Rose Lithium-Tantalum Mining Project — Public comments invited on the draft environmental assessment report and potential conditions

What is happening?

March 17, 2021 — The Joint Assessment Committee (the Joint Committee) comprising of representatives from the Impact Assessment Agency of Canada (the Agency) and the Cree Nation Government is conducting a federal environmental assessment of the proposed Rose Lithium-Tantalum Mining Project, located north of the Cree Nation of Nemaska, Quebec, in the Eeyou Istchee territory.

The Joint Committee invites the public and Indigenous peoples to comment on the draft Environmental Assessment Report, which includes the Committee's conclusions and recommendations regarding the potential environmental effects of the project and their significance, and the proposed key mitigation measures and follow-up programs.

The Joint Committee also invites comments on the draft potential conditions prepared as part of the environmental assessment of the project. Final conditions would become legally-binding on the proponent if the project is allowed to proceed.

The Joint Committee recognizes it is more challenging to undertake meaningful public engagement and Indigenous consultation in light of the circumstances arising from COVID-19. The Committee continues to assess the situation, adjust consultation activities and provide flexibility as needed in order to prioritize the health and safety of all Canadians and conduct meaningful engagement with interested groups.

How can I participate?

Comments can be submitted online by visiting the project home page on the Canadian Impact Assessment Registry (reference number 80005). All comments received will be published online as part of the project file.

Written comments in either official language will be accepted until April 16, 2021.

Will there be more opportunities to participate?

This project has benefited from several public and Indigenous consultation opportunities. This is the final public comment period in the process.

What is the proposed 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.
