The management of Sirios Resources Inc. (TSX-V: SOI) is pleased to report assay results from channel samples collected last summer (Figure 1), which included 2.65 g/t Au over 11.0 m (Figure 2). This confirms the extension of gold mineralization beyond the tonalite and into the meta-greywackes outside of the conceptual pit of the 2020 mineral resource estimate of the Cheechoo project. These results highlight a new type of gold mineralization hosted in metasediments, more typical of the Eleonore mine.

In August and September, Sirios carried out mechanized trenching and channel sampling of three areas in the metasediments to the east of the conceptual pit of the Cheechoo gold deposit. A total of 218 samples from 216 meters of channels were sent to the ALS laboratory in Val-d’Or for analysis.

Significant results from these three trenches (2022-A, B and C) are presented below:

A new geological setting for the gold mineralization of the Cheechoo deposit

The high-grade gold results obtained during this program are hosted in metasediments with 2-3% pyrrhotite and arsenopyrite, as well as millimetric quartz-feldspar veinlets (Figure 3), which represents a new geological context for gold mineralization for the Cheechoo deposit.

Intrusive rocks (tonalite and pegmatite) were previously thought to be the only host rocks for gold mineralization at Cheechoo. The discovery of these new high-grade gold zones in the metasediments now confirms the presence of gold mineralization more than 400 meters outside of the tonalite.

Dominique Doucet, President and CEO of Sirios said: “We are delighted with the exceptional results obtained for the first time at surface within the metasediments. This poorly explored geological unit adds major exploration potential to the Cheechoo project, as it represents a new sector favourable for gold mineralization that extends several hundred meters to the east.”

“Our summer campaign proved to be a great success thanks to the results of these new trenches, which seem to be aligned along a northwest-southeast axis, along with the gold-bearing zone intersected in the 2021 drilling, which notably intersected an interval of 0.9 g/t Au over 15.7 m (ref. press release of 12/14/2021). This news is very encouraging and follow-up work (additional trenching and drilling) will therefore be conducted in the metasediments in 2023.”

Assay Quality Control

The channel sampling was carried out, described and sampled by Sirios personnel. Following a strict assay quality assurance and control program, blanks and certified reference materials were incorporated into the sampling sequence. Samples were assayed for gold by fire assay with an atomic absorption finish by ALS laboratories.

About the Cheechoo Property

The Cheechoo gold property is 100% owned by Sirios and consists of 225 claims covering an area of 118 km², divided into three non-contiguous blocks. It is located in Eeyou Istchee James Bay, Quebec, less than 9 km from Newmont’s Eleonore gold mine and is easily accessible by all-season roads. The project’s most recent resource estimate (October 2020) delineated inferred resources of 2.0 million ounces of gold contained in 93.0 million tonnes at 0.65 g/t Au, with significant potential to increase this resource (BBA, P-L. Richard, P. Geo.; J. Torrealba, P. Eng.; D. Evangelista, P. Eng., NI 43-101 Technical Report, Mineral Resource Estimate Update for The Cheechoo Project, 31/10/2020).
