption and includes 104,800 ounces classified as Inferred.

Redcastle Resources reached its biggest operational milestone in FY2026 by starting mining at Redcastle Reef, but the project was temporarily suspended after Wiluna Mining halted relevant processing activities. The annual report also flags a material uncertainty over the company’s ability to continue as a going concern.

Minerals 260 has emerged from FY26 with a 6.2Moz Bullabulling resource, a maiden 2.5Moz reserve and a pre-feasibility study pointing to a 19-year gold operation. The project is now moving into definitive feasibility, but debt funding, approvals and a final investment decision remain ahead.

Andromeda Metals completed key early works at its Great White kaolin project and achieved 99.9986% HPA purity at pilot scale. But a $98.9 million impairment, $3.2 million cash balance and material going-concern uncertainty leave funding as the decisive hurdle.

Redcastle Resources has quantified 6,600 ounces of gold already mined and sitting on its ROM pad, but the inventory remains a Mineral Resource rather than an Ore Reserve. The stockpiles are ready to move, although processing arrangements are still being negotiated and mining is currently suspended.

Maritana Minerals has extended gold mineralisation beneath the planned Pit 4 floor at Boorara, with drilling still open at depth. The results could feed a larger resource and revised pit design, although assays, estimation and optimisation work remain ahead of a targeted mid-2027 restart.

Auric Mining has reported a 4-metre intersection grading 10.49 grams per tonne gold west of its planned Munda open pit, alongside a series of high-grade near-surface results inside the Stage 2 design. The results arrive as pit engineering and Ore Reserve work move towards an expected October release ahead of a planned 2027 mining restart.

Resources & Energy Group has reported strong gold intercepts from grade control drilling at its Maranoa project in Western Australia, including 2 metres at 15.84g/t and 4 metres at 10.38g/t. The results support further mine-planning work, but do not yet change the deposit’s existing inferred resource.

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.

Catalyst Metals has lifted the Keillor gold Resource from 81koz to 307koz after a major drilling campaign, while the operating mine ramps up near the Plutonic processing plant. The company expects an Ore Reserve update to extend Keillor’s initial three-year mine life.

Rox Resources has increased Youanmi’s Ore Reserve by 8% to 727,000 ounces after mining depletion, while the broader Mineral Resource edged up to 2.195 million ounces. The update excludes results from recent surface and underground drilling programs, leaving future revisions as a potential source of change.

Redcastle Resources has reported robust new gold assay results from its Queen Alexandra grade-control drilling, reinforcing the deposit's potential and underpinning plans for pit expansion into a newly granted mining lease.
