Historical NoteReturn to Top

The Basin Montana Tunnel Company was incorporated in 1927 by William H. Hax, New York City, and Carl J. Trauerman of Butte.

The company had the Gray (Grey Eagle) and Comet patented claims and more than 100 additional patented and unpatented claims, about 21,000 acres, on the west side of High Ore Gulch in the Cataract District, extending about three miles south of the Comet Mill to the Great Northern Railroad station at Fuller, Montana, and about 6 miles northeast of Basin, Montana. The claim contained silver, gold, lead, and zinc ore. The company had the only custom milling plant in Montana outside of Anaconda, and the company was the largest producer of base metals in Montana outside of Butte. The company employed 100 men.

The mine was considered played out by 1941, and the company was inactive by 1949.
