Greatland Resources Limited has announced its March 2026 Group Ore Reserve Estimate, which shows a significant 62% increase to 5.0 million ounces of gold (Moz) and 196,000 tonnes of copper (kt Cu). The increase is primarily due to a 150% rise in the Telfer Ore Reserve to 1.8Moz, with the Havieron Ore Reserve remaining unchanged. The Telfer West Dome Open Pit Ore Reserve increased by 375% to 1.4Moz, while the Main Dome Underground Ore Reserve was confirmed at 0.2Moz. The company is continuing high-cadence drilling and studies to target further reserve growth, with substantial Inferred Resources identified that could be converted to Ore Reserves in the future. The March 2026 Group Ore Reserve is based on the December 2025 Mineral Resource Estimate and includes updates from ongoing drilling as at 31 March 2026.

Group Ore Reserve grows to 5.0Moz; Telfer Ore Reserve increases to 1.8Moz
