Project summary

The Whabouchi mining project consists of the exploitation and development of a deposit of spodumene, a mineral rich in lithium. The project includes an open pit, a waste rock and tailings pile and a concentrator. The mine will produce approximately 200,000 tonnes per year of spodumene concentrate. The concentrate will then be transported to the processing plant in Shawinigan for conversion to lithium hydroxide and lithium carbonate. The total estimated operating time is 26 years.
