SIRIOS RESOURCES INC.: Up to 0.229% U3O8 Obtained From New Zones at Surface on the UPINOR Property

MONTREAL, QUEBEC--(Marketwire - Feb. 18, 2009) - SIRIOS RESOURCES INC. (TSX VENTURE:SOI) announces the results of the fall exploration program on its UPINOR uranium property, in James Bay, Quebec.

Last fall, a mapping-prospecting program was completed to investigate the new A-South, South, NW zones and the extensions of the pluri-kilometric radioactive A1 zone. A total of 120 grab samples were collected on the property and 25 (or 21%) assayed more than 0.05% U3O8, including 7 (6%) more than 0.10 % U3O8. The best assay was 0.229 % U3O8.

Half (61) of these samples were collected on the new radioactive A South sub-zone extending over a five-kilometre strike length, just west-southwest of the A zone that was partially test-drilled last summer. Twelve samples (20%) assayed greater than 0.05% U3O8 including five (8%) greater than 0.10% U3O8, up to 0.229% U3O8.

Another twenty-seven samples came from another new radioactive (South) zone that extends itself over seven kilometres in length, and is located about ten kilometres southeast of the previous zones. Eight samples (30%) yield over 0.05% U3O8, up to 0.138% U308.

Sixteen samples on the new radioactive NW zone returned five assays (31%) greater than 0.05% U308, up to 0.103% U3O8. The remaining samples were collected on the D target that appears to be the southern limb of the folded A1 and A South zones, and no values greater than 0.05% U308 were returned. The fall 2008 results are shown on the map available at http://media3.marketwire.com/docs/DOS_map.pdf.

UPINOR uranium mineralization consists of disseminated uraninite, uranophane, apatite, molybdenite and biotite in metric low-dipping pegmatite-alaskite sills/dykes injected in paragneiss. The samples were collected and prepared by IOS Services Geoscientifiques Inc. of Saguenay, Quebec. They were assayed at the Saskatchewan Research Council laboratory.

The UPINOR property covers 450 km2 in the Laguiche Basin, James Bay, Quebec. It is equally held and explored in partnership with Dios Exploration Inc. (TSX VENTURE:DOS) who manages the exploration program. SIRIOS holds approximately 4% of the share capital of DIOS.
