Empresa Minera Paititi S.A. (“EMIPA”) owns and operates Don Mario under a number of concessions in the Don Mario district located in south-eastern Bolivia. In the first quarter of fiscal 2020 EMIPA made a decision to temporarily suspend mining and milling operations. EMIPA is now transitioning to the Oxides Stockpile Project, which involves a plant expansion to treat ore stockpiled from previous years of mining activity. In December 2025, EMIPA commenced verification of the Au-Ag circuit. EMIPA expects to commence metal production in the second quarter of fiscal 2026, while completing the commissioning of the Cu circuits and the integration of all plant circuits. 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.
