High-grade manganese found in Northern MN (~50 miles W of Duluth)

A high-grade manganese deposit (highest grade yet found in the US) is located in northern MN, about 50 miles west of Duluth. It starts about 300+ feet underground. Be interesting to see what proposals are made to mine it. All manganese is currently imported into the US. Another mine is already being contructed in AZ. Manganese is used in batteries, so that makes this deposit one the battery makers will want to use–because it will add significantly to the US-made content of the batteries to be made.

The area is a major tourist magnet (the usual MN stuff: fishing, camping, I presume some hunting, and related outdoor activities).
