If permitted, the Pebble Mine will enable the development of a mining district many times larger than the Pebble Mine lease, substantially increasing the likelihood that mining operations will adversely impact Bristol Bay ecosystems.

Seven different mining operators have established claims since the Pebble Limited Partnership, and initiated leases covering 793 square miles, an area ten times larger than Washington D.C.
