Mr. Duncan Middlemiss, President and CEO, commented, "Wesdome remains focused on advancing our vision of building Canada's next mid-tier gold producer. The opportunity to advance Moss Lake and bolster our already strong balance sheet, all while retaining meaningful exposure to the project through a strategic equity position as the largest shareholder of Goldshore allows the Company to remain fully focused on our underground high-grade gold mining expertise. This year is pivotal as Wesdome expects to deliver the Kiena Complex into commercial production, expand operations at Eagle as well as move forward on aggressive surface and underground exploration programs at both sites."

The Transaction is subject to customary closing conditions for a transaction of this nature, including completion of the proposed reverse take-over business combination between Goldshore and Sierra Madre Developments Inc. (resulting in the listing of Goldshore on the TSX Venture Exchange) and receipt of required regulatory approvals.

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.
