Smith Ranch-Highland

North America map showing location of Smith Ranch-Highland and North Butte properties

We operate Smith Ranch and Highland as a combined operation. Each has its own processing facility, but the Smith Ranch central plant currently processes all the uranium, including uranium from satellite facilities. The Highland plant is currently idle. Together, they form the largest uranium production facility in the United States.

2013 update


Production this year was 6% higher than our forecast and significantly higher than 2012 production, with new mine units contributing to production at Smith Ranch-Highland in 2013, as well as the startup of the North Butte satellite.

Our North Butte satellite began production during the second quarter and produced 300,000 pounds in 2013. We expect to ramp up to a target annual production rate of more than 700,000 pounds per year by 2015 from the North Butte satellite operation. We continue to seek regulatory approvals to proceed with the rest of our expansion plans.


The regulators continue to review our licence renewal application. We are allowed to continue with all previously approved activities during the licence renewal process.

Planning for the future


In 2014, we expect to produce 2.0 million pounds.
