Vortex Energy Receives Final Technical Study Results for the Robinsons River Salt Project

Vortex Energy Receives Final Technical Study Results for the Robinsons River

Salt Project

Study confirms western salt structure, identifies an eastern exploration target and establishes a staged

technical pathway for further evaluation

Vancouver, British Columbia, August 06, 2026 – Vortex Energy Corp. (CSE: VRTX) (OTC: VTECF) (FSE: AA3)

(“Vortex” or the “Company”) is pleased to announce, further to its news release dated July 16, 2026, that

it has received the final technical study prepared by Lonquist Field Service (Canada), ULC (“Lonquist”) for

the Company’s Robinsons River Salt Project (the “Project”), located approximately 35 kilometres south of

Stephenville, Newfoundland and Labrador. The study integrates available geological, seismic, gravity and

drilling information to refine the interpretation of the Project’s subsurface salt structures, assess available

information regarding salt quality, identify potential future drilling targets and recommend a staged

program of further technical work. The Company notes that the study was not prepared pursuant to NI

43-101, nor by a Qualified Person (as such term is defined in NI 43-101).

Highlights

• Seismic, gravity and drilling data support the presence of a substantial western salt structure, with the

2024 drill hole VTX-24-W-02 intersecting an interval of approximately 278 m gross salt.

• Seismic interpretation identifies a potential incremental step-out west of VTX-24-W-02 where the salt

section may reach approximately 350 metres in thickness.

• Reprocessed gravity data indicate a large, untested eastern target that may be deeper and potentially

contain cleaner salt than the currently drilled western structure; this interpretation is based on gravity

data and remains unconfirmed by drilling.

• Next steps include detailed core analysis, source-water and disposal studies and technical planning.

The study confirms that Robinsons River hosts a thick halite -bearing system and identifies additional

exploration potential, particularly within the untested eastern block. It also establishes a clearer

framework for evaluating salt quality, subsurface geo metry, drilling risk and potential commercial

applications. Additional technical work will be required before the Company can determine whether the

Project is suitable for commercial salt production, brine production or underground energy storage. No

mineral resource or reserve, commercial production rate, storage -cavern design, storage capacity or

economic evaluation has been established for the Project.

Geological and Geophysical Interpretation

Figure 1 presents the final gravity -inversion salt -thickness model, and Figure 2 presents the spatial

differences between the seismic-derived and gravity-inversion interpretations. The latest Robinsons River

interpretation incorporates legacy seismic surve ys, airborne and surface gravity data, historical well

information and the results of the Company’s recent drilling program. The study concluded that the

western salt block is supported by the strongest combination of seismic, gravity and drilling control, with

VTX-24-W-02 confirming the presence of a substanti al halite -bearing interval within the interpreted

structure.

The study found that VTX-24-W-02 intersected an approximately 278-metre gross salt interval. The term

“gross salt interval” includes the broader halite -bearing interval and should not be interpreted as 278

metres of continuous, high -purity halite. Legacy s eismic data are considered sufficient to map the

interpreted minimum extent of the western structure and indicate that the salt section may thicken locally

toward a potential step -out target west of VTX -24-W-02. This proposed “Cloverleaf” location would

represent an incremental step -out from the existing well and has an interpreted salt thickness of

approximately 350 metres.

As part of the study, previously acquired airborne gravity data were reprocessed after it was determined

that the original processing had used an inappropriate terrain-correction. Revised terrain corrections were

incorporated into an updated gravity inversion, providing an appropriate basis for comparing the gravity

response with the seismic interpretation. Based on the seismic interpretation, the final gravity inversion

used fixed assumptions for the geometry of the Ship Cove Limestone structure and an assumed salt density

of 2.30 grams per cubic centimetre. Under those assumptions, the model indicates additional potential

salt east of VTX-24-W-02 and comparatively less salt immediately west of the drill hole than represented

by the seismic salt isochore mo del. The seismic and gravity datasets therefore provide related but not

identical interpretations. Seismic data support the Cloverleaf step -out west of VTX -24-W-02, while the

gravity-difference model indicates that the most substantial additional salt volume may occur farther east.

These differences reflect the indirect nature of both datasets and will require additional density

information and drilling control to resolve.

The updated interpretation also identifies a western gravity anomaly beyond the currently defined salt

structure and a larger eastern exploration target. The western anomaly is supported by gravity but occurs

in an area where the available seismic data are considered marginal in quality. The eastern target occurs

where a broad gravity low broadly coincides with seismic features interpreted as possible salt. The seismic

support for this target is considered to be ambiguous. The prospective top of the eastern salt structure

may occur approximately 1,100 to 1,300 metres below surface, and remains untested by drilling.

The western block is considered to be shallower, closer to existing infrastructure and supported by a higher

level of geological confidence. The eastern block is farther from infrastructure and deeper, but the gravity

response may indicate a greater proportion of lower -density material and th erefore potentially cleaner

salt. This remains an exploration hypothesis and has not been confirmed through drilling, core analysis or

open-hole density logging.

tested western block and the untested western and eastern gravity anomalies. Contours represent

modelled gross salt-interval thickness in metres. The inversion assumes a fixed geometry for the Ship Cove

Limestone structure and a salt density of 2.30 grams per cubic centimetre. The mapped thicknesses are

interpretive, have not been verified throughout by drilling and do not constitute a mineral reso urce or

mineral reserve estimate.

gravity inversion models a thicker salt interval t han the seismic interpretation, while positive values

indicate the reverse. Values are expressed in metres and represent model -to-model differences, not

measured salt thickness.

Salt Quality

The study reviewed the available descriptions of the VTX -24-W-02 core to provide a preliminary

assessment of salt quality. The study describes the interval from 327.0 to 516.5 metres as a heterogeneous

halite-bearing interval dominated by dark grey to black halite, with frequent mudstone interbeds, muddy

salt, mud skins, fractures and minor cleaner translucent salt veins. Several comparatively thick intervals

were described as higher-quality salt; however, mud-rich salt and salt-cemented mudstone intervals may

materially reduce the overall salt percentage and influence the suitability of the deposit for potential

commercial applications.

Based solely on the available core descriptions, a preliminary, high -level assumption was made that salt

may comprise approximately 65% to 75% by volume within the evaluated interval. This estimate is not

based on systematic whole-interval chemical assays, does not represent a mineral-resource estimate and

does not establish recoverable salt tonnage or suitability for cavern development. Detailed review of the

existing core, measurement of representative rock densities and determination of the salt percentage by

volume are recommended before the Company makes a decision regarding additional drilling.

The approximately 278-metre gross salt interval extends from approximately 327 to 605 metres and is

based on the broader lithological record. The detailed descriptions used for the preliminary salt -quality

review cover the 189.5-metre interval from 327.0 to 516.5 metres. Detailed review of the complete core

record is required to quantify halite, mudstone and other insoluble material throughout the full gross

interval.

The study also noted that available descriptions from VTX -23-W-01 identified intervals containing more

than 20% insoluble material. The existing information therefore indicates that salt quality is unlikely to be

homogeneous across the interpreted structur es. Higher -purity and laterally continuous salt would

generally reduce uncertainty associated with solution mining and potential cavern development, while

mudstone interbeds, insoluble material and structural variability may affect dissolution behaviour, cavern

geometry, operating performance and development risk.

The study concludes that the western block appears to contain salt of moderate quality and that additional

drilling may improve confidence in the geological model without necessarily identifying materially better

salt. The eastern target may contain cleane r salt; however, this interpretation remains based on gravity

data and is unverified. The study further noted that, relative to certain regional analogues, the currently

available information indicates less favourable conditions for commercial viability and funding confidence

at Robinsons River, and that encountering cleaner salt alone may not materially improve overall project

confidence.

Study Recommendations

Figure 3 presents three conceptual target locations. The study identified the eastern target as the highest-

priority conceptual exploration target because it offers the opportunity to confirm the depth, thickness

and quality of the untested eastern structure. The western gravity anomaly represents a secondary target

that is closer to infrastructure but has weaker seismic support and may contain salt of comparable or lower

quality than the established western block. Additional drilling within the western blo ck could improve

confidence in the geological and gravity models but is considered unlikely to materially improve the

currently interpreted salt quality.

Before advancing further drilling, the report recommends a staged technical program using the existing

core and datasets. Initial work would include detailed description and analysis of the VTX -24-W-02 core,

representative density measurements, determinati on of salt percentage by volume, and evaluation of

freshwater availability and disposal capacity. If the Company elects to proceed toward additional drilling

or cavern evaluation, subsequent work could include detailed well design and risk planning, an upd ated

geological and geophysical model, geomechanical and cavern-suitability studies, and a field and storage-

capacity assessment.

A, shown in relation to modelled gross salt -interval thickness, modelled depth -to-top-of-salt contours,

existing drill holes, seismic coverage, mapped roads and Vortex claim boundaries. The locations are

approximate planning concepts and do not represent approved drill sites. NL2 -A is located within the

untested eastern exploration target.

The Company notes that it has not completed a preliminary economic assessment, pre -feasibility study,

feasibility study or comparable economic evaluation for the Project. There is no assurance that the

interpreted salt structures will support commercial salt extraction, brine produ ction, hydrogen storage,

compressed-air energy storage or any other underground-storage application.

“Lonquist’s work has provided Vortex with a much clearer and more disciplined framework to advance the

Robinsons River Project,” said Paul Sparkes, Chief Executive Officer of Vortex. “The study has reinforced

confidence that a substantial salt -bearing system is likely located in the western block and identified

meaningful exploration potential to the east. We now have an outline of practical steps that can be taken

to reduce technical uncertainty before committing to another major drilling campaign. Our immediate

focus will be on extracting the maximum value from the existing core and technical datasets.”

Company’s Next Steps

The Company will continue to review the Lonquist study and complete additional technical and

commercial evaluation before determining whether to proceed with further work. This review will focus

on the VTX -24-W-02 core, salt density and composition, water and disposal requirements, model

refinement and land-package optimization. Any decision to advance drilling or development will remain

subject to technical results, commercial considerations, fin ancing, permitting and contractor availability.

No storage cavern, brine-production facility or salt mine has been approved.

Qualified Person

The scientific and technical content of this news release has been reviewed and approved by Jared Suchan,

Ph.D., P .Geo., Vice President of Exploration of the Company and a “Qualified Person” as defined by

National Instrument 43-101.

The Qualified Person’s review included the final technical study by Lonquist, and the geological,

geophysical, drilling and interpretive information presented therein. The Qualified Person has not

independently reprocessed all legacy seismic and gravity da tasets underlying the study and has relied

upon the work and interpretations of Lonquist and the specialist contractors identified in the study for

those components.

For additional information concerning the Project and the Company’s data -verification and quality -

assurance procedures, readers are referred to the Company’s technical report entitled Independent

Technical Report on the Robinsons River Salt Property, dated July 31, 2023, available under the Company’s

profile on SEDAR+.

Technical Disclosure and Limitations

The work performed by Lonquist is a technical and planning study, and is not an independent technical

report prepared in accordance with National Instrument 43 -101 – Standards of Disclosure for Mineral

Projects. It does not contain a mineral -resource or mineral -reserve estimate, preliminary economic

assessment, pre-feasibility study or feasibility study.

Gravity and seismic interpretations are indirect exploration methods and do not establish the composition,

quality, continuity, recoverability or economic value of an interpreted salt structure. The gravity inversion

is sensitive to assumed subsurface geom etry and density values, and the eastern and western gravity

anomalies remain untested exploration targets. References to potential salt production, brine production,

hydrogen storage, compressed-air energy storage or other cavern applications are conceptu al, and the

suitability of the Project for any such application has not been demonstrated.
