The Queylus–Chibougamau group brings together four sub-projects in the Chibougamau mining camp of Québec: Queylus Porphyry Copper (5a) and Silver High Grade (5b), about 20 km south of Chibougamau on Route 167; C-Nord Cu–Godfather (5g), 7.5 km east of the town; and Kill Bill (5h), 30 km to the east-north-east.

At Queylus, historical drilling outlined a copper–gold–molybdenum porphyry system in tonalite south of Lac Chibougamau, with copper over 50 to 70 m from 25 m depth in its west, centre and east sectors. The neighbouring Silver High Grade showing on the Enard River, stripped in 2016, carries high-grade silver, tungsten, copper and gold, intersected from surface to 265 m along an IP trend of about 2 km; the two sub-projects can be combined.

Godfather lies, in MRB's interpretation, on the north–south mineralized axis that runs from the former Bruneau mine to the C-3 zone of Chibougamau Independent Mines; a high-grade copper boulder was found there in 2024. Kill Bill, on the north flank of the Chibougamau pluton like the former Lemoine VMS mine, hosts the Icon massive sulphide lens and the Uma-Yubari and Hanzo exhalative horizons.

1. Target 01 · Block 5a – Target 1 around 11-490-19
   The 14 historical holes around 11-490-19 all stopped before 110 m. Proposed: about 3,600 m of close-spaced drilling around the hole.
2. Target 02 · Block 5a – Depth and IP anomalies
   Two to three deep holes below 300 m in the porphyry system, and drilling of the induced polarization (IP) anomalies.
3. Target 03 · Block 5b – Silver High Grade: stripping and depth
   Channel-sample the full width of the 2016 stripping, drill 2–3 holes below 300 m with follow-up of QU-12-02, and drill the strong IP anomaly to the east.
4. Target 04 · Block 5g – Compilation and ground work
   Compile the 9 historical drill holes and maps of Godfather, then carry out ground geophysics and prospecting.
5. Target 05 · Block 5g – Projected C-3 axis below 200 m
   Drill the projected axis of the C-3 zone below 200 m: a conceptual target at about 300 to 600 m depth along the Bruneau – C-3 corridor (MRB interpretation).
6. Target 06 · Block 5h – Targets 1 to 3 at Icon
   Drill targets 1 to 3 around the Icon lens. Target 3: a new interpretation suggests the KB horizon is offset to the north and untested in the east of the property, where VTEM anomalies lie (Ressources Yorbeau press release, 2020-02-27).
7. Target 07 · Block 5h – Uma-Yubari horizon
   Test the Uma-Yubari exhalative horizon, recognized over 600 m at surface in 2021.
8. Target 08 · Block 5h – Borehole EM
   Borehole EM surveys in holes KB-05E, KB-09 and KB-10, where casings are in place.
