Operational Foundations
- High-grade underground ore mined during CY26 has been stockpiled at Laverton, providing early mill feed on commissioning of Brightstar’s processing plant in June CY27
- Brightstar maintains in-house underground mining expertise, operating an owner-operator model with its own fleet and workforce – de-risking ramp up and operations at Fish and Yunndaga
- Established Laverton operating base, workforce and haulage network underpin the staged development of the Goldfields Hub deposits
