SIRIOS/TILLY Project (Mo-Cu) : Update on the First Stage of the Drilling Program

MONTREAL, QUEBEC--(Marketwire - Nov. 20, 2008) - SIRIOS RESOURCES INC. (TSX VENTURE:SOI) announces the results of the first stage of the drilling program undertaken on its TILLY property in James Bay, Quebec. Nine diamond drill holes totalling 1,160 meters allowed the testing of three geophysical targets as well as three surface showings. The best obtained grades come from the Spotty Moly showing : 0.05% Mo over 11 m in hole #8 and a section of 25 m at 0.06% Cu including 0.1% Cu over 5 m in hole #7. On the Tide showing, hole #9 yielded 0.04% Mo over 5 m and 0.1% over 20 m. These drill holes intersected chalcopyrite and molybdenite ( less than1%) mineralizations within altered granitic rocks located at the border of a kilometric potassic alteration zone interpreted as the core of a porphyry system.

Four drill holes (#2 to #5) intersected copper anomalous granitic rocks with grades from 0.02% to 0.03% on continuous intervals varying from 50 m to 150 m, and a few isolated less than 0.2% molybdenum grades over 1 m upto 2 m . One drill hole yielded no significant results.

During the 2008 fieldwork, the outline of a kilometric potassic alteration zone was identified around which copper and molybdenum showings, associated with porphyry dykes, were discovered. These new features associated with the numerous (10) major hydrothermal breccias already recorded, confirm the nature and the significance of the TILLY property polymetallic porphyry system.

Twenty or so first priority geological and geophysical targets remain untested. A second phase of drilling is planned for 2009 to test those targets. The geophysical targets have been selected based on more than one hundred geophysical anomalies initially recommended by the geophysicists during the 2007 and 2008 magnetometric, radiometric and induced polarization ground surveys.

All half-core samples were sent to ALS-Chemex Val D'Or laboratory, using atomic absorption technique for gold and ICP for all other elements. Industry-standard quality controls were applied, including blank, standard and duplicate inserts in the sample series.
