With a strong partner in MMC and several growth projects, we are excited to expand opportunities within the district and contribute to the communities in which we operate.”Mr. Akerley continued, “We are very pleased with progress during the initial months of operations at the Bayan Khundii Gold Mine. Additionally, recent exploration expanded gold mineralization at Dark Horse, complementing the high-grade reserve scheduled to be mined and processed at Bayan Khundii starting in Q3 2027. We see multiple opportunities on license to extend the mine life or expand operations at Bayan Khundii.”Mr. Akerley concluded, “We also advanced our wholly owned projects in 2025. In October, we announced an updated independent mineral resource estimate for our Zuun Mod Molybdenum-Copper project, confirming the project as one of Asia’s largest undeveloped projects. Additionally, we executed an option agreement to acquire an up to 80% interest in a property adjacent to Oyu Tolgoi, one of the largest copper-gold deposits globally. Funds from the financing in early 2026 position us to accelerate development of these projects.”2025 Highlights and Significant Subsequent Events:Images – clockwise from top left: Bayan Khundii Mine Area, EM Mining team, Process Plant, EM Processing teamBayan Khundii Gold Mine – 50% Economic InterestKhundii Minerals District Exploration & DevelopmentCorporateResults Conference CallManagement will host a webcast and conference call to discuss these results and current business initiatives on Wednesday, March 25, 2026, at 9:00 AM Eastern Time.
