| Deposit | From Hausel, 1989, p. 157-158 ("the author" referring to Dan Hausel): "A group of short adits were driven into limonite-stained shears in gneiss [...]. On the west side of the gulch, two abandoned mines were examined in 1984. The southernmost adit was driven into granodiorite gneiss along a narrow shear. Four narrow copper- and limonite-stained veins were intersected in the mine workings. As short distance north, an adit extended less than 100 ft into the ocuntry rock. Across the gulch are more extensive workings, but when visited by the author in 1984, the adit was caved. In 1988, the author collected quartz vein samples from an adit on the hill in the NE4SE4 sec. 36, T14N, R84W, which contained visible gold. One sample of boxwork-filled quartz without visible gold assayed 19.0 ppm Au, 4.2 ppm Ag, and 0.013% Cu. Some remarkably rich gold specimens were found here[...]. In 1911 and 1912, some placer gold was also recovered from Purgatory Gulch [...]." |
