Erdene Resource Development Corporation has provided an operational update for its Bayan Khundii Gold Mine, operated through its joint venture Erdene Mongol LLC with Mongolian Mining Corporation. In the fourth quarter of 2025, the mine sold 7,434 ounces of gold and 2,634 ounces of silver at average prices of US$4,153 per ounce of gold and US$53 per ounce of silver, generating US$31 million in gross project revenues. The processing facility averaged 77% of its 1,950 tonne per day design capacity during the quarter and reached nameplate mill throughput for much of December. A total of 144,845 tonnes of ore were processed, with an average gold grade of 2.0 grams per tonne. Additionally, Erdene completed 5,433 metres of drilling at the nearby Dark Horse and Altan Arrow gold prospects, with results expected in the first quarter of 2026. Ongoing metallurgical studies are assessing the suitability of this ore for heap leach processing, which could support future mine expansion and provide additional resources for the Bayan Khundii CIP plant.
