Calypso Provides Update on Drilling Program on Campesino Norte Property and 2008 Field Work

NOT FOR DISSEMINATION IN THE UNITED STATES OR THROUGH US NEWSWIRE SERVICES

CALYPSO URANIUM CORP. (TSX VENTURE:CLP) ("Calypso "or the "Company") provided an
update to the news release dated December 10, 2008 in regard to progress on the
3,000 to 5,000 meter drilling campaign at its wholly-owned Campesino Norte
uranium-vanadium-copper project in Neuquen Province, Argentina. The Campesino
Norte Project consists of 48,229 hectares, being approximately 482 square
kilometres, in the Neuquen Basin Cretaceous continental stratigraphy. There are
a total of six clusters of paleo-channels in outcrop, occurring along a 20
kilometre corridor. Each cluster has multiple channels, and all are mineralized
with uranium, vanadium, and copper. The occurrence of these clusters in a
corridor strongly suggests the location of a persistent river channel through
time, a setting typical of sandstone-hosted uranium districts world-wide.


The drilling is now at hole number 25 on the Petrosaurios target. Fences of
holes spaced 50 meters apart and covering up to a kilometre of width, are being
drilled to depths between 30 and 50 meters. Geochemical assay results are not
yet available. The protocol for sampling the intervals has been established by
the Company's VP Exploration and Geophysicist, and select intervals will be sent
for geochemical assay. The protocol includes QAQC control and the Company has
selected Alex Stewart Argentina S.A. as the lab to analyse the samples. The
Company anticipates completing a further 35 drill holes for the minimum 3,000
meter program, and to complete drilling by the middle of June. The Company may
determine to expand the drill program up to 5,000 meters.


Mr. Roney Long, President of Calypso commented; "Once initiated the Campesino
Norte drilling program has been proceeding extremely well. The visual results to
date have been very encouraging and we will release the assay results as soon as
they are available."


The Company's subsidiary, Energia Mineral Inc. SA is completing the field season
in the Province of Chubut, where the Company holds 151,459 hectares, being
approximately 1,514 square kilometres. Numerous outcropping uranium shows have
been visited and sampled by the Company's field crews. A dedicated landman has
been visiting the ranches and arranging access and this program has been
progressing well. The results of the field work indicate the San Jorge basin,
where the Cerro Solo uranium deposit is located, represents a highly prospective
area for uranium with uranium mineralization observed on surface as a well as
additional indicators to be explored by follow up exploration programs.
