The discovery at Voisey’s Bay was ultimately significant for three reasons:
- The ore was rich in content. In fact, the famed Ovoid zone had an average grade of 2.8% nickel.
- Much of the ore was near the surface. This would help to minimize extraction costs.
- The deposit was close to tidewater. This reduced the costs associated with transporting ore to ships
The Deposit
The Voisey’s Bay deposit is world-class in terms of its grade and size. With 141 million tonnes of ore, the deposit has significant grades of nickel, copper, and cobalt:
- 1.63% nickel
- 0.85% copper
- 0.09% cobalt
The resource is located in the three main zones: Ovoid, Eastern Deeps, and Reid Brook. The Ovoid represents less than 23% of the total tonnage, but more than 42% of the metal in the deposit.
