The Jimblebar Optimisation Project is a revision of the existing Jimblebar Iron Ore Mine approved under Ministerial Statements 683, 809 and 857.

The Revised Proposal is for mining operations at Jimblebar, located approximately 40 km east of the town of Newman.

Mining of iron ore deposits will be undertaken above and below the water table. Mining operations will include open pits, overburden storage areas and the construction and operation of associated mine, processing and rail infrastructure.

The Revised Proposal would require additional clearing of up to 2000 hectares of native vegetation and changes to the management of surplus water.

Groundwater will be abstracted for water supply and to dewater the orebodies. Surplus water management will include transfer to Ophthalmia Dam, controlled creek discharge and managed aquifer recharge
