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.
