Dumont nickel project, Canada
Name and Location
Dumont nickel project, Quebec, Canada.
Client
Royal Nickel Corporation.
Project Description
The Dumont project has proven and probable reserves of 1.18-million tonnes grading 0.27% nickel, 107 parts per million of cobalt, 0.019 g/t palladium and 0.009 g/t platinum.
A bankable feasibility study (BFS) has demonstrated a technically and economically sound project, with an after-tax net present value of $1.1-billion.
Nickel production at the project is expected to be among the top five nickel sulphide operations worldwide (by nickel production), with initial nickel production expected at 73-million pounds a year, increasing in the fifth year to an a average of 113-million pounds a year for the remainder of the 20-year mine life.
The BFS envisages a conventional openpit mine/mill operation using conventional drilling, blasting and loading, with a combination of hydraulic and electric rope shovels and truck haulage.
The mine is designed to produce ore at about twice the capacity of the mill, which will mitigate the risk of feed shortages and allow for the highest-value material to be prioritised and processed accordingly. As a result, an ore stockpile will be generated to continue to feed the mill for an additional 13 years at the end of the mine life, with the tailings deposited in the openpit.
The process plant will be constructed in two phases. Phase 1 will have an initial average throughput of 52 500 t/d using a single semiautogenous mill and two ball mills for grinding and cyclones for desliming, as well as conventional flotation and magnetic separation to produce a nickel concentrate also containing cobalt and platinum-group elements.
Value
The project is estimated at $1.19-billion.
