Orvana Minerals Corp. provides updates on the Oxides Stockpile Project at its Don Mario operation in Bolivia. EMIPA has commenced operational trials by processing legacy sulfide ore through the Au-Ag circuit as part of the Don Mario plant restart.
Initial doré production is expected to commence in the second half of February 2026, subject to successful completion of performance verification activities. The next operational milestones include the completion of construction of the Cu circuits and the phased integration of all processing circuits, with commissioning expected to be fully completed early in the third quarter of fiscal 2026. Processing of the oxide stockpiles is expected to begin thereafter and to ramp up progressively through the third quarter of fiscal 2026, with the objective of achieving full operational capacity during the fourth quarter of fiscal 2026.
The timing and pace of ramp-up will depend on plant performance, equipment reliability, and the optimization of operating parameters. As previously disclosed, EMIPA completed an on-site pilot test on representative oxide material. Based on the results of this pilot test, together with pre-existing metallurgical data, the Company has set forth its planning for the processing of its oxide stockpiles.
For fiscal 2026, the plan assumes Au?Ag?Cu recoveries at levels below long-term expectations, reflecting the early stages of ramp-up and the ongoing optimization of process efficiency. Production and recovery rates are expected to improve over time as operational practices are fine-tuned, and equipment performance stabilizes.
