Full summary
Aurelia Metals Limited (ASX: AMI) has reported its annual Mineral Resource and Ore Reserve Statement, highlighting a strong growth in Group Mineral Resource and Ore Reserve Estimates. The Group Mineral Resource estimate increased after depletion to 30.6Mt (29Mt in 2025), comprising 28.0Mt in underground Resources and 2.6Mt of Resources for New Occidental Tailings. The Group Ore Reserve estimate increased 49% after depletion from 2025 to 8.2Mt, comprising 5.9Mt of underground Reserves and 2.3Mt of Reserves for New Occidental Tailings. Peak evolving as the Group's copper-gold cornerstone, with the underground Mineral Resource estimate increased after depletion to 21.4Mt, including 19.6Mt of copper Resources at 1.8% Cu and 0.8g/t Au. The underground Ore Reserve estimate increased 22% after depletion to approximately 4.1Mt, including a strong gold grade of 1.8g/t Au in addition to the primary base metal content. The underground Production Target increased after depletion by 25% from 2025 to approximately 6.4Mt, with significant expansion potential, especially at Great Cobar once exploration platforms are established to drill from underground. Federation grades increase significantly, with the Mineral Resource estimate defining a higher-grade base metal deposit through infill drilling, with 14.7% Pb+Zn (2025: 12.1% Pb+Zn), over more constrained tonnes, with similar gold grades, and a significantly higher proportion in the Measured category (16%, up from 2% in 2025). Exploration decline designed and planned to be excavated during FY27 to provide valuable platforms for extensional drilling. New Occidental Tailings to add incremental production value, with a Mineral Resource estimate of 2.6Mt at 0.65g/t Au, and an Ore Reserve estimate of 2.3Mt at 0.64g/t Au, intended to be processed through the Peak processing plant in parallel to the 1.1-1.2Mt of fresh ore feed. Feasibility Study in progress through H1 FY27.
