Greenridge Exploration Inc Initiates Ground Gravity Survey At Carpenter Lake Uranium Project Greenridge Exploration Inc. announced the commencement of a ground geophysical program at its Carpenter Lake Uranium Project, located on the southern margin of the Athabasca Basin in northern Saskatchewan, Canada. Axiom Exploration Group Ltd. of Saskatoon, Saskatchewan, has mobilized a gravity geophysical crew to the Property to survey selected target areas along the Cable Bay Shear Zone, a major structural feature that bisects the Property. Well-known basement-hosted and unconformity-type uranium deposits in the Athabasca Basin region commonly exhibit a gravity low signature – an indicator of potential clay-altered zones associated with uranium mineralization due to hydrothermal alteration reducing the host rock density. Greenridge is carrying out a high-resolution ground gravity survey at the Property during the final weeks of frozen ground conditions to cover target zones A1, A2 and A5, which were identified by previous geophysics and drilling. The helicopter-assisted survey operations will generate a low environmental impact during station measurements, providing a sustainable exploration practice. Carpenter Lake is comprised of twelve mineral claims covering approximately 18,680 hectares that straddle the southern margin of the Athabasca Basin Supergroup sandstones and cover more than fifteen kilometers of the Cable Bay Shear Zone. The Cable Bay Shear Zone is characterized by a well-defined conductive signature, radiometric anomalies, and numerous historically mapped uranium occurrences. The presence of conductive graphitic metasedimentary rocks often associated with uranium deposition in the Athabasca Basin has been confirmed by both historical drilling and the Company’s 2025 drilling on the Property. The 2026 gravity survey will employ a Scintrex CG6 Autograve instrument to collect sub-surface readings within a virtual grid established by a Trimble R12i GNSS global positioning system receiver. Ground penetrating radar will be used to map ice thickness, and to profile lake bottoms for better interpretation of the data collected on frozen lakes. Management cautions that historical results collected and reported by operators unrelated to Greenridge have not been verified nor confirmed by its Qualified Person; however, the historical results create a scientific basis for ongoing work at the Property. Management further cautions that published historical results and discoveries on adjacent or nearby mineral properties are not necessarily indicative of the results that may be achieved on the Property.

Greenridge Exploration Inc. Completes Advanced 3D Inversion and Lithology Modelling Program At Carpenter Lake Uranium Project Greenridge Exploration Inc. completed an integrated 3D multi-physics inversion and machine-learning-assisted lithology modelling program at its Carpenter Lake Uranium Project, located along the Cable Bay Shear Zone on the southern margin of the Athabasca Basin, northern Saskatchewan. The work was completed by Convolutions Geoscience Corp. in collaboration with Computational Geosciences Inc., who served as independent inversion specialists and developers of the Geophysics-Informed Lithology Interpolation platform. The Program represents the first fully integrated reinterpretation of the Project’s historical airborne datasets, including the 2014 versatile time-domain electromagnetic survey, 2015 Falcon Airborne Gravity Gradiometry survey (all seven tensor components), and high-resolution Total Magnetic Intensity data. CGI and Convolutions applied a modern inversion workflow incorporating parametric plate modelling of VTEM conductors, cross-gradient joint inversion of gravity and electromagnetic datasets, 3D lithology model generation using GILI, high-resolution OcTree and tensor meshes, and incorporation of Greenridge’s 2025 drilling data and physical property and structural measurements from drill core. This approach produced 3D physical property models consistent with all available data and a lithology model of the CBSZ corridor, significantly advancing the structural interpretation of the Project. Initial unconstrained VTEM inversions were unable to fully resolve the steep, shear-hosted conductors known from drilling and mapping. CGI applied parametric plate inversions, modelling the CBSZ as a series of steeply dipping rectangular conductive bodies. This method provided a data-driven estimate of strike and dip of graphitic pelite units, conductivity contrasts along the shear zone, and breaks, flexures, and offsets consistent with structural reactivation. These plate geometries were then used as starting models or used in cross gradient inversions, improving the coherence and continuity of the Carpenter Lake conductive system. Falcon AGG data were inverted using both unconstrained and structurally guided approaches. Cross-gradient joint inversion was applied to align density contrasts with the VTEM-derived conductive structures. The Company plans to complete a higher-resolution ground gravity survey across the CBSZ, which will further refine the integrated modeling and future targeting. The resulting gravity model reveals density-low anomalies spatially coincident with conductive shear panels, localized density disruptions adjacent to interpreted structural breaks, and broader corridors of reduced density potentially related to hydrothermal alteration. A secondary inversion was performed using a starting model derived from the GILI lithology output, further improving geological consistency. CGI’s GILI platform integrated TMI magnetic data, surface geological mapping, and drillhole lithology and magnetic susceptibility measurements collected in 2025. GILI leverages proprietary AI and physics-based inversion modeling to create highly accurate 3D lithology models that automatically align geological data with magnetic surveys to pinpoint high-value targets with greater certainty. The resulting 3D lithology model distinguishes graphitic pelite horizons forming the primary conductive targets, low-susceptibility intrusive and quartz-rich units, moderate-susceptibility granitic gneisses, and high-susceptibility banded iron formations contributing to magnetic and gravity anomalies. This model provides a consistent geological framework that ties together conductivity, density, and magnetic susceptibility. The integrated inversion results have materially improved the understanding of structural architecture along the CBSZ. Several high-priority target areas have been identified where steeply dipping conductive plates, coincident density-low signatures, structural breaks and offsets, and favourable lithological architecture converge with a 3D shear corridor: Steeply dipping conductive plates;Coincident density-low signatures;Structural breaks and offsets; and Favourable lithological architecture. Many of these targets remain untested or only partially tested by historical drilling. The Program demonstrates that advanced inversion workflows and machine-learning-assisted lithology modelling can extract significant geological insight from historical airborne and drilling datasets without requiring new geophysical acquisitions. Greenridge believes this modelling approach has significantly enhanced the discovery potential at Carpenter Lake and will directly inform the design and prioritization of the next phase of drilling along the CBSZ. The Company and Convolutions led the geological integration and targeting strategy, while CGI executed the inversion workflow and delivered the 3D physical property and lithology models.

Greenridge Exploration Inc. Announces Commencement of Winter 2026 Drilling Program with Denison Mines At the Hook-Carter Uranium Project in the Athabasca Basin, Saskatchewan Greenridge Exploration Inc. announced that the 2026 winter drilling program is underway at the Hook- Carter Uranium Project located in the southwestern Athabasca Basin region of Saskatchewan, Canada. The Project is owned 20% by Greenridge and 80% by Denison Mines Corp. ("Denison"), with Denison acting as operator of the Project. Hook- Carter is host to the interpreted northeastern strike extensions of parallel structural trends, including the Derkson Trend and the prolific Patterson Lake Corridor ("PLC"), along which multiple uranium deposits and showings have been discovered to the southwest of the Project. Highlights of the Hook- Carter 2026 Drilling Program: Denison and Greenridge plan to drill up to eight diamond drill holes totaling approximately 4,600 metres. Drill targets were defined through the integration of detailed 2025 ground geophysical surveys with historical exploration data that identified key geological indicators of a potential mineralizing system. The 2026 drilling Program has commenced on the Derkson Trend, a northeast-southwest trending conductive corridor east of the PLC that remains underexplored at Hook- Carter. Management further cautions that historical results, discoveries and published resource estimates on adjacent or nearby mineral properties, or other properties located within the Athabasca Basin, whether in reference to stated current resource estimates or historical resource estimates, are not necessarily indicative of the results that may be achieved on the Project. The Gibbons Creek property hosts high-grade uraniferous boulders located in 2013, with grades of up to 4.28% U3O8 3, and the McKenzie Lake project saw a 2023 prospecting program return three samples which included 844 ppm U-total (0.101% U3O8), 273 ppm U-total, and 259 ppm U-total. The Nut Lake property located in the Thelon Basin includes historical drilling which intersected up to 9ft of 0.69% U3O8 including 4.90% U3O8 over 1ft from 8ft depth. In 2024, Greenridge's prospecting program located a float sample that returned 31.13% U3O8, sourced from the Tundra Showing. The Firebird Nickel property has seen two drill programs (7 holes totaling 1,339 m), where hole FN20-002 intersected 23.8 m of 0.36% Ni and 0.09% Cu, including 10.6 m of 0.55% Ni and 0.14% Cu. The Electra Nickel project 2022 drill program included results of 2,040 ppm Ni over 1m and 1,260 ppm Ni over 3.5m. Anuncio • Jan 30

Greenridge Exploration Inc. Announces Results of Summer 2025 Drilling at the Carpenter Lake Uranium Project, Athabasca Basin Area Greenridge Exploration Inc. announced the results of the Summer 2025 diamond drilling program (the ‘Program’) at its Carpenter Lake Project (‘Carpenter Lake’ or the ‘Property’), located on the southern margin of the Athabasca Basin in northern Saskatchewan, Canada. Eight holes were completed for a total of 1,368 metres on selected target areas along the Cable Bay Shear Zone (the ‘CBSZ’), a major structural feature that bisects the Project. Highlights of the 2025 Drilling Program Eight holes were completed for a total of 1,368 m of core NQ drilling across select targets intended to test Geophysical and Geochemical targets along the CBSZ targeting shallow basement-hosted uranium mineralization at the target areas. Two drillholes were lost before reaching their planned depth due to technical issues. Drilling intersected prospective lithologies for hosting uranium mineralization, namely graphitic pelitic gneisses carrying sulphides, with anomalous pathfinder geochemistry including uranium, arsenic, nickel, copper, cobalt, lead and zinc. Intervals of anomalous radioactivity (measured by downhole Mount Sopris 2PGA-1000 downhole gamma probe) were intersected in three of the eight drill holes completed and is associated with structural zones and favorable rock types including graphitic pelite adjacent to favorable cross structures, and structural breaks.Graphitic-sulphidic stacked shear and fault zones were encountered in multiple holes, many featuring prominent brittle reactivation features including breccias, cataclasites, and fault gouge. Anomalous dravite, a pathfinder clay alteration mineral containing boron, which is often found near a potential mineralized system, was observed by short wave infra-red (‘SWIR’) spectroscopy and confirmed by laboratory analysis, showing strongly anomalous Boron associated with structural deformation and anomalous uranium. The 2025 drill program has demonstrated that the prospective graphitic pelitic gneisses at the Project extends further south than previously known, and that anomalous geochemistry observed in the drill core (uranium, boron and base metals) indicate that uranium-bearing fluids have mobilized along the CBSZ. The helicopter-assisted drilling operations generated a low environmental impact during drill moves and drill pad construction, providing a sustainable exploration practice. Following its review of the 2025 drilling results, Greenridge believes that the greatest potential for uranium mineralization within the Project area lies in continued testing of areas where gravity lows coincide with structural breaks, cross cutting structures or offsets in EM conductors. A ground gravity survey is being commissioned consisting of approximately 1,000 survey stations straddling the identified electromagnetic (‘EM’) conductors along the CBSZ trend. Additionally, Greenridge is continuing comprehensive geophysical inversions and lithostructural modelling to gain a more comprehensive understanding of structural elements that may control potential for uranium mineralization. The drilling program successfully confirmed the presence of graphitic pelitic gneisses extending further south than previously known, the combined presence of sulphides and returned anomalous uranium and pathfinder element geochemistry, along with zones of promoted radioactivity associated with favorable structures and rock types. The program also identified stacked graphitic-sulphidic shear zones with evidence of structural reactivation, as well as boron-rich dravite alteration, supporting the interpretation that uranium-bearing fluids have migrated along the shear zone. Work is ongoing at the property with refined geophysical surveys and ongoing targeting work underway.
