(See Report X, p. 53; BuU. 18, p. 130.) Situated 1 mile southwest of Jamestown, on the southeastslope of Whiskey Hill. Holdings consist of the following claims:McCann, Mooney, Trio, Sobrante, and Mooney Mill Site, having a totalarea of 80 acres. Length along the lode of 5000 feet. Three veinscalled east, central (or boulder), and west, have been exploited. Theseveins have a course of N. 37° W., dip 60° NE. The lode—which is very 150 MINES AND MINERAL RESOURCES..

Average width of veins is about 10 feet. Thecentral vein consists partly of a body of solid quartz from 6 to 12 feetthick, and as a rule tlie values are too low grade to mine. The eastand west veins are in the form of stringer leads, consisting of a massof quartz stringers cutting the schist, carrying more or less free goldand sulphurets. The main footwall of the lode is serpentine with a hanging-wall ofCalaveras slates. Ore shoots occur west of central vein with a trendtoward the north. On the south end of the ore body a high-grade shootof ore 100 feet long by 3 feet wide is encountered on the contact betweenthe slates and serpentine. There are seven distinct ore shoots developedon this property
