Purepoint Applies Integrated 3D Modelling to Advance Uranium Targeting and Deploys Expanded MobileMT Program at Dorado Ready to Announce with Confidence?
Toronto, Ontario--(Newsfile Corp. - April 23, 2026) - Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) ("Purepoint") reports results from an integrated geophysical program combining airborne MobileMT surveys with advanced 3D structural modelling, completed by Expert Geophysics Limited, across three of its Athabasca Basin projects. By integrating MobileMT data into detailed 3D structural models, Purepoint has significantly improved its ability to identify and rank the subsurface structures most likely to host uranium mineralization, providing a more precise and capital-efficient framework for drill targeting. Building on these results, an expanded geophysical program will commence shortly at the Dorado Project, ahead of the Company's planned June 2026 drill campaign.
"The airborne passive EM (electromagnetic) results are changing how we understand and target uranium systems across our portfolio," said Scott Frostad, VP Exploration of Purepoint Uranium. "At Celeste East, the MobileMT data allowed us to view a detailed 3D model of the conductive structures that can control mineralization. At Russell South, we were able to resolve basement EM features that had been completely masked by broad subsurface conductive packages. The 3D structural modelling gives us a much clearer picture of where uranium is most likely to occur and how to target mineralization more effectively."
Highlights:
Refining Geological Understanding at Celeste East
At Celeste East, MobileMT data has been integrated with historic geological datasets to produce a detailed 3D model of the subsurface conductivity. The modelling, completed by Expert Geophysics, indicates that the previously interpreted east-west conductor is part of a broader folded conductive system within the project area.
The 3D interpretation has identified a structural fold with defined hinge zones and limbs, significantly refining the geological framework. Fold hinge zones are of particular exploration interest as they can create fractured pathways and structural taps for hydrothermal fluids, conditions associated with uranium precipitation in Athabasca Basin settings.
Creation of refined structural models enhances both drill targeting and the interpretation of future drilling results, allowing any mineralization encountered to be evaluated within a more complete structural context.
Celeste East is part of the Celeste Block Project, a 50/50 joint venture with IsoEnergy.

Resolving Subsurface Targets at Russell South
At the 100% owned Russell South, previous geophysical surveys were limited by shallow subsurface conductive layers that absorbed and distorted traditional airborne EM signals, masking the underlying basement geology. MobileMT, which uses naturally occurring electromagnetic signals to map structures at depth, enabled the Company to view conductive structures beneath this obstructive layer.
Subsequent 3D structural modelling of the inverted MobileMT data clearly defines previously unrecognized basement features that were inaccessible through conventional airborne EM methods, generating a series of drill targets with well-defined structural context.
Prioritizing Targets at Tabbernor
The 100% owned Tabbernor Project covers a large land position along a significant structural corridor in the Athabasca Basin. MobileMT results, combined with 3D structural modelling, have enhanced the definition of conductive trends across the project and established a ranked set of conductive corridors for follow-up exploration.
Next Phase: Dorado and Henday Lake Projects
Following the results at Celeste East, Russell South, and Tabbernor, Purepoint will commence expanded MobileMT surveys at Dorado and Henday Lake Projects.
At Dorado, the surveys are designed to produce the same quality of 3D structural model that has proven effective across the portfolio, focused not only on the structural settings around the Nova Discovery, but throughout all the other identified targets on the project. Integrating this model with existing drill results is expected to sharpen targeting and support more efficient deployment of drill resources ahead of the June 2026 drill campaign.
About MobileMT
Mobile Magnetotellurics is an airborne geophysical survey that maps subsurface resistivity and conductivity by measuring variations in naturally occurring EM signals over a broad frequency range 1. The method allows for deep penetration and, when combined with advanced inversion and 3D modelling, provides a detailed representation of geological structures and conductive pathways often associated with mineralization.
