Allied Nevada Gold Corp


	Environmental As of December 31, 2010, the Company has all required approvals for the facilities (heap leach pads, crushers, over burden storage, etc.) to mine and process 50 million tons of ore. In early 2012, the Company expects to receive approvals to increase the capacity to process an additional 350 million tons of ore, increasing the total permitted capacity to approximately 400 million tons. At the expanded mining rate, this indicates that operations can continue for a minimum of 6 years. Allied Nevada expects to receive permits in 2012 that will allow mining in Boneyard, Bay Area, Camel and extensions to Brimstone. New areas for overburden storage will be developed north of the Bay/Boneyard areas, and on the east side of the Crofoot pad. These newly permitted areas will allow for the development of three to five mining faces at the same time resulting in both accelerated waste removal and ore extraction. A project of the size and magnitude of the mill expansion project will require extensive federal and state environmental permits in order to be constructed and operated. The project will also require a site wide Environmental Impact Statement (“EIS”). Preliminary work required for the EIS, such as base line water sampling, archaeology surveys, etc. began late in 2009. The scoping study assumes receipt of all required state and federal permits to construct and operate the sulfide mine and plant in three years from the submittal of the applications. Receipt of required federal and state permits to begin construction of the milling facilities is expected to take approximately three years.
