Eagle’s Nest is a sub-vertically dipping body of massive magmatic sulphides (MMS) in the form of a flattened pipe approximately 200 m long and 60 m thick, and currently defined vertically to 1,650 m. The deposit remains open along strike and occupies the northwestern margin of a vertically-inclined serpentinized peridotite dyke that is present in subcrop over a north-south strike length of about 500 m with a maximum width of about 75 m. The massive sulphides within the top 250 m are confined to a volume occupying the northwestern tip of this body, and are bordered to the southeast by a thicker zone of net-textured sulphide hosted by serpentinized peridotitic cumulates. Below 250 m, the massive sulphides can be found throughout the mineralization and, in some cases, into the surrounding granodiorite. The dyke is open at the north and south ends, and plunges very steeply to the south or vertically. The exact attitude of the sulphide-filled keel at the northern tip of the dyke is impossible to state because of the irregularity of the contact. Although a considerable amount of local deformation is evident around the contacts, particularly where they are occupied by massive sulphide, the body appears to be essentially still in place and not significantly deformed.

The Eagle’s Nest deposit mineralization is confined within a single ultramafic unit and, therefore, no geological domains are applicable to the resource estimation process. The deposit comprises two segments ........

The deposit is a high grade nickel-copper-platinum-palladium mineralized pipe up to 60 m across and 200 m length on strike. The host rock is a strong to very strong granodiorite. The designs assume the underground location of many facilities, including mineral processing, utilizing the competent host rock around the deposit.

The mining of the Eagle’s Nest deposit will be undertaken using bulk stoping techniques. The project will commence with the mining of aggregate from underground development. This aggregate will be used for surface infrastructure projects. The Eagle’s Nest deposit will be mined using highly automated underground mining techniques and paste tailings will be used to fill mined voids. Aggregate stopes will be used for additional storage of tailings.

The Eagle’s Nest deposit mineralized zone is overlain by 3 to 20 m of generally saturated organic matter, glacial till and sandy gravel. The deposit is a sub-vertical zone of massive magmatic sulphides in the form of a flattened pipe, 60 m across and 200 m long on strike. The surface elevation of the mine site is at 172 masl.

The deposit is well-suited to vertical bulk mining using blast hole stoping techniques. Initial underground access will be by twin ramps from surface to the processing plant level, followed by continuing twin ramps to the lower production levels. One of the lower twin haulage ramps will be equipped for electric trucks, to enable efficient haulage from the low ........
