The study highlights the current operational success while building on the infrastructure, underground access and operating platform already established at site and provides a robust centralized foundation for the building of our district scale vision. Our focus now is to advance from this study and continue de-risking the Project toward the next stage of technical evaluation and permitting.”

The PEA evaluates a conceptual development scenario for the Bralorne Gold Project based on the current Mineral Resource Estimate with an effective date of June 1, 2026. The assessment considers underground mining utilizing long-hole stoping mining methods and a nominal processing capacity of 2,700 tonnes per day (“ tpd ”) through a combination of sorting and milling. Once in commercial production the Project would produce on average 110 thousand ounces of gold ( “oz”, “AU” ) per year with doré smelted on site. Table 1 below presents the key results from the study.
