Hera

Hera site is located approximately 100km southeast of Cobar in central-west NSW.

In March 2023, the last ore from the underground mine was hauled to the surface and processed through the plant, and Hera’s surface facilities were transitioned to care and maintenance in April 2023.

The 455ktpa process plant is equipped with a three-stage crushing, gravity gold, base metal flotation and concentrate leach circuits. We intend to leverage the established infrastructure at our Hera site to process ore from our nearby Federation Project.

Since commissioning in 2014, Hera has produced 3.2 million tonnes of ore, supported 180 full time jobs, and contributed A$216 million to the local economy.
