Quotes from the Company:

“The first quarter of 2023 was another productive period for Erdene as we made significant progress advancing our Bayan Khundii (“BK”) Gold Project towards construction,” said Peter Akerley, Erdene’s President and CEO. “With the recent close of the second stage of our MMC Strategic Alliance, we are launching early construction works and expect to make a full construction decision in mid-2023.”

“In Q1 we also ramped up exploration in the KMD, with three rigs currently conducting mineral exploration, hydrogeological reserve exploration, and geotechnical drilling, including exploratory drilling at our Zuun Mod molybdenum-copper project,” continued Mr. Akerley. “With robust molybdenum prices and a strong outlook for copper demand supporting the green energy transition, we plan to continue to unlock the value of the Zuun Mod. Following the completion of the first phase of work at Zuun Mod, expansion and exploration drilling will test for high-grade gold, targeting resource extensions and new prospects near the planned BK open pits.”

Corporate

• Entered Strategic Alliance with MMC and closed the first two tranches receiving US$10 million of funding
  • MMC to invest US$40 million for a 50% equity interest in Erdene’s Mongolian subsidiary that holds the Khundii and Altan Nar mining licenses and the Ulaan exploration license
  • Erdene retains 50% of EM and a 5.0% NSR royalty on production from the Khundii, Altan Nar and Ulaan licenses, as well as any properties acquired within 5 kilometres, beyond the first 400,000 ounces of gold recovered, as well as 100% interest in ZM
  • Closed the first stage of the Alliance in January 2023 and the second stage in early May 2023

• Progressed BK Project Finance with EDC and other international financial institutions

  • Exploration and evaluation expenditures, including capitalized expenditures, totaled $1,437,182 for the three months ended March 31, 2023, compared to $2,904,572 for the comparative prior year period as reduced field activity and design and engineering work, as well as the payment of a deposit on the elution circuit in early 2022, and the timing of payments under the local cooperation agreement more than offset current period expenditures to update the FS
  • Corporate and administrative expenses totaled $580,111 for the three months ended March 31, 2023, compared to $445,446 for the three months ended March 31, 2022, with the year on year increase primarily due to expenditures associated with the negotiation and announcement of the MMC Strategic Alliance as well as higher administrative salaries due to cost of living adjustments

Update on Strategic Alliance with MMC

In January 2023, the Company announced a Strategic Alliance with MMC to develop BK. MMC is the largest, private producer and exporter of high-quality washed hard coking coal in Mongolia. MMC owns and operates the Ukhaa Khudag and the Baruun Naran open pit coking coal mines, both located in Umnugovi Aimag (South Gobi Province), Mongolia. The shares of MMC are listed on the main board of the Hong Kong Stock Exchange (HKEx: 975), and the company has a current market capitalization of approximately US$400 million.

MMC’s largest beneficial shareholder is MCS Group, one of Mongolia’s leading conglomerates. MCS has operated in Mongolia for 30 years, and has operations in engineering, energy, communications, property, mining, consumer goods, health, and hospitality. MCS employs approximately 10,000 staff in Mongolia and is one of the Country’s largest private taxpayers.

Erdene’s exploration and pre-development capabilities, MMC’s mining and operational expertise and the ability of MCS Group companies to provide complimentary infrastructure and energy solutions creates the ideal platform to develop the KMD for the benefit for all stakeholders.

Under the terms of the Strategic Alliance, MMC will invest US$40 million for a 50% interest in Erdene’s Mongolian subsidiary, Erdene Mongol LLC (“EM”), which holds the Khundii and Altan Nar mining licenses and the Ulaan exploration license through a three-stage transaction. Erdene will retain a 50% equity interest in EM as well as a 5% Net Smelter Return royalty on all production from the Khundii, Altan Nar and Ulaan licenses, as well as any properties acquired within five kilometres of these licenses, after the first 400,000 ounces of gold recovered. Erdene maintains a 100% interest in the Zuun Mod copper-molybdenum project.

The first stage of the Strategic Alliance was completed in mid-January 2023, with MMC advancing US$5 million by way of a convertible promissory note to finance an updated Feasibility Study and Life of Mine Plan for the BK Gold Project. Since this time, Glogex Consulting, a leading Mongolian geology and mining consulting firm, has assisted Erdene and MMC in preparing an internal update of the BK Feasibility Study completed in mid 2020.

With the completion of the internal update study in late April, MMC advanced the second tranche of US$5 million to EM on May 2, completing the second stage. These funds will be used to complete the 2023 FS and to undertake early construction works and exploration.

The third stage of the partnership will see MMC invest a further US$30 million once EM has reached a construction decision, providing equity capital for the BK Gold Project, expected in Q3 2023.
