A surface and underground uranium prospect/deposit located on 5 claims in sec. 5, T7N, R13E, about 2½ miles due E of Greenback Peak, about 18 miles NNE of the Roosevelt Dam, on National Forest land. Owned by William Minarek of Globe.
Mineralization is a vein deposit with a manto-shaped orebody hosted in Dripping Springs Quartzite. The ore zone is 91.44 meters long and 0.61 meters thick. The deposit is near the base of the upper member of the Dripping Spring Quartzite. Mineral-containing ores lie along fractures and disseminated in the Dripping Springs Quartzite at the bottom of the Middle Mmember. In general it is less than 2 feet thick. An associated rock unit is diabase. Radioactivity in the favorable strata is between 0.25 and 1.0 mr/hr.
Workings include a 30 foot long adit,several prospect pits and small benches along the canyon wall and well as drill holes.
