Prospect Global Permitting Update: Arizona Department of Environmental Quality Sends Notice of Administrative Completeness

DENVER, Feb. 25, 2013

The Company expects to receive a decision from the ADEQ by the end of this year.

In addition to the Air Quality Control Permit application, Prospect Global, through its wholly-owned subsidiary, American West Potash LLC, also has filed its Draft Mineral Development Report with the Arizona State Land Department as part of an application to convert certain of its state exploration permits into mineral leases.

The Company also is finalizing its application for the Aquifer Protection Permit, which it plans to submit to the ADEQ in the second quarter of 2013.

A copy of ADEQ "completeness" letter will be available on the Prospect Global website (www.prospectgri.com) in the near future.
