Calypso Uranium Corp. (TSX VENTURE: CLP) ("Calypso" or the "Company") -

Calypso President J. Stephen Barley is pleased to announce that Cameco Global Exploration Ltd. ("Cameco") has elected to proceed with the second year option under the Joint Venture Option Agreement with Energia Mineral Inc. ("Energia Mineral"), Calypso's wholly owned subsidiary in Argentina. Mr. Barley stated: "We look forward to continuing the relationship with Cameco in regard to the exploration of Energia Mineral's highly prospective uranium properties in Argentina. The second year budget of $3 million will continue and enhance the efforts from the initial year of the joint program."

Mr. Guillermo Pensado, President of Energia Mineral and VP Exploration of Calypso commented: "We have exploration projects across a broad area with high geological potential for uranium and one of the benefits of partnering with a major company such as Cameco is that we can apply a thorough and methodical approach to the exploration of the potential of those properties and confirm our geological models."

Priorities under the first year of the joint exploration program included drill programs at the Campesino Norte and Central Block Projects in the Neuquen Basin, from which preliminary results will soon be available. The agreed second year exploration program will include a follow up drill program at Central Block, the first potential uranium in situ recovery project being explored in Argentina, as well as an intensive exploration program on the Company's properties in the San Jorge Basin.

The Company's President J. Stephen Barley stated: "The unfortunate and devastating tsunami in Japan earlier in 2011 caused a dampening effect on the worldwide uranium industry at all levels. Calypso believes the longer term outlook for uranium remains strong due to the global need for efficient and industrial-scale energy sources that can meet the demands of a growing world population while reducing negative impacts on the atmosphere. We will continue to explore our current properties in Argentina with Cameco and will consider approaches for new prospects in key areas of the country. Calypso remains well funded with over $4 million in available working capital. We are assessing methods of advancing our projects in the province of Mendoza currently delayed pending legislative approvals and our Sage Creek project located in Wyoming where we have a 50% interest in a large and well located land package. In addition we are reviewing other opportunities within and outside of Argentina."
