IGO Limited has released its Mineral Resources and Ore Reserves report for the period ending 30 June 2026, re-reporting estimates for the Greenbushes operation while advancing portfolio changes at the Nova asset.

Rather than applying full end-of-year survey depletion, IGO has re-reported Greenbushes estimates using an effective date of 31 December 2025. Because those figures have not been revised or mine survey depleted to 30 June 2026 by Greenbushes' JORC Code Competent Persons, the company has applied second-half FY26 ore processed as a proxy for mining depletion to satisfy ASX listing rules.

That baseline follows the earlier December 2025 resource update for Greenbushes, which recorded a total Mineral Resource Estimate mass of 457 million tonnes of ore grading 1.6% lithium oxide.

Operations at Greenbushes experienced a temporary interruption following a June 2026 fire at Chemical Grade Plant 3, with production at the facility expected to recommence in the days following the July 2026 quarterly report. IGO holds a 24.99% indirect interest in the operation.

At the 100% owned Nova Operation, activities are focused on the final phase of operations ahead of a planned exit. Divestment activities and final production for Nova are targeted to occur within the December quarter of 2026.
