MONTREAL, QUEBEC–(CCNMatthews – June 7, 2006) – SIRIOS RESOURCES INC. (TSX VENTURE:SOI) received recently the final bottom lake sediment survey report on its wholly owned OPINACA NORD property. Two main gold anomalies were confirmed and detailed by a second series of analysis by neutron activation and several other checks. This property is located in the OPINACA area where Goldcorp recently completed the acquisition of the ELEONORE gold deposit, James Bay, Quebec, Canada.

The latest results outlined a well defined gold anomaly in the north-eastern part of the property. Anomalous gold is associated with arsenic, silver, bismuth and selenium. It is located up-ice of a lake bottom gold anomaly of 96 ppb Au (SDBJ, 1975 survey). This anomaly follows glacial dispersion and shows size and intensity similar to the one observed down ice of the ELEONORE deposit.

The second gold-silver-tellurium anomaly forms a glacial dispersal train suggesting a source in the western part of the property in the vicinity of a major east-west structural lineament.

“The sediments of the OPINACA NORD property have a relatively high background in respect to gold, with more than 47% of the samples above the detection limit. The survey includes 26 samples with grades above the 90th percentile (regional population), with 98th as highest rank…” (R. Girard, 2006).

The lake sediment geochemical report on the OPINACA NORD property was produced by Mr. Rejean Girard, Geo. and Qualified Person of IOS Services Geoscientifiques inc (IOS) from Chicoutimi, who also supervised the sampling program.

SIRIOS plans a strong 2006 summer exploration programme with a $ 800,000 budget for its wholly-owned properties in the Opinaca region. The OPINACA NORD property totals 538 claims for 270 square-km (67,000 acres).

The survey, carried out in July 2005, comprises 183 samples in the scope of a regional campaign of 2,200 samples. The assays were completed by Activation Laboratories, Ancaster, Ontario. All samples were assayed for 59 elements by inductively coupled plasma mass spectrometry (ICP-MS) and for 34 elements by neutron activation. Quality control included the use of standards and duplicates by the contractor, assay standards, duplicates and blanks by the laboratory, as well as gold re-assay by fire assay with plasma finishing at ALS-Chemex for part of the samples.

Gold was initially assayed by ICP-MS with a detection limit of 0,5 ppb, by neutron activation with a detection limit of 1 ppb, as well as for some samples by fire assay with a detection limit of 1 ppb. Considering the multiplicity of analytical methods used and the problems associated with nugget effect distribution, gold grades herein reported represent the average of the different assay methods including duplicates, with a cut-off of 10 ppb for the ICP-MS assay method. The average weighted grade is 1.1 ppb and the anomalous threshold is 5 ppb, in comparison with a regional background below the detection limit. Eight samples exceeded an average weighted grade between 5 and 11 ppb, which is considered anomalous. About 10% of the ICP-MS individual assays exceeded the 10 ppb cut-off, up to 82.4 ppb.
