Rose Lithium-Tantalum Mining Project

Critical Elements Corporation is proposing the construction, operation and decommissioning of an open pit lithium and tantalum mine located approximately 38 kilometres north of Nemaska, in Quebec. As proposed, the project includes the operation of an open pit, waste and tailings impoundment area, an industrial ore processing facility and the option of transforming concentrate off-site. The mine would produce about 4,500 tonnes of ore per day over a 17-year life span. The project would last 26 years in total with the construction and restoration phases.
