SOI Sirios Resources Inc

Management of SIRIOS RESOURCES INC. (TSX-V: SOI) is pleased to announce the start of a 1,200-metre diamond drilling program on Sirios' Cheechoo gold property in Eeyou Istchee, James Bay, Quebec. The proposed holes will test the lateral and depth continuity of gold mineralization discovered in the 2022 trenches (Figure 1), from which an interval grading 2.65 g/t Au over 11.0 m (Figure 2) was obtained. This gold mineralization, identified in meta-sedimentary rocks, was also intersected in holes #67, 129 and 269, which included an interval of 0.9 g/t Au over 15.7 m (ref.: press release dated 04/24/2018).

Dominique Doucet, President of Sirios, stated: "We are very excited to follow up on the excellent results we initially obtained on surface in the area we refer to as 'Meta-Sediments' outside the Cheechoo deposit. Gold mineralization in this area is hosted in meta-greyackes, the same host rock as the nearby Éléonore mine, suggesting the potential to discover not only a new zone, but perhaps even another gold deposit."
