Mount Gibson Gold Project

Project
Proponent: 
Crimson Metals Pty Ltd
Proposal description: 

Crimson Metals Pty Ltd is proposing to develop the Mount Gibson Gold Project, located approximately 280 km northeast of Perth and less than 10 km east from the Great Northern Highway, in the Avon Wheatbelt region of Western Australia. Substantial mining occurred in the 1980’s and 1990’s and as a result, historical disturbance and infrastructure remain in the area.

The proposal encompasses the re-opening and enlargement of existing open cut mines, utilisation of existing infrastructure where practicable, development of a new gold processing plant and associated infrastructure.

The proposal is estimated to process five million tonnes per annum of ore over an 11 year mine life. The Development Envelope is up to 4,082 ha with a Disturbance Footprint of 1,686 ha of which approximately 1,296 ha is comprised of native vegetation and approximately 390 ha previously disturbed.
