The Swisshelm Mountains form a range about 15 miles long which extends NNW from the Chiracahua Mountains, on the east side of Sulphur Springs valley. A small valley, about 5,500 feet above sea level or some 1,000 feet lower than the nearby peaks, trends through the mining area.

These mountains are comprised of rock series from Cambrain to Tertiary. The Cretaceous and older rocks are intruded by granite which crops out over much of the western portion of the range. Its age is tentatively considered as Laramide (late Cretaceous - early Tertiary). Numerous small dikes of diorite cut the granite. A relatively thin, tabular mass of diorite porphyry crops out in the central part of the district.

The post-Cretaceous structural history of the Swisshelm Mountains includes intense folding, thrust faulting, and normal faulting.

The ore deposits of the Swisshelm district occur as replacements in Naco limestone.
