Challenges

• Supply power for future infrastructure expansions at the McArthur River mine operation, the world's largest high-grade uranium mine.
• Ore grades within the deposit are one hundred times the world average.
• The operation can produce more than 18 million pounds of uranium each year by mining only 150 to 200 tonnes of ore per day.

Solutions

• Basic engineering was completed and full EPCM services were provided for the design and construction of a 32 MW, 138 kV electrical substation and standby power-generation facility.
• The electrical substation was constructed, with power distribution and backup generation.
• Diesel storage tanks and power distribution throughout the mine site were included.
• Site preparation was initiated in 2012 and full construction was completed.

Highlights

• The McArthur River operation is the world's largest high-grade uranium mine.
• Site is located in a remote area of northern Saskatchewan.
• With challenging logistics and winter conditions, the project was executed with excellent local procurement and local contractor engagement.
• Completed below budget.
• Received the 2015 CIM Award for Project Safety.
