The table contains rounding adjustments to reflect accuracy and may not total exactly. 2. This Ore Reserve was estimated from practical mining envelopes and the application of modifying factors for mining dilution and ore loss. 3. For the open pit Ore Reserve, dilution skins were applied to the undiluted Mineral Resource estimate. The method also included internal and edge dilution resulting from forming practical mineable shapes. Dilution was incorporated in the model at the background grades estimated into the model: The average grade of dilution for Waihi was 0.16 g/t. The estimated average dilution at Waihi was estimated to be 27%. Ore loss was incurred in the Auto Stope Designer (ASD) Deswik process due to variation between mineralised lode geometry and practical dig block geometry. In addition, a nominal 5% loss was applied for further mining losses occurring through normal operations. 4. For the underground Ore Reserve, dilution skins were applied to the Mineral Resource estimate. Dilution was included at the background grade estimated into each model. The Riverina dilution is estimated to average 59% while Sand King is estimated to average 29%, reflecting mining shapes and orebody widths appropriate for each deposit. 5. The Inferred Mineral Resource within the mining envelope was considered as waste when defining limits of these envelopes; however, minor amount of inferred material was included within the Riverina Underground and Sand King Underground mine plan due to practical mining geometries and orebody characteristics. 6. The Waihi open pit Ore Reserve was primarily estimated using a cut-off grade of 1.2 g/t based on a gold price of A$2,600/oz. Low Grade reserve was based on A$3,000/oz. Costs used in the cut-off grade calculation allow for ore transport, processing, site overheads and selling costs as well as a historical global process recovery of 92%. 7. The Ore Reserve is inclusive of surface stockpiles above cut-off. All surface stockpiles were classified as Proved. 8. All low grade material is in situ. 9. The Underground Ore Reserve was estimated using a cut-off grade of 2.5 g/t Au based on a gold price of A$2,250/oz, stopes were further spatially optimised. Costs used in the cut-off grade calculation allow for ore transport, processing, site overheads and selling costs as well as process recovery specific to the location. Process recoveries range for the project were estimated to be 87% or above, based on recent metallurgical test work. 10. Inferred material within total Underground Ore Reserve equates to 24,250t at a grade of 4.5g/t. This material is included at the edges of the mining envelope and equate to 2.5% of the Ore Reserve inventories. 11. Costs were derived from the FY25 budget estimate including underground contract pricing current at the date of this Ore Reserve and budget level contract pricing for Waihi. Unit costs for haulage, processing and site overheads were estimated based on scheduled process plant throughput of material above the economic cut-off grade. Full utilisation of process capacity is reliant on realising expected conversion of further Mineral Resource to Ore Reserve. For personal use only
