Troilus Files Environmental and Social Impact Assessment FOR the Troilus Copper-GOLD Project
TROILUS FILES ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT FOR THE TROILUS COPPER-GOLD
PROJECT
JUNE 25, 2025, Montreal, Quebec – Troilus Gold Corp. (“Troilus” or the “Company”, TSX: TLG ; OTCQX:
CHXMF; FSE: CM5R) is pleased to announce that it has officially filed the Environmental and Social Impact
Assessment (“ESIA”) for its flagship Troilus Copper-Gold Project (“Troilus” or the “Project”) with both the
Government of Québec, via the Ministère de l’Environnement, de la Lutte contre les changements
climatiques, de la Faune et des Parcs (“MELCCFP”), and the Government of Canada, via the Impact
Assessment Agency of Canada (“IAAC”).
The submission of the ESIA marks a major milestone in the development of the Troilus Project,
representing the culmination of over five years of comprehensive baseline studies, robust technical
evaluations, and meaningful engagement with Indigenous and loc al communities. As one of the largest
undeveloped gold and copper projects in North America, this filing is a key step in advancing Troilus along
its path towards construction.
Jacqueline Leroux, Troilus’ Vice President of Environment and Permitting, commented, “The ESIA
submission is a defining moment for Troilus that reflects the unwavering dedication of our internal team
and partners to advance this project in a responsible, transparent, and collaborative manner. This
milestone not only derisks the Project, but also reinforces our long- standing commitment to sustainable
development and positive impact for the communities in which we operate.”
Key highlights of the ESIA include:
Extensive community consultation: The ESIA includes the results of extensive engagement with
the Cree Nation of Mistissini, Oujé -Bougoumou Cree Nation, the Cree Nation Government and
the communities of Chibougamau and Chapais, which helped shape project design and mitigation
strategies.
Historical familiarity with the site: As a past-producing mine (1996–2010), Troilus benefits from
both robust legacy data and a high level of regional understanding of mining operations and their
impacts.
Positive environmental findings: Independent studies conducted by Coalia, the National
Research Council of Canada, Lamont, and the Minesite Drainage Assessment Group ( “MDAG”),
confirm that the Project’s waste rock is non-acid-generating, significantly reducing environmental
risk and long-term water treatment requirements.
The ESIA was developed in collaboration with BluMetric Environmental Inc. , and Stantec, two leading
environmental and engineering firms. Under a rolling submission model, adopted in coordination with the
IAAC and Cree Nation Government, sections of the ESIA were submitted in advance of the final report (see
press release from January 29, 2025) , allowing regulators to begin their assessment early and provide
feedback throughout the drafting process. This is expected to streamline the overall permitting timeline.
With the ESIA filing now complete, the Project formally enters the provincial and federal review process.
In Québec, the submission will be reviewed by COMEX ( “Comité d’examen des répercussions sur
l’environnement et le milieu social” or “Environmental and Social Impact Review Committee”), under the
James Bay and Northern Québec Agreement, while federally, the IAAC will lead a parallel review
supported by public and Indigenous consultations. Final decisions are anticipated by year-end 2026.
Troilus remains committed to transparent engagement and collaborative development, and looks forward
to continuing its work with local and Indigenous partners, as well as government stakeholders, to
responsibly advance one of Canada’s most significant critical mineral projects.
