Latest Feasibility Study News

Delorean Corporation and Opal have completed the concept stage for a proposed anaerobic digestion facility at Opal’s Maryvale Mill in Victoria. The project could replace natural gas used by the mill’s rotary lime kiln, but still requires further engineering, commercial work and a final investment decision.

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.

Astron Limited (ASX:ATR) says its Donald rare earths and mineral sands project is construction-ready, with a $759 million Phase 1 pre-tax NPV and first production targeted for 2028. The unresolved question is whether debt financing can convert the project’s strong study economics into a final investment decision.

Ballard Mining has lifted the Mt Ida Gold Project’s global Mineral Resource Estimate by 56% to 1.84 million ounces, led by a larger Baldock deposit and new regional resources. The increase gives the planned feasibility study a much larger technical base, although most of the resource remains Inferred and is not yet an Ore Reserve.

Global Gold Mining has reported recoveries of up to 91.4% from metallurgical tests at its Sturec gold deposit in Slovakia, providing a useful processing input for the project’s pre-feasibility study. The result is encouraging, but the weaker 79.5% recovery from transitional material and the laboratory-scale nature of the work remain important qualifications.

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.

Black Canyon has spent the 2026 financial year moving Wandanya from discovery towards resource definition, backed by 17,200 metres of drilling and encouraging manganese beneficiation results. The exploration company ended the year with $7.77 million in cash and no debt, but remains reliant on future funding before any development decision can be made.

PC Gold’s Spring Hill project emerged from FY2026 with a sharply larger resource, fresh institutional funding and a clearer path towards feasibility studies. The gold explorer remains pre-production and loss-making, but its post-year-end A$75 million raise gives it substantial room to expand drilling and development work.

Latrobe Magnesium has secured A$8.5 million in equity funding to complete its Latrobe Valley demonstration plant and advance a proposed South Carolina magnesium project. The raising gives the company near-term funding certainty, but also brings further dilution and leaves the larger US development dependent on future capital.

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.

Magnum Mining has completed a 10,000-metre auger programme at its Piracanjuba North ionic adsorption clay rare earths project in Brazil, shifting its focus to a 32.5km² plateau zone. The company is targeting a maiden JORC 2012 Mineral Resource Estimate in November, but the project remains at an early exploration stage with no declared resource or reserve.
