Intrepid Adjusts 2008 Potash Production and Cost of Goods Sold Guidance

Intrepid Potash, Inc. (NYSE:IPI) announced today that it is adjusting its full-year production guidance for potash downward by 20,000 tons or approximately two (2) percent. The adjustment is a result of two items. First, the Company has made the decision to extend its turnaround schedule to include approximately 3 - 5 additional days of planned downtime during the turnaround cycle. The Company's decision to invest in additional reliability enhancement projects associated with its electrical systems at its Carlsbad, NM operations is expected to enhance overall reliability and reduce future unscheduled downtime. Work that will be performed during the turnaround period has been expanded to include coordinated improvements performed by the local power provider, after mutual agreement with the Company, to upgrade the regional system that serves our Carlsbad facilities and the hiring of three major electrical firms to work concurrently during the extended turnaround to renovate and upgrade the electrical systems in our surface plants and underground mine operations. The second item was lower than expected recovery rates experienced at the Company's West Mine during the third quarter due primarily to the decreased performance of a binding chemical purchased for use in the flotation circuit. The Company is actively working to address this item.

"The decision to take proactive steps to upgrade the electrical systems is designed to benefit the Company for the long-term and enhance overall reliability of production at our Carlsbad operations," noted Bob Jornayvaz, Chairman and Chief Executive Officer.

The impact of these items is an adjusted full-year production range of 850,000 - 870,000 short tons of potash and has the effect of increasing the full-year potash production cost of goods sold forecast by $15 per short ton to $155 - $165 per short ton. The Company is also reporting that it expects its net realized price per ton of potash for the third quarter to be approximately $620 - $640 per short ton.
