Overview

About the project

The Margane–Houlière–Grognon project consists of 263 claims, held 100% by MRB, in three blocks: Margane (10a, 117 claims), Houlière (10b, 83 claims) and Grognon (10c, 63 claims). It lies in the Lac-Saint-Jean Anorthosite Suite, in the Saguenay–Lac-Saint-Jean region of Québec.

Massive Fe–Ti–V oxide bands crop out under thin overburden. Over 17 samples, they average 63.5% Fe₂O₃ and 20.1% TiO₂, with up to 0.56% V₂O₅. Apatite-bearing rock adds phosphate potential, and chromium (up to 1.85% Cr₂O₃) and scandium (up to 110 ppm) are possible by-products. Historical SIGÉOM samples (GM 64920, GM 67504) and MRB's 2025 sampling are listed in the results below.

A 2026 heliborne survey outlines six strong magnetic bands, the targets of 44 planned trenches. Hydroelectric power lies 9 to 21 km away (Chute-des-Passes), a heavy-duty forestry road crosses the property, and the Port of Saguenay is about 160 km away.

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.

  1. Target 01 · Block 10c

    Massive oxide occurrences identified in 2025

    Massive oxide occurrences newly identified in 2025 on block 10c, in an area of thin overburden and excellent surface exposure.

  2. Target 02

    Six magnetic bands

    Strip and channel-sample the 44 trenches planned on the six strong magnetic bands of the 2026 heliborne survey, with fusion XRF and ICP (scandium) assays and QA/QC.

  3. Target 03

    Geometallurgy

    Test the separation of magnetite, ilmenite and apatite.

Regional context

Regional geological context

Information on neighbouring properties, reported by other companies. These are not MRB results, and mineralization on neighbouring properties is not necessarily indicative of mineralization on Margane–Houlière–Grognon.

  • 703 Mt at 7.2% P₂O₅ (M+I)

    Lac à Paul deposit (Arianne Phosphate)

    Arianne Phosphate's Lac à Paul deposit (Paul Zone and extensions), about 12.5 km from the project, has reported resources of 703 Mt at 7.2% P₂O₅ (measured + indicated) and reserves of 472 Mt at 6.9% P₂O₅ (proven + probable).
