Cartier Resources Inc. (″ Cartier ″ or the ″ Company ″) (TSXV: ECR,OTC:ECRFF; FSE: 6CA) is pleased to announce the fourth batch of results from the fully funded 100,000-m drilling program (2 drill rigs) for the Contact Sector and more precisely, the North Contact Zone (NCZ), on its 100%-owned Cadillac Project, located in Val-d’Or (Abitibi, Quebec). The NCZ consists of three parallel high-grade gold zones: NCZ1, NCZ2 and NCZ3, spaced approximately 50 m apart.

Strategic Highlights from Contact Sector

Drill Hole Results of NCZ (Figures 1 & 2)

• CA25-536 intersected 339.6 g/t Au over 0.5 m included in 111.5 g/t Au over 2.0 m (NCZ1).
• CA25-532 graded 22.0 g/t Au over 1.0 m included in 11.4 g/t Au over 2.0 m (NCZ1).
• CA25-535 reported 17.1 g/t Au over 1.0 m included in 9.6 g/t Au over 2.0 m (NCZ1).
• CA25-531 intersected 7.0 g/t Au over 3.0 m included in 3.2 g/t Au over 12.5 m (NCZ3).
• CA25-533 graded 11.0 g/t Au over 0.7 m included in 3.9 g/t Au over 4.7 m (NCZ3).

Significance for Investors

• Recent drilling results continue to clearly demonstrate the presence of a shallow and extensive mineralized system (400 m in strike length by 300 m in depth), hosting multiple stacked high-grade gold zones with significant grades , widths and continuity .
• Holes CA25-531 and CA25-536 represent the deepest holes completed by Cartier and confirm the gold system remains robust and open in all directions , suggesting significant expansion potential .
• All the drilling objectives were successfully achieved, namely, enhance understanding of the mineralization style associated with the newly identified Héva Fault Zone and define a gold enrichment vector to guide future drilling campaigns.
• The combination of exposed bedrock , minimal overburden (5 m) and proximity to year-round road access (250 m) positions NCZ as a highly strategic asset for potential shallow operation scenarios .

Next Steps

• Upcoming drilling is required on NCZ to extend gold mineralization closer to surface (0-150 m) to support a future gold inventory for this new highly strategic sector.
• Further exploration drilling is already planned to test several new high-priority regional targets at Contact Sector, backed by detailed structural and geological modelling and VRIFY’s artificial intelligence (AI) driven targeting , reinforcing the potential for additional gold discoveries .

‘ Encouraged by these results, Cartier is now evaluating an expansion of its drilling program toward the eastern extensions of NCZ, where multiple geophysical anomalies identified, outlining a highly prospective 5 km-long target zone with strong potential for new gold discoveries. ‘ – Philippe Cloutier, President and CEO of Cartier.

‘ Cartier has now released its third round of results from NCZ, each time delivering outcomes that have exceeded the company’s expectations. These consistent successes highlight the robustness and continuity of this high-grade gold system, reinforcing the strategic importance of focusing exploration efforts in this sector . ‘ – Ronan Deroff, Vice President Exploration of Cartier.

* Occurrences of visible gold (VG) have been noted in the drill core at various intervals. ** Based on the observed intercept angles within the drill core, true thicknesses are estimated to represent approximately 55-70 % of the reported core length intervals.

Contact Sector

The Contact Sector is a highly prospective area featuring the North Contact Zone (‘ NCZ ‘) and several newly defined high-priority drill targets.

The NCZ lies along an east-west trending, strongly sheared corridor (Héva Fault Zone), situated approximately 900 m north of the Cadillac Fault Zone, and occurs at the contact between the hanging wall mafic to intermediate volcanics (basalt to andesite) of Louvicourt Group and the footwall turbiditic sedimentary rocks (wacke-mudrock) of Cadillac Group. This lithological contact is a favorable horizon for hydrothermal fluid flow, likely related to synvolcanic gold deposition.

The NCZ, defined by at least three parallel gold-rich zones, are typically and primarily associated with a fine-grained and disseminated arsenopyrite-pyrrhotite mineralization, with a pervasive biotite-chlorite-carbonate alteration, all crosscut by late-stage smoky quartz vein and veinlet stockworks containing visible gold. Locally, accessory minerals such as sphalerite, galena and tourmaline are observed.

Milestones of 2025-2027 Exploration Program

100,000 m Drilling Program (Q3 2025 to Q2 2027)

The ambitious 600-hole drilling program will both expand known gold zones and test new shallow surface high-potential targets. The objective is to unlock the camp-scale, high-grade gold potential along the 15 km Cadillac Fault Zone. It is important to note that Cartier’s recent consolidation of this large land holding offers the unique opportunity in over 90 years for unrestricted exploration.

Environmental Baseline Studies & Economic Evaluation of Chimo mine tailings (Q3 2025 to Q3 2026)

The baseline studies will be divided into two distinct parts which include 1) environmental baseline desktop study and 2) preliminary environmental geochemical characterization. The initial baseline 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 economic potential 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 metallurgical testwork program includes defining of expected gold recovery rates and improving historical results from the Chimo deposit, as well as establishing metallurgical recovery data for the first-time for the East Chimo and West Nordeau satellite deposits, where no previous data exists. This 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 and have the potential to significantly reduce both capital and operating costs, while also improving the environmental footprint.

Quality Assurance and Quality Control (QA/QC) Program

The drill core from the Cadillac Project is NQ-size and, upon receipt from the drill rig, is described and sampled by Cartier geologists. Core is sawn in half, with one half labelled, bagged and submitted for analysis and the other half retained and stored at Cartier’s coreshack facilities located in Val-d’Or, Quebec, for future reference and verification. As part of Quality Assurance and Quality Control (QA/QC) program, Cartier inserts blank samples and certified reference materials (standards) at regular intervals into the sample stream prior to shipment to monitor laboratory performance and analytical accuracy.

Drill core samples are sent to MSALABS’s analytical laboratory located in Val-d’Or, Quebec, for preparation and gold analysis. The entire sample is dried and crushed (70% passing a 2-millimeter sieve). The analysis for gold is performed on an approximately 500 g aliquot using Chrysos Photon Assay technology, which uses high-energy X-ray excitation with gamma detection to quickly and non-destructively measure gold content.

Alternatively, samples are submitted to Activation Laboratories Ltd. (‘Actlabs’), located in either Val-d’Or or Ste-Germaine-Boulé, both in Quebec, for preparation and gold analysis. The entire sample is dried, crushed (90% passing a 2-millimetre sieve) and 250 g is pulverized (90% passing a 0.07-millimetre sieve). The analysis for gold is conducted using a 50 g fire assay fusion with atomic absorption spectroscopy (AAS) finish, with a detection limit up to 10,000 ppb. Samples exceeding this threshold are reanalyzed by fire assay with a gravimetric finish to determine high-grade values accurately.

Both MSALABS and Actlabs are ISO/IEC 17025 accredited for gold assays and implement industry-standard QA/QC protocols. Their internal quality control programs include the use of blanks, duplicates, and certified reference materials at set intervals, with established acceptance criteria to ensure data integrity and analytical precision.

Toronto, Ontario November 4, 2025 TheNewswire – Laurion Mineral Exploration Inc. (TSX.V: LME | OTC: LMEFF) (‘LAURION’ or the ‘Corporation’) is pleased to announce encouraging results from its 7,700-metre Summer 2025 drill exploration program at the 100%-owned Ishkõday Project, located 220 km northeast of Thunder Bay in Greenstone, Ontario. The first five drill results were announced in the Corporation’s press releases dated August 19, 2025 and September 23, 2025, respectively, which targeted the high-grade gold-bearing vein systems of the Sturgeon River Mine area. Reference is also made to the Corporation’s press releases dated September 5, 2025, May 27, 2025 and May 8, 2025.

The reported drill holes below, LME25-061 and LME25-062, totalling 954 m were designed to evaluate the mineralized system at the historic Brenbar Mine area, stepping out to the north and northeast of the of the historic mine shaft.

Highlights of Drill Holes LME25-061 and LME25-062

LME25-061

• 2.70 m @ 0.22 g/t Au from 152.6 m to 155.3 m

• 2.50 m @ 0.20 g/t Au from 167.5 m to 170 m

• 2.25 m @ 0.88 g/t Au from 213.85 m to 216.10 m, including 1.70 m @ 1.10 g/t Au from 214.4 m

LME25-062

• 3.00 m @ 0.49 g/t Au from 304.0 m to 307 m, including 1.0 m @ 1.34 g/t Au from 304.0 m

• 2.00 m @ 0.50 g/t Au from 111.0 m to 113.0 m, including 0.5 m @ 1.45 g/t Au from 111.80 m

• 1.20 m @ 0.76 g/t Au from 105.7 m to 106.9 m, including 0.7 m @ 1.07 g/t Au from 105.7 m

• 1.05 m @ 2.68 g/t Au from 117.6 m to 118.65 m, including 0.5 m @ 5.18 g/t Au from 118.15 m

• 1.15 m @ 0.39 g/t Au from 310.7 m to 311.85 m

• 1.10 m @ 1.63 g/t Au from 454.4 m to 455.5 m

These new intercepts not only confirm the continuity of gold-bearing structures near the Brenbar Shaft, but also demonstrate how far our understanding of Ishk õ day has advanced since the early 2010 drilling campaigns,’ said Cynthia Le Sueur-Aquin, President and CEO of Laurion Mineral Exploration Inc. ‘Our 2025 drill core is fully oriented, allowing precise structural interpretation and integration into our evolving 3D geological model — a critical step toward defining the geometry and scale of the mineralized system.’

The 2025 drill program targeted a cluster of complex folded gold-bearing vein structures in the Brenbar Shaft namely No 1, 2, 2A and No. 7 vein sets confirmed in historic drilling by Prodigy Gold Inc. ( Jamie Solomon & Jerry Light, June 13, 2011 ). That work returned multiple higher-grade intercepts, including 3.77 g/t Au over 1.30 m and 1.33 g/t Au over 1.0 m in BB09-03 , 5.50 g/t over 2.5 m, 1.39 g/t Au over 1.0 m and 1.47 g/t Au over 1.0 min BB09-04 , 2.29 g/t Au over 1.10 m and 0.39 g/t Au over 15.90 m in BB09-09 , 0.549 g/t Au over 12.50 m in BB09-10 , and 1.56 g/t Au over 1.0 m, 0.51 g/t Au over 6.30 m, 3.26 g/t Au over 0.80 m and 0.66 g/t Au over 8.20 min BB10-27 which tested No. 15 Vein, #25 trench vein . The results confirm high-grade quartz-vein hosted gold within sheared volcanic rocks. They provide the basis for LAURION’s 2025 program to test continuity and strike length at Brenbar, and to collect oriented core for detailed structural analysis and 3D modeling.

Note: (Intervals represent core length; true widths are estimated at ~70–90% of reported intervals.)

Sampling and QA/QC Protocols

All drill core is transported and stored inside the core facility located at the Ishkõday Project in Greenstone, Ontario. LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a ‘rice’ white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (InductivelyCoupledPlasma – AtomicElement-Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.

A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QAQC were verified, and no contamination or bias have been observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Beardmore and moved to the core storage facility at the Ishkõday Project.

That work returned multiple higher-grade intercepts, including 3.77 g/t Au over 1.30 m and 1.33 g/t Au over 1.0 m in BB09-03 , 5.50 g/t over 2.5 m, 1.39 g/t Au over 1.0 m and 1.47 g/t Au over 1.0 min BB09-04 , 2.29 g/t Au over 1.10 m and 0.39 g/t Au over 15.90 m in BB09-09 , 0.549 g/t Au over 12.50 m in BB09-10 , and 1.56 g/t Au over 1.0 m, 0.51 g/t Au over 6.30 m, 3.26 g/t Au over 0.80 m and 0.66 g/t Au over 8.20 min BB10-27 which tested No. 15 Vein, #25 trench vein . The results confirm high-grade quartz-vein hosted gold within sheared volcanic rocks. They provide the basis for LAURION’s 2025 program to test continuity and strike length at Brenbar, and to collect oriented core for detailed structural analysis and 3D modeling.

Sampling and QA/QC Protocols

All drill core is transported and stored inside the core facility located at the Ishkõday Project in Greenstone, Ontario. LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a ‘rice’ white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (InductivelyCoupledPlasma – AtomicElement-Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.

A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QAQC were verified, and no contamination or bias have been observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Beardmore and moved to the core storage facility at the Ishkõday Project.
