A former small surface and underground Pb-Zn-Ag-Cu-Au-Mo-W-As-Cd occurrence/mine located in secs. 33 & 34, T16S, R30E and secs. 3, 4, 5, T17S, R30E, G&SRM, (Rustler Park 7.5 minute topo map), 6 miles NW of Paradise, about 26 miles S of San Simon, near Gleeson and near Hand's Pass, on National Forest land (located claims). Discovered 1880. First produced 1881. The Hidden Treasure claim was first located in the district - now part of the Hilltop Mine. Owned at times by the Hilltop Silver Lead Mines Company; Hilltop Metals Mining Company; Piedmont Mines, Incorporated; American Zinc, Lead, and Smelting Company; and operated by the Queen Mining Company (1973).

Mineralization is a polymetallic deposit hosted in quartzite, in fissure veins and in irregular replacement lenses and bodies in banded and tilted, silicified Mississippian to Permian limestones and older quartzites. The ore body is lenses, shoots, pockets and chimneys with a width of 15.24 meters and a length of 33.53 meters. Controls for ore emplacement included brecciation along faults & fissures. Ores are base metal sulfides and carbonates with wulfenite, often argentiferous, and scheelite. The ore zone is 33.53 meters long and 15.24 meters wide. This mine is famous for the fine and abundant wulfenite specimens it produced. Ore control was in part due to brecciation along faults and fissures in the quartzite and limestone. Locally pipes of massive sulfides (1-6 feet diameter) follow fractures into limestone for distances of up to 50 feet. Associated rocks include Pliocene diorite. Local rocks include Cretaceous to Late Jurassic sedimentary rocks with minor volcanic rocks.

Local geologic structures include NE-SW faults.

Workings include extensive surface and underground openings including several tunnels, open cuts, and short adits. They total some 6,096 meters in length and 457.2 meters deep. The Hilltop Mine consists of 4 major levels with 3 of those being connected, and with over 5.5 miles of underground workings. The Kasper Tunnel is 3,000 feet long with 6,000 feet of workings; the Gray Tunnel is 2,000 feet long with 3,000 feet of workings; the Rhem tunnel is 3,700 feet long with 3,000 feet of workings.

Production was a total of some 30,000 tons of base metal sulfide ore produced intermittently from the early 1910's to about 1954. Best production years were 1924 - 1927. Shipments were made by burro & wagon in the 1880'S. Several carloads of ore were shipped to El Paso in 1902-1906.

Analytical data results: 2-5 ounces/ton Ag, 10-25% Pb, 5-15% Zn, 0.1-5.61% Cu, 10-12% Fe, 2-10% Mo.
