Normal Course Issuer Bid (“NCIB”) Update

GCM Mining provided an update today on its purchases of its common shares pursuant to its current NCIB which commenced in October 2021. During the period from December 6, 2021 through December 10, 2021, the Company purchased a total of 286,301 common shares at an average price of CA$5.20 per share with the total cost amounting to approximately CA$1.5 million. After the cancellation of these shares, the Company currently has a total of 98,241,274 common shares issued and outstanding.

The NCIB allows the Company to purchase for cancellation up to a total of 9,570,540 common shares of the Company over the 12-month term that will end on October 19, 2022, or such earlier date on which the maximum purchases under the NCIB have been completed. Purchases of common shares under the NCIB are being made through the facilities of the TSX or other alternative Canadian trading systems at the market price of the shares at the time of acquisition.

The Board of Directors and senior management of GCM Mining continue to believe that its common shares may from time to time trade in a price range that does not adequately reflect the value of the Company’s common shares in relation to its activities and future prospects. Accordingly, GCM Mining will continue to use its discretion to repurchase its common shares for cancellation under the NCIB.
