Major Drilling Group International Inc. is a Canadian-based mineral drilling services company that provides specialized drilling solutions primarily to the mining and mineral exploration industry. The company operates in the mineral drilling sector, with a focus on complex and technically demanding drilling projects that support exploration, mine development, and production activities. Its core services include surface and underground drilling, directional drilling, reverse circulation drilling, geotechnical drilling, environmental drilling, and specialized drilling programs for major mining companies and junior exploration firms.

The company is recognized for its specialization in difficult drilling environments, including remote locations, high-altitude regions, and technically complex geological formations. Major Drilling was founded in 1980 in New Brunswick, Canada, and expanded from a regional contractor into one of the world’s largest specialized drilling services providers through organic growth and acquisitions. Its operating model emphasizes operational safety, experienced crews, technical expertise, and a diversified geographic footprint that reduces exposure to any single commodity or jurisdiction.
