Latest Mine Planning News

Latitude 66’s KSB project has returned a striking preliminary economic case, with a post-tax NPV8 of US$485 million and an 85% IRR at a US$3,500 per ounce gold price. The opportunity remains unbuilt, unfunded and subject to further study, permitting and a production target containing 10% Inferred Resources.

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.

Aeris Resources delivered FY26 production within guidance while building a much larger investment program around Tritton, including the Constellation and Mallee Bull developments. The company enters FY27 with no debt, $202 million in cash and receivables, and a sharper test of whether higher spending can convert expanded resources into longer mine life and production.

VHM has taken Goschen from a permitted project to a more financeable development, with Iluka committing to buy all planned rare earth concentrate and providing A$40 million in convertible note funding. The company remains pre-revenue, has not made a Final Investment Decision and will need further funding before construction can begin.

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.

Rua Gold has reported its highest-grade Auld Creek drilling results to date, including 0.6 metres at 136.2 g/t gold equivalent and 2.9 metres at 38.8 g/t gold equivalent. The company has completed 19,600 metres of resource drilling and is targeting an updated resource, approvals application and pre-feasibility study before year-end.

Osmond Resources reported a A$7.61 million FY26 loss and warned of a material uncertainty over its ability to continue as a going concern, despite holding A$5.50 million in cash. The company is betting its Spanish Orión project can move from exploration into a resource estimate and scoping study in the coming months.

Astral Resources has reported a 1.54g/t Au weighted average across 41 infill holes at Theia, including several high-grade intervals that exceed the existing Stage 1 resource grade. A separate deviated hole returned 1m at 219g/t Au, adding further support to the early mining inventory while deeper drilling continues.

Kingston Resources says infill drilling at Jack’s Hut has confirmed the location and continuity of polymetallic mineralisation targeted for potential underground mining at Mineral Hill. The results will feed into a resource update, while surface drilling in October will test extensions beyond the current resource.

Black Cat Syndicate has appointed mining veteran Chris Stone as Acting Managing Director, with the interim arrangement beginning immediately and running indefinitely. Stone will earn $600,000 a year plus superannuation while the company searches for a permanent appointment.

Sun Silver has intersected silver-gold mineralisation from surface at its Maverick Silver Project in Nevada, including a higher-grade 1.5-metre zone grading 75 g/t AgEq. The results also extend the project’s antimony story and could influence future mine sequencing studies, although the shallow mineralisation remains only lightly tested.
