Press Release

April 1, 2026

Highlights

• ESIA Submission: PMET Resources (“PMET” or the “Company”) has submitted its Environmental and Social Impact Assessment (ESIA) for the Shaakichiuwaanaan CV5 Lithium Project, marking the most significant milestone in the Project’s permitting journey to date. The project is subject to both a provincial and federal impact assessment, both of which have been submitted for review by respective authorities.
• Technical Foundation: The ESIA, together with the Feasibility Study released in October 2025, provides the comprehensive data required for government review of the Shaakichiuwaanaan Lithium Project. The ESIA submission marks the culmination of over four years of rigorous baseline data collection, technical evaluations, and extensive engagement with the Cree communities, local stakeholders, and government partners across all regulatory levels.
• The ESIA encompasses a comprehensive multidisciplinary analysis covering:
  • Environmental Baseline Studies:  air quality, water resources, terrestrial and aquatic ecosystems, soil and geology.
  • Indigenous consultation and engagement: extensive dialogue with the Cree Nation, cultural heritage and traditional land use.
  • Socio and economic assessment: impacts on employment, community infrastructure and supply chain benefits.
  • Cumulative Effects assessment:  assessment of combined impacts with other projects in the region.
  • Climate and Greenhouse Gas Considerations: The climate resilience and accounting of total greenhouse gas emissions from the project is included.
  • Impact mitigation and management: detailed strategies to minimize environmental and social effects

Grace Barrasso, PMET EVP of ESG and Corporate Affairs, commented: “The submission of this ESIA represents the culmination of years of rigorous scientific field work and meaningful dialogue with our Cree partners. Our goal is to develop Shaakichiuwaanaan as a model for sustainable critical mineral extraction in North America, ensuring that the environmental and social values of the Eeyou Istchee are protected while contributing to the global energy transition.”

Ken Brinsden, PMET CEO and President, stated: “Moving from discovery to a formal ESIA submission and a completed Feasibility Study in roughly four years is a testament to the quality and scale of Shaakichiuwaanaan and the dedication of our team. Congratulations to our team and external advisors for their contributions to our premier project, creating a strong platform for our continuing engagement with the Cree and regulators as our project continues down the development pipeline.”
