Project Overview

Mt Morgan is located in Queensland and was the largest gold mine in the world at its peak in the early 1900s. Over its lifespan, the mine yielded approximately 262 metric tons of gold, 37 metric tons of silver and 387,000 metric tons of copper.

Operations at Mount Morgan closed in 1990 and the abandoned mine has since been managed by the Queensland Government, which is also providing financial support to the project through the Invested in Queensland program.

The recovery of gold and copper from tailings will help meet increasing demand for the resources required for the clean energy transition, while also improving environmental outcomes for the region and industry.

Public Impact

An independent economic analysis has shown the project will provide significant benefits worth $849 million to northern Australia.
