Latest Ore Reserve Estimates News

Pilbara Gold has lifted the Mt York resource by 50% to 2.08 million ounces while advancing a prefeasibility study and restarting drilling at Roe Hills. The annual report also warns that planned exploration spending could require another capital raise within 12 months.

Lake Resources has secured the primary provincial environmental permit for its Kachi lithium project in Argentina, clearing the way for detailed engineering and financing work. The approval removes a major development hurdle, but FEED, funding, RIGI approval and a final investment decision remain ahead.

IperionX has moved its Virginia titanium operation into 24/7 production, lifting nameplate powder capacity to about 200 tonnes a year while commissioning equipment aimed at higher-value components. The progress came alongside a US$66.8 million annual loss, US$63.5 million of operating and investing cash outflows, and continued reliance on government support, customer qualification and future capital.

Zimplats delivered a sharp FY2026 earnings rebound, with revenue up 57% and profit after tax rising to US$276.7 million. The result was driven mainly by stronger PGM prices, while lower sales volumes, higher unit costs, no dividend and rising sulphur dioxide emissions temper the celebration.

Mont Royal Resources has used its first post-merger annual report to set out the scale of the Ashram rare earths project, while flagging the funding, permitting and technical work still ahead. The updated study outlines a 30-year operation with a C$2.03 billion post-tax NPV, but remains a preliminary assessment rather than a development guarantee.

Cavalier Resources has lifted the Crawford Gold Project’s Stage 1 NPV by about 50% to A$77.2 million, while drilling supports extensions beyond the planned starter pit. But the annual report also flags a material uncertainty over going concern, with proposed project financing still subject to definitive documentation.

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.

Toubani Resources has reported high-grade RC drilling at Foroko, a satellite deposit 3km from the Kobada processing plant in Mali. The results are sufficient for Foroko to be considered in an October Mineral Resource Estimate update, but no additional ounces have yet been declared.

Terrain Minerals has recorded gold recoveries of up to 93.7% from first-pass metallurgical testing at its Lightning Gold Project, using a conventional gravity and carbon-in-leach flowsheet. The results reduce a key technical uncertainty, although the work remains preliminary and is based on only three RC chip composites.

McLaren Minerals has reported broad, near-surface heavy mineralisation from 61 holes at its Western Australian titanium project, led by 24 metres at 7.54% HM. The results strengthen the dataset for a resource update, but do not yet establish an Ore Reserve or project economics.

Western Gold Resources is pursuing multiple processing alternatives for Gold Duke after Wiluna Mining deferred third-party tolling, while revising the project’s study around a larger resource. The company is also considering corporate opportunities, but no processing agreement, transaction or expanded mine plan has been secured.

Kingsgate Consolidated has increased Nueva Esperanza’s Ore Reserves by 31% for silver and 37% for gold, extending the assumed reserve life beyond 12 years. The gains are largely driven by higher price assumptions and lower royalties rather than new drilling.
