   VAL-D’OR, Quebec, Sept.  09, 2025  (GLOBE NEWSWIRE) -- Cartier Resources Inc. (? Cartier ? or the ? Company ?)  (TSXV: ECR; FSE: 6CA) is pleased to announce it has awarded the  contract for beginning the first environmental baseline studies for the  Cadillac project and an initial evaluation of economic assessment of the  past-producing Chimo mine tailings to Stantec, a global leader in  sustainable design and engineering. The baseline studies will be divided  into two distinct parts which include 1) environmental baseline desktop  study and 2) preliminary environmental geochemical characterization.
        " These  initial baseline studies will form a foundation for Cartier by  providing a comprehensive understanding of the current environmental  conditions and identifying potential impacts of future development  planning of the Cadillac project. The results will help guide our  advancing strategies in a responsible and sustainable manner, enabling  the design and implementing operations that minimize environmental  impact while optimizing the economic potential of the project. " – Philippe Cloutier, President and CEO of Cartier.
        " We  continue to advance the Cadillac project with a dual-focus strategy:  drilling an ambitious 100,000-meter drilling campaign that combines the  extensions of known gold zones and the exploration of new high-priority  targets, identified using cutting-edge AI technology through our  collaboration with VRIFY and now launching of the foundational  environmental baseline studies. These efforts will be conducted  simultaneously, with the potential for additional work emerging as the  project advances. " – Ronan Deroff, Vice President Exploration of Cartier.
        Below is the description of the different parts:
        Part 1 – Environmental Baseline Desktop Study
        The  environmental desktop study aims to document and characterize the  potential environmental constraints on the Cadillac project footprint.  This approach identifies potential environmental issues, such as  atmospheric conditions, surface and groundwater management, wetlands and  natural environments, terrestrial, avian and aquatic fauna as well as  land uses.
        The approach consists of a  rigorous document review that will allow for planning the future general  development of the Cadillac project, identifying sensitive areas and  minimizing environmental impacts. This first step will permit to plan a  comprehensive field work as a next step to the environmental baseline  studies. All the information will be sufficiently comprehensive to serve  as a basis for drafting Chapter 20 of a possible update to the  Preliminary Economic Assessment (PEA).
        Part 2 – Preliminary Environmental Geochemical Characterization
        The  preliminary environmental geochemical characterization study aims to  assess the potential geochemical risks of the waste rock and ore that  will be extracted from the operations, as well as the tailings generated  during ore processing.
        In accordance with the criteria of the Guide de caractérisation des résidus miniers et du minerai  (GCRMM), geochemical characterization is used to classify mining  materials in terms of their acid generation and metal leaching  potential. Static tests will be conducted on approximately fifty samples  representative of the various lithologies present on the site to  determine appropriate management methods for these materials, in  accordance with the guidelines of Directive 019 of the Ministère de  l’Environnement, de la Lutte contre les changements climatiques, de la  Faune et des Parcs (MELCCFP).
        Part 3 – Assessment of the economic assessment of the past-producing Chimo mine tailings
        This  assessment aims to determine whether economic recovery of the Chimo  mine tailings is feasible, considering its geochemical, granulometric  and metallurgical characteristics.
        The study  will consist of systematic sampling, with approximately fifty sample  sites planned to cover the entire tailings facility. All required  authorizations to perform the sampling will be obtained prior to the  field work.

        About Cadillac Project
        The  Cadillac Project, covering 14,000 hectares along a 15-kilometre stretch  of the Cadillac Fault, is one of the largest consolidated land packages  in the Val-d’Or mining camp. Cartier’s flagship asset integrates the  historic Chimo Mine and East Cadillac projects, creating a dominant  position in a world class gold mining district.
        With  excellent road access, year-round infrastructure and nearby milling  capacity, the project is ideally positioned for rapid advancement and  value creation.
        Using a gold price of  US$1,750/oz, a Preliminary Economic Assessment demonstrated the economic  viability of a 2-km segment, compared to the 15 km that will be the  subject of the 100,000 m drilling program, with an average annual gold  production of 116,900 oz over a 9.7-year mine life. Indicated resources  are estimated at 720,000 ounces (7.1 million tonnes at 3.1 g/t Au) and inferred resources at 1,633,000 ounces (18.5  million tonnes at 2.8 g/t Au).
