Jubilee Metals provides Roan copper concentrator update

Jubilee, the integrated copper producer and resource developer in Zambia, is has provided an operational update on its Roan concentrator (Roan) operations, following the successful completion of the scheduled annual maintenance shutdown and the resumption of commissioning and ramp-up activities of the fine copper concentrate dewatering circuit.

HIGHLIGHTS

• Roan annual maintenance shutdown completed during May 2026, with operations
• successfully resumed at full capacity targeting run-of-mine throughput of 30 000tpm
• New fine copper concentrate dewatering facility commissioning completed with fine
• tuning of performance measures underway to achieve stable continuous operations
• Maintenance period utilised to upgrade the copper oxide flotation circuit to target further improved copper recoveries and enhance operating efficiencies, partly offsetting rising fuel and chemical costs

“The successful progression of the Roan dewatering circuit through commissioning and ramp-up marks another important milestone in the expansion of our Zambia copper operations, says Leon Coetzer, Jubilee CEO. “The ability to process both newly generated fine concentrate material together with the historical stockpile provides increased operational flexibility and supports the continued scaling of our integrated copper strategy. While May 2026 production was impacted by the planned annual maintenance shutdown at Roan, operational performance has returned to full capacity targeting a processing run rate of 30 000tpm of ROM with increased copper oxide recovery rates due to the expanded flotation circuit. We expect June 2026 performance to provide a clearer indication of sustainable operating capacity and recovery efficiencies with the addition of the fines concentrate from Roan now being processed at Sable. As previously noted, the monthly fines concentrate production contains an approximate 140t of copper previously stockpiled at Roan.”
