Overview

About the project

Lac Fabien is a vanadium–iron–titanium (V–Fe–Ti) project of 90 claims covering 5,209 ha, about 50 km north-east of La Tuque in the Mauricie region of Québec. MRB acquired it from SOQUEM Inc. in late 2023.

The project lies 3 km from the CN railway and about 150 km from the Port of Saguenay, and the Lac Sylvio camp is on site. At an elevation of 450 m, MRB sees potential to generate green energy through the regenerative braking of electric locomotives.

SOQUEM carried out grab sampling, stripping and channel sampling in 2021 and 2022 (263 m of channels). A 946 km drone magnetic survey outlines a favourable zone of vanadiferous magnetite about 6 km long and 0.8 km wide. Davis tube magnetic concentrates average 1.43% V₂O₅ and 61.8% FeT (186 tubes), and the mineralized zone averages 57 ppm scandium (100 samples). MRB cut 716 m of channels in 2024; the 627 samples are awaiting assays.

Some exploration results presented here are historical in nature and have not been verified according to current NI 43-101 standards. Grab samples are selective by nature and are not necessarily representative of the mineralization on the property.

Exploration targets

Targets for the next phase

Exploration targets are conceptual in nature and subject to further exploration work. They are not mineral resources.

Target 01
Favourable zone, 6 km × 0.8 km
A 946 km drone magnetic survey by SOQUEM outlines a favourable zone of vanadiferous magnetite about 6 km long and 0.8 km wide, where trenches are planned.
Target 02
2024 trenches
Assay the 627 samples of 2024, channel-sample the 575 m of trenches ready for sampling and excavate the 580 m of cleared trenches.
Target 03
Geometallurgy
Geometallurgical tests for iron, vanadium, titanium and scandium, followed by an NI 43-101 technical report and drilling.
