In August 2026, mining companies in Western Australia reported significant developments regarding gold resources and reserves.

Forrestania Resources announced a 131% increase to the mineral resource estimate at its British Hill deposit, bringing the total to 2.62 million tonnes grading 1.50 g/t gold. This update followed extensive drilling programs and supports the company’s hub-and-spoke strategy involving the Lake Johnston processing plant.

Later in the month, Maritana Minerals declared a maiden underground ore reserve for its Rose Hill Project near Coolgardie. The reserve is estimated at 420,000 tonnes at 2.34 grams per tonne of gold. The company intends to transport ore to the Black Swan Processing Hub, with a goal to begin gold production in the second half of 2027.
