Calypso Earns 50% Interest and Enters Into Joint Venture on Wyoming Potential in Situ Recovery Uranium Exploration Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 3, 2010) -


CALYPSO URANIUM CORP. (TSX VENTURE:CLP) ("Calypso" or the "Company") is pleased to announce the Company and Earth Minerals International Inc. have amended their option agreement dated June 18, 2008 and Calypso through its wholly owned US subsidiary Sage Creek Minerals Inc. has now earned a 50% interest in 403 unpatented lode mineral claims with in situ recovery ("ISR") potential located in Converse County, Wyoming known as the Sage Creek claims. The two companies have entered into a joint venture agreement with Calypso being the initial operator.

The Sage Creek claims are in the prolific southern Powder River Basin area of the State of Wyoming. The Smith Ranch uranium ISR facility operated by Power Resources Inc., a wholly owned subsidiary of Cameco Corporation, is immediately adjacent to the east of the Sage Creek claims. The Smith Ranch ISR operation is one of the largest uranium ISR fields in production in the world. Calypso and its partner are now assessing the manner in which they will advance exploration on the claims.

The Company re-elected Stephen Barley, Kurt Bordian, Robert Pendreigh, and Omar Beretta as directors at the Shareholders Meeting held on August 26th. Regrettably, Dr. Jon P. Thorson has determined to not stand for re-election due to other business commitments, however the Company is very pleased Dr. Thorson has agreed to remain as a technical advisor to the Company.
