MINERAL RESOURCE UPDATE

The updated mineral resource estimate includes drill data as of September 18, 2020. It includes an additional 213 drill holes for a total of 60,865 m drilled since August 6, 2019 (close-out date for September 25, 2019 resource). Of which, an additional 122 new drill holes in Kiena Deep for a total of 35,280 m in the update of the Kiena Deep Zones. The drilling information was used to update the interpretation of the geologic model, geometry of the mineralized zones and domains resulting in a higher degree of confidence in the resource estimate.

The 2019 Preliminary Economic Assessment ("PEA") has not been updated in light of the 2020 MRE. The 2020 MRE does not have a negative impact on or otherwise adversely affect the mineral resource inventory that formed the basis of the 2019 PEA.

COVID-19

The health and safety of our employees, contractors, vendors, and consultants is the Company's top priority. In response to the COVID-19 outbreak, Wesdome has adopted all public health guidelines regarding safety measures and protocols at all of its mine operations and corporate offices. In addition, our internal COVID-19 Taskforce continues to monitor developments and implement policies and programs intended to protect those who are engaged in business with the Company.

Through care and planning, to date the Company has successfully maintained operations, however there can be no assurance that this will continue despite our best efforts. Future conditions may warrant reduced or suspended production activities which could negatively impact our ability to maintain projected timelines and objectives. Consequently, the Company's actual future production and production guidance is subject to higher levels of risk than usual. We are continuing to closely monitor the situation and will provide updates as they become available.

Cautionary Statements Regarding Estimates of Mineral Resources

This news release uses the terms measured, indicated and inferred resources as a relative measure of the level of confidence in the resource estimate. Readers are cautioned that mineral resources are not economic mineral reserves and that the economic viability of resources that are not mineral reserves has not been demonstrated. The estimate of mineral resources may be materially affected by geology, environmental, permitting, legal, title, socio-political, marketing or other relevant issues. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to an indicated or measured mineral resource category. The mineral resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum's "CIM Definition Standards on Mineral Resources and Mineral Reserves" incorporated by reference into NI 43-101. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for Preliminary Assessment as defined under NI 43-101. Readers are cautioned not to assume that further work on the stated resources will lead to mineral reserves that can be mined economically.

Cautionary Note to United States Investors Concerning Estimates of Reserves and Resources

The mineral reserve and resource estimates reported in this news release were prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") as required by Canadian securities regulatory authorities. The United States Securities and Exchange Commission (the "SEC") applies different standards in order to classify and report mineralization. This news release uses the terms "measured", "indicated" and "inferred" mineral resources, as required by NI 43-101. Readers are advised that although such terms are recognized and required by Canadian securities regulations, the SEC does not recognize such terms. Canadian standards differ significantly from the requirements of the SEC. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories constitute or will ever be converted into mineral reserves. In addition, "inferred" mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource exists, is economically or legally mineable or will ever be upgraded to a higher category of mineral resource.
