Project summary
The Anctil–Nemenjiche project comprises 231 claims covering 12,924 ha in two blocks south of Chapais: Anctil (113 claims, 6,314 ha) and Nemenjiche (118 claims, 6,610 ha). The claims are being transferred to MRB from Ressources Tectonic.
Both blocks cover the Caopatina Formation, which hosts IAMGOLD's Nelligan gold deposit in the same mineralized corridor, the belt that runs from the former Lac Shortt mine through Anctil and Nelligan to Nemenjiche. At Anctil (4a), the Lac Anctil gold showing lies on a 6 km magnetic anomaly where four drill-ready targets have been defined; historical drilling there intersected visible gold.
Nemenjiche (4b) lies about 3.5 km from the former Joe Mann mine and about 15 km from Nelligan, with EM conductors and historical gold intercepts along the Caopatina Formation.

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.
Targets for the next phase
Exploration targets are conceptual in nature and subject to further exploration work. They are not mineral resources.
- Target 01 · Block 4a – Validate the historical Anctil drilling
Compile and validate the historical drill holes of the Lac Anctil showing, including LA-87-6, before drilling. - Target 02 · Block 4a – Targets 1 and 2 (Nelligan type)
Drill targets 1 and 2 on the magnetic gradient of the Lac Anctil showing, a Nelligan-type setting in the Caopatina Formation. - Target 03 · Block 4a – Targets 3 and 4
Two further targets on the 6 km magnetic anomaly, east and north-west of the Lac Anctil showing. - Target 04 · Block 4b – Nemenjiche fold noses
Till sampling and prospecting at the fold noses of Nemenjiche, around the EM conductors.
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 Anctil–Nemenjiche.
- Nelligan deposit (IAMGOLD). At its Nelligan deposit, in the same belt, IAMGOLD reported 2.23 g/t Au over 77 m in drill hole NE-26-272. (Source: IAMGOLD press release, 2026-10-27)
