Butte mining company Montana Resources now has the go-ahead from state officials to expand its waste storage facility northeast of town and the Berkeley Pit.

The Montana Department of Environmental Quality (DEQ) issued its final decision Friday allowing the copper mining company to build the Yankee Doodle Tailings Impoundment 50 feet higher.

Copper mining company Montana Resources is now one step away from receiving approval from state regulators to expand its permanent mine tailings storage facility in Butte.

Since 1986, Montana Resources (MR) has been sending the slurry of waste from its open pit copper and molybdenum mine in Butte up to the Yankee Doodle Tailings Impoundment, which sits uphill and northeast of the Berkeley Pit.

State officials say a proposed expansion to Montana Resources’ tailings impoundment in Butte next to its active copper mine there won’t impact groundwater.

The Montana Department of Environmental Quality wants public feedback on a mining company’s year old plan to expand the Yankee Doodle Tailings Impoundment above Butte.

Montana Resources wants to raise the height of the impoundment by 45 to 75 feet over about 336 acres.
