Dubbo Project resources and reserves

The Dubbo Project is based on the Toongi deposit.

The orebody is predominantly a massive fine-grained trachyte outcrop of Jurassic age. It has elevated levels of light and heavy rare earths, zirconium, niobium and hafnium.

The reportable Dubbo Project Mineral Resources and Reserves are based on the open pittable Toongi deposit, which has a depth extent of 115 metres below surface.

These Mineral Resources are wholly inclusive of Ore Reserves, which are based on economic parameters applied to the Mineral Resources, reflecting an initial project horizon of 20 years.
