DUKETON OPTIMISATION

Conversion of low-grade resources into reserves

Detailed studies during FY21 has converted significant resources into reserves
Operating life extended to 2028 with Ore Reserves increased by 20% net of mining depletion – 700koz added including 300koz of LG stockpiles
Significant low-grade, oxide resources being exploited to extend the life of the operation
Options are also being considered to debottleneck and expand the milling capacity to grow production and reduce costs

20 ACCELERATING DISCOVERY FOR LONG TERM LIFE

Exploration budget increased to A$28m for FY21
Greenfields exploration portion now A$23.5m versus A$5-7m per year historically
Accelerated exploration on Ben Hur OP and high-grade UG extensions
Expanded Greenfields exploration activities on newly acquired tenure will generate new large gold targets (+1Moz)
