Also known as the Cerro Gordo Extension and Spear Mines.

From the California Journal of Mines and Geology, Vol. 47, No. 1, Jan. 1957:

30 unpatented claims are owned by the Silver Spear Mining Corporation, George Merritt, president, Santa Barbara.

Three parallel veins strike N. 30° W. and dip 70° W. in limestone and range from 1 foot to 3 feet in width. The ore minerals are lead and zinc carbonates and galena containing gold and silver. Principal development work has been done on the Lead Queen claim and consists of a 70-degree inclined shaft 200 feet deep with levels at 50, 100, and 200 feet. On the 100-foot level, a 50-foot winze has been sunk on the south drift 100 feet from the shaft. A 75-foot drift was driven from the bottom of the winze. Level workings from this shaft total approximately 900 feet.

Total production is reported to be $30,000 worth of ore. The property was last operated in 1940.
