As of Might 2015, electroniqueskit Energy Fuels was preparing to mine uranium at its Canyon mine, a deposit on US Forest Service land, six miles from the south rim of the Grand Canyon.

Burns and Steele discovered the Central Lake deposits, which were developed into Bicroft Mine, whereas Shore's prospect grew to become the Faraday Mine.
