The West Sunset Mining Company was a mining partnership, with claims held by individuals rather than a corporation. It appears to have been organized in November 1917. The claims in the Beaver Mining District, Shoshone County, originally known as the Portland Group, were owned by Eugene R. Day, George K. Garrett, David C. Smith, and E.G. Ellis.
In 1919, in order to further explore its property, the West Sunset Company rented a shaft of the adjoining Sunset Mine owned by Senator W.A. Clark of Montana. By 1921 the property was inactive, the only function of the company being to hold title to the property. In 1940 the property was purchased by the Portland Mining Company.
The records of the West Sunset Mining Company span the years 1911 to 1931. Included are financial statements, correspondence with suppliers and stockholders, financial ledgers and journals, tax returns and personnel records.
Since there are so few items in this record group, series designations were not made. However the arrangement of the material follows that of other records in the Day Mines group.
Removal of invoices, paid checks, bank statements, and duplicate materials reduced the size of this collection by 0.5 cubic feet.
The records of the West Sunset Mining Company are part of the records of Day Mines, Inc., donated to the University of Idaho by Henry Day in 1984 and 1985.
Initial processing of this manuscript group was done by Judith Nielsen in March and October 1988. Processing was completed by Michael Tarabulski in March 1992.
