The thorium mineralization in the Lemhi Pass area of southeastern Lemhi County, Idaho, is directed along simple to complex shear and fracture zones, and reopened copper and gold-quartz veins and lodes, in impure quartzitic and phyllitic rocks of the Precambrian Belt series.

The ore deposits occur in the belt of calcareous rocks, an area bounded by the Cambrian quartzite on the west and the lake beds on the east. They are in flat and steeply dipping veins, parallel with the strike of the country rocks; some of the larger and more productive deposits occur at the intersection of the steep and flat veins.
