MONTREAL, QUEBEC–(Marketwire – April 9, 2008) – Sirios Resources (TSX VENTURE:SOI) partner, Dios Exploration, has reviewed the findings of a low-level aerial spectrometric survey recently completed on their UPINOR uranium property. A new map shows a large geophysical anomaly, with clusters of high background ratios of uranium thorium (U:Th) with values of up to 3.0 times the norm. Mr. Camille St-Hilaire, an independent geophysicist, commented that the uranium thorium ratios were much higher in the 5-km area that has yet to be prospected. The A-Zone anomaly is a linear, lithological, east-west striking with an approximate length of 5 km and a variable width of between 0.2 to 0.5 km.

Dios management is of the opinion that this is a significant uranium discovery. Furthermore, reviewing the Uranium Thorium Ratio Map, it is felt that the discovered anomaly zone could extend beyond the linear 5-km strike in an elliptical sweep from the A-Zone into a north-westerly direction returning in a south-easterly direction (refer to the on-line Uranium/Thorium Ratio Map). This discovery bears similarities to the Namibian Rossing deposit in the occurrence of mineralization associated with anatexis pegmatite dyke-swarms, in close proximity, making it amenable to opencast, low-cost mining. The Rossing mine, part of the Rio Tinto group located in Namibia, in southern Africa, accounts for 7.5% of the world’s supply of uranium oxide. It has been producing uranium oxide for the last 30 years.

This updates the results of 31 basement-rock samples taken last fall (2007) on the A-Zone. The samples, found in a 2000-metre long area, summarizes in the assay as follows: 16 % had greater than 0.20% U3O8, 32% had greater than 0.10% U3O8, 29% had values of between 0.05% and 0.097% U3O8, and 16% had values of between 0.02% and 0.05% U3O8. Put into perspective, the Rossing mine produced, over the last 30 years, approximately 165 M lbs of uranium oxide from an overall grade of 0.034%. The basement-rock samples assay table is available in a Dios press release dated February 26th, 2008.

The UPINOR uranium property totals over 500 claims and is located about 30 km north of the Opinaca Nord uranium project, about 50 km south of the Trans-Taiga road, James Bay, Quebec. The UPINOR project is held by SIRIOS in a 50-50 partnership with DIOS EXPLORATION INC., and DIOS is the operator.
