The Alaska Juneau Gold Mining Company was incorporated in early 1897 under the laws of the State of West Virginia. The company purchased 23, patented claims located in Silver Bow Basin between Perseverance and Ebner mines for lode mining low grade gold ore.

Fred Worthen Bradley, mining engineer and president of the Bunkerhill and Sullivan silver/lead mine in Idaho, purchased a large interest in A.J. holdings in 1900. Later that year he became president of A.J. and president and consulting engineer of the Treadwell group. Robert A. Kinzie was resident engineer for both mines until Philip R. Bradley became resident manager from 1914-1920 and later consulting engineer. The Juneau and Treadwell mines were considered together for many years because their friendly stockholding interests were represented by interlocking managements.

The problems of putting A.J. on a paying basis, particularly after the ball mill constructed in 1917 failed to meet milling projections are documented in the correspondence along with various personnel difficulties. Bonds were sold to produce more capital to make needed changes in the mill, but times were difficult from 1917-1927 as described in the correspondence. By 1930 all bonds were retired and debts of A.J. were paid. The mine had a profit of $155,000 for the month of Dec. 1930. (Richard, T.A. A HISTORY OF AMERICAN MINING)

The limited file of correspondence (Box 3) covers a period of major development hurdles for the Alaska-Juneau, its management and board members. Some basic operation costs are documented in the CASH JOURNAL for A.J., 1897-1913 and the OPERATING COST LEDGER (crushing costs) for the three mines at Treadwell for the period 1912-1918. A CASH JOURNAL for the Treadwell-Yukon Company 1926-1938 is also with the records.
