A former Ag-Au-Zn-Cu-Pb occurrence/mine located in the NW¼SW¼ sec. 18, T17N, R14W, G&SRM, 19 miles E of Yucca, on Bureau of Land Management administered land. Additional workings are located in T16½N, R14W, and, in secs. 12&13, T17N, R15W. Owned by E.L. Hollingsworth, Arizona (1966). Operated by Behunin, Utah (1974).

SIAMESE GROUP.
The Siamese Group mine is situated on the southern part of the east slope of the Hualpai Mountains, in the Cedar Valley district, at about 5,000 feet elevation. It is best reached from Yucca, from which it is 23 miles distant in a southeasterly direction. A wagon road extends to a point within 5 miles of the mine, with which connection is made by trail.
The property comprises nine claims. It is reported to make a very good surface showing and to be promising in copper. Since 1907 it has been owned by the Arizona-Southwestern Copper Company, with headquarters at Kingman.
The property is in the prospect stage and is developed principally by two 15-foot shafts, cuts, and surface pits. Water is present on the property, and water level is believed to lie at about 100 feet below the surface.
The country rock seems to be the pre-Cambrian granitoid complex. It is intruded by "porphyry" near by. The deposits are contained principally in a large fissure vein, which strikes north-northwest, and the quartz croppings have a length of nearly 2 miles.
The gangue is principally quartz, and the ore contains copper, lead, silver, and gold. Average samples of the ore collected from an ore shoot about 4 feet in width in the lower part of the two shafts on Siamese claims Nos. 1 and 2 gave assay returns about as follows: Silver, 14 ounces to the ton; copper, 4 per cent; lead, 9 per cent; zinc, 2 per cent. Another test, made of a presumably select sample from the same shaft, though the manner of collection is not stated, is said to have given 10.5 per cent of copper, 16 per cent of lead, and 35 ounces silver and $1.60 in gold to the ton. The ore is said to be good concentrating ore.

Mineralization is a replacement deposit hosted in granite. The ore body is 3,218.6 meters long. Associated rocks include Neoproterozoic dolerite. Local rocks include Early Proterozoic granitic rocks.
Workings include unspecified underground openings.
Analytical data results: Sample assays: 5.01 ounces Ag/ton, 0.01 ounce Au/ton, 2.6% Pb, 4.3% Zn, 0.25% Cu (Arizona Department of Mineral Resources files). Result: 14 ounces Ag/ton, 9% Pb, 4% Cu .
