Mineral Resources and Ore Reserves

Mining at Tomingley has been based on the Wyoming (One and Three) and Caloma (One and Two) gold deposits since 2014, with underground mining commencing in 2019.

The Tomingley Gold Extension Project is founded on the San Antonio and Roswell (SAR) gold deposits, located immediately to the south of the existing operation. Like the Caloma and Wyoming deposits, the SAR deposits are interpreted as orogenic gold systems positioned within a major structural zone. Their similar geology to the Caloma and Wyoming deposits make them ideal feedstock for the existing processing plant.

In 2021, the SAR resources and reserves were incorporated into the Tomingley Life of Mine Plan, incorporating open cut and underground operations.

The following tables detail the Mineral Resources and Ore Reserves for Tomingley Gold Operations.
