(CSE: VRTX) (OTC: VTECF) (FSE: AA3) (“Vortex” or the “Company”)\nis pleased to announce, further to its news release dated July 16, 2026, that\nit has received the final technical study prepared by Lonquist Field Service\n(Canada), ULC (“Lonquist”) for the Company’s Robinsons River Salt\nProject (the “Project”), located approximately 35 kilometres south of\nStephenville, Newfoundland and Labrador. The study integrates available\ngeological, seismic, gravity and drilling information to refine the\ninterpretation of the Project’s subsurface salt structures, assess available\ninformation regarding salt quality, identify potential future drilling targets\nand recommend a staged program of further technical work. The Company notes\nthat the study was not prepared pursuant to NI 43-101, nor by a Qualified\nPerson (as such term is defined in NI 43-101).\n\nHighlights\n* Seismic, gravity and drilling data support the presence of a substantial\nwestern salt structure, with the 2024 drill hole VTX-24-W-02 intersecting an\ninterval of approximately 278 m gross salt.\n* Seismic interpretation identifies a potential incremental step-out west of\nVTX-24-W-02 where the salt section may reach approximately 350 metres in\nthickness.\n* Reprocessed gravity data indicate a large, untested eastern target that may\nbe deeper and potentially contain cleaner salt than the currently drilled\nwestern structure; this interpretation is based on gravity data and remains\nunconfirmed by drilling.\n* Next steps include detailed core analysis, source-water and disposal studies\nand technical planning.\nThe study confirms that Robinsons River hosts a thick halite-bearing system\nand identifies additional exploration potential, particularly within the\nuntested eastern block. It also establishes a clearer framework for evaluating\nsalt quality, subsurface geometry, drilling risk and potential commercial\napplications. Additional technical work will be required before the Company\ncan determine whether the Project is suitable for commercial salt production,\nbrine production or underground energy storage. No mineral resource or\nreserve, commercial production rate, storage-cavern design, storage capacity\nor economic evaluation has been established for the Project.\n\nGeological and Geophysical Interpretation\n\nFigure 1 presents the final gravity-inversion salt-thickness model, and Figure\n2 presents the spatial differences between the seismic-derived and\ngravity-inversion interpretations. The latest Robinsons River interpretation\nincorporates legacy seismic surveys, airborne and surface gravity data,\nhistorical well information and the results of the Company’s recent drilling\nprogram. The study concluded that the western salt block is supported by the\nstrongest combination of seismic, gravity and drilling control, with\nVTX-24-W-02 confirming the presence of a substantial halite-bearing interval\nwithin the interpreted structure.\n\nThe study found that VTX-24-W-02 intersected an approximately 278-metre gross\nsalt interval. The term “gross salt interval” includes the broader\nhalite-bearing interval and should not be interpreted as 278 metres of\ncontinuous, high-purity halite. Legacy seismic data are considered sufficient\nto map the interpreted minimum extent of the western structure and indicate\nthat the salt section may thicken locally toward a potential step-out target\nwest of VTX-24-W-02. This proposed “Cloverleaf” location would represent\nan incremental step-out from the existing well and has an interpreted salt\nthickness of approximately 350 metres.\n\nAs part of the study, previously acquired airborne gravity data were\nreprocessed after it was determined that the original processing had used an\ninappropriate terrain-correction. Revised terrain corrections were\nincorporated into an updated gravity inversion, providing an appropriate basis\nfor comparing the gravity response with the seismic interpretation. Based on\nthe seismic interpretation, the final gravity inversion used fixed assumptions\nfor the geometry of the Ship Cove Limestone structure and an assumed salt\ndensity of 2.30 grams per cubic centimetre. Under those assumptions, the model\nindicates additional potential salt east of VTX-24-W-02 and comparatively less\nsalt immediately west of the drill hole than represented by the seismic salt\nisochore model. The seismic and gravity datasets therefore provide related but\nnot identical interpretations. Seismic data support the Cloverleaf step-out\nwest of VTX-24-W-02, while the gravity-difference model indicates that the\nmost substantial additional salt volume may occur farther east. These\ndifferences reflect the indirect nature of both datasets and will require\nadditional density information and drilling control to resolve.\n\nThe updated interpretation also identifies a western gravity anomaly beyond\nthe currently defined salt structure and a larger eastern exploration target.\nThe western anomaly is supported by gravity but occurs in an area where the\navailable seismic data are considered marginal in quality. The eastern target\noccurs where a broad gravity low broadly coincides with seismic features\ninterpreted as possible salt. The seismic support for this target is\nconsidered to be ambiguous. The prospective top of the eastern salt structure\nmay occur approximately 1,100 to 1,300 metres below surface, and remains\nuntested by drilling.\n\nThe western block is considered to be shallower, closer to existing\ninfrastructure and supported by a higher level of geological confidence. The\neastern block is farther from infrastructure and deeper, but the gravity\nresponse may indicate a greater proportion of lower-density material and\ntherefore potentially cleaner salt. This remains an exploration hypothesis and\nhas not been confirmed through drilling, core analysis or open-hole density\nlogging.\n\n\n\nFigure 1. Final gravity-inversion salt-thickness model for the Robinsons River\nSalt Project, showing the drill-tested western block and the untested western\nand eastern gravity anomalies. Contours represent modelled gross salt-interval\nthickness in metres. The inversion assumes a fixed geometry for the Ship Cove\nLimestone structure and a salt density of 2.30 grams per cubic centimetre. The\nmapped thicknesses are interpretive, have not been verified throughout by\ndrilling and do not constitute a mineral resource or mineral reserve estimate.\n\n\n\nFigure 2. Difference between seismic-derived and gravity-inversion\nsalt-thickness models, calculated as seismic-derived thickness minus\ngravity-inversion thickness. Negative values indicate areas where the gravity\ninversion models a thicker salt interval than the seismic interpretation,\nwhile positive values indicate the reverse. Values are expressed in metres and\nrepresent model-to-model differences, not measured salt thickness.\n\nSalt Quality\n\nThe study reviewed the available descriptions of the VTX-24-W-02 core to\nprovide a preliminary assessment of salt quality. The study describes the\ninterval from 327.0 to 516.5 metres as a heterogeneous halite-bearing interval\ndominated by dark grey to black halite, with frequent mudstone interbeds,\nmuddy salt, mud skins, fractures and minor cleaner translucent salt veins.\nSeveral comparatively thick intervals were described as higher-quality salt;\nhowever, mud-rich salt and salt-cemented mudstone intervals may materially\nreduce the overall salt percentage and influence the suitability of the\ndeposit for potential commercial applications.\n\nBased solely on the available core descriptions, a preliminary, high-level\nassumption was made that salt may comprise approximately 65% to 75% by volume\nwithin the evaluated interval. This estimate is not based on systematic\nwhole-interval chemical assays, does not represent a mineral-resource estimate\nand does not establish recoverable salt tonnage or suitability for cavern\ndevelopment. Detailed review of the existing core, measurement of\nrepresentative rock densities and determination of the salt percentage by\nvolume are recommended before the Company makes a decision regarding\nadditional drilling.\n\nThe approximately 278-metre gross salt interval extends from approximately 327\nto 605 metres and is based on the broader lithological record. The detailed\ndescriptions used for the preliminary salt-quality review cover the\n189.5-metre interval from 327.0 to 516.5 metres. Detailed review of the\ncomplete core record is required to quantify halite, mudstone and other\ninsoluble material throughout the full gross interval.\n\nThe study also noted that available descriptions from VTX-23-W-01 identified\nintervals containing more than 20% insoluble material. The existing\ninformation therefore indicates that salt quality is unlikely to be\nhomogeneous across the interpreted structures. Higher-purity and laterally\ncontinuous salt would generally reduce uncertainty associated with solution\nmining and potential cavern development, while mudstone interbeds, insoluble\nmaterial and structural variability may affect dissolution behaviour, cavern\ngeometry, operating performance and development risk.\n\nThe study concludes that the western block appears to contain salt of moderate\nquality and that additional drilling may improve confidence in the geological\nmodel without necessarily identifying materially better salt. The eastern\ntarget may contain cleaner salt; however, this interpretation remains based on\ngravity data and is unverified. The study further noted that, relative to\ncertain regional analogues, the currently available information indicates less\nfavourable conditions for commercial viability and funding confidence at\nRobinsons River, and that encountering cleaner salt alone may not materially\nimprove overall project confidence.\n\nStudy Recommendations\n\nFigure 3 presents three conceptual target locations. The study identified the\neastern target as the highest-priority conceptual exploration target because\nit offers the opportunity to confirm the depth, thickness and quality of the\nuntested eastern structure. The western gravity anomaly represents a secondary\ntarget that is closer to infrastructure but has weaker seismic support and may\ncontain salt of comparable or lower quality than the established western\nblock. Additional drilling within the western block could improve confidence\nin the geological and gravity models but is considered unlikely to materially\nimprove the currently interpreted salt quality.\n\nBefore advancing further drilling, the report recommends a staged technical\nprogram using the existing core and datasets. Initial work would include\ndetailed description and analysis of the VTX-24-W-02 core, representative\ndensity measurements, determination of salt percentage by volume, and\nevaluation of freshwater availability and disposal capacity. If the Company\nelects to proceed toward additional drilling or cavern evaluation, subsequent\nwork could include detailed well design and risk planning, an updated\ngeological and geophysical model, geomechanical and cavern-suitability\nstudies, and a field and storage-capacity assessment.\n\n\n\nFigure 3. Conceptual exploration target locations identified in the study,\nincluding NL1-A, NL1-B and NL2-A, shown in relation to modelled gross\nsalt-interval thickness, modelled depth-to-top-of-salt contours, existing\ndrill holes, seismic coverage, mapped roads and Vortex claim boundaries. The\nlocations are approximate planning concepts and do not represent approved\ndrill sites. NL2-A is located within the untested eastern exploration target.\n\nThe Company notes that it has not completed a preliminary economic assessment,\npre-feasibility study, feasibility study or comparable economic evaluation for\nthe Project. There is no assurance that the interpreted salt structures will\nsupport commercial salt extraction, brine production, hydrogen storage,\ncompressed-air energy storage or any other underground-storage application.\n\n“Lonquist’s work has provided Vortex with a much clearer and more\ndisciplined framework to advance the Robinsons River Project,” said Paul\nSparkes, Chief Executive Officer of Vortex. “The study has reinforced\nconfidence that a substantial salt-bearing system is likely located in the\nwestern block and identified meaningful exploration potential to the east. We\nnow have an outline of practical steps that can be taken to reduce technical\nuncertainty before committing to another major drilling campaign. Our\nimmediate focus will be on extracting the maximum value from the existing core\nand technical datasets.”\n\nCompany’s Next Steps\n\nThe Company will continue to review the Lonquist study and complete additional\ntechnical and commercial evaluation before determining whether to proceed with\nfurther work. This review will focus on the VTX-24-W-02 core, salt density and\ncomposition, water and disposal requirements, model refinement and\nland-package optimization. Any decision to advance drilling or development\nwill remain subject to technical results, commercial considerations,\nfinancing, permitting and contractor availability. No storage cavern,\nbrine-production facility or salt mine has been approved.\n\nQualified Person\n\nThe scientific and technical content of this news release has been reviewed\nand approved by Jared Suchan, Ph.D., P.Geo., Vice President of Exploration of\nthe Company and a “Qualified Person” as defined by National Instrument\n43-101.\n\nThe Qualified Person’s review included the final technical study by\nLonquist, and the geological, geophysical, drilling and interpretive\ninformation presented therein. The Qualified Person has not independently\nreprocessed all legacy seismic and gravity datasets underlying the study and\nhas relied upon the work and interpretations of Lonquist and the specialist\ncontractors identified in the study for those components.\n\nFor additional information concerning the Project and the Company’s\ndata-verification and quality-assurance procedures, readers are referred to\nthe Company’s technical report entitled Independent Technical Report on the\nRobinsons River Salt Property, dated July 31, 2023, available under the\nCompany’s profile on SEDAR+.\n\nTechnical Disclosure and Limitations\n\nThe work performed by Lonquist is a technical and planning study, and is not\nan independent technical report prepared in accordance with National\nInstrument 43-101 – Standards of Disclosure for Mineral Projects. It does\nnot contain a mineral-resource or mineral-reserve estimate, preliminary\neconomic assessment, pre-feasibility study or feasibility study.\n\nGravity and seismic interpretations are indirect exploration methods and do\nnot establish the composition, quality, continuity, recoverability or economic\nvalue of an interpreted salt structure. The gravity inversion is sensitive to\nassumed subsurface geometry and density values, and the eastern and western\ngravity anomalies remain untested exploration targets. References to potential\nsalt production, brine production, hydrogen storage, compressed-air energy\nstorage or other cavern applications are conceptual, and the suitability of\nthe Project for any such application has not been demonstrated.\n\nAbout Vortex Energy Corp.\n\nVortex Energy Corp. is an exploration stage company engaged principally in the\nacquisition, exploration, and development of mineral properties in North\nAmerica.

The study describes the\ninterval from 327.0 to 516.5 metres as a heterogeneous halite-bearing interval\ndominated by dark grey to black halite, with frequent mudstone interbeds,\nmuddy salt, mud skins, fractures and minor cleaner translucent salt veins.\nSeveral comparatively thick intervals were described as higher-quality salt;\nhowever, mud-rich salt and salt-cemented mudstone intervals may materially\nreduce the overall salt percentage and influence the suitability of the\ndeposit for potential commercial applications.\n\nBased solely on the available core descriptions, a preliminary, high-level\nassumption was made that salt may comprise approximately 65% to 75% by volume\nwithin the evaluated interval. This estimate is not based on systematic\nwhole-interval chemical assays, does not represent a mineral-resource estimate\nand does not establish recoverable salt tonnage or suitability for cavern\ndevelopment. Detailed review of the existing core, measurement of\nrepresentative rock densities and determination of the salt percentage by\nvolume are recommended before the Company makes a decision regarding\nadditional drilling.\n\nThe approximately 278-metre gross salt interval extends from approximately 327\nto 605 metres and is based on the broader lithological record. The detailed\ndescriptions used for the preliminary salt-quality review cover the\n189.5-metre interval from 327.0 to 516.5 metres. Detailed review of the\ncomplete core record is required to quantify halite, mudstone and other\ninsoluble material throughout the full gross interval.\n\nThe study also noted that available descriptions from VTX-23-W-01 identified\nintervals containing more than 20% insoluble material. The existing\ninformation therefore indicates that salt quality is unlikely to be\nhomogeneous across the interpreted structures. Higher-purity and laterally\ncontinuous salt would generally reduce uncertainty associated with solution\nmining and potential cavern development, while mudstone interbeds, insoluble\nmaterial and structural variability may affect dissolution behaviour, cavern\ngeometry, operating performance and development risk.\n\nThe study concludes that the western block appears to contain salt of moderate\nquality and that additional drilling may improve confidence in the geological\nmodel without necessarily identifying materially better salt. The eastern\ntarget may contain cleaner salt; however, this interpretation remains based on\ngravity data and is unverified. The study further noted that, relative to\ncertain regional analogues, the currently available information indicates less\nfavourable conditions for commercial viability and funding confidence at\nRobinsons River, and that encountering cleaner salt alone may not materially\nimprove overall project confidence.\n\nStudy Recommendations\n\nFigure 3 presents three conceptual target locations. The study identified the\neastern target as the highest-priority conceptual exploration target because\nit offers the opportunity to confirm the depth, thickness and quality of the\nuntested eastern structure. The western gravity anomaly represents a secondary\ntarget that is closer to infrastructure but has weaker seismic support and may\ncontain salt of comparable or lower quality than the established western\nblock. Additional drilling within the western block could improve confidence\nin the geological and gravity models but is considered unlikely to materially\nimprove the currently interpreted salt quality.\n\nBefore advancing further drilling, the report recommends a staged technical\nprogram using the existing core and datasets. Initial work would include\ndetailed description and analysis of the VTX-24-W-02 core, representative\ndensity measurements, determination of salt percentage by volume, and\nevaluation of freshwater availability and disposal capacity. If the Company\nelects to proceed toward additional drilling or cavern evaluation, subsequent\nwork could include detailed well design and risk planning, an updated\ngeological and geophysical model, geomechanical and cavern-suitability\nstudies, and a field and storage-capacity assessment.\n\n\n\nFigure 3.

There is no assurance that the interpreted salt structures will\nsupport commercial salt extraction, brine production, hydrogen storage,\ncompressed-air energy storage or any other underground-storage application.\n\n“Lonquist’s work has provided Vortex with a much clearer and more\ndisciplined framework to advance the Robinsons River Project,” said Paul\nSparkes, Chief Executive Officer of Vortex. “The study has reinforced\nconfidence that a substantial salt-bearing system is likely located in the\nwestern block and identified meaningful exploration potential to the east. We\nnow have an outline of practical steps that can be taken to reduce technical\nuncertainty before committing to another major drilling campaign. Our\nimmediate focus will be on extracting the maximum value from the existing core\nand technical datasets.”\n\nCompany’s Next Steps\n\nThe Company will continue to review the Lonquist study and complete additional\ntechnical and commercial evaluation before determining whether to proceed with\nfurther work. This review will focus on the VTX-24-W-02 core, salt density and\ncomposition, water and disposal requirements, model refinement and\nland-package optimization. Any decision to advance drilling or development\nwill remain subject to technical results, commercial considerations,\nfinancing, permitting and contractor availability. No storage cavern,\nbrine-production facility or salt mine has been approved.\n\nQualified Person\n\nThe scientific and technical content of this news release has been reviewed\nand approved by Jared Suchan, Ph.D., P.Geo., Vice President of Exploration of\nthe Company and a “Qualified Person” as defined by National Instrument\n43-101.\n\nThe Qualified Person’s review included the final technical study by\nLonquist, and the geological, geophysical, drilling and interpretive\ninformation presented therein. The Qualified Person has not independently\nreprocessed all legacy seismic and gravity datasets underlying the study and\nhas relied upon the work and interpretations of Lonquist and the specialist\ncontractors identified in the study for those components.\n\nFor additional information concerning the Project and the Company’s\ndata-verification and quality-assurance procedures, readers are referred to\nthe Company’s technical report entitled Independent Technical Report on the\nRobinsons River Salt Property, dated July 31, 2023, available under the\nCompany’s profile on SEDAR+.\n\nTechnical Disclosure and Limitations\n\nThe work performed by Lonquist is a technical and planning study, and is not\nan independent technical report prepared in accordance with National\nInstrument 43-101 – Standards of Disclosure for Mineral Projects. It does\nnot contain a mineral-resource or mineral-reserve estimate, preliminary\neconomic assessment, pre-feasibility study or feasibility study.\n\nGravity and seismic interpretations are indirect exploration methods and do\nnot establish the composition, quality, continuity, recoverability or economic\nvalue of an interpreted salt structure. The gravity inversion is sensitive to\nassumed subsurface geometry and density values, and the eastern and western\ngravity anomalies remain untested exploration targets. References to potential\nsalt production, brine production, hydrogen storage, compressed-air energy\nstorage or other cavern applications are conceptual, and the suitability of\nthe Project for any such application has not been demonstrated.\n\nAbout Vortex Energy Corp.\n\nVortex Energy Corp. is an exploration stage company engaged principally in the\nacquisition, exploration, and development of mineral properties in North\nAmerica. The Company is currently advancing its Robinson River Salt Project\ncomprised of a total of 942 claims covering 23,500 hectares located\napproximately 35 kilometres south of the town of Stephenville in the Province\nof Newfoundland & Labrador. The Robinson River Salt Project is prospective for\nboth salt and hydrogen salt cavern storage. The Company is also currently\nadvancing its Fire Eye Uranium Property in the Athabasca Basin, a region\nrenowned for its uranium deposits.\n\nOn Behalf of the Board of Directors\n\nPaul Sparkes\nChief Executive Officer, Director\n+1 (778) 819-0164\ninfo@vortexenergycorp.com\n\nCautionary Note Regarding Forward-Looking Statements\n\nCertain statements contained in this press release constitute forward-looking\ninformation within the meaning of applicable Canadian securities laws.\nForward-looking information relates to future events or future performance and\nis often, but not always, identified by words such as “could”,\n“intend”, “expect”, “believe”, “will”, “may”,\n“potential”, “planned”, “estimated”, “interpreted”,\n“conceptual”, “target”, “advance”, “continue”, “evaluate”,\n“assess”, “determine” and similar words or statements that certain\nactions, events or results “may”, “could”, “would”, “might” or\n“will” occur or be achieved.
