The quartzite on the Property is of the metamorphic type, of probable sedimentary origin, and occurs as large-amplitude folds formed in response to multiple episodes of folding. The controlling factors for the formation of the quartzite and for the presence of internal sub-units and structures are lithological (sediment precursor) and structural (recrystallization and formation of folds).

The Property area is located in the high-grade metamorphic terranes of the Grenville Province of the Canadian Shield. At least four ductile and one brittle deformation events have affected the area.

The Property hosts several map-scale sequences that host high purity quartzites. Rogue selected two of these sequences (“G” and “H”) as their primary drilling targets for potential further development. The “G” unit, hosting the South West and North East zones, trends SW-NE through the central portion of the Property, and the “H” unit, hosting the Centre North zone, is approximately 250 m to the north, in the northern sector of the Property (Figure 7-1). The width of the “G” quartzite unit varies along strike, reaching a maximum of 260 m, with an average thickness of 150 m.

The quartzite on the Property is generally coarse-grained, massive and locally fractured. It variably contains traces of biotite, muscovite, hematite, magnetite, ilmenite, fuchsite, rutile, and clusters of sillimanite with pyrite were occasionally observed. The different impurities cause the ch ........

SNC-Lavalin evaluated the potential for a quarry operation at Silicon Ridge to feed the direct ship feed with 180 kt per year of silica mineralization.

The mining method selected for this Project is a conventional truck and shovel, drill and blast quarry operation. Vegetation, topsoil and overburden will be stripped and stockpiled for future reclamation use. The mineralized material and waste rock will be mined with 5 m high benches, drilled, blasted and loaded into rigid frame haul trucks with hydraulic excavators.

The seasonal quarry operation is based on the contractor operating 5 days per week, 12 hours per day, and 6 months of the year during the warmer seasons. Overburden removal may take place during the winter to take advantage of the frozen ground conditions.

Two of the three Resource pits were designed for the Silicon Ridge project in order to target 20 years of production at 200 kt of blasted resource per year from the South West (SW) and the North East (NE) pit. The Central North (CN) pit was not designed for the 20 year plan due to a higher overburden depth than in the NE pit, although it is still within the Resource Estimate. The quarry has a nominal capacity to extract 200 kt per year of run of mine to produce approximately 180 kt per year of lump silica.

The SW pit is approximately 635 m long and 170 m wide at surface with a maximum pit depth from surface of approximately 105 m to a bottom of 885m elevation. The to ........
