The Hubbard-Elliott Copper Company was incorporated in January of 1911 as a reorganization of the old Hubbard-Elliott Copper Mines Development Company of Alaska.
The company owned 35 patented claims, 5 mill sites with U. S. government titles and 84 unpatented claims, over 2,500 acres, covering 6 miles in Elliott Creek Valley.
In 1917, Hubbard-Elliott acquired an 8-12 interest in the adjoining U. G. I. group of 8 claims.
Elliott Creek is an affluent of the Kotsina River, about 15 miles above junction of the Kotsina with the Copper River.
The company's primary mine was located just west of Mt. Blackburn.
