The mine was located about 1870 and ^Patented. SAN DIEGO COUNTY. 661 was worked for about five years prior to 1891 by ex-Governor Water-man. A three-compartment shaft was sunk 600 feet and levels drivenat 180 feet, 235 feet, 315 feet, 400 feet, 500 feet, 600 feet, north andsouth on the vein. The total production was about $2,000,000.

Note.—Pay chute above should read, shoot. 662 GEOLOGY AND MINERAL RESOURCES. The great production of the bonanza days came from a shoot some300 feet long which was worked to a depth of 500 feet. Below thislevel the continuation of this shoot was greatly reduced in size and atthe 600-foot level it was worked with a length of 90 feet. Below the600-foot level a winze was sunk 30 feet, still in ore. The rake of theshoot is to the southeast. At 600 feet the vein is 87 feet from theshaft on the cross cut and the ore body is 160 feet southeast from theshaft on the vein. The ore in places attained a width of 20 feet.
