MONCTON, May 17, 2021 - Major Drilling Group International Inc.

The Acquisition will be immediately accretive on an earnings per share basis upon closing and provides Major Drilling a strong established presence in an important growth market.

Founded in 1990, McKay is considered a leader in reverse circulation drilling and operates a state-of-the-art fleet of 15 high-capacity reverse circulation rigs and five deep-hole diamond rigs with the most advanced hands-free remote operation and monitoring technology. McKay's fleet is at the very high end of specialized drilling equipment and includes support equipment and inventories necessary for its operation. The company is widely regarded as an innovator in the Australian mining industry and has long-standing relationships with Australia's largest mining companies. For the twelve-month period ending March 31, 2021, McKay generated revenue of approximately A$60 million and EBITDA (see "Non-IFRS Financial Measure") of approximately A$17 million.

"We are very excited to welcome McKay and its employees into the Major Drilling group. McKay has a well-established brand in Australia, particularly among mining majors, that is built on decades of delivering innovation and high-quality service to its clients," said Denis Larocque, President & CEO of Major Drilling. "This acquisition is a meaningful part of our growth strategy and provides us a strong foothold in an important growth market with high barriers to entry. In addition to a fleet of state-of-the-art rigs, we are acquiring a highly experienced team with local knowledge and long-standing relationships and existing contracts with leading blue chip mining companies. Finally, McKay and Major Drilling have very similar cultural and operational values and approaches, along with a strong commitment to sustainable resource development, consistent with our global ESG framework. With McKay's operational management team remaining in place, Major Drilling will be in a strong position to service customers in both reverse circulation and diamond drilling services in the very active Western Australian market."

"Joining Major Drilling represents an exciting new chapter for our business," said Mark McKay, Managing Director and Founder of McKay Drilling. "Since inception, McKay Drilling has set the standard in the Australian drilling industry. Denis and I agree that a company is only as good as the people working within it, and I'm proud of the fantastic team we have built. Major Drilling is a great fit for McKay in terms of capabilities, values, and culture, and I am looking forward to seeing our team grow to new heights together. I would like to thank all of our staff for their hard work and dedication in helping to grow our business to where it is today and our clients for their continued support. Major Drilling's global expertise and financial strength will allow us to continue our progress in developing innovative solutions for our industry and remain a leader in the Australian market for decades to come."

The purchase price for the Acquisition is an amount up to A$80 million, consisting of: (i) a cash payment of A$40 million payable on closing of the Acquisition, subject to working capital adjustments; (ii) A$15 million paid through the issuance of common shares of Major Drilling, valued based on the volume weighted average price of the common shares prior to closing, subject to TSX approval; and (iii) an earn out of up to A$25 million payable in cash over the next three years, based on the achievement of certain milestones. The cash portion of the purchase price is expected to be funded from Major Drilling's cash and existing debt facilities. The company is in discussions to increase its credit facilities to ensure it maintains the necessary flexibility to respond to current market conditions. The Acquisition is subject to customary closing conditions, including TSX approval, and is expected to close on or about June 1, 2021.

Non-IFRS Financial Measure

EBITDA is a non-IFRS financial measure that the Company believes is key, for both management and investors, in evaluating performance. EBITDA is commonly reported and widely used by investors and lending institutions as an indicator of a company's operating performance and ability to incur and service debt, and as a valuation metric. This measure does not have a standardized meaning prescribed by IFRS and therefore may not be comparable to similarly titled measures presented by other publicly traded companies and should not be construed as an alternative to other financial measures determined in accordance with IFRS.
