Press Release

Halifax, Nova Scotia 

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, 2021 and to provide an update on its Khundii Gold District, including its Bayan Khundii Gold Project (“Bayan Khundii” or “BK”). This release should be read in conjunction with the Company’s 2021 Financial Statements and MD&A, available on the Company’s website or SEDAR.

Quotes from the Company:

“During 2021, we executed upon our strategic objectives of expanding the Khundii Gold District, while advancing the Bayan Khundii Gold Project towards development,” said Peter Akerley, Erdene’s President and CEO. “Our blind-top discovery at the Ulaan Southeast gold prospect and the expansion of the 1.5-kilometre Dark Horse Mane gold mineralized trend demonstrate the scale potential of the Khundii-Ulaan system within the Khundii Gold District. We are well on our way to confirming our two million ounce gold equivalent resource target in 2022, and see the potential to add resources beyond this target.”

“We also made solid progress advancing Bayan Khundii towards a construction decision, despite the continued impact of COVID-19,” concluded Mr. Akerley. “Over the past twelve months we completed 90% of the project’s design, secured several key permits, including the Mongolian Detailed Environmental Impact Assessment, and advanced project finance with Export Development Canada and other financiers. The Company plans to commence preparatory site works in the coming months, with full construction ramping up in mid- 2022. However, the Company is monitoring the impact of COVID-19 on the availability and costs of key inputs and will provide a more fulsome update on schedule and budget in the coming months.”

  • Exploration and evaluation expenditures, including capitalized expenditures, totaled $12,391,867 for the year ended December 31, 2021, compared to $9,276,028 for the prior year, due to increased exploration work as the Company drilled nearly 20,000 metres in the current year, compared to approximately 15,000 metres in the prior year, as well as incremental expenditures on the Bayan Khundii Gold Project Detailed Engineering & Design work and Construction Readiness activities (including deposits on long-lead time items), that exceeded costs associated with the Feasibility Study and Detailed Engineering & Design work in the prior year.

  • Non-cash, change in fair value expenses of $8,412,081 and interest expenses of $1,661,960 in the prior year were attributable to a convertible loan held by the European Bank for Reconstruction and Development (“EBRD”), which was converted in October 2020, resulting in EBRD becoming one of Erdene’s largest shareholders

COVID-19 Update

In late January 2020, the Government of Mongolia instituted limitations on public gatherings, suspended in-person classroom learning, and implemented international border controls in response to COVID-19. The Canadian Government adopted similar measures in March 2020, as did most governments globally during 2020. With the first confirmed cases of community transmission of COVID-19 in November 2020, the Government of Mongolia further restricted the movement of people and the delivery of goods and services. While restrictions were eased in early 2021, precautionary measures were subsequently reintroduced in late Q1 2021 following an increase in the number of reported cases in Mongolia.

In March 2021, Bayankhongor Province, where Erdene’s projects are located, reported its first confirmed case of community transmission of COVID-19, leading to the imposition of restrictions on the movement of people within and to/from the province. Furthermore, in late June 2021, Bayankhongor province and the sub-province of Shinejinst, the communities in which Erdene operates, imposed states of emergency due to worsening community spread of COVID-19 in the area. Although the Company temporarily halted field work in late June in response, Company staff and contractors returned to site in early August 2021 to commence follow-up exploration work, which has continued without interruption due to COVID since this date. Additionally, Canadian and International staff and consultants resumed travel to Mongolia in Q3 2021. On February 14, 2022, the Government of Mongolia fully reopened its borders to vaccinated international travelers, allowing the Company’s staff and key contractors to travel to the Country with minimal disruption.

However, Mongolia continues to see disruptions at its land borders with China, given the latter’s zero COVID policies. These disruptions have impacted the availability and prices of industrial and consumer goods required for the construction of the Bayan Khundii Gold Project. Although the impact of COVID-19 on the Company’s operations has been modest to date, COVID-19 has the potential to further delay or increase the costs of the Bayan Khundii Development. The Company is monitoring the situation and assessing the impact on the Bayan Khundii Gold Project construction schedule and budget. Erdene does not intend to ramp up to full construction until there is certainty that supplies can readily be imported to Mongolia. The Company will provide further details on the impact of COVID- 19 on its operations and the Bayan Khundii Gold Project as they become available.

Erdene is working with Mongolian and Canadian authorities to implement and maintain controls to protect the health and well-being of its workers as well as the communities in which the Company operates.
