Orano Canada Inc.

McClean Lake Mill

The Orano operated McClean Lake mill is a unique facility – it is the most technologically advanced mill in the world for the processing of high-grade uranium ore without dilution. The McClean Lake mill opened in 1999 and underwent a period of care and maintenance from 2010 to 2014. In October, 2014, coinciding with our celebration of 50 years in Canada, the McClean Lake restart began with the processing of all ore from the newly opened Cigar Lake mine located 80 kilometres away. Since its original commissioning, the mill has achieved a production of over 123 million pounds of uranium concentrate. In 2019, the mill processed 18 million pounds of uranium concentrate.

Orano Canada Inc.

We have been exploring for uranium, developing uranium mines and producing uranium concentrate in Canada for over 50 years. Headquartered in Saskatoon, Saskatchewan, Orano is a leading producer of uranium in Canada.

Orano Canada is a subsidiary of the Orano group, an international nuclear energy company headquartered in France with 16,000 employees worldwide.

Northern Presence

With our activities concentrated in northern Saskatchewan, Orano continues to show its commitment to the people of the North – to their prosperity and priorities, especially health, safety and the environment. Our activities also result in socio-economic benefits for northern communities through training and employment opportunities, and the purchase of goods and services from northern businesses.


Environmental Stewardship

Protecting the environment and people is a priority at Orano. We are committed to responsible environmental stewardship throughout the life of our projects, from our exploration, to operation and decommissioning. This commitment relies on sound environmental studies and constant monitoring. Emissions from operations at the McClean Lake mill remain well below regulatory limits. Orano also takes great care in managing the now decommissioned Cluff Lake mine in northwest Saskatchewan.
