Intrepid Potash NM, LLC Eddy County, NM

In operation since the 1930s (West Mine) and the 1960s (East Mine), Intrepid’s
Mines produce Muriate of Potash and Sulfate of Potash Magnesia. The North
Facility converts compactor feed from the West Mine to standard-sized product.

Intrepid is the largest potash mine in Carlsbad, NM and the largest producer of
potash in the U.S. Pettigrew has been a consistent team member for
Intrepid and their design and construction teams for over 10 years.
Current projects are highlighted below.

HB Solar Solution Mine
The HB Project proposes to use solution mining and solar evaporation to
extract potash already leased by Intrepid from previously mined areas. This
project would safely and economically allow maximum recovery of potash ore
that was unable to be extracted from previous conventional underground

The project would entail a 12 to 18 month construction phase of the following
extraction wells with 37 miles of associated pipelines (primarily on federal and
state land), 520 acres of solar evaporation ponds on property owned by
at Intrepid’s West Facility.

With a projected 28-year mine life, the HB Project is expected to create
in federal and state royalties and an estimated $120 to $130 million in capital
construction expenditures; 150 to 200 local construction phase jobs and 30 to
potash at 150,000 – 200,000.

North Compaction Plant
The North compaction project is projected to be completed in two phases to
coincide with the anticipated production increases from the HB Solar Solution
mine and the expansion of mining and milling capacity at the West Mine, with
second phase planned for 2014. Total capital investment for the project is
expected to be approximately $95 to $100 million
