Copper 360 Limited Advances Underground Development At Rietberg Mine Beyond Halfway Mark Towards 300 Level Orebody Copper 360 Limited has achieved a significant development milestone at its flagship Rietberg Mine, with underground development now advancing beyond the halfway mark towards the 300 Level orebody. Underground development at the Rietberg Mine has advanced beyond the halfway mark of the original 544-metre development to 300 Level. The development is expected to intersect ore on 300 Level within 90-days, providing access to the defined ore block expected to supply mill feed for approximately three years of mining at Rietberg. The build-up to full production will commence during the on-ore development phase, with run-of-mine production expected to reach approximately 700 tonnes per day once ramped up– sufficient to fill the capacity of the Company’s MFP2 processing plant. Concurrently, a haulage decline will be developed down to 350 Level, which will further increase the available mining face length and support the longer-term production profile. Underground development toward 300 Level has now advanced beyond the halfway mark of the original 544-metre development. Development rates have continued in line with the mine plan, supported by the Company’s mining alliance with Cementation Africa, which commenced mobilisation on 1 July 2026. Based on current advance rates, the development is expected to intersect ore on 300 Level within 90-days. This intersection will provide access to the defined block of ore which is expected to supply mill feed for mining operations at Rietberg and marks the transition of the operation from waste development into on-ore development and in-situ production build-up. The build-up to full production will commence during the on-ore development phase, with ore generated from development immediately contributing to plant feed. Run-of-mine production is expected to build up to approximately 700 tonnes per day in the near term, which is sufficient to fill the processing capacity of the Company’s MFP2 modular flotation plant following its recent conversion to parallel milling. The alignment of the mine’s production build-up with the upgraded capacity of MFP2 is a key milestone in the Company’s strategy: for the first time, a consistent, structured hard-rock ore supply from Rietberg will fully utilise the Company’s installed processing capacity, supporting improved feed grades, recoveries and copper production. Concurrently with the production build-up on 300 Level, the Company will develop a haulage decline down to 350 Level. This decline will open up additional mining headings and further increase the available face length, providing the operational flexibility to sustain and grow production beyond the initial build-up and underpinning the longer-term production profile of the mine. The Company will update the market on the intersection of ore on 300 Level, the progress of the production build-up, and the advancement of the haulage decline to 350 Level in due course.
