Update of Sirios’ activities in the Eeyou Istchee James Bay Region, Quebec

Montreal (Quebec) – The management of Sirios Resources Inc. (TSX-V: SOI) announces that

the suspension of its exploration activities initiated on June 4 in the Eeyou Istchee James Bay

region is continuing. This suspension will continue as long as the restriction of access to the public

forest is maintained by the Government of Quebec in order to prevent new fires. The management

of Sirios wish es to indicate that they greatly appreciate the efforts made by the various

organizations involved in the fight against the current forest fires as well as the solidarity of aid

and support to the local communities and victims of this situation.

Before the halt of fieldwork, the Sirios exploration team completed the following tasks on its

Cheechoo gold property:

- Collection of 10 composite samples , totaling 570 kg for mineralogical studies and

metallurgical recovery. These samples came from drill core intervals and new channel samples

targeting representative areas with various tungsten grades previously observed in tonalite or meta-

sedimentary rocks. The objective of these tests is to verify whether tungsten , in association with

the Cheechoo gold mineralization, could become a by -product of interest, thereby increasing the

value of the deposit.

- Locating on the ground, using differential GPS, future sites for exploration trenching to

be carried out this summer east of the Cheechoo gold deposit.

- Collecting and shipping of a hundred drill core samples from various intervals of previous

drilling in order to test the new Photon Assay analysis technique at the MSALABS laboratory in

Val-d'Or.

About Cheechoo Property

The Cheechoo gold property is 100% owned by Sirios and consists of 306 claims covering an area

of 157 km2, divided into three non -contiguous blocks. It is located in Eeyou Istchee James Bay,

Quebec, less than 9 km from Newmont’s Eleonore gold mine and is easily accessible by all-season

roads. The property hosts the Cheechoo gold deposit. It’s most recent resource estimate, based on an

open pit constrained model, includes an indicated resource of 1.4 million ounces of gold

contained in 46.3 million tonnes at an average grade of 0.94 g/t Au, and an inferred resource

of 0.5 million ounces of gold contained in 21.1 million tonnes at an average grade of 0.73 g/t

Au with significant potential to increase this resource (BBA, PLR Resources, P-L. Richard, P.
