IDM encourages the public, interested parties and stakeholders to review and comment during the next month.

In 2017, IDM submitted an Application for an underground gold mine at Red Mountain, mill and tailings site in the adjacent Bitter Creek Valley, water treatment facilities, access road from Highway 37A just north of Stewart, BC and powerline interconnection from BC Hydro grid. The Application Review phase included environmental and socioeconomic reviews with dozens of technical working group members and stakeholders, with respectful and thorough consultation with the Nisga’a Nation.

Canadian Environmental Assessment Act Review

The Project was referred by the BC Environmental Assessment Office (“BC EAO”) to the Minister of Energy, Mines and Petroleum Resources and the Minister of Environment for consideration and approval on August 28, 2018 (see IDM Press Release on August 29, 2018). The Ministers’ have 45 days to make their decision.

The Project is also subject to a coordinated review by the CEA Agency under the Canadian Environmental Assessment Act, 2012 (CEAA 2012). The Project is now entering the final public consultation stage of the federal process. IDM anticipates receiving Federal approval from the Minister of Environment and Climate in late 2018 or early 2019.
