Mine Description

The Tillie Starbuck mine, held by H. L. Williams and associates, is near the head of Slate Creek Canyon, less than a mile east of the Davis-Dunkirk mill. This property was formerly owned by Major A. J. Pickrell who developed it with a few thousand feet of tunnels, winzes, and raises.

Lindgren (51) gives the following description: “The country rock is Yavapai schist intruded by dikes of light-colored rhyoliteporphyry. The foot-wall is said to be followed by a dike of rhyolite-porphyry 10 feet wide. The strike of the vein is N. 10° W., the dip 80° E., and the width 2 to 17 feet. The outcrop is persistent on the high ridge to the south, where the ore is largely oxidized. There are three ore shoots with backs of about 700 feet above the lowest tunnel level. This lowest tunnel is first a crosscut southeast to the vein for 640 feet and continues on the vein for 1,000 feet. It is claimed that 100,000 tons of $10 ore have been developed in the vein."

“The ore, which is mainly quartzose, contains from $10 to $17 to the ton, of which two-fifths is gold and three-fifths silver. (52) The ore carries free gold and pans colors. The quartz is rather fine grained, is milky with many small druses, and includes numerous sericitized rock fragments . . . The ore minerals are sparse pyrite and sphalerite in small grains and in places specks of pyrargyrite, which appears to be of hypogene origin.”

When visited in January, 1934, the present owners were extending an adit tunnel that had been driven for 1,400 feet by Major Pickrell and was designed to intersect the vein at a depth of 300 feet below the deepest winze.

(51) Work cited, pp. 119–20.

(52) Probably from 0.2 to 0.3 ounces of gold and 6 to 11 ounces of silver per ton.
