DENVER -- October 2, 2013

Prospect Global Resources Inc. (NASDAQ: PGRX) (“Prospect Global” or the
“Company”) is pleased to announce that it has received its Air Quality Control
Permit (“Air Permit”) for the construction and operation of an underground
potash mine and surface processing facilities from the Arizona Department of
Environmental Quality (“ADEQ”).

The mine and facilities are to be located approximately 30 miles southeast of
the city of Holbrook, AZ in Apache County.

The Air Permit is for the emissions from a 2.2 million ton per annum, two
train processing plant and related mine production as contemplated by the
Company’s Preliminary Economic Assessment completed in December 2011. Prospect
Global is continuing to evaluate building only one of the two processing
trains and related mine output with correspondingly reduced emissions as
analyzed in the Company’s Pre-Feasibility Study.

The Company is on track to finish its infill drilling program over the next
two weeks and complete an updated 43-101 resource report by the end of 2013.
