Latest Mine Planning News

American Rare Earths has expanded the proposed Cowboy State Mine in Wyoming to a 4.5 million tonne per year operation with a 26-year mine plan and an estimated after-tax NPV of US$1.07 billion. The stronger study case comes with higher capital, lower recoveries and no Ore Reserves, leaving metallurgy, permitting and funding as the next tests.

Silver Mines has built a substantially larger economic case for Bowdens, but the project still needs NSW approval before its 93.5 million ounce reserve can become a mine. The company is now funding the next phase with a A$70 million placement while absorbing dilution and a major royalty buy-back.

Accelerate Resources enters FY2027 with high-grade manganese targets at Woodie Woodie North and new gold zones at Balagundi, but a sharp annual loss and ongoing funding needs remain part of the story. The company plans maiden and follow-up drilling while seeking shareholder approval to rename itself Mango Metals.

Forrestania Resources has lifted the higher-confidence portion of its Lady Ada and Lady Magdalene gold resource by 43%, even as total contained ounces fall 4% to 285,700 ounces. The update strengthens the development case, but most of the resource remains Inferred and the tenements are subject to ongoing legal proceedings.

Odyssey Gold has secured a native vegetation clearing permit and a new mining lease at Tuckanarra, while refurbishment work at the planned Kirkalocka processing facility moves ahead. The first toll milling parcel is targeted for June 2027, but a required joint venture agreement remains unresolved.

Jupiter Mines delivered above-target production and sales at its Tshipi manganese mine in FY26, but higher costs and a stronger South African rand pulled group profit lower. The year also brought a new majority co-investor, a leadership transition and fresh questions around the mine’s resource and reserve base.

Barton Gold has moved deeper into development after raising $40.9 million, completing its largest-ever drilling campaign and ending FY2026 with $31.9 million in cash. The progress came alongside a $22.4 million loss as spending accelerated across Tunkillia, Challenger, Tolmer and Wudinna.

Osmond Resources has outlined a 60.0 million tonne maiden JORC resource at its Orión critical minerals project in Spain, but most of the inventory remains Inferred and unproven economically. The company will resume drilling in October, with an updated estimate targeted for the first quarter of 2027.

Atomic Eagle has begun a technical review aimed at determining whether its 60%-owned Madaouela uranium project in Niger can support a materially larger development than outlined in the 2022 feasibility study. The company is targeting a JORC-compliant resource in Q4 2026 and a scoping study in Q1 2027.

White Cliff Minerals has expanded its Rae Copper-Silver Project into a multi-kilometre copper system, with a peak interval of 21.1% copper and recoveries reaching 95.4%. The exploration progress came alongside an A$18.8 million FY26 loss, A$14.5 million operating cash outflow and an auditor-highlighted material uncertainty over going concern.

Aureka’s inferred gold resources climbed to 454.8koz in FY2026 as the company moved closer to production through a proposed acquisition of the Fiddlers Creek mine and Wedderburn mill. The shift comes with a $5.75 million annual loss, $5.97 million operating cash outflow and further equity funding.

Minerals Exploration has pivoted decisively into New Zealand gold and tungsten, but its annual report carries a material going-concern warning after a $2.66 million loss and $949,097 operating cash outflow. Exploration has produced encouraging surface samples and broad gold zones, though no mineral resource has been established.
