The Proposed Project

Royal Nickel Corporation is proposing the construction, operation and decommissioning of an open pit mine for the purpose of mining a nickel deposit located 25 kilometres northwest of Amos, Quebec. The proponent plans to extract ore for 19 years, process higher-grade ore and, during this time, build up a temporary stockpile of lower-grade ore. At the end of the mining phase, the stockpiled lower-grade ore will be used to feed the mill for another 12 years, at which time the mine complex will be closed after 31 years of operation. The ore treatment facility will have an initial capacity of 52,500 tonnes per day, but will reach 105,000 tonnes per day by the fifth year of mining operations.
