Major Drilling Announces Normal Course Issuer Bid

MONCTON, March 23, 2023 - Major Drilling Group International Inc. (TSX: MDI) ("Major Drilling" or the "Company"), one of the world's largest drilling services companies primarily serving the mining industry, announced today that the Toronto Stock Exchange ("TSX") has accepted its notice of intention to make a normal course issuer bid (the "NCIB Program") to purchase outstanding common shares of Major Drilling (the "Common Shares") on the open market in accordance with the rules of the TSX. Pursuant to the NCIB Program, Major Drilling may purchase, from time to time, in aggregate up to 4,150,251 Common Shares (being approximately 5% of the 83,005,029 issued and outstanding Common Shares of Major Drilling as of March 15, 2023) over a 12-month period commencing on March 27, 2023 and terminating on March 26, 2024.

Any repurchases under the NCIB Program will be made in Canada through the facilities of the TSX and/or alternative Canadian trading systems. Major Drilling will pay the prevailing market price at the time of purchase. The actual number of Common Shares repurchased under the NCIB Program and the timing of such repurchases will be at Major Drilling's discretion and shall be subject to the limitations set out in the TSX Company Manual. Daily purchases on the TSX will be limited to 27,000 Common Shares, other than block purchase exceptions, which represents 25% of the average daily trading volume of the Common Shares on the TSX for the six-month period ending February 28, 2023, being 108,001 Common Shares. The Common Shares repurchased by Major Drilling will be cancelled. Management and the Board of Directors of Major Drilling believe that the underlying value of Major Drilling may not be reflected in the market price of the Common Shares from time to time and that, accordingly, the purchase of Common Shares will increase the proportionate interest in Major Drilling of, and be advantageous to, all remaining shareholders of Major Drilling.

Major Drilling has not purchased any Common Shares pursuant to a NCIB Program during the last 12 months.
