Canadian Large Projects


The State of Alaska engages in the review of large hard rock mining projects that have the potential to affect Alaska’s interests that depend on transboundary rivers. Generally, mining activities in northwest British Columbia do not require State of Alaska approval, because the proposed activities would occur outside of Alaska. However, if the activities could potentially affect downstream water quality, fish habitat, or fishery resources, the State of Alaska participates in the Environmental Assessment (EA) process administered by the British Columbia Environmental Assessment Office (EAO). For more information on the EA process and the EAO, please visit

Some mining projects proposed in British Columbia also require federal environmental review administered by the Canadian Environmental Assessment Agency (CEAA). For more information on the federal environmental review processes and the CEAA, please visit

B.C. Mining Projects

Mine projects proposed in British Columbia that the State of Alaska has reviewed, or is in the process of reviewing are listed under Current Projects. More detailed project information from the EAO may be found here. More detailed project information from the CEAA may be found here.

Other Projects

Outside of the provincial and federal Canadian environmental review processes, the State of Alaska may monitor the progress of specific mine projects located in British Columbia through reviewing published reports or direct communications with provincial and Canadian regulatory agencies. Such projects are listed under Other Projects.
