Latest Cost Estimation News

Ballard Mining is seeking up to A$50 million to fund aggressive drilling, early infrastructure and feasibility work at its Mt Ida Gold Project. The raise gives the developer a larger runway towards a mid-2027 development decision, but comes with dilution and no guarantee the full amount will be secured.

Axel REE is moving its Caladão rare earths project into the next technical test: exploratory in-situ recovery work at the Woolrich deposit. The company says bench-scale testing has recovered up to 560ppm soluble TREO, but field performance, groundwater behaviour and project economics remain unproven.

Renascor has produced battery-grade purified spherical graphite at demonstration scale, achieving 99.97% carbon purity through its hydrofluoric acid-free process. The result strengthens the commercialisation case, but Siviour graphite trials, customer qualification and project financing are still ahead.

EcoGraf has replaced its earlier Epanko announcement after ASX correspondence, setting out the assumptions behind a potential increase in Stage 1 production to 87,600 tonnes per annum. The higher-throughput case lowers estimated unit costs, but remains preliminary and is not yet the basis for project financing or a final investment decision.

Tolu Minerals has set out a Q1 2027 restart target for its Tolukuma gold-silver mine in Papua New Guinea, backed by a recently upgraded 909,000-ounce resource and refurbishment of an existing processing plant. The company says it has sufficient funding to reach production, but the timetable remains dependent on mine development, plant work and operating execution.

Pursuit Minerals posted an A$666,579 FY2026 profit, but the result was driven largely by a fair-value gain on its Kendrick Resources investment rather than operating revenue. The company’s more consequential development is in Argentina, where Rio Grande Sur now carries a 1.264 million tonne LCE resource, a maiden probable reserve and a pre-feasibility case for 5,000 tonnes per year of lithium carbonate.

Adavale Resources is presenting its 610-square-kilometre Parkes Gold Project as a belt-scale opportunity with 383,300 ounces of reported gold resources and existing processing infrastructure. The next test is whether metallurgical work, a scoping study and funding can turn that inventory into a credible development plan.

Altamin has completed the core technical work for its Lazio geothermal brine Scoping Study, but auditors have flagged material uncertainty over the company’s ability to continue as a going concern. The ASX-listed developer ended FY2026 with A$2.39 million in cash after raising A$5.39 million during the year.

PTR Minerals has posted a 463 million tonne maiden resource for its Rosewood titanium project, backed by strong early processing results and fresh funding. The next test is whether the large geological inventory can become an economically viable mine.

Temas Resources and SAGA Metals have begun an eight-week optimisation program aimed at turning strong laboratory recoveries into a defined processing flowsheet and first high-purity titanium, vanadium and iron products. A successful stage could lead to a C$650,000-C$750,000 mini-pilot, although that funding remains subject to technical results and SAGA approval.

Cobalt Blue has secured a US$150,000 contract to deliver key technical work for Glomar Minerals’ planned US polymetallic nodule refinery. The work takes Project Infinity into a formal Preliminary Economic Analysis, although the project remains at an early evaluation stage and its cost estimates carry a wide accuracy range.

Australian Vanadium reported progress across its mine, electrolyte and battery businesses, but auditors highlighted material uncertainty over the company’s ability to continue as a going concern. The group held $17.9 million in cash at 30 June, yet expects to need additional funding within 12 months.
