30 Years of Innovation

Since its inception CMAC-Thyssen Mining Group has been known for its innovative projects inside the province of Quebec and in the world at large. Our willingness and ability to apply our expertise and meet every challenge head-on is the hallmark of a team that refuses to stand still.


Building the Foundation

Claude MacDonald, visionary and driller by profession hailing from Malartic, Quebec, establishes CMAC Long Hole Drilling in 1995, a three-employee drilling company with, as sole client, Agnico-Eagle’s La Ronde division.


Invest in the future

In order to meet the specific needs of the region’s narrow vein mines, CMAC – in collaboration with Agnico-Eagle Mines – invests heavily into research and development to design, develop, and commercialize drilling equipment tailored for the operational challenges that are unique to this type of deposit. A manufacturing division is created, its products tested within Agnico-Eagle’s various mines and the range of services offered by CMAC expands into both drilling and mining development.

Innovation as Driver for Growth

As a result of the company’s focus on research and development the prototype of the CMAC 2001 drill is released. Versatile, robust, powerful, and featuring a unique positioning table allowing for a wider drilling radius, the new modular drill is able to be dismantled easily for use in captive mining sites.
