A collection of approximately 20 items, consisting of location notices, receipts, assay certificates, informal accounting figures, letters, and notes primarily concerning the Lone Pine #1 and Lone Pine #2 quartz mining claims in Douglas County, which is located along the Nevada-California border, just south of Lake Tahoe. Other properties mentioned are the Tightner Mines of Sierra County, California (receipts and disbursements for 1915), the Hiawatha Mining Company assay certificate of 1906, and the Della Mine (account figures sheet and handwritten Notice of Location, 1906).
Charles C. Derby (1870-1942) was involved with all these properties, and this collection almost certainly comes from his personal papers. Previously, he had been the superintendent at the New Almaden quicksilver mines and the Fremont Grant gold mines in Mariposa County. The correspondence in this collection includes three letters to Derby by Robert E. Donovan, a Nevada mining engineer who served with the state’s bureau of mines safety before accepting a position with Standard Oil in Los Angeles.
All the material is clean and legible, with creasing from prior folds. Housed in a period cardstock envelope, which is rather worn with “Lone Pine Mining Claims” written in pencil on the front. Item #73808
