ERDENE PROVIDES Q1 2026 BAYAN KHUNDII GOLD MINE UPDATE
Press Release
Halifax, Nova Scotia
2026.04.20
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.
