An He occurrence located in secs. 28, 32, 33, 34 & 35, T20N, R26E and in secs. 2, 4 & 10, T19N, R26E, G&SRM, approximately 17.7 km (11.0 miles) NNE of Joseph City and 21.4 km (13.3 miles) NNW of Holbrook. Operated during the period 1961-1975. Operated by Kerr-McGee Corporation and Eastern Petroleum.

Mineralization is a helium gas deposit hosted in the Late Permian Coconino sandstone. The ore body is 99.06 meters thick. The deposit lies within the Pinta Anticline, an E-W-trending, doubly plunging structure with about 100 feet of relief, which dips on its flanks typically 0.5 - 1.5°. The Moenkopi formation's micaceous siltstone and silty mudstone form an impermeable cap. The porosity of the sandstone may be as high as 20%. The Pinta Dome fault offsets the NE flank of the dome. Local rocks include rocks of the Chinle Formation.
