Sirios intersects 10.5 g/t Au over 10.6 m and 15.7 g/t Au over 8.7 m in Cheechoo

Drill Results

TSX-V: SOI November 13, 2018

Sirios intersects 10.5 g/t Au over 10.6 m and 15.7 g/t Au over 8.7 m in Cheechoo

MONTREAL (QUEBEC) – Management of SIRIOS (TSX -V: SOI) is pleased to announce

assay results of six drill holes, totalling 1,780 metres, undertaken on the Cheechoo gold property.

The six drill holes are part of the larger drill program that will complete the 50 m -drill hole grid

pattern of the Main Area, where the current dimensions are approximately 500 m by 500 m. In

addition to demonstrating the continuity of the larger auriferous halo, pluri-metric high-grade gold

intersections are continuously being intersected within the halo:

• Drill hole #191: 10.5 g/t Au over 10.6 m, including 44.1 g/t Au over 1.0 m;

• Drill hole #183: 15.7 g/t Au over 8.7 m, including 146.9 g/t Au over 0.8 m;

• Drill hole #189: 1.2 g/t Au over 41.0 m.

Additional significant gold intersections were intersected in drill holes as indicated in the table

below.

Drill hole #189 confirms the vertical continuity of the auriferous zone that runs along the tonalite-

meta-sediment contact. Section 189 shows a thickness of about 50 meters in this area. Beyond the

contact, the gold mineralization is distributed within the tonalite around a zone of intense alteration

as shown on sections 183 and 189. The section of drill holes 186, 189 and 191 illustrate the

presence of a significant g old bearing material within 130 meters of the surface as shown in the

section.

Assay results are still pending for the last three holes out of 58 totalling 15,720 metres completed

in 2018.

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 was described by Sirios personnel at the Cheechoo exploration camp. The drill

core was 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 was

followed by integrating blanks and certified reference standards to the core sample sequence. The

samples were assayed for gold by fire assay with an atomic absorption finish by Actlabs in Ste -

Germaine-Boulé. Samples assaying greater than 2 g/t Au as well as drill core samples with visible

gold were assayed by fire assay with metallic sieve based on a 1 kg sample.
