Vortex Energy Provides Update on Technical Research and Exploration Activities to Advance the Robinsons River Salt Project

Ongoing Research and Technical Investigations to Support Hydrogen Storage Potential

VANCOUVER, British Columbia, July 17, 2025 (GLOBE NEWSWIRE) -- Vortex Energy Corp. (CSE: VRTX) (OTC: VTECF) (FSE: AA3) ("Vortex" or the "Company") is pleased to provide an update on its ongoing research initiatives at the Robinsons River Salt Project in partnership with the University of Alberta. These studies are aimed at evaluating the suitability of the salt complex for potential underground hydrogen storage applications.

The results from core hole VTX-23-W-1 were presented by researchers at the University of Alberta (U of A) at GeoConvention in Calgary, which detailed the mineralogical and petrological characteristics of the Robinsons River Salt Complex. Key findings included the identification of distinct lithological units and assessment of halite purity, impurity fractions, and sealing properties, all factors critical to evaluating underground hydrogen storage potential.

Further laboratory investigations by U of A researchers are ongoing on core samples from VTX-23-W-2. X-ray Diffraction (XRD) analysis has been completed on selected intervals to determine mineralogical variability with depth. Porosity and permeability testing has begun, with data from the first test sample currently under review. Geomechanical studies are also underway using a tri-axial core holder and CT-scanned samples to evaluate wellbore stability under simulated stress conditions. One of the prepared samples is shown in Figures 1.

Paul Sparkes, CEO of Vortex, commented:

"We're excited by the progress at the Robinsons River Salt Project and the valuable insights from our partnership with the University of Alberta. These studies are key to evaluating the potential for underground hydrogen storage at our Project."
