MONTREAL, March 24, 2021 (GLOBE NEWSWIRE) — The management of Sirios Resources Inc. (TSXV: SOI) is pleased to announce the signing of a reverse circulation drilling contract with Boart Longyear. The drill contract will include a minimum 7,500 metre program to commence this summer on the Cheechoo gold property in Eeyou Istchee James Bay, Quebec.

Reverse Circulation Drilling

The campaign will be carried out using reverse circulation drilling (RC drilling), a reliable drilling technology widely used throughout the world. RC drilling is particularly advantageous for definition drilling in advanced projects targeting near-surface deposits. RC drills are significantly faster and less expensive than diamond drills, resulting in more holes drilled during this campaign and at a lower cost per meter.

Due to the larger diameter of the drilled hole, RC drilling allows for larger, more representative samples, which is particularly more suitable for gold deposits where mineralization is erratically distributed (nugget effect). Sampling is also faster, since the RC cuttings are sent from the drill rig to the laboratory with fewer intermediate steps, such as eliminating delays related to core sawing.

On the Cheechoo project, RC drilling will allow us to achieve our objective of deposit definition by providing reliable geological data in a more timely and cost-effective manner.

Campaign Objective

The objective of this summer's drilling program will be to better define the Cheechoo deposit and subsequently initiate a new resource estimate update (starting in 2022). This update is expected to convert a significant amount of the inferred resources to indicated resources. Improving the classification of the project's gold resources will allow us to improve the market valuation of the Cheechoo deposit as well as taking the project to a more advanced stage by completing a Preliminary Economic Assessment (PEA).

About the Cheechoo Property

The Cheechoo gold property, wholly-owned by Sirios, is located in Eeyou Istchee James Bay, Quebec, less than 9 km from Newmont’s Eleonore gold mine. The latest resource estimate for the Cheechoo project (October 2020) estimated an inferred resource of 2.0 million ounces of gold contained in 93.0 million tonnes of rock at an average grade of 0.65 g/t Au, with significant potential to increase this resource.¹
