Sirios Announces Its Fully Funded 2026
Exploration Program
A two-phase drilling campaign totaling 35,000 m at the
Cheechoo Gold Project, in addition to work planned at PLEX,
Fagnant, and Aquilon
Montreal, Quebec--(Newsfile Corp. - April 1, 2026) -
Sirios Resources Inc. (TSXV: SOI) (OTCQB:
SIREF)
("Sirios" or the "Company") plans an extensive, fully-funded 2026 exploration program at several
of its gold exploration projects in the Eeyou Istchee James Bay area of Quebec. Details of the proposed
program are provided below.
Cheechoo Gold Project
An initial expansion drilling phase of approximately 25,000 m will begin in the second quarter of 2026,
with the objective of updating the resource estimate. Three sectors are targeted in this first phase,
namely:
1
.
~15,000 m on the modeled exploration target, as presented in the resource estimate (ref.:
press
release dated July 10, 2025
) (see Figure 1)
2
.
~7,500 m in the metasediments at the northeast contact of the main intrusive within the conceptual
pit shell limiting the current mineral resources (see Figure 2)
3
.
~2,500 m in the higher-grade Eclipse sector west of the conceptual resource pit shell (see Figure
2).

"We're looking forward to getting drills turning at Cheechoo in the coming weeks," said Dominique
Doucet, Executive Chairman and Head of Exploration at Sirios. "In addition, a second phase of at least
10,000 m of exploration and follow-up drilling is planned for the first quarter of 2027. The targeting and
timing of this phase will be contingent on the results of the first phase."
"This comprehensive 2026 drill program at Cheechoo will enable us to publish a new resource
estimate," added Jean-Félix Lepage, Sirios' CEO. "We will then use that information to complete a
Preliminary Economic Assessment (PEA) in the first half of 2027."
Aquilon
A work program is planned for the third quarter of 2026 to follow up on the encouraging results obtained
during the 2025 drilling campaign. This program will be developed in April by Sirios and its partner
Sumitomo Metal Mining Canada (Sumitomo). Sirios remains the operator of the Aquilon project, now
shared 49% by Sirios and 51% by Sumitomo. The work program will be announced once it has been
confirmed by the partners.
PLEX
The PLEX project is the subject of compilation work by Sirios' experienced exploration team. A work
plan will be developed before the end of the third quarter of 2026 with the objective of initiating
exploration work in 2027.
The project spans 21,000 hectares along a greenstone belt at the contact of the La Grande and Opinaca
sub-provinces, which constitutes the main gold metallotect for Eeyou Istchee James Bay. PLEX includes
the Orfée zone, which was the subject of a 2003 estimate of 125,000 ounces at 14.5 g/t gold.
[1]
This
estimate is considered a historical estimate, which is not compliant with National Instrument 43-101 and
should not be relied upon as current mineral resources.
Fagnant
The Fagnant project is located approximately 60 km east of Whapmagoostui and Kuujjuarapik, which
are, respectively, Cree and Inuit communities on the border of Eeyou Istchee James Bay and Nunavik.
The exclusive exploration rights (EER) acquired at Fagnant, totaling 98 km², cover more than 80% of the
Archean volcano-sedimentary belt of the Great Whale.
Between 1997 and 2000, about thirty gold or polymetallic (Au, Ag, Pb, Zn, Cu) showings were
discovered by prospecting. In 2018, only a brief inspection of the showings was conducted by the former
holders, validating the 1997-2000 results with selected samples grading up to 44 g/t gold.
[2]
Sirios
considers these results to be historical within the meaning of NI 43-101. There has been no sufficient
work by a qualified person to classify them as current.
A helicopter-borne magnetic survey covering the entire property will be conducted in Q2 2026, and will
be the first significant survey initiated by Sirios since acquiring this project by map designation in 2024.

About the Cheechoo Gold Project
Cheechoo is located approximately 15 km from the Éléonore mine and near infrastructure including,
among others, roads and hydroelectric facilities, in Eeyou Istchee James Bay, Canada. Cheechoo is at
the resource development stage with 35 Mt Indicated resources at 1.12 g/t representing 1,262 koz, and
42.7 Mt of Inferred resources at 1.23 g/t, representing 1,688 koz. In addition, a conceptual exploration
target ranging from 31 to 40 million tonnes of mineralization grading between 1.27 and 1.45 g/t Au has
been estimated. Readers should refer to the mineral resource estimate report,
Technical Report
On
The Cheechoo Project With An Updated Mineral Resource Estimate For The Cheechoo Gold
Deposit, Eeyou Istchee James Bay, Quebec, Canada,
dated July 1, 2025,
by Pierre-Luc Richard of
PLR Resources Inc., an independent and qualified person as defined by National Instrument 43-101. The
complete technical report is available on
SEDAR+
under Sirios' profile, as well as on the Company's
website.
The mineralization at Cheechoo is of the "reduced intrusion-related gold system" type, with the main host
rock being a tonalite intrusion. However, gold can also be found in meta-sedimentary rocks outside the
intrusion, representing additional potential. The 2026 drilling program will verify the potential of the
exploration target.
