A former medium-sized underground Zn-Pb-Ag (Bi-Be-Li-Ga-Cd) mine located on 14 claims in the center of sec. 10, T.18S., R.23E., west-central part of the Dragoon Range, about ½ mile south of China Peak. Discovered 1913. Produced 1913-1952. Held by Jonathan Gordan for many years (as of 1951). This mine is on the west side of a southeastward-trending gulch, at an altitude of approximately 6,400 feet.

In the ridge at the mine the succession of rocks, from lowest to highest, is exposed: Quartzite, light-colored and fine-grained, of Permian aspect, approximately 60 feet thick; gray shale, in part siliceous or novaculitic, with some impure limestone beds, locally metamorphosed to epidote, garnet, and other silicates (tactite), approximately 40 feet thick; bluish-gray limestone conglomerate and limestone, separated from underlying beds by low-angle fault, approximately 30 feet thick; thin-bedded, dark to brownish shale, in part sandy, caps eastern slope of the ridge. Presumably the conglomaritic limestone and overlying shale are Cretaceous.

The prevailing southeastward dip of the beds is modified by broad, low flexures in the mine. Also, faults which trend N.30ºW. and N.70ºE. have effected relatively small displacements. The side gulch immediately south of the mine apparently marks the location of a fault trending N.65º to 70ºW. and with its northern side downthrown. The main gulch east of the mine presumably marks a fault of northward trend, with its west side downthrown. Granite invades the sedimentary series on the west.

Mineralization is a wedge-shaped ore body hosted in Abrigo Limestone and containing sulfides, iron oxides and helvite in irregular manto-type bodies of pyrometasomatic limy silicates in impure, shaly Abrigo Limestone, where it is cut by faults. Irregular masses of contact silicates replace the impure, shaly limestone beds beneath the conglomeritic limestone.

Workings prior to 1947 included more than 1,000 feet of workings, largely within the Sulphide and Silver connecting adits. Workings are chiefly from adit levels. The Silver adit extends northward and connects with the Sulfide adit which extends west and southward. These two tunnels, together with their drifts and stopes, are distributed through an area approximately 330 feet long by 100 feet wide. In addition, there is the Mistletoe adit with approximately 200 feet of workings, and several shorted adits. Over 17,000 tons of ore were produced since 1913 but mainly during the period 1947 and 1951.
