AREVA RESOURCES CANADA: FROM EXPLORATION TO RECLAMATION

Shaft at the Cigar Lake underground mine

AREVA Resources Canada Inc. specializes in uranium exploration and mining in Canada. The company operates mines and is a partner in several joint ventures. It has also successfully completed the first mining site decommissioning and reclamation project following depletion of the reserves.

Established in 1993, AREVA Resources Canada Inc. includes all of the group’s mining operations in Canada. It is based in Saskatoon, in the province of Saskatchewan. It employs nearly 425 people, 50% of whom are residents of Saskatchewan's north or are of Aboriginal ancestry.

Most of the company's active mining projects are located in Northern Saskatchewan. AREVA Resources Canada Inc.:

  • operates the McClean Lake mill;
  • is a partner in the McArthur and Cigar Lake mines. These two deposits, which are exceptional both in tonnage and in the high grade of the reserves, are currently considered to have the largest high-grade deposits in the world.

Discovering new deposits

Kiggavik project

Kiggavik project

AREVA Resources Canada Inc. is continuing its exploration activities (Midwest, Shea Creek, Kiggavik) in order to develop and diversify its long-term reserves. Exploration campaigns are conducted in the Athabasca Basin in the north of the province of Saskatchewan, and in Nunavut, two regions with high uranium potential. The pace at which these deposits are developed, and for which additional studies are needed, will depend on the level of uranium prices.

Midwest – AREVA Resources Canada owns 69% of this deposit, discovered in the eastern Athabasca Basin in 1978, and will operate it.

AREVA is also evaluating the possibility of developing an underground mine at its McClean Lake site.

Shea Creek – The Shea Creek deposit, located in the western Athabasca Basin, 13 kilometers south of the Cluff Lake site, is owned 51% by AREVA Resources Canada, which will also operate it.

Kiggavik – AREVA has a 64.8% interest in this deposit, discovered between 1974 and 1997 and will operate it. In 2014, AREVA Resources Canada filed the final Environmental Impact Statement for the Kiggavik project with the Nunavut Environmental Review Board..

In operation

McArthur River, the world’s largest high-grade deposit, is located about 620 kilometers north of Saskatoon. It is operated by Cameco Corporation, which holds a 69.8% interest in the venture, with AREVA Resources Canada holding the remaining 30.2%. The deposit was discovered in 1988 and mining began in 1999.

Remotely operated equipment is used to mine the deposit to prevent direct worker exposure to the high-grade ore.

The ore is processed at the Key Lake mill, located about 80 kilometers south of the mine. The mill is operated by Cameco Corporation, which has as majority interest of 83.3%, with AREVA Resources owning the remaining 16.7%.

Cigar Lake is the second largest high-grade uranium deposit in the world after McArthur River. The project is located 660 kilometers north of Saskatoon. It is operated by Cameco Corporation, which holds a 50% interest in the deposit. AREVA has a 37.1% stake. All of the ore extracted from the mine will be processed at the McClean Lake mill operated by AREVA. Mining began in March 2014. Cigar Lake will produce 6,900 tons of uranium a year when operating at full capacity.

Located 450 meters below the surface in unstable, water-saturated rock, the deposit was discovered in 1981 by AREVA. An innovative method – Jet Boring – has to be used to mine this deposit. With this method, which contributed to the development of a technology to strengthen the host rock by freezing, the ore is extracted using a high-pressure water jet.

The McClean Lake mill, which is operated by AREVA, is owned 70% by AREVA, 22.5% by Denison Mines Inc., and 7.5% by OURD (Canada) Co. Ltd.,  of Japan.

Located 700 kilometers north of Saskatoon, the McClean Lake mill is the most technologically advanced mill in the world for the processing of high-grade uranium ore.

The extension project currently under way will increase the mill’s annual production capacity to nearly 9,200 tons of uranium in 2015.

• Up to 75% of this capacity will be used to process all the ore from the Cigar Lake mine.

• The remaining 25% will be used for ore coming from other deposits.

The Cigar Lake and McClean Lake sites will then be together, the second-largest uranium producers in the world.

 

A MODEL EXAMPLE OF RECLAMATION

For more than 20 years starting in the 1980s, AREVA Resources Canada owned and operated the Cluff Lake deposit discovered in 1967. Mining operations ceased in 2002 following the depletion of the reserves. Today, Cluff Lake is considered a model mining reclamation program, which was planned from the very beginning of the project.

Site reclamation and mill dismantling were completed at the end of 2006. The site is being environmentally monitored today to track the change in conditions over time.

A company recognized for the quality of its environmental management practices

As for all of the group's entities, AREVA Resources Canada has an active risk management, natural resources consumption reduction and environmental protection policy.

AREVA Resources Canada Inc. deploys ISO 14001-compliant environmental management systems at all of its sites and for all of its operations. AREVA’s mining activities in Canada (exploration, mining and reclamation) are certified to this standard.

All of the sites have a monitoring system for air, water and wildlife, and numerous actions are taken to reduce the environmental footprint while the sites are in operation and after they are closed.
