ERDENE DELIVERS BAYAN KHUNDII GOLD

PROJECT FEASIBILITY STUDY

Press Release

Halifax, Nova Scotia

2019.09.02

Erdene Resource Development Corp. (TSX:ERD; MSE:ERDN) ("Erdene" or the "Company") is pleased to

announce the filing on SEDAR of the independent Feasibility Study (“Feasibility Study” or “FS”) Technical

Report (the “Report”) for its 100%-owned, high-grade, open-pit Bayan Khundii Gold Project (“Bayan Khundii”

or “BK”) in southwest Mongolia. The Report, entitled ‘Bayan Khundii Gold Project Feasibility Study, NI 43-

101 Technical Report’, dated August 31, 2020, with an effective date of July 20, 2020, was prepared in

accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101’) by a

consortium of International and Mongolian firms, coordinated by Roma Oil and Mining Associates Limited

(“Roma”). The Report is available under the Company’s profile at www.sedar.com and on the Company’s

website at www.erdene.com.

Quotes from the Company:

"The Bayan Khundii feasibility study results confirm the robust returns of this project in its base case, and

the significant upside from ongoing district-wide exploration and rising gold prices,” said Peter Akerley,

Erdene’s President and CEO. “As a low-capex, low-opex project within an emerging gold district, Bayan

Khundii offers investors and stakeholders strong leverage to gold as we seek to grow the resource base

and move towards the goal of first production in early 2022.”

“An 18,000 metre exploration program is underway, currently focused on upside in the Bayan Khundii area

and initial drilling of the recently discovered Dark Horse prospect,” continued Mr. Akerley. “This program

has the potential to add to Bayan Khundii reserves and to expand resources across the broader district.”

“On the development side, we have commenced the construction readiness, detailed design work and

permitting processes required to move rapidly to construction,” concluded Mr. Akerley. “With the proceeds

of the recently closed C$20 million private placement, led by a strategic investment from Eric Sprott, and

the engagement of HCF International Advisers Limited ("HCF"), with a mandate to secure project debt

financing, we have visibility to the required funding.”
