Waterloo claim


A former small surface Mn mine located in the center of the SW¼ sec. 22, T.23S., R.24E., on a hilltop ¾ mile South of the Briggs shaft, and 0.2 miles (ca. 322 m) S of Tintown, on private land. Location estimated from a mine map found in U.S. Bureau of Mines Information Circular 7990, P. 11. Owned at times, or in part, by the Calumet & Arizona Mining Co. and the Phelps Dodge Corp. (1930).

Mineralization consists of lenses and irregular bodies of manganese oxides along fissure zones in Pennsylvanian-Permian Naco Group limestone. The orebodies are near dikes and sills, and faulting and associated brecciation. The fissure zone strikes N10W, steeply dipping, in Naco Limestone. High-grade orebodies range from 1 to 3 feet (ca. 91 cm) in width and from 15 to 70 feet (ca. 21 m) in length. Ore concentration includes bornite replacing pyrite. Alteration was gossan with Mn and Fe oxides induced by hydrothermal metamorphism. At least 2 nearly North-South fissures in Naco Limestone. An associated rock unit is the Sacramento Hill Stock.

Local structures include common pre-mineralization faulting and tilting. The main fault directions are N10W to N40E and S30W to N50W.

Workings include 3 or 4 shallow open cuts. Ore has been taken from seven or more shallow open cuts that extend some 400 feet (ca. 122 m) along strike. The deepest working was an open pit 15 to 20 feet (ca. 6 m) in diameter and about 25 feet (ca. 8 m) deep. About 1,500 tons of manganese oxide were produced in 1917-1918.
