Erdene Announces Year-End Results and Provides Bayan Khundii Project Update

HALIFAX, Nova Scotia, April 02, 2024 (GLOBE NEWSWIRE) -- Erdene Resource Development Corp. (TSX:ERD; MSE:ERDN) ("Erdene" or the "Company") is pleased to announce operating and financial results for the year ended December 31, 2023, and to provide an update on progress at its Bayan Khundii Gold Project ("BK" or "Project"). This release should be read in conjunction with the Company's 2023 Financial Statements and MD&A, available on the Company's website and SEDAR+.

Peter Akerley, Erdene's President and CEO stated, "The past year was a transformative period for Erdene with the striking of our Strategic Alliance with Mongolian Mining Corporation ("MMC"), Mongolia's leading publicly traded mining company, the commencement of construction at the Bayan Khundii gold project and continued exploration success across the Khundii Minerals District."

He continued, "The Bayan Khundii gold mine is one of the highest grade, open pit gold mines under development globally and will be Mongolia's largest primary gold producer when it reaches full production. With early works complete, project finance secured, long-lead orders now arriving to site and the 2024 construction season underway, we are on track to produce first gold at Bayan Khundii in Q2 2025."

Mr. Akerley concluded, "Exploration during the 2023 field season further expanded mineralization in our Khundii Minerals District, located in an under-explored, world-class gold and copper belt. We have established a pipeline of high-quality projects, including high-grade gold satellite deposits to Bayan Khundii, the large Altan Nar gold-polymetallic deposit and the vast Zuun Mod molybdenum-copper porphyry resource. We plan to work with our strategic partner MMC to build upon our exploration success to unlock new opportunities for the Mongolian mining sector, increase the industry's contribution to the national economy and create long-term value for Erdene shareholders."
