Au for 2,416,900 Ounces Inferred, a 48% Increase
Val-d’Or, Quebec, December 18, 2025 – Cartier Resources Inc. (″Cartier″ or the ″ Company″) (TSXV: ECR;
FSE: 6CA) is pleased to announce the results of the Updated Mineral Resource Estimate ("MRE") on its 100%
owned flagship Cadillac Project, located in Val -d’Or (Abitibi, Quebec) . The updated estimates include
approximately 110,000 metres of drilling completed by Cartier from 2016 to 2024 as well as 420,000 metres
drilling completed by previous mining companies. The MRE was independently prepared by PLR Resources Inc.
and Evomine, specialists in mineral resource estimates and project evaluations , in accordance with National
Instrument 43 -101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and is dated December 17,
2025.
Strategic & Investment Significance Highlights of the Updated Mineral Resource Estimate
• Growing gold resource: Compared to the 2023 Preliminary Economic Assessment (″PEA″), total gold
resources now contain s 9,953,000 tonnes at a grade of 2.40g/t Au for 767,800 ounces Measured &
Indicated ("M&I") (a 7% increase) and 35,185,000 tonnes at a grade of 2.14g/t Au for 2,416,900 ounces
Inferred (a 48% increase), following the first-ever consolidation (2022) of all gold sectors across the entire
Cadillac project.
• Increasing confidence & de-risking: M&I resources represent 25% of total resources, including
5,988,000 tonnes at a grade of 2. 61g/t Au for 502,600 ounces Measured , strengthening the project’s
development profile.
• Flexible development pathways: 12% of total gold resources are pit -constrained, offering near -term
optionality with 3,500,000 tonnes at a grade of 1.84g/t Au for 207,800 ounces M&I and 4,740,000 tonnes
at a grade of 1.13g/t Au for 172,600 ounces Inferred.
• Large underground resource & existing infrastructure advantage s: Over 88% of total gold resources
are underground-constrained with 6,450,000 tonnes at a grade of 2.70g/t Au for 559,900 ounces M&I and
30,450,000 tonnes at a grade of 2.29g/t Au for 2,244,200 ounces Inferred. This large resource is supported
by valuable historical infrastructure including a 920 m shaft, 500 m ramp and 7 km of drifts, these could
significantly reduce future capital requirements and allow management to adapt development strategies.
• Camp-scale upside potential: Gold sectors extend over 9 km along the Cadillac and Héva Fault Zones,
covering 66% of a 15 km highly prospective gold corridor, leaving 6 km of strike with strong upside potential
to be fully explored for resource expansion.
• High-quality core sector: The Main Sector (Chimo, East Chimo and West Nordeau deposits) hosts 87%
of total resources within a 3 km mineralized trend and remains open at depth and along strike, providing
strong leverage to further drilling success.
• Significant exploration target: A conceptual exploration target of 8 to 12 Mt of mineralization grading
between 2.2 to 2.8 g/t Au, representing 600,000 to 1,100,000 ounces of gold, highlights the project’s
potential to materially grow beyond the current resource base.
" The updated gold resource, incorporating both pit-constrained and underground scenarios, represents a new
achievement and positions Cartier with a high degree of development flexibility at the Cadillac Project. This
optionality enhances the project’s strategic value and will be further assessed through an updated PEA.
Cadillac stands out as one of the few large -scale Quebec gold projects still delivering rapid resource growth,
situated in a top-tier, pro-mining jurisdiction with established infrastructure and workforce. We look forward to
advancing key value-creation milestones in 2026. " – Philippe Cloutier, President and CEO of Cartier.
" Since acquiring the project in 2016 and consolidating the east –west extensions in 2022, the Cartier team has
systematically de-risked and enhanced the asset’s gold potential through consistent exploration success and
a robust, standardized geological model . The ongoing 100,000 -m drilling program is designed to test the
property at a mining camp scale, support c ontinued resource growth, and deliver meaningful exploration and
blue-sky upside, positioning the project for further value-accretive discoveries. " – Ronan Deroff, Vice President
Exploration of Cartier.
Upcoming Milestones
100,000 m drilling program (Q3 2025 to Q2 2027)
The ambitious 600 -hole drilling program will both expand known gold zones (0 to 300 m deep) and test new
shallow surface high-potential targets. The Company has implemented VRIFY’s AI-Assisted Mineral Discovery
Platform (DORA) to guide exploration priorities and optimiz e drill targeting across the land package. The
objective is to unlock the camp-scale, high-grade gold potential along the 15 km Cadillac and Héva Fault Zones.
Environmental baseline studies & economic evaluation of Chimo mine tailings (Q3 2025 to Q3 2026)
The studies will provide a comprehensive understanding of the current environmental conditions and
implement operations that minimize environmental impact while optimizing the economic potential of the
project. These studies will be supplemented by an initial assessment of the past-producing Chimo mine tailings
to determine whether a quantity of gold can be extracted economically.
Metallurgical sampling and testwork program (Q4 2025 to Q1 2026)
The comprehensive program will characterize the mineralized material, gold recovery potential and validate
optimal grind size defining the most efficient and cost -effective flowsheet. The data generated will directly
support optimized project development a nd have the potential to significantly reduce both capital and
operating costs, while also improving revenue generation and reducing the environmental footprint.
Preliminary economic assessment (2026)
Internal engineering studies have been initiated to validate a multitude of development scenarios that consider
the updated MRE and current market environment. Following the selection of the most optimal scenario, a PEA
will be completed which will also bu ild upon the results of the metallurgical testwork program and the
environmental baseline studies to unveil the updated development strategy and vision of the project.

Notes Accompanying the Mineral Resource Estimate
• Resources are presented as undiluted and in situ for the open -pit scenario within 5m x 5m x 5m blocks
and include internal dilution for the underground scenario and are considered to have reasonable
prospects for economic extraction. The constraining pit s hell was developed using overall pit slopes of
50 degrees. The pit optimization to develop the mineral resource -constraining pit shells was done using
the pseudoflow algorithm in Deswik software. The stope optimization to develop the underground
mineral resource was done using Deswik.SO software.
• The MRE wireframe was prepared using Leapfrog Edge v.2025.1.1 and is based on 4,477 drill holes,
totalling 535,360 meters drilled and 167,978 assays. The cut -off date for the drill hole database was
February 17, 2025.
• Composites of 1.0 metre were created inside the mineralization domains. High-grade capping was done
on the composited assay data. Based on individual statistical study for each zone, composites were
capped between 5.0 g/t Au and 110.0 g/t Au for the high-grade zones, and between 1.0 g/t Au and 5.0 g/t
Au for the low-grade zones.
• Pit constrained Mineral Resources for the base case are reported at a cut -off grade of 0.30 g/t Au; DSO-
constrained Mineral Resources for the base case are reported at a cut-off grade of 1.00 g/t Au and include
internal dilution (must -take). The cut -off grades will be re -evaluated in light of future prevailing market
conditions and costs.
• Specific gravity values were estimated using data available in the drill hole database. Density values
between 2.80 and 2.88 were applied to the model for hard rock and 2.00 for overburden.
• Grade model resource estimation was calculated from drill hole data using an Ordinary Kriging
interpolation method in a sub -blocked model using blocks measuring 5 m x 5 m x 5 m in size and sub -
blocks down to 0.625m x 0.625m x 0.625m. Ordinary kriging (OK), inverse square distance (ID2), Nearest
neighbour (NN) interpolation methods were tested, resulting in no material difference in the Mineral
Resource Estimates.
• The Measured, Indicated and Inferred Mineral Resource categories are constrained to areas where drill
spacing is less than 12.5m, 25m and 100 metres respectively and show reasonable geological and grade
continuity. An additional requirement for the Measure d category is the close proximity of underground
infrastructure. Cookie cutters were used to define categories based on the above parameters. Based on
historical mining and geological knowledge of the deposit, drill spacing was increased up to 140m in the
shoot direction to define inferred resources for some zones.
Conceptual Exploration Target
A significant Exploration Target was identified during the preparation of the MRE. This conceptual Exploration
Target is integrated into the model used for the MRE, with the aim of facilitating future targeting and drill hole
planning.
Highlights of the Exploration Target
• Estimated total of 8 to 12 million tonnes of mineralization grading between 2.2 to 2.8 g/t Au, representing
600,000 to 1,100,000 million ounces of gold.
Disclosure warnings in respect to an exploration target review
• An exploration target is not a National Instrument 43 -101 compliant resource or reserve.
• The Exploration Target is confirmed only as a target for further exploration.
• Potential quantity and grades are conceptual in nature only.
• There has not been sufficient drilling to define any mineral resource on this Exploration Target; drilling
intercepts crosscut the Exploration Target but drill spacing is too scarce to classify these blocks as
Inferred Mineral Resources.
• There is no certainty that further drilling will result in the target being delineated as a mineral resource.
• The assessment of the target for further exploration was completed by PLR Resources, a consultant
independent of the company. The estimation of the potential quantity and grade of the exploration target
was based on the same drill hole database used for th e Mineral Resource Estimate. With the available
drilling information, PLR developed conceptual mineralized zones. Core samples were composited, and
the composited gold assays were capped (similarly to the Mineral Resource Estimate). The gold values
were interpolated into a three -dimensional block model using Ordinary Kriging. To estimate a tonnage,
PLR used the same specific gravity values used for the Mineral Resource Estimate .
• Underground DSO stopes were run to constrain the Exploration Target.

Cautionary Statement Regarding Mineral Resources
The mineral resources disclosed in this press release conform to NI 43-101 standards and guidelines and were
prepared by independent qualified persons. The above-mentioned mineral resources are not mineral reserves
as they do not have demonstrated economic viability. The quantity and grade of the reported Inferred Mineral
Resources are conceptual in nature and are estimated based on limited geological evidence and sampling.
Geological evidence is sufficient to imply but not verify geological grade and/or quality of continuity. An Inferred
Mineral Resource has a lower level of confidence relative to a Measured or Indicated Mineral Resource and
constitutes an insufficient level of confidence to allow conversion to a Mineral Reserve. It is reasonably
expected, but not guaranteed, that the majority of Inferred Mineral Resources could be upgraded to Measured
or Indicated Mineral Resources with additional drilling. The National Instrument 43 -101 Technical Report,
including the mineral resources contained in this ne ws release, will be delivered and filed on SEDAR within 45
days of the date of this news release.
