Evolution Mining – Edna May


Western Australia



Project Highlights

GR Engineering was appointed by Catalpa Resources Limited to undertake the engineering, design, procurement, construction and commissioning of the Edna May gold processing plant. Catalpa had previously procured the old Big Bell processing plant, equipment and infrastructure to meet most of the processing requirements. Additional equipment was required to meet the new duty of the upgraded processing plant. Part of the GR Engineering scope was to manage the refurbishment of the Big Bell plant and incorporate the new equipment into the Edna May plant design.

The plant is designed to treat blended ore, at a throughput of 2.8 Mtpa. The grinding and wet plant circuits are designed to process ore at a treatment rate of 3.4 Mtpa. The plant has provision for a full expansion in processing capacity to 3.2 Mtpa.
