Bonanza Mine
King of the Pocket Mines
Discovered 1851, by Chileans, they took out a substantial amount of free gold.
Early 1870's acquired by James Divoll, Charles Clark, and Joseph Bray, sinking a shaft 1500 ft. in 1877. Big strike came in 1879, 990 lbs. of gold was removed in one week, valued over $300,000.
The mine yielded fortunes to Alonzo Colby, Edward Kiel, Albert Johnson, J.B. Harriman, and David R. Oliver, "All of Sonora".
No true record of the yield, but it ran into the millions.
Marker is at the intersection of North Washington Street (State Highway 49) and School Road, on the left when traveling north on North Washington Street.
