Description Bell Copper focuses on the development of copper mines in North America. The company's primary project consists of the La Balsa copper and iron ore site in Michoacan, Mexico (which is not yet in production). The company's portfolio of development and exploration projects also includes copper properties in Arizona in the US. These include its Kabba project in the Mohave Desert and its Sombrero Butte project near the Mexican border. Bell Copper was formed in 2008 by the acquisition of Grandcru Resources and Rogue River Resources by Bell Resources.
