Sirios intersects its targets with 187.0 g/t Au over 0.8 m and 106.0 g/t Au over 1.3 m

at Cheechoo

MONTREAL – Management of SIRIOS (TSX-V: SOI) is pleased to announce assays results for six drill

holes of the winter drilling campaign recently completed on the Cheechoo gold property at Eeyou Istchee

James Bay, Quebec. Drill holes #240 and 245 intersected high- grade gold zones, Vein 112 and Jordi, as

described below:

Vein 112

CH19-240: 25.5 g/t Au over 6.8 m, including 187.0 g/t Au over 0.8 m

CH19-245: 18.9 g/t Au over 1.0 m

Jordi Zone

CH19-240: 26.7 g/t Au over 1.2 m

CH19-245: 106.0 g/t Au over 1.3 m

Drill holes #240 and 245 targeted Vein 112, at a vertical depth of 300 m and approximately forty metres

on each side of the discovery hole #112, that yielded 41.0 g/t Au over 8.0 m (press release 14/02/2018).

These drill holes demonstrate the continuity of Vein 112, with similar veins intersected in drill holes #098

and #125E, confirming the lateral extension of the vein over 110 metres in a N-S direction. Vein 112

remains open in all directions.

Drill holes #240 and 245 have also intersected the Jordi Z one at a vertical depth of approximately 50

metres, confirming the interpretation of the geological model. This zone has been intersected by numerous

drill holes, with grades up to 867.1 g/t Au over 0.5 m (press releases 04/03/2018, 24/04/2018).

Significant results were obtained in all recent drill holes, most notably in drill hole #239 with 0.6 g/t Au

over 77 metres in the Contact Zone and #221 with 2.6 g/t Au over 15.5 metres.

Significant results of the six drill holes are presented in the table below.

The winter 2019 drilling campaign on Cheechoo included 47 NQ drill holes, for a total of 11,322 meters

drilled. The assay results are expected very shortly for the remaining ten holes.

Sirios’100% owned Cheechoo property is located in the Eeyou Istchee James Bay region of Quebec,

approximately 800 km north of Montreal, 200 km east of Wemindji and less than 10 km from

Goldcorp’s Éléonore gold mine.

Assay quality control

All NQ drill core are logged by Sirios personnel at the Cheechoo exploration camp. The drill core is then

sent to Rouyn-Noranda to be sawed in half, with one half sent to a commercial laboratory for assaying

and other half kept for future reference. A strict QA/QC program i s in place by integrating blanks and

certified reference standards to the core sample sequence. The samples are assayed for gold by fire assay

with an atomic absorption finish by ALS in Val -d’Or. Samples assaying greater than 2 g/t Au as well as

drill core samples with visible gold are assayed by fire assay with metallic sieve on a 1 kg sample.
