Preliminary Significant Results on Opinaca North: Dios Hits 0.62%U308 in the Exposed Rocks

MONTREAL, QUEBEC--(Marketwire - Feb. 28, 2008) - DIOS EXPLORATION (TSX VENTURE:DOS) received a series of rock samples results from exposed outcrops on its OPINACA NORTH uranium property located about 30 kilometers east of the Goldcorp Eleonore multi-million ounces gold deposit, Quebec, Canada. The OPINACA NORTH property covers 300 sq. kilometer (576 claims) encompassing the Laguiche sedimentary Basin in the easily accessible James Bay area, where roads, hydropower and facilities are available, keeping exploration costs very competitive. Preliminary outcrop rock samples taken last Fall on the property were assayed at the laboratory of the Saskatchewan Research Council and results recently returned are of significant value, up to 0.618 % U3O8, as well as 0.162%, 0.142%, 0.136%, 0.103% U3O8. Work completed up to now consisted mainly of large scale ground prospecting targeting the uranium lake sediment anomaly clusters identified from a detailed survey and follow-up work is planned to fully evaluate the size of the radioactive zones and to systematically investigate a 25 km-long uranium lake sediment anomalies trend.

DIOS outlined three kilometric size radioactive outcrop areas on the Opinaca Nord project. The NW anomaly returned 1,300 to 20,550 cps (radioactive counts per second) over 1,000 m by 300 m. The NE anomaly located 20 km due east of the NW one, is characterized by 1,000 to 8,500 cps over a minimum area of 500 m by 300 m. The SW anomaly, located about 3 km south of the NE one, showed 1,500 to 16,000 cps over 2,000 m by 300 m. All radioactive outcrop areas are underlain by anatexis granite or white pegmatitic granite injected along a regional east-west trending structural corridor. Targeting the area for uranium from conceptual research design, DIOS had signed an option agreement to acquire a 50% interest in the property from Sirios Resources for exploration expenditures of 1,25 M$ in May over a 5-year period and yearly instalments of 25,000 $. The first year commitment has already been met and DIOS is operator.

From thirty-eight outcrop samples taken during the Fall reconnaissance prospecting campaign, 5 returned values higher than 0.10% U3O8, 7 had values between 0.03% and 0.10% U3O8 and 8 between 0.01 and 0.03% U3O8. Field prospecting was completed by an independent firm, IOS Geoscientist Services.
