The Daneros Mine is a fully-developed and permitted underground mine located in the White Canyon Mining district in San Juan County, Utah, Approximately 70 miles west of the White Mesa Mill. It was acquired by Denison Mines in 2011 as part of the White Canyon takeoverfor A$57m. As market conditions warrant, the Daneros Mine is well positioned for a rapid restart.

The mine operated from 2009 until October 2012 when it was placed on standby. Initially White Canyon Uranium Limited brought the mine into production sending ore to the White Mesa Mill under a toll milling agreement with Denison.  Energy Fuels acquired the mine in 2012.

Tabular zones of moderate to high-grade uranium mineralization hosted in the Shinarump Conglomerate Member of the Triassic Chinle Formation. Mineralization localized within channel sandstones beneath organic-rich sediments.

Exploration Potential

Significant drilling occurred in 2007 and 2008 to confirm historical resources. There is potential for additional resources, as indicated by historical mineral resources at the Lark and Royal. Higher-grade mineralization occurs in paleochannels that are more than 20 ft. thick. Identifying and targeting these areas may lead to discovery of further mineralization.

Planned Work

An 8-hole program totalling 7,200 ft will commence immediately following completion of the Tony M program and will focus on areas outside of the historic resource estimate.
