Third drill rig active on the Cheechoo gold property

MONTREAL (QUEBEC) – Management of Sirios is pleased to announce that a third drill rig

has recently been added on the Cheechoo gold property in order to accelerate the progress of the

drilling campaign initiated in January. Seventeen drill holes have been completed, totalling

approximately 3,500 metres. More than 10,000 metres of drilling are expected to be completed in

this current campaign.

The option of additional drilling crews is now possible due to important improvements made to

the camp in the past few months. A new and larger exploration camp at Cheechoo allow us to

accommodate up to 50 workers, each with individual rooms. This compares to the previous camp

where shared tents allowed a maximum capacity of 20 workers. These substantial improvements

are inline with Sirios’ goal of developing a larger and more advanced exploration project at

Cheechoo.

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.
