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.”
