Sirios Launches Drilling Campaign at Cheechoo
Sirios begins drilling at the Cheechoo deposit in the James Bay gold camp to expand its regional exploration footprint.

Executive Summary
- Sirios Resources has secured all necessary regulatory permits, specifically the Authorization for Impact-Causing Exploration Work (ATI), to commence Phase 1 drilling at its flagship Cheechoo gold project.
- Two drill rigs are currently on-site, with a third rig scheduled to arrive by late June 2026.
- The company is deploying a Laser-Induced Breakdown Spectroscopy (LIBS) unit for real-time, on-site core analysis to improve geological and metallurgical data accuracy.
- A helicopter-borne magnetic survey at the Fagnant gold project has been completed to guide future exploration strategy.
- Drilling operations officially commenced in early June 2026, aligning with the company's previously announced 2026 exploration program.
Material Impact
- The launch of the Cheechoo drilling campaign is a direct execution of the fully funded 2026 exploration program announced on April 1, 2026, which outlined ~25,000m of expansion drilling to update the resource estimate.
- This news is a routine, expected follow-up to prior announcements. It confirms management's operational capability to secure permits, mobilize equipment, and adhere to the stated timeline.
- The cash runway remains robust following the $25 million LIFE offering (March 2026) and $3.47 million in warrant/option exercises (May 2026), removing near-term financing overhangs.
- While positive, the market has already priced in the execution of this drill program. The news does not introduce new material upside or downside but validates the company's progress toward its H1 2027 PEA target.
