Pilbara Iron Project (Rocklea Deposits)

The Pilbara Iron Project is Riva’s most advanced project, comprising the Rocklea channel iron deposits (CID) within the world class Pilbara Iron Ore Province of Western Australia.

The Rocklea deposit is located 33km southwest of the mining town of Tom Price on the eastern margin of the Rocklea Dome where the Archaean Fortescue Group is overlain by Tertiary CIDs and other Cainozoic deposits of sand and gravels. The CIDs comprise goethitic and hematitic detrital deposits of the Tertiary Robe Pisolite.

The project is ideally placed to be one of the Pilbara’s next producing iron ore mines with an Indicated and Inferred Mineral Resource of 383.1Mt at 50.94% Fe using a 45% Fe cut-off grade, which includes a higher grade component of 263.6Mt @ 52.6% Fe using a 50% Fe cut-off grade.

A number of studies and negotiations have been completed on the project. A scoping study was prepared by GHD in January 2012, which analysed the technical and economic viability of the project. Feasibility studies for the project commenced in 2013 with a Mining Proposal for the planned “Rocklea Early Tonnes” mining development submitted to the Department of Mines and Petroleum (DMP). Studies continue to investigate transportation options for the Project.
