The proposal is to develop an open-cut lead carbonate mine and processing facilities approximately 30 kilometres west of the Wiluna townsite to produce a lead concentrate. The lead concentrates will be refined at the Wiluna minesite to produce lead metal, or alternatively will be transported by road to the Geraldton Port and exported.

Post-assessment changes to the proposal stipulate that the lead carbonate concentrate produced at the mine-site is transported in sealed bags within locked shipping containers by road from the mine-site to Leonora and then by rail to the Port of Fremantle where it is exported.
