December 2025 Group Mineral Resource Statement
Telfer grows to 8.0Moz (+150%), supporting a long-life operation
Telfer adds 4.8Moz of gold Mineral Resources at a discovery cost of $5 per ounce
Telfer Measured and Indicated Resource growth of 163% to 3.8Moz
Telfer and Havieron Mineral Resources of 14.9Moz ounces gold and 645kt of copper
Outlook:
- H1 FY26 infill drilling successfully delivered a major upgrade in the M&I category supporting
an updated Telfer Ore Reserve Estimate targeted for the June 2026 Quarter.
- Following significant resource growth, particularly in the M&I category, Greatland’s focus
now shifts to advancing higher-grade opportunities including WDU and the MDU sub-
level cave area.
- Record FY26 drilling program continues with >100,000 metres of further drilling planned for
H2 FY26 and a substantial drilling program expected for FY27
Economic factors: Telfer MRE incorporates updated cost (based on CY25 actuals) and revenue
assumptions with assumed metal prices of A$4,200/oz for gold and A$6.50/lb for copper, compared
to spot prices of ~A$6,500/oz and ~A$8.00/lb respectively
Greatland Managing Director, Shaun Day, commented:
“Telfer and Havieron’s combined resource of 550Mt @ 0.84g/t Au & 0.12% Cu for 14.9Moz Au & 645Kt Cu
has the potential to underpin a multi-decade, world class mining hub. Our investment in significantly
increased drilling has delivered substantial organic growth, with the overall Telfer resource growing by
150% to 8.0Moz, and the higher confidence Measured and Indicated component by 163% to 3.8Moz.
“The growth includes a high-grade maiden resource at the West Dome Underground project, which shows
significant potential for a new mining front at Telfer and remains the focus of ongoing drilling.
“This strong resource update has been delivered by Greatland’s dedicated technical team who have
executed an accelerated and extensive Telfer drilling program since taking ownership in December 2024.
“The significant growth in Measured and Indicated Resources, particularly at the West Dome Open Pit, is
very pleasing with this material being of adequate geological confidence to be evaluated as part of our
upcoming Ore Reserve estimate, which remains targeted for the June 2026 quarter.
“The scale of Telfer’s resource demonstrates clear potential to fully utilise our low cost 20 million tonne per
annum processing infrastructure well into the future. The technical team’s focus is now to advance our
higher grade opportunities including the West Dome Underground and the potential to restart Main Dome
Underground’s sub-level cave, which could augment our development of Havieron.”
