A former surface and underground Mn-W-Fe mine located in sec. 29, T5N, R13E, about 3½ miles SE of Dutchwoman Butte, about 5 miles N of the eastern end of Theodore Roosevelt Lake, and 6 miles N of Roosevelt Creek. Produced 1953-1954. NOTE: Alternate coordinates provided: 33.7083N, 111.0361W.

Mineralization is an irregular ore body comprised of veinlets, seams, masses and blocks of ore hosted in the Dripping Springs Quartzite. The ore zone is 152.4 meters long, 18.29 meters wide, strikes N70W and dips 65NE. Ore control was the contact between limestone and quartzite. Limestone exists south of the mine workings. An associated rock unit is diabase.

The ore was mined from shaft workings and a few shallow opencuts. Additional exploratory work consisted of some bulldozer trenching. The workings are 19.81 meters in length and 12.19 meters deep.

Assay data: A grab sample contained 9.5% Mn, 3.0% Fe.
