Name of the Project
Rose lithium/tantalum project.

Eeyou-Istchee – James Bay, in Quebec, Canada.

Project Owner/s
Critical Elements Lithium Corporation.

Project Description
The Rose project will produce technical-grade spodumene concentrate for the glass and ceramics industry, and chemical-grade spodumene concentrate for conversion for use in batteries for e-mobility.

The project will also include the production of a tantalite concentrate.

Envisaged is a standard truck-and-shovel openpit mining operation using conventional lithium processing technologies.

The mine will excavate 26.3-million tonnes of ore grading an average of 0.87% lithium oxide and 138 parts per million of tantalum pentoxide after dilution.

The mill will process 1.61-million tonnes of ore a year to produce an average of 224 686 t/y of technical- and chemical-grade spodumene concentrates and 441 t of tantalite concentrate.

The ore is contained in several parallel and continuous, shallow-dipping pegmatite dykes outcropping on surface.

The ore zones are open at depth and a future underground operation is possible.

Over the 17-year life-of-mine, the openpit will excavate 182.4-million tonnes of waste rock and 10.9-million tonnes of overburden.

The average strip ratio is 7.3 t of waste per tonne of ore.

Contract mining will be used for the removal of the overburden, while Critical Elements will undertake the mining of all hard-rock material using its equipment fleet and operators.

A standard froth flotation process will be used to produce technical- and chemical-grade lithium concentrates and a tantalum concentrate.

The mineral process plant will comprise beneficiation and dewatering areas.
