The Wasamac deposit is a gold deposit of replacement type with close coexistence of gold and pyrite disseminated in the altered Wasa Shear Zone. Hydrothermal alteration is well developed, and alteration minerals have distinct zonation from the orebody outward: albite-pyrite to carbonate-hematite to muscovite-chlorite. Gold mineralization is closely associated with these alterations, especially albite-pyrite alteration.

The Wasa Shear Zone runs through the centre of the property in an east-west fashion. This shear zone trends at an azimuth of 265°, has a 50° to 60° dip to the north and a maximum thickness of 80 m. It is characterized by the development of a strong mylonitic fabric and an intense hydrothermal alteration that destroyed the primary structures and textures of the protolith. Mineral assemblages of rocks within the shear zone consist of chlorite, carbonate, hematite, albite and sericite in the middle of the zone. Gold is associated with a dissemination of fine pyrite in the altered portions of the shear zone.

The Main Zone can be described as a well laminated mineralized zone. It is located near the centre of the property, within the Wasa Shear Zone and high grade areas display true widths of 10 m to 15 m (up to 25 m locally) over a strike length of 400 m. Gold mineralization is associated with quartz, carbonate, sericite, albite, pyrite and chlorite inside the shear zone. Visible gold is rare, and strong gold assays are generally associated wi ........

The Wasamac underground mine consist of five zones: Main Zone (“MZ”), Zone 1 (“Z1”), Zone 2 (“Z2”), Zone 3 (“Z3”), Zone 4 (“Z4”). It is located approximately 15 km west of Rouyn Noranda, Quebec, Canada, within the heart of the Abitibi gold mining camp. The mine design strategy is based on high speed development and Rail-Veyor® technology to complete the pre production infrastructures from years 2021 to 2023 and to achieve an average ore production rate of 6,000 tpd from years 2024 to 2031 when the mine is running at full capacity. The strategy is to recover higher grade zones in the early years of the Project.

Access into the mine is via twin declines extending from the portal located at 1,500 m east of MZ with a length of 2,456 m and grade of -7.50% down to the garage at 4990L above MZ. By using the twin decline design and the Rail-Veyor®, the system for removal of material is independent from the access for workers and supplies; this reduces the possibility of equipment collisions and travel delays experienced with trucking.

The Rail-Veyor® Integrated Top Down Long Hole Stoping Method was selected for the Wasamac Project based on the geometry of the mineralized zones, vertical dip, as well as economic factors. There are two types of mining methods: one with 40 m interval Rail-Veyor® main levels and another with 20 m interval Rail-Veyor® main levels. The 40 m interval involves accessing two levels of stopes using three longitudinal rubber tire drifts. T ........
