VanadiumCorp Reports Results of Ambient Noise
Tomography Survey at Lac Dore Vanadium Project
04/16/2026
Vancouver, British Columbia –TheNewswire -April 16, 2026 – VanadiumCorp Resource
Inc. (TSX-V: VRB | FSE: NWNA | OTC: VRBFF) (“VanadiumCorp” or the “Company”) reports
the results of an Ambient Noise Tomography (“ANT”) geophysical survey completed at its
100%-owned Lac Doré Vanadium Project located near Chibougamau, Québec.
The survey was conducted by CAUR Technologies Inc. and provides a three-dimensional
shear-wave velocity (“Vs”) model to support geological interpretation and assist in
targeting future exploration programs.
Survey Overview
The ANT survey was completed in early 2025 over an area of approximately 7.4 km² using
98 passive seismic nodes. Continuous ambient seismic data were recorded and processed
to generate a 3D velocity model to an interpreted depth of approximately 450 metres.
Data quality and coverage were considered sufficient to support interpretation within the
limits of the methodology.
CAUR Interpretation Summary
The results of the ANT survey are interpreted as follows:
• A laterally continuous low-velocity corridor has been identified that spatially
coincides with the known vanadium-titanium-magnetite (“VTM”) mineralized trend
at surface.
• The identified 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 that it may
represent a structural or alteration corridor intersecting the stratigraphic sequence.
“These interpretations are preliminary in nature and are 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. The ANT survey provides a
framework to prioritize targets for future drilling; however, no assurance can be given that
such targets will result in the discovery of additional mineralization. ” CAUR
Technical Information
The ANT survey was conducted by CAUR Technologies Inc. The results referenced herein
are based on the technical report titled:
“Ambient Noise Tomography Survey – Lac Doré Vanadium Project (CAU-24-007)” , dated
February 3, 2026.
Geophysical interpretations are inherently non-unique and model-dependent. The ANT
method provides indirect measurements of subsurface properties and does not replace
drilling as a means of confirming geological interpretations or mineralization.
Strategic Significance
The recently completed Ambient Noise Tomography survey at the Lac Doré Property
provides a new three-dimensional view of subsurface geology, comparable to an
ultrasound image of the ground. By recording naturally occurring seismic vibrations, the
survey maps variations in the physical properties of rocks at depth, which can be indicative
of geological structures, zones of fracturing, or areas of alteration commonly associated
with mineral systems.
The ANT survey results suggest that the known vanadium-bearing geological trend
identified at surface may extend to depth and could be associated with a broader structural
feature. While these results are encouraging and support the Company’s exploration
model, it is important to note that the Ambient Noise Tomography survey does not directly
detect mineralization and does not confirm the presence, grade, or continuity of economic
mineralization at depth.
Use of Results and Next Steps
The Company 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.
About the Lac Doré Project
The Lac Doré Project hosts a large vanadiferous titanomagnetite system located within the
Chibougamau mining district of Québec.
The most recent mineral resource estimate for the project was prepared by CSA Global
with an effective date of October 27, 2020. This estimate is considered a historical
estimate under National Instrument 43-101.
Historical Mineral Resource Estimate (October 27, 2020)
Historical Mineral Resource Estimate (October 27, 2020)
The mineral resource estimate for the Lac Doré Project was prepared by CSA Global with
an effective date of October 27, 2020 and is considered a historical estimate under
National Instrument 43-101.
The 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 historical estimate was prepared using industry-standard estimation methodologies
applicable at the time, including geological modeling, drill data interpretation, and
reasonable assumptions regarding mineral continuity. However, the Company has not
independently verified the data or assumptions underlying this estimate.
The resource categories reported (Measured, Indicated, and Inferred) are consistent with
the classification categories defined by the Canadian Institute of Mining, Metallurgy and
Petroleum (CIM) Definition Standards; however, a Qualified Person has not completed
sufficient work to classify the historical estimate as current mineral resources.
The Company is not aware of any more recent mineral resource estimates for the Lac Doré
Project.
The historical estimate is considered relevant as it demonstrates the presence of a large
vanadiferous titanomagnetite system; however, its reliability is uncertain due to the lack of
recent verification, modern quality assurance and quality control (QA/QC) review, and
updated geological modeling.
Significant work will be required to upgrade or verify the historical estimate, including but
not limited to:
• 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.
A Qualified Person has not done sufficient work to classify the historical estimate as
current mineral resources, and the Company is not treating this estimate as current.
