Sirios Begins Drilling at the Aquilon Gold Project in Eeyou Istchee James Bay, Quebec

Sirios begins 1,800-metre drilling at Aquilon to test a large gold halo in Quebec.

What the company is saying

Sirios Resources Inc. announces the start of a 1,800-metre diamond drilling program at the Aquilon gold project in Eeyou Istchee James Bay, Quebec, with three new holes and two extensions using a helicopter-supported rig. The company frames this as a step to confirm the lateral and depth continuity of a gold halo discovered in 2025, which extends over 700 metres laterally and 300 metres in width, dipping eastward. CEO Jean-Félix Lepage highlights Aquilon’s history of high-grade intercepts, citing 12,906.5 g/t Au over 0.2 m in the Lingo zone, and positions the program as a way to better define the size of the gold halo. The announcement emphasizes the project's joint venture structure—51% Sumitomo Metal Mining Canada, 49% Sirios—with Sirios as operator. The tone is confident, focusing on the project's high-grade past results and the scale of the current exploration. The company references ongoing summer exploration at Cheechoo but centers this update on Aquilon’s immediate drilling activity.

What the data suggests

The program involves 1,800 metres of diamond drilling, targeting a gold halo interpreted to extend over 700 metres laterally and 300 metres in width. The 2025 drilling program achieved intervals up to 298.2 metres grading 0.26 g/t Au. Historical intercepts at Aquilon include 12,906.5 g/t Au over 0.2 m (Lingo), 3,527.4 g/t Au over 0.4 m (Moman), and 133.67 g/t Au over 0.8 m (Fleur-de-Lys). The project is a joint venture with 51% funding from Sumitomo and 49% from Sirios, covering 68 km² with 140 Exclusive Exploration Rights and 32 gold showings discovered to date. The current drilling is positioned less than 2 km from the Lingo zone and 3 km from Moman, targeting the near-surface halo. No new assay results are reported in this release; the focus is on operational commencement and geological context. The evidence supports that drilling is underway and that the project has a history of high-grade but narrow intercepts, with the broader gold halo’s economic significance yet to be demonstrated.

Analysis

The announcement is generally proportionate in tone, focusing on the commencement of a new 1,800-metre drilling program at the Aquilon gold project. Most claims are factual and supported by operational data, such as the number of holes, project ownership, and historical high-grade intercepts. The only forward-looking statements relate to the objective of confirming and better defining the gold halo discovered in 2025, which is a standard exploration-stage goal. There is some narrative inflation in referencing Aquilon as having 'some of the highest-grade drill intercepts ever obtained in Quebec' without benchmarking, and in highlighting the potential of the gold halo before results are available. However, the majority of the release is factual, and the capital outlay is not described as large or transformative—just routine exploration. No immediate financial impact or profitability data is disclosed, but this is normal for an exploration-stage update. The gap between narrative and evidence is modest, with most statements grounded in disclosed technical facts.

Risk flags

• ●The economic significance of the gold halo remains unproven, as no resource estimate or economic assessment is disclosed; the 0.26 g/t Au over 298.2 metres is low-grade, and the high-grade intercepts are very narrow, raising questions about scalability.
• ●The project’s value is contingent on successful drilling outcomes; if the new program fails to confirm continuity or grade, the exploration thesis could weaken, and investor interest may decline.
• ●Operational risks include the technical challenges of helicopter-supported drilling in a remote area, which can increase costs and complicate logistics, potentially leading to delays or budget overruns.
• ●The joint venture structure (51% Sumitomo, 49% Sirios) means Sirios is not the majority owner, so future development decisions may depend on Sumitomo’s priorities and continued funding.

Bottom line

Sirios Resources has commenced a 1,800-metre drill program at Aquilon, targeting a large, low-grade gold halo near zones with some of Quebec’s highest historical gold intercepts. The project is well-funded through a joint venture with Sumitomo, and the operational groundwork is in place. While historical grades are exceptional, they are confined to very narrow intervals, and the broader halo’s economic potential is still untested. Investors should focus on the upcoming drill results to gauge whether the halo contains continuous, mineable-grade mineralization. The most important takeaway is that this program is a technical test of scale and continuity; without strong new assays, the project’s value proposition remains speculative.

Announcement summary

(TSXV:SOI) (OTCQB:SIREF) (FSE:377A) Sirios Resources Inc. has commenced a 1,800-metre diamond drilling program at the Aquilon gold project in Eeyou Istchee James Bay, Quebec. The program includes three new drill holes and the extension of two existing holes, utilizing a helicopter-supported drill rig. The main objective is to confirm the lateral and depth continuity and the extent of a large gold halo discovered during the 2025 drilling program. This near-surface gold halo extends laterally for more than 700 metres from south to north, with a width of 300 metres and an eastward dip, based on geological and structural interpretation. In 2025, drill hole intervals up to 298.2 metres grading 0.26 g/t Au were achieved, as published in the February 10, 2026 press release. The new discovery is located less than 2 km southwest of the high-grade Lingo zone and 3 km from the Moman zone. Jean-Félix Lepage, CEO of Sirios, stated that Aquilon has produced some of the highest-grade drill intercepts ever obtained in Quebec, including 12,906.5 g/t Au over 0.2 m in the Lingo zone. The current drilling program aims to better determine the size of the gold halo discovered last year. The Aquilon project is a joint venture between Sumitomo Metal Mining Canada (51%) and Sirios (49%), with Sirios acting as operator. The project consists of 140 Exclusive Exploration Rights (EER) covering an area of 68 km², located 10 km south of the Laforge-1 hydroelectric power station and accessible by all-season roads. To date, 32 gold showings have been discovered on the project. Notable drill intercepts include 12,906.5 g/t Au over 0.2 m (Lingo showing), 3,527.4 g/t Au over 0.4 m (Moman showing), and 133.67 g/t Au over 0.8 m (Fleur-de-Lys showing), as referenced in press releases from June 26, 2008 and January 19, 2011. Roger Moar, P.Geo., a Qualified Person under National Instrument 43-101 and an employee of Sirios, has reviewed and approved the scientific and technical information in this press release. Sirios Resources is focused on developing its Cheechoo gold deposit and advancing other gold projects in the Eeyou Istchee James Bay region of Quebec, Canada.
