Latest Project Economics News

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.

Cannindah Resources has reported preliminary NovaCell testwork recovering 94% of copper and 92% of silver at a substantially coarser grind, while rejecting 82% of processed material. The results could support a higher-throughput, lower-energy processing route, although gold recovery and concentrate quality still require further work.

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.

Adavale Resources has lifted its Parkes Project gold inventory to 383,300 ounces, led by a 228% increase at London-Victoria after an 85-hole drilling campaign. The company is now moving from resource definition towards metallurgical testing and a Scoping Study, although no production decision or project economics has been disclosed.

Anax Metals has moved its Whim Creek copper-zinc project closer to a targeted investment decision, backed by strong feasibility economics and new drilling. But the annual report makes clear that development still depends on securing further funding, with the auditor warning of a material uncertainty over going concern.

Antipa Minerals has selected a preferred processing and mine development configuration for its Minyari Dome project, combining gold doré with a separate copper concentrate. The decision advances the study, but pushes the pre-feasibility study release into November 2026 while costs and project economics are finalised.

EcoGraf has begun a European Investment Bank-funded study program worth up to €2 million to test expansion options for its Epanko graphite project and planned battery anode operations. The work could strengthen future financing and development decisions, but it remains a planning exercise rather than a construction commitment.

Parbo Resources has completed a $5 million IPO raise ahead of a proposed ASX listing, giving the pre-revenue explorer fresh funding for its Western Australian projects. Its FY2026 accounts show a $187,285 loss, $2.29 million in cash at year-end and $1.31 million in capitalised exploration assets.

VHM's refreshed feasibility study projects an A$807 million pre-tax NPV for its Goschen rare earths and mineral sands project, with approvals and major procurement work substantially advanced. The project still needs financing, lender due diligence and a Final Investment Decision before construction can begin.

Tambourah Metals has tightened drilling across its Tambourah King gold lode, returning several encouraging intersections ahead of a planned maiden resource estimate. Shallow results at Western Chief add a second exploration thread, although the system remains lightly tested at depth.

Argosy Minerals says laboratory-scale crystallisation testing has demonstrated a potential lithium chloride product yield above 99% at its 12,000-tonne-per-year Rincon project in Argentina. The results remove a key process uncertainty, but the project still depends on engineering completion, financing and a broader Definitive Feasibility Study.

Broken Hill Gold has lifted the Vertigo deposit’s Indicated oxide resource by 160% and increased White Dam’s global resource to 118,496 ounces. The company is now testing whether shallow material can support a heap-leach restart while drilling deeper gold-copper sulphide potential.
