Sirios Launches Drilling Campaign at Cheechoo

Sirios Resources Inc. has successfully initiated Phase 1 of its ambitious 25,000-metre drilling campaign at the Cheechoo gold deposit in Quebec's Eeyou Istchee James Bay region. The company has received all necessary permits, including the critical Authorization for Impact-Causing Exploration Work (ATI), and has mobilized two drill rigs to site with a third scheduled for deployment by the end of June. This represents a significant milestone for the company as it advances its flagship gold project.

A notable technological advancement in this campaign is the deployment of a Laser-Induced Breakdown Spectroscopy (LIBS) unit for real-time drill core analysis directly on site. This cutting-edge technology, installed in modules designed by Sirios, is expected to enhance the accuracy of core logging and improve understanding of the deposit's geology and metallurgy. The company plans to analyze both new drill cores from the summer campaign and conduct a comprehensive review of existing core samples.

The successful launch of this drilling program follows Sirios' December 2025 acquisition of OVI Mining, which the company described as a milestone in its corporate history. Additionally, Sirios has completed a helicopter-borne magnetic survey at its Fagnant gold project, which will inform future field exploration strategies. The company's ability to commence drilling in early June as planned demonstrates strong project management capabilities and positions Sirios well for a productive exploration season.

For the broader Quebec mining sector, this drilling campaign represents continued investment and exploration activity in the prolific James Bay gold district. The integration of advanced analytical technologies like LIBS at the drill site reflects the industry's ongoing push toward more efficient and data-rich exploration methodologies, potentially setting new standards for junior exploration companies operating in the region.
