Sirios Resources Inc. (OTCQB: SIREF; TSXV: SOI) generates a steady flow of news centered on gold exploration and project advancement in the Eeyou Istchee James Bay region of Québec. As a Quebec-based mineral exploration company focused on high-potential gold properties, its disclosures cover technical milestones, financing activities and corporate developments that shape the outlook for its key projects.
Much of Sirios’ recent news flow relates to the Cheechoo Gold Project, described by the company as its flagship, 100%-owned asset. Updates include an NI 43-101 Mineral Resource Estimate for Cheechoo with both open-pit and underground components, recommendations for further work such as a preliminary economic assessment and additional drilling, and infrastructure improvements to the access road co-financed with the Government of Québec through the Société du Plan Nord.
Another major source of news is the Aquilon gold project, where Sirios operates under a funding arrangement with Sumitomo Metal Mining Canada. Releases have detailed the start and results of multi-thousand-metre diamond drilling programs, the discovery of a strongly anomalous gold halo in the western sector, and the integration of soil sampling, structural interpretation and drone magnetic surveys to define new targets.
Investors following SIREF news can also expect updates on private placements, warrant and option exercises, shareholder meeting results and board decisions, as well as information on the announced acquisition of OVI Mining Corp. and Sirios’ investor outreach efforts, including participation in resource investment conferences and third-party awareness campaigns. This news page brings these developments together so readers can track how exploration results, technical reports, financings and corporate actions affect Sirios’ gold projects over time.
Sirios Resources (SIREF) completed Phase 1 drilling at Cheechoo on September 28 and reported gold assay results. The latest assays cover 15 holes totaling 6,850 m. Hole CH26-337 returned 39.94 g/t gold over 6.5 m, including 129.00 g/t over 2.0 m; CH26-345 returned 9.07 g/t over 12.5 m, including 103.11 g/t over 1.0 m. A wider interval in CH26-334 returned 122.1 m at 0.43 g/t.
Phase 1 comprised 45 holes and 23,037.5 m. Visible gold was observed in 68 intervals across 18 holes, while holes with no significant results along the northern and northeastern resource margins mainly crossed barren paragneiss. Sirios has received nearly half the summer campaign’s results. Interval lengths are measured along drill holes, and true thicknesses remain unknown. The company plans approximately 12,000 m of Phase 2 drilling beginning in January 2027; its resource estimate is expected to begin in the coming weeks.
Sirios Resources (SIREF) approved a proposed 15-for-1 share consolidation and a change of its name to Sirios Mining.
As of September 22, 2026, Sirios had 672,943,910 common shares issued and outstanding. If completed, the consolidation would leave approximately 44,862,927, subject to rounding. Both changes require shareholder approval at the October 30, 2026 meeting and compliance with TSX Venture Exchange requirements. Outstanding convertible securities would be adjusted proportionately. After completion, the shares are expected to trade under the new name on a consolidated basis using the existing symbol.
Sirios (SIREF) has begun a 1,800-metre drilling program at its Aquilon gold project in Quebec’s Eeyou Istchee James Bay region.
The program consists of three new holes and extensions of two existing holes. It aims to test the lateral and depth continuity of a gold halo discovered in 2025. Based on geological and structural interpretation, the near-surface halo extends more than 700 metres north to south and spans 300 metres in width. The 2025 drilling produced intervals up to 298.2 metres grading 0.26 g/t gold. Sumitomo Metal Mining Canada funds 51% of the program, while Sirios funds 49% and serves as operator.
Sirios Resources (SIREF) has appointed mining engineer Daniel Deschênes, Eng., MBA, as Vice President, Projects. He will lead execution of the Cheechoo gold project Preliminary Economic Assessment (PEA) and oversee subsequent development stages.
Deschênes brings more than 15 years of experience in open-pit and underground mine development and operations in Québec, Ontario, Africa and South America, including senior roles at Newmont, IAMGOLD, Nemaska Lithium and Windsor Salt. He has deep familiarity with the Eeyou Istchee James Bay region. Sirios will also participate in multiple mining and investor conferences across Europe and Canada in Q3 and Q4 2026 to enhance market visibility and shareholder engagement.
Sirios Resources (OTCQB: SIREF) reported first Phase 1 2026 drill results from its Cheechoo gold project, with 5 holes totaling 1,753 m. Key intercepts include 2.40 g/t Au over 48.5 m (including 77.65 g/t over 1.1 m) and 1.49 g/t over 37.6 m in hole CH26-326, plus 1.16 g/t over 32.2 m and 2.28 g/t over 10.3 m in CH26-327. Visible gold has been observed in 8 holes, including several with assays pending. To date, 33 holes and 13,555 m have been drilled, with four rigs active. According to Sirios, these early results, partly outside the 2025 conceptual pit, support the potential to expand Cheechoo beyond the current 2025 resource estimate, with Phase 1 targeted for completion in September ahead of an updated resource.
Sirios Resources (OTCQB: SIREF) has started Phase 1 of its planned 25,000-metre drilling campaign at the Cheechoo gold project after receiving all required permits, including the ATI. Two drill rigs are on site, with a third expected by late June.
Sirios is deploying a LIBS unit for on-site core analysis, reviewing existing cores, and has completed a helicopter-borne magnetic survey at its Fagnant gold project to guide exploration strategy.
