Telfer growth and exploration

• Telfer has two 10Mtpa processing trains, 20Mtpa combined nominal capacity, and is described as Australia's third-largest gold or gold-copper processing facility.

• FY27 Telfer growth capital targets mine development, open-pit fleet renewal, infrastructure and power upgrades, West Dome Underground (WDU) early works, studies and tailings capacity.

• Planned FY27 drilling is 215km, targeting West Dome open-pit extensions, Main Dome underground and WDU; the WDU maiden resource is 8Mt at 2.3g/t gold and 0.44% copper.

• FY27 milestones include Telfer resource and reserve updates, WDU and Vertical Stockwork Corridor studies, and review of O'Callaghans options including spin-out, divestment or partnership.

• O'Callaghans has a 70Mt resource at 0.35% WO3, containing 246kt WO3; the deposit also contains copper, zinc and lead and lies ~10km south of Telfer.

Havieron development and economics

• Havieron Ore Reserve is 38.5Mt at 2.63g/t gold and 0.33% copper, containing 3.3Moz gold and 128kt copper; it is described as Australia's third-largest underground gold reserve.

• Pre-production capex is A$1,065m; the plan uses a 3-year ramp-up, then conveyor haulage supporting up to 4.5Mtpa production.

• Standalone case at A$4,500/oz long-term gold: post-tax, unlevered FCF $5.4bn, NPV5 $2.9bn, IRR 22.5% and payback 4.2 years; at A$6,250/oz, NPV5 is $5.4bn, IRR 31.5% and payback 3.2 years.

• Standalone steady-state AISC is A$1,610/oz; co-processing with Telfer feed could lower Havieron costs through shared processing, site services and sustaining capital.
