Based on analytical work performed in 2017, the current base scenario assumes the Victoria project will be developed in two stages, comprised of the sinking of a first shaft along with additional exploration, followed by a second shaft for production. |

Summary:
The Victoria property is situated at the junction of the SIC and the Worthington quartz diorite Offset Dyke, approximately 6.5 km northeast of Totten property. Other mineralized locations are known along the Worthington Offset between the Victoria property and the Totten Deposit. Two of these, the adjacent McIntyre deposit and the AER/Kidd Copper property, located 3 km further southwest from the Victoria property, were the objects of small mining operations.
Within the property, both the footwall contact of the SIC and the Worthington Offset Dyke dip steeply. Both intrude sheared and metamorphosed mafic volcanic and sedimentary rocks of the Stobie Formation. Zones of Sudbury Breccia occur throughout the property as discontinuous lenses. Late quartz diabase and olivine diabase dykes cross-cut all lithologies. Two dominant structural shear directions, one set trending northwest-southeast and the other trending northeast- southwest, have been defined and these control the distribution of mineralization on the property.
The Cu-Ni-PGM sulphide mineralization at the Victoria property is characterized by a complex assemblage of irregular lenses of chalcopyrite, pentlandite and pyrrhotite. The lenses dip and plunge steeply and are typically pipe-like.. The complex structural features of the property have caused remobilization of the sulphides and control the lateral extent and dimensions of the mineralization.

Mining Methods
- Mechanized Cut & Fill
- Paste backfill
Summary:
The underground mine will consist of a main shaft, a ventilation shaft and an adit, and underground supporting infrastructure including, but not limited to, maintenance facilities, refuge stations, ballast and shotcrete delivery systems, and explosive and detonator magazines.
The proposed maximum mine production rate is 3,500 t/d with an estimated maximum overall production capability of 5,500 t/d of ore and waste rock. Mine Product (ore) and waste rock will be hoisted to surface where it will be moved from the shaft to the loadout building via crushing and sampling processes, and eventually to the loadout building for transport. Ore will be loaded into trucks for shipment to Vale’s Clarabelle Mill. Waste rock will be transferred from the loadout building to trucks for transport to the PAG 2 waste rock storage pad.
