The Windimurra Igneous Complex is part of the c. 2813 Ma Meeline Suite of mafic-ultramafic layered intrusions of the central Murchison Domain, Yilgarn Craton of Western Australia.
Exploration has focused on finding basal nickel sulfide and chromitite deposits, although that has proved fruitless as the lower zone is not exposed.
The Shepherd's Discordant Zone is host to a laterally extensive vanadiferous magnetite and ilmenite adcumulate and mesocumulate deposit, forming a resource in excess of 120 Mt grading 5% V2O5.
PMA being the original developer retained 49% ownership and was appointed as the projects manager to oversee the detailed design, construction and commissioning of the Vanadium Processing plant.
This can be explained through poorly conceived wholesale changes made to the processing plant, along with a misconception to focus the mine on the deeper fresh Magnetite zones which result in high strip ratios.
The economic key to Windimurra, is the ability to produce a low cost, reasonable quality Magnetite Concentrate to feed the site large Rotary Kiln.
