Administrative/Biographical History

The Aetna Mining and Milling Co., Ltd. was formed by John Swan, Arvid Lofgren, F.J. Vlosek, Fannie Shaw, Gus Hedland, Carl Amonson, and Fred Johnson in 1915. This group established the company's by-laws, were the directors of the company, and owned over two-thirds of the capital stock. Aetna Mine was located in the Lelande Mining District in Shoshone County. Originally, Carl Amonson sold four lode-mining claims to the company: Royal Queen, Tunnelsite, Best Resort, and Prince Albert. This transfer of claims was settled at the company's first meeting, March 16, 1915, at its office in Burke, Idaho.

From 1915 to 1938 the presidents were: John Swan, Jas. Murphy, C.S. Stone, P.J. Maggy, and Henry Day. Day had been the manager of the company and a member of the board of directors; he was elected president in 1932.

To develop its property the Aetna levied twelve assessments. The Hercules Mining Company purchased all delinquent shares and by 1938 controlled the majority of the stock. At a special meeting on January 10, 1938, the decision was made to transfer all property to the Hercules, and dissolve the Aetna.
