Calypso Uranium Corp. is a mineral exploration company whose principal focus is the exploration and development of uranium properties in Argentina and recently in the United States.

Calypso Uranium is active in Argentina with large highly prospective uranium properties located in the provinces of Chubut, Mendoza and Neuquén. The Company is among the best positioned in Argentina to move from exploration to production given that several of the properties include resources previously confirmed by the Comisión Nacional de Energía Atómica (CNEA -- the Argentine national atomic energy commission).

Through our local subsidiary Energía Mineral (Inc.), Calypso has a fully staffed exploration office located in Mendoza working closely with local communities while operating to the highest national and international safety and environmental standards. To promote transparency and to build awareness and public understanding of uranium exploration, all our environmental impact reports (available by individual project) and our "Radiological Safety and Protection Guide for Uranium Exploration" are posted on our website.

While maintaining our principal focus on the development of our Argentine uranium projects, in June 2008, Calypso launched our activity in the United States, in Converse County, Wyoming. The Sage Creek claims are being operated by Sage Creek Minerals Inc., Calypso's wholly owned U.S. subsidiary.
