Description Uranerz is on the hunt for uranium. Uranerz Energy Corporation is a mining and exploration company with uranium properties in Canada and the US. Although none of the company's sites are in production, its properties in the Powder River Basin of northeast Wyoming show the most promise for a future mineral claim. The Canadian properties are set up as joint ventures with the partner companies bearing the brunt of exploration costs. Uranerz Energy Corporation was founded in 1999 by former executives of Uranerz Exploration and Mining Limited, which was bought by Cameco in 1998.
