Rio Tinto has disclosed the maiden Inferred Mineral Resource at the 100% owned Winu copper-gold project and revealed the discovery of a new zone of gold dominant mineralisation approximately 2 km east of the Winu deposit in the Paterson Province of Western Australia. The Inferred Mineral Resource, reported at a 0.2% copper equivalent cutoff, is 503Mt at 0.45% copper equivalent. This includes a higher grade component of 188Mt at 0.68% CuEq at a cutoff grade of 0.45% CuEq. Study work to date suggests the copper mineralisation supports the development of a relatively shallow open-pit mine, combined with industry-standard processing technology that is used at other Rio Tinto sites. Drilling continues to refine the overall geometry of the system and controls. The deposit remains open at depth as well as to the north and southeast Figures 1 to 4. The Winu project team continues to work with local Nyangumarta and Martu Traditional Owners and regulators to progress the agreements and approvals required for any future development. We are targeting first production from Winu in 2023, subject to securing all necessary approvals.

The discovery of a new zone of gold dominant mineralisation approximately 2 km east of the Winu deposit, at a prospect called Ngapakarra, as well as a number of other encouraging drilling results in close proximity to the maiden Winu Resource, provides further encouragement about the potential for the development of multiple ore bodies within one system.

Rio Tinto group executive of Growth & Innovation and Health, Safety & Environment Stephen McIntosh, said “We’re taking a more agile and innovative approach at Winu, and are working on the studies for a small-scale, start-up operation focused on Winu’s higher-grade core as we take another step towards commercialising this deposit. We are also assessing options for future expansion in the Paterson region given the extent of mineralisation identified to date and our large land package.”
