Northshore Mining

Northshore Mining Company is proposing a project to relocate the West Ridge railroad at the Milepost 7 Tailings Basin, including the construction of a new embankment that will ultimately become part of the dam defining the final footprint of the tailings basin. The railroad is being relocated approximately 4,000 feet to the northwest, to accommodate the final expansion of the mine’s tailings basin. The area proposed for the tailings basin progression and related infrastructure is approximately 1,200 acres.

The site is located approximately six miles west of Silver Bay, in Lake County, Minnesota.
