FOR IMMEDIATE RELEASE

U.S. SUPREME COURT DECLINES REQUEST FOR FURTHER

REVIEW OF EAGLE MOUNTAIN LAND EXCHANGE

PALM SPRINGS, CA (March 28, 2011) — Kaiser Ventures LLC and Mine Reclamation, LLC announced today that the U.S. Supreme Court did not accept their petition seeking review of an adverse November 2009 U.S. 9^th Circuit Court of Appeals decision which will send Kaiser’s completed land exchange for the Eagle Mountain landfill project back for further review by the U. S. Bureau of Land Management (“BLM”). Kaiser’s and Mine Reclamation’s petition was one of approximately 200 petitions that the U.S. Supreme Court announced today that it would not further review.

The U.S. 9^th Circuit Court of Appeals concluded that there were three deficiencies in the process for the completed land exchange between Kaiser and the BLM and that additional documentation will be required before the land exchange is confirmed allowing the landfill project to proceed. Kaiser and Mine Reclamation are in the process of completing their evaluation of the documentation necessary to address the deficiencies and will be working with the BLM to identify the best means to proceed.

Rick Stoddard, Kaiser’s Chief Executive Officer and Chairman of Mine Reclamation said, “We are disappointed that our petition for review was not granted by the U.S. Supreme Court. We are, however, grateful that the U.S. Solicitor General, on behalf of the U.S. Department of Interior, agreed that the 9^th Circuit Court of Appeals decision was wrong.” Mr. Stoddard also said that: “Since the 9^th Circuit Court of Appeals affirmed the BLM’s determination that the public interest is well served by the land exchange as required by law, it is just a matter of working with the BLM to identify the best path that may be implemented to fix the identified deficiencies.”

U.S. SUPREME COURT DECLINES TO REVIEW - ADVERSE DECISION OF THE

U.S. 9^TH CIRCUIT COURT OF APPEALS

2-2-2-2-2

The Coachella Valley Economic Partnership, Los Angeles County Sanitation Districts and others each filed briefs before the Supreme Court urging further review of the adverse 9^th Circuit decision. The Economic Partnership brief argued the adverse Eagle Mountain decision impacts more than just the Eagle Mountain landfill project as such decision is already being used to challenge proposed solar energy projects in California.

The positive impacts of the Eagle Mountain landfill go far beyond being an extremely sound environmental disposal site. Riverside County will receive millions in new revenue to fund public services. The entire region benefits from the hundreds of new, family wage jobs that will be created as well as the provision of tens of millions of dollars to fund the Coachella Valley multi-species habitat conservation plan and for environmental research in Joshua Tree National Park.

The Eagle Mountain landfill project is located in the remote eastern Riverside County desert and is proposed to accept up to 20,000 tons of non-hazardous solid waste per day for 50 years.
