Latest Mine Planning News

Nexus Minerals has more than doubled its Wallbrook Mineral Resource to 631,000 ounces, lifting group resources to 709,000 ounces across Western Australian projects. The expansion comes alongside a $6.53 million FY2026 loss, falling cash reserves and a post-year-end $5.4 million capital raising.

Lake Resources has reduced Kachi’s estimated capital cost by US$220 million and outlined a 25-year, 25,000-tonne-per-year operation. But the lithium developer still needs further funding, environmental approval, offtake and a final investment decision before construction can begin.

Investigator Silver has begun a fully funded 30,000-metre drilling campaign at its Paris Silver Project in South Australia, targeting resource growth and extensions beyond the current mine plan. Assay results will arrive progressively, making the next few months a test of whether recent high-grade hits can translate into a larger, higher-confidence mineral inventory.

Australian Mines has appointed a specialist consultant team to complete the pre-feasibility study for its Flemington Scandium Project, targeting delivery in the first quarter of 2027. The study will retain a 60-tonne-per-year scandium oxide reference case while testing production scenarios of up to 180 tonnes per year.

Perpetual Resources has added 62 lode claims around its Nevada Scheelite tungsten project, expanding the land position by 1,271.63 acres and more than 15 times the original patented claim area. The move broadens the project from a historic mine redevelopment opportunity into a larger exploration play, although the new ground remains untested.

Horizon Gold’s annual report presents Gum Creek as a potential 880,000-ounce gold operation, but flags a material uncertainty over its ability to continue without further funding. The company is targeting a Final Investment Decision in Q2 2027 and first gold in the second half of 2028.

Castile Resources has emerged from FY2026 with a larger Rover 1 resource, stronger preliminary project economics and A$9.37 million in cash. The next challenge is converting a A$1.07 billion pre-tax NPV8 study into a funded, permitted mining project.

Delta Lithium reported a $13.2 million FY2026 profit after separating its gold assets into Ballard Mining, while advancing lithium projects at Mt Ida and Yinnetharra. The result was supported heavily by demerger-related accounting gains, leaving the next test firmly operational: whether the projects can move towards production.

Narryer Metals is buying the Redhill Copper Project in southern Chile from 29Metals, gaining an existing 4.3Mt inferred resource and a much larger conceptual exploration target. The deal also brings a A$1 million strategic investment from 29Metals at a 54% premium to Narryer’s pre-announcement share price.

Alma Metals has intersected 383.8 metres at 0.25% copper from just 10.2 metres at its Briggs project, including a higher-grade 76.7-metre zone at 0.34%. The result supports the company’s effort to upgrade parts of the resource ahead of a pre-feasibility study, although the intersection remains a downhole measurement and ended in mineralisation.

Five of nine diamond holes at Minrex's Barje deposit have returned the widest and highest-grade intersections drilled there, challenging the historical model of a low-grade central corridor. The results arrive ahead of a maiden JORC resource estimate planned for next quarter.

Rox Resources is pitching Youanmi as a fully funded, near-term gold producer while outlining an ambition to lift output beyond 150,000 ounces a year. The mine’s initial plan remains materially smaller, with first gold targeted for mid-2027 and average production of about 117,000 ounces a year.
