A Au occurrence/property located in the old Union Pass District area.
O. K. GROUP.
The 0. K. group lies about 2 miles west of Union Pass, at an elevation of 3,600 feet. It almost joins the San Diego group on the northwest, being situated on the continuation of the same hogback ridge, which here is several hundred feet high. At the time of visit it was owned by J. D. Eichardson and heirs, of Kingman, but it is reported to have been acquired since by the Gold Pass Mining Company, of Los Angeles.
The property is developed mainly on the northwest, at the end of the ridge, which here falls off in steep slopes into a deep valley, beyond which the deposits have not been traced. The developments consist mainly of two tunnels driven on or near the contact of the intrusive rhyolite with the granite. The drifts are situated about 50 feet apart vertically. The upper has a length of 150 feet and the lower of about 250 feet. From the upper a winze descends to or near a crosscut in the lower.
The ore consists of iron-stained and pyrite-bearing quartz and altered rock, and locally contains also some galena. It is irregularly distributed or pockety. That taken from the upper drift, which looks better than the lower drift, is said to have averaged about $20 a ton in gold, and samples of the foot-wall granite taken 10 feet apart throughout the length of the drift are reported to have assayed from $1 to $4 a ton. Some high-grade ore occurs in small bodies of fine sandy material inclosed by the iron-stained lower-grade ore, quartz, and rock.
