HALIFAX, Nova Scotia, April 20, 2026 (GLOBE NEWSWIRE) — Erdene Resource Development Corp. (TSX:ERD; MSE:ERDN; OTCQX: ERDCF) (“Erdene” or the “Company”) is pleased to provide a Bayan Khundii Gold Mine (“BK”) production update for Q1 2026, operated by Erdene Mongol LLC (“EM”), the Company’s joint venture with Mongolian Mining Corporation (“MMC”). All dollars are US unless otherwise noted.
Peter Akerley, Erdene’s President and CEO stated, “During the first quarter of 2026 the Bayan Khundii gold mine achieved commercial production, realizing average throughput of nearly 90% of nameplate capacity. Gold recovery during the quarter averaged over 96%, exceeding projections in the most recent feasibility study. As we transition through ramp-up, we are delivering higher grade ore to the BK process plant.”
Mr. Akerley continued, “With a 20% increase in sales compared to the first quarter of operations, Bayan Khundii has produced 15,961 ounces of gold to date.”
Mr. Akerley concluded, “With the proceeds from the financing completed during the quarter, Erdene is positioned to advance our wholly-owned high quality precious and base metal projects in the Khundii and Oyu Tolgoi districts. Exploration, technical studies and permitting are well underway.”
Bayan Khundii Gold Mine – Q1 2026 Update
Bayan Khundii processed 151 thousand tonnes of ore, averaging 1,675 tonnes per day, or 94% of the target production throughput during the quarter ended March 31, 2026.
The processed grade averaged 1.9 g/t gold for the quarter ended March 31, 2026, as lower grade ore was fed during the early part of the period, when mining was reduced to allow for the establishment of a single working level and access to multiple high grade zones. As operations moved into March, ore feed grades increased significantly, averaging 2.7 g/t gold for the month. Quarterly gold recoveries of over 96% were superior to the forecast average of 93%.
EM sold 8,527 ounces of gold and 3,135 ounces of silver at average prices of $4,872/oz and $80/oz, gold and silver, respectively, generating gross revenues of $42 million (C$57 million) during the quarter ended March 31, 2026.
EM’s focus in Q2 is on continued optimization of mining and processing operations. Grade control, blasting, mining, stockpile management, crushing improvements and processing throughput increases are aimed at reaching production consistent with historical projections. Those efforts are expected to deliver positive results as we move into Q2 aided by improved seasonal conditions for pit operations. In Q3, EM will update resources for the EM deposits and mineral reserves and mine plans for BK and Dark Horse.
