Primarily produced from chlorargyrite. Boulders of ore to 2-3 tons were found. Production totals were between 20-40 million dollars from an area one mile long by half mile wide.
Structure: The White Pine Range is a typical N-S-trending Basin and Range fault block composed of a sequence of Paleozoic carbonate and clastic sedimentary rocks intruded by two Cretaceous- age granitic stocks.

Alteration: Deposit was oxidized

Commodity: Ore Materials: native silver, chlorargyrite, bromargyrite, acanthite, aurorite, minerals Gangue Materials: calcite, quartz, pyrite, iron and manganese oxides, oxide copper minerals

Deposit: Replacement orebodies. Host rock is a brecciated sandy brown limestone. Calcite "stalactites" fill fractures with brecciated material. Also vitreous gray banded, quartz vein with pyrite and a small amount of copper oxide minerals and manganese oxides.

Deposit type: Polymetallic replacement

Development: A group of Reese River miners discovered silver on the western slopes of White Pine Mountain in fall of 1865 and organized the White Pine Mining District. In 1868, a rich discovery of silver ore on Treasure Hill resulted in rush to White Pine. The town of Cave City was formed at the foot of the northern side of the hill at 8,000 feet near some caves that served as early shelters. By 1868, Cave City was renamed for promoter W. H. Hamilton and by mid-winter the population had grown to near six hundred. rush to White Pine, only to find mining was impossible because of the extreme cold. A post office was established in August 1868. Within two years, more than thirteen thousand mining claims were recorded in the district and 195 White Pine mining companies were incorporated. In 1869 the town's population was estimated at 10-15,000, possibly as many as 30,000. The 1870 Census showed 3,913 residents, but in 1873, the shallow ore began to peter out and a decline set in, hastened by disastrous fires in 1873 and 1885. By 1888, the ore had been exhausted and the town was soon deserted. There have been some recent, 1980s efforts to develop more ore in the mine area, including a small attempted heap-leach operation by Einar Erickson?s promotional group. In 1985, ownership of the Hidden Treasure Mine, one of the Treasure Hill properties, was listed as F. W. Lewis Co.

Geology: Host rock is a brecciated sandy brown limestone. Calcite stalactites fill fractures with brecciated material. Also vitreous gray banded, quartz vein with pyrite and a small amount of copper oxide minerals and manganese oxides.

Ore(s): Ore was localized by carbonate lithology, adn by fracturing and brecciation.
