VanadiumCorp Reports Results of Geophysical Survey at Lac Doré Vanadium Project

Vancouver, British Columbia — April 16, 2026 — Leads & Copy — VanadiumCorp Resource Inc. has released the results of an Ambient Noise Tomography (ANT) geophysical survey conducted at its Lac Doré Vanadium Project in Québec.

The survey, carried out by CAUR Technologies Inc., provides a three-dimensional shear-wave velocity model to aid geological interpretation and guide future exploration efforts.

The ANT survey, completed in early 2025, covered approximately 7.4 km² and utilized 98 passive seismic nodes. Continuous ambient seismic data was recorded and processed to create a 3D velocity model reaching an interpreted depth of about 450 metres.

CAUR Technologies Inc. has provided an interpretation summary of the survey results.

A laterally continuous low-velocity corridor has been identified, coinciding with the known vanadium-titanium-magnetite (VTM) mineralized trend at the surface.

The feature appears to increase in lateral continuity at depth within the investigated volume.

The observed lower seismic velocities, relative to expected values for magnetite-rich lithologies, are interpreted to reflect localized fracturing and/or hydrothermal alteration within or adjacent to the mineralized zone.

The geometry of the interpreted feature is sub-vertical, suggesting it may represent a structural or alteration corridor intersecting the stratigraphic sequence.

CAUR Technologies Inc. noted that these interpretations are preliminary and based on indirect geophysical measurements. The results do not constitute direct evidence of mineralization and must be validated through drilling and integration with geological data. While the ANT survey provides a framework to prioritize targets for future drilling, there is no guarantee that such targets will lead to the discovery of additional mineralization.

The results are based on the technical report titled “Ambient Noise Tomography Survey – Lac Doré Vanadium Project (CAU-24-007)”, dated February 3, 2026.

VanadiumCorp intends to integrate the ANT dataset with historical drilling and downhole data, and planned three-dimensional geological and geophysical modelling to refine exploration targeting and reduce geological uncertainty. Additional work, including follow-up geophysics and drilling, will be required to test the interpretations derived from the ANT survey.

The Lac Doré Project hosts a vanadiferous titanomagnetite system within the Chibougamau mining district of Québec.

The most recent mineral resource estimate for the project, prepared by CSA Global with an effective date of October 27, 2020, is considered a historical estimate under National Instrument 43-101.

The historical estimate reports:

In-Situ Resource:

Measured & Indicated: 214.93 Mt grading 0.40% V₂O₅, 27.1% Fe, 7.1% TiO₂

Inferred: 86.91 Mt grading 0.40% V₂O₅, 28.0% Fe, 7.6% TiO₂

Magnetite Concentrate Basis:

Measured & Indicated: 52.82 Mt grading 1.3% V₂O₅

Inferred: 22.55 Mt grading 1.2% V₂O₅

The company has not independently verified the data or assumptions underlying this estimate.

Significant work will be required to upgrade or verify the historical estimate, including verification of historical drill data and sampling procedures; implementation of modern QA/QC protocols; confirmatory and infill drilling; updated geological and resource modeling; and preparation of a current mineral resource estimate in accordance with NI 43-101.

André Gauthier, P.Geo., a Qualified Person as defined under National Instrument 43-101 and a director of the Company, has reviewed and approved the scientific and technical information contained in this release.

VanadiumCorp Resource Inc. is focused on advancing vanadium-titanium-iron projects in Québec, including its flagship Lac Doré Project.
