Discovered in 1851 by Chileans, Bonanza Mine produced a substantial amount of free gold. In the early 1870's, James Divoll, Charles Clark, and Joseph Bray acquired it and sank a 1500-foot shaft in 1877. A major strike came in 1879, when 990 pounds of gold valued at more than $300,000 was removed in one week. The mine yielded fortunes to Alonzo Colby, Edward Kiel, Albert Johnson, J.B. Harriman, and David R. Oliver, all of Sonora, and although no true record of its total yield exists, it ran into the millions.
