Status | Proposed – In June, 2015, the Preliminary Final EIS was submitted for internal review. A PFEIS summary document can be found at the MNDNR website here. The SDEIS is available here. (The initial Draft EIS was rated as “Environmentally Unsatisfactory-Inadequate” by the U.S. EPA.)
Location | Superior National Forest, between Hoyt Lakes and Babbitt, MN
Type of Mine | 1,728 acre open pit – copper, nickel and precious metals
Estimated Mine Life | 20 years
Anticipated Output | 32,000 tons/day
- The low-grade ore (<1% minerals) is located in a sulfide ore body.
- 228,000,000 tons of tailings waste will be dumped into an existing waste basin that leaks.
- The mine and tailings basin sites will drain into the St. Louis River, a tributary to Lake Superior.
- 1,500 acres of wetlands will be destroyed or impaired
- A land exchange would be required “to acquire the Forest Service lands on which proposed mining operations would occur. The exchange would involve the transfer of about 6,650 acres of federal lands from public to private ownership, and up to about 6,722 acres of land from private to public ownership.” (MDNR fact sheet)
