Construction Progress

Era Dorada continued to gain momentum during the quarter, reaching 13.1% overall physical progress, with construction at 7.6% and engineering at 46.6%. The earthmovings activities for the Operational Plateau is concluded. Civil works across key process plant areas, including crushing, grinding and CIL is ongoing, while the CITIC mills progressed and the project moved toward the start of electromechanical erection. Importantly, key project milestones remain unchanged.

In the underground mine, activity ramped up during the quarter. The mining contractor was mobilized, short-term delineation drilling commenced to support the 2028 mine plan, and the pilot drilling started at one of the ventilation raise. Mine infrastructure also advanced, including the temporary refrigeration plant, underground equipment deployment, waste-dump drainage and synchronization of the power generators.

This broader ramp-up has been achieved while maintaining a strong safety performance, with 622 days and more than 711,000 work hours without a lost-time injury. Overall, construction, underground mine development and supporting infrastructure are now advancing simultaneously across multiple fronts, on time and on budget.
