The gold equivalent (AuEq) is based on assumed prices of US$1,700/oz Au and US$3.75/lb Cu or Mineral Resource and metallurgical recoveries based on block metal grade, reporting approximately at 87% for Au and 87% for Cu which equates to a formula of approximately AuEq = Au (g/t) + 1.6 * Cu (%); In Greatland's opinion both gold and copper have a reasonable potential to be recovered and sold.

Mineral Resource & Ore Reserve statement Greatland reports its Mineral Resource and Ore Reserve estimates inline with the 2012 JORC Code. (1) Telfer Mineral Resources are reported as at 31 December 2024, grades are reported to two decimal places to reflect appropriate precision in the estimate, and this may cause apparent discrepancies in totals. Cutoffs for the Telfer MRE are applied based on a NSR using metal prices of A$3,450/oz Au and A$5.30/lb Cu for the West Dome cutback & stockpiles and A$3,150/oz and A$5.30/lb for the Main Dome underground. The Company confirms that it is not aware of any new information or data that materially affects the Telfer Mineral Resource estimate. (2) Mineral Resources are reported as at 31 December 2024, grades are reported to two decimal places to reflect appropriate precision in the estimate, and this may cause apparent discrepancies in totals. Cutoffs are applied based on a NSR using metal prices of A$3,450/oz Au and A$5.30/lb Cu for the West Dome cutback & stockpiles and A$3,150/oz and A$5.30/lb for the Main Dome underground. (3) Havieron Mineral Resource as per Greatland’s RNS announcement of 21 December 2023 titled ‘Havieron Mineral Resource Estimate Update’ are inclusive of Ore Reserve. Results are reported to one (gold) and two (copper) significant figures to reflect appropriate precision in the estimate, and this may cause some apparent discrepancies in totals. Mineral Resources in the South East Crescent and Link Zone are reported within a A$80 NSR/t shell while Mineral Resources in the Breccias are reported within a A$50 NSR/t shell. The Company confirms that it is not aware of any new information or data that materially affects the Havieron Mineral Resource estimate. (4) 2024 Group Ore Reserves are reported as at 31 December 2024. Grades are reported to two decimal places to reflect appropriate precision in the estimate, and this may cause apparent discrepancies in totals. Telfer: The 2024 Telfer Ore Reserve estimate is based on the December 2024 Telfer Mineral Resource detailed in the Company’s announcement of 18 March 2025 titled '2024 Group Mineral Resource Statement’. Cut-offs for the Telfer Ore Reserve are applied based on net smelter return (NSR) for each mining location, averaging A$24.8/t processed for open pits and A$13.7/t to 17.2/t processed for stockpiles, and metal prices of A$3,450/oz and A$4.16/lb copper and exchange rate of 0.65 USD per AUD. Material assumptions on which the Telfer Ore Reserve is based are detailed in the Material Information Summary included in this announcement and in the technical information included in the appendices. While the Company considers all the material assumptions to be based on reasonable grounds, there is no certainty that they will prove to be correct. No comparison is made to historical Ore Reserves. Cut-offs for the Havieron Ore Reserve are applied based on an NSR of A$95/t processed, and metal prices of US$1,450/oz and US$3.23/lb copper and exchange rate of 0.73 USD per AUD.Reserves are reported within mining shapes based on a sub-level open stoping mining method.
