Sirios Inc.: Tilly Grades 4.36% Mo, 6.4% Cu, 201 g/t Ag, 0.6 g/t Au and 0.22% Bi

MONTREAL, QUEBEC--(Marketwire - Nov. 19, 2007) - SIRIOS RESOURCES INC. (TSX VENTURE:SOI) discovered numerous new areas with molybdenum mineralization on its Tilly property, James Bay, Quebec. Ten new areas, including six main ones each comprising many molybdenum-copper-silver-gold-(bismuth) showings, were discovered in granitic rocks in addition to the showings previously found by Sirios. A total of 327 grab rock samples were collected from 602 surveyed outcrops with grades up to 4.36% Mo, 6.4% Cu, 201 g/t Ag, 0.6 g/t Au and 0.22% Bi. Seventy-five samples graded either more than 394 ppm (or 0.039%) molybdenum or 357 ppm copper.

The new showings are commonly associated with, or close to, hydrothermal breccias varying in length from 600 to 1,000 meters and from 50 to 100 meters in width. They comprise mainly molybdenum and/or chalcopyrite mineralization associated with quartz veinlets or veins or finely disseminated. These mineralizations are part of a significant porphyry system.

The President of Sirios, Dominique Doucet, states: "The numerous mineral occurrences on the property show high potential for the discovery of a low grade but high tonnage world class porphyry deposit similar to Spinifex Ridge in Australia (469 Mt : 0.06% Mo, 0.09% Cu, 1.7 g/t Ag) and Climax in Colorado, USA (907 Mt : 0.24% Mo)". (i)Mt: Million of tonne.

The significant assay results by area are given below while the main mineralized areas are summarized in the following table :

sign./total : number of significant samples with Mo greater than 394 ppm or Cu greater than 357 ppm out of the total number of samples collected in the related area.

During the summer and fall of 2007 the following work was completed on the property :

-185 km of 200 meters-spaced line cutting ever all the property,

-systematic prospecting and mapping, 362 rock samples collected including 35 with pending results, -induced polarization (I.P.) geophysical survey (dipole-dipole and gradient) totaling 185 km.; pending results.
