Quotes from the Company:

"During the third quarter, we executed upon our two 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. "Expansion of the South Ulaan gold prospect demonstrates the scale potential of the Khundii-Ulaan system underlying our Khundii Gold District. Erdene has a 3,000-metre program scheduled for late 2021, in support of our 2 million ounce resource target in 2022."

"We are also steadily progressing Bayan Khundii towards a construction decision, despite the uncertainty created by COVID-19," continued Mr. Akerley. "The Company intends to commence preparatory works in Q4 2021, with full construction ramping up in early 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."

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 since this date. Additionally, Canadian and International staff and consultants resumed travel to Mongolia in Q3 2021.

Mongolia continues to experience a significant number of COVID-19 cases, which has led to disruptions at the Country's land borders with China. Such closures 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 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 people can freely travel, and 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.

All Erdene employees have received at least two doses of COVID-19 vaccine and many staff have received a third booster shot. Erdene is working with Mongolian and Canadian authorities to maintain control measures to protect the health and well-being of its workers as well as the communities in which the Company operates.
