First Reconnaissance Research on DIOS Uranium Chat Brun Project
Yields 0,083% Uranium Oxide in Outcropping Rocks

MONTREAL, QUEBEC--(Marketwire - Oct. 30, 2008) - DIOS EXPLORATION (TSX VENTURE:DOS) just received the first outcropping rock samples results from a two-day reconnaissance on its CHAT BRUN uranium property in the LaGuiche Basin, Quebec, Canada. Ten grab-samples from rock outcrops were collected by Dios geologists on their first visit of this new property. Two biotite-rich samples, located one kilometre apart, returned values of 710 ppm U. They were analysed at the Val d'Or ALS CHEMEX laboratory. Field readings of 1,000 to 10,500 counts per seconds (radiation solution RS-125) with U/Th ratios between 1,0 and 5,8 were observed on the property.

The CHAT BRUN property is centered on a uranium lake bottom sediment anomaly cluster from SDBJ data including 5 samples over 100 ppm U AA (parts per million uranium analyzed by atomic absorption): 375, 239, 193, 180, 174 ppm U AA over a 8 km by 5 km area. Available government mapping suggests that the CHAT BRUN property is underlain by LaGuiche biotite paragneiss injected by east-west striking tonalitic-pegmatitic dykes-sills. This environment is favourable to a Rossing-type (8% of the world production) large volume uranium model amenable to open cast mining.

The CHAT BRUN property is totalling about 60 square-kilometers and located in James Bay, Quebec. The property is owned 100% by DIOS EXPLORATION. The DIOS' team is of the opinion it has uncovered a new uranium district in Quebec, with all its new uranium discoveries in the Opinaca area.

The PAM property is underlain by LaGuiche paragneisses (metasediments), granitic migmatites as well as deformed dioritic intrusives along several fold-hinges. The PAM project is also located just south of the regional Opinaca River structural corridor, along the same trend hosting the Opinaca Nord uranium project (about 10 km to the west). Rossing-type high tonnage uranium as well as classic vein-type models may be considered in association with numerous anatexis granites occurring within metasediments of the LaGuiche Basin.

DIOS is in a good financial position and has the funds necessary to pursue its exploration programs. The quarterly financial statements and management report for the quarter ending September 30, 2008 are filed on sedar. For more information, please look at the new website www.diosexplo.com.
