Thyssen Mining’s roots date back to shaft sinking in Germany in the late 1800’s. Thyssen Schachtbau GmbH in Germany sank its first shaft in the 1870’ and first employed ground freezing techniques in 1905. Thyssen’s freezing expertise was significant in establishing its reputation in mine shaft construction.

In the 1960’s, the Saskatchewan potash industry required expertise to allow shaft sinking through geological formations containing extremely high volumes of water. Thyssen Schachtbau exported its knowledge to Canada and ultimately established Thyssen Mining’s headquarters in Regina, Saskatchewan, sinking nine mine shafts during its initial expansionary phase into Canada.

From the 1970’s to the end of the 20th century, Thyssen Mining diversified into a full-service underground mining contractor in North America. Thyssen Mining became the dominant mining contractor in the Saskatchewan uranium sector and expanded its operations to include both the Canadian and American mining markets. In 1997, the formation of Mudjatik Thyssen Mining Joint Venture created a highly successful model to allow First Nations and Métis communities to participate in economic development opportunities in the northern Saskatchewan uranium mines.
