SIRIOS: Uranium Prospecting Results on OPINACA NORD

MONTREAL, QUEBEC--(Marketwire - May 5, 2009) - SIRIOS RESOURCES INC. (TSX VENTURE:SOI) reports the results from the fall 2008 prospecting program undertaken by partner DIOS EXPLORATION (TSX VENTURE:DOS) on SIRIOS' OPINACA NORD uranium property. The property is located in the LaGuiche metasedimentary Basin, in the James Bay area, Quebec; it consists of 685 claims covering 340 km2. DIOS may earn a 50% interest by investing $1.35 M over a 5 year period. SIRIOS holds approximately 4% of the share capital of DIOS.

Fieldwork undertaken by DIOS in 2007, led to the discovery of a radioactive zone reaching 800 meters long (targets A1, A2, A3) with values of 0.617%, 0.162% and 0.103% uranium oxides (U308). The 2009 results return three samples with 0.174%, 0.120%, and 0.078% U3O8 values, from eleven new grab samples collected on the outcropping A1-2-3 zone. The mineralization consists of disseminated uranophane and uraninite (uranium minerals) within rocks called migmatites (paleosomes). Another radioactive area (target D1) was also investigated, but none of the new grab samples returned significant values (less than 0.01% U3O8).

Moreover, the Ministere des Ressources Naturelles et de la Faune du Quebec reported the discovery of emeralds in the area, notably on the OPINACA NORD property. Microprobe analysis is required to verify whether these green beryl minerals are chromium bearing (sensu stricto emeralds). These green beryls should also be assessed for their quality and gem potential. The OPINACA NORD property is located in a geological environment favourable to emeralds, with the proximity of ultramafic intrusive bodies, which could have provided chromium, necessary for emerald formation.

The samples were collected and prepared by IOS Geoscientific Services Inc of Saguenay, Quebec. They were assayed at the Saskatchewan Research Council.
