Calypso Uranium Announces the Launch of an Exploration Drilling Program in the Neuquen Basin and the Signing of an Option Agreement for Three Properties at Its La Pintada Property

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/09/11 -- CALYPSO URANIUM CORP. (TSX VENTURE: CLP) ("Calypso" or the "Company") - Calypso President Stephen Barley is pleased to announce that the Company's wholly owned subsidiary in Argentina, Energia Mineral Inc., is launching its exploration drilling program in the Neuquen Basin following the Declarations of Environmental Impact for the Central Block and Campesino Norte Projects. The Company is also pleased to announce that Eneria Mineral has signed a Mining Exploration and Purchase Option Agreement with Miranda S.A., for three key properties surrounding the Company's La Pintada property.

Exploration Program in the Neuquen Basin

"We are pleased to be able to launch an intensive exploration program in the Neuquen Basin," said Stephen Barley, President and CEO of Calypso. "It is a key element of Calypso's joint venture agreement with Cameco and we are eager to advance with this drill program, at the first potential in-situ recovery (ISR) exploration project in Argentina." In September 2010, Calypso signed an Option Agreement with Cameco to explore and develop uranium projects in Argentina through Energia Mineral.

Guillermo Pensado, Vice President Exploration for Calypso and President of Energia Mineral, said, "The Central Block and Campesino Norte exploration programs are a priority at this stage and represent an investment of about $2,000,000 for the first phase. We have an expert team in place that will be initiating the drilling program in the near future, working closely with the local community and local suppliers."

The Declarations of Environmental Impact represent the approval of the exploration drilling programs presented for the Campesino Norte and Central Block Projects for the next two years, and were issued by the Sub-Secretariat for the Environment for the Province of Neuquen, under Disposition Nos. 140-11 and 153-11, on April 15 and April 29, respectively. Based on national and provincial regulations, the approval is founded on technical assessments by the Provincial Directorates of Environment, of Mining, and of Water Resources.

The Central Block project is an ISR project located along the Chihuidos High range in the Neuquen oil & gas producing basin and represents the most significant ISR project under exploration in Argentina. The approved exploration program includes drilling of 20,000 meters by reverse circulation (RC) that are planned to be drilled in different phases. The first phase of drilling will be initiated in the near future and the aim of the program is to confirm the most potentially mineralized horizons interpreted by field mapping and historical oil & gas geological and geophysical data. The Campesino Norte follow-up exploration program includes a 10,000 meter RC drill program that will be initiated with a first phase to the southwest of the mineralized paleo-channel intercepted during the drill fences completed in 2008.

Mining Exploration and Purchase Option Agreement with Miranda S.A.

The Mining Exploration and Purchase Option Agreement with Miranda S.A. is for three properties covering approximately 14,500ha or 1,450km2 in the Sierra Pintada District in the Province of Mendoza. The properties comprise several radiometric anomalies surrounding existing Energia Mineral properties and border the south edge of the Sierra Pintada uranium deposit. The Agreement was signed by Energia Mineral on March 31, 2011, and the properties will be covered by the joint venture exploration agreement with Cameco.

"These three properties are strategically located respective to Energia Mineral's La Pintada Project near the Sierra Pintada deposit. Our first step is to begin work on the Environmental Impact Report required by law in order to obtain the approvals for prospective activities," said Pensado.

Under the terms of the Agreement, Energia Mineral will lead prospecting and exploration activities, and Miranda grants Energia Mineral the option to purchase 100% of the Properties at any time five years and six months as from the date of execution of the Agreement.
