Mount rawdon

The Mount Rawdon open pit gold mine in the Maryborough Region of Queensland, 75 kilometres from Bundaberg, commenced production in 2001. It is fully owned by Evolution Mining, a company formed as a result of a merger between Catalpa Resources Limited and Conquest Mining Limited.

Mount Rawdon Open pit Mining Uses Conventional Methods
The Mount Rawdon Mine consists of one open pit that uses the usual mining method of drilling, blasting, loading and hauling. All these various mining activities are carried out by individual contracting firms managed overall by Evolution Mining staff. The life of mine is estimated to expire in 2023 at current production levels.

Mount Rawdon has its own Gold Processing Facility on Site
The Mount Rawdon gold mine has its own gold processing facility that consists of primary and secondary crushing of the ore, a SAG and ball mill followed by a cyanide leaching process. The mill capacity is averaging around 3.5 million tonnes of gold bearing ore a year with a recover rate of around 90 percent.

Planned efficiency improvements to be undertaken at Mount Rawdon include:
- An ore blending strategy to enable mill reline shut-down schedules to be able to be forecast well in advance
- The mid 2013 installation of a leach reactor into the gravity circuit to deliver improved gold recovery results
- Reduced cyanide consumption
- Improved silver recovery as a result of lower gold loading on carbon
