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.
The current development scenario for the Victoria project calls for the sinking of two shafts to access the deposit (a production shaft and a ventilation shaft).
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.
Rock from PAG 1 will be crushed and used in paste backfill process.
In 2022, work continued on project terrain connected with preparing selected elements of the surface infrastructure for further develo ........
