First ore at Robe Valley (Mesa B, C, H) was achieved in August 2021. Ongoing Mesa A wet plant construction and commissioning challenges have impacted production ramp-up. New wet plant components are on order and production will operate at a reduced capacity until repairs are completed.
The autonomous mining truck fleet has been commissioned: since achieving first ore in August 2021. |

Summary:
• The Mesa B, C, and H deposits are Channel Iron Deposits (CID).
• The deposits are a part of a series of flat topped hills, defining the paleochannel of the Robe River. They consist of pisolite infilling the paleochannel, which cuts across the Cretaceous to Proterozoic stratigraphy.
• Mineralisation is confined to the Tertiary Pisolite.
• A hydrated hardcap overlies the mineralised pisolite.
• Non-mineralised clay layers and pods have been domained separately.
Summary:
All mines operated by Rio Tinto within the Robe Valley property are open pit mines. The mining method employed uses conventional surface mining, whereby shovels and loaders are used to load drilled and blasted material into trucks for removal to waste dumps or feed to process plants.
