Mine Life2035
The Voisey’s Bay mine is currently undergoing an expansion and transitioning from an open pit to an underground mine. The underground mining development will occur at the Eastern Deeps and the Reid Brook deposits. Construction for the Voisey’s Bay Mine Expansion (VBME) project began in 2016 and underground mining production was achieved in June 2021 of Reid Brook deposit, the first of two underground mines to be developed in the project. The start-up of the second deposit, Eastern Deeps, is expected by the second semester of 2022. As at December 2021 the project is 67% complete.

Summary:

The Voisey’s Bay Intrusion (“VBI”) is mafic in composition and is dominantly composed of olivine gabbro and troctolite with variable amounts of leucotroctolite, melatroctolite, olivine norite, gabbronorite and ferrodiorite. The Voisey’s Bay deposits are hosted by the VBI, which has been estimated to be at 1338 Ma old.

The VBI occurs in three intrusions. The first comprises the large, easterly plunging, troctolite chamber overlying the Eastern Deeps deposit. The second is the troctolite dyke, commonly referred to as the “feeder dyke” or “conduit.” It extends north of the Eastern Deeps chamber as a thin, flat-lying, body and then westward, with progressively steeper northerly dips eventually overturning to steep southerly dips. The Ovoid, Mini-Ovoid and Discovery Hill deposits occur in the steep, north-dipping segment while the Reid Brook deposit occurs in the south-dipping portion. The “conduit” ultimately approaches the top of the third body, the Western Deeps troctolite chamber below the Reid Brook deposit at a depth of about 1000 metres. The feeder dyke joins the two chambers.

There are four principal types of sulphide mineralization at Voisey's Bay: massive, leopard-textured, basal breccia, and disseminated in variable troctolite. The last three types are interfingered and cannot be correlated as distinct units.

The deposits making up the Voisey’s Bay Project include Discovery Hill, Eastern Deeps, Mini-Ovoid, Ovoid, Reid Brook and Southeas ........

Summary:

Voisey’s Bay is remote mining operations and processing site which is located approximately 35 kilometers (km) south of Nain, in northern Labrador. The 8,100 tonnes-per-day facility produces nickel concentrate and copper concentrate. Nickel concentrate produced at Voisey’s Bay is processed at VNL’s hydrometallurgical processing facility in Long Harbour, on the island of Newfoundland.

Voisey’s Bay includes:
- Ovoid open-pit;
- two undeground mines (Eastern Deeps and the Reid Brook deposits) are under development;
- Discovery Hill deposit is under development.

The Voisey’s Bay mine is currently undergoing an expansion and transitioning from an open pit to an underground mine. The underground mining development will occur at the Eastern Deeps and the Reid Brook deposits. Construction for the Voisey’s Bay Mine Expansion (VBME) project began in 2016 and underground mining production was achieved in June 2021 of Reid Brook deposit, the first of two underground mines to be developed in the project. The start-up of the second deposit, Eastern Deeps, is expected by the second semester of 2022. As at December 2021 the project is 67% complete. Reid Brook will utilize a drift and fill mining method.

In addition, an open pit mine is also being developed at Discovery Hill, which is expected to provide up to 5.3 Mt of potential ore grade material over its life of mine. The open pit mining at Discovery Hill will allow the mine to continue op ........
