Structure: The area has been uplifted intruded by igneous rock and denuded by erosion.

Alteration: The deposit has been silicified by hydrothermal activity, and oxidized.

Commodity: Ore Materials: sphalerite, galena, chalcopyrite, gold, chalcocite, cerussite, cuprite, malachite Gangue Materials: quartz, chalcedony, hematite, calcite, brochantite, limonite, wulfenite, vanadinite, adularia

Deposit: Deposits in the district are mainly WNW -trending fissure veins (34), irregular in shape, some flat-lying and saucer-shaped. Vein material consists of a breccia of country rock fragments with vuggy quartz cement. Veins occur en echelon along the western contact of a quartz monzonite intrusive. Most production was from oxidized and weathered veins. In some cases, gash-type fractures are filled with vein material that was later brecciated.

Deposit type: Epithermal vein, Comstock

Development: The first claims were staked on the Duplex property in 1897 by G. F. Colton , and the Searchlight Mining District was founded July 20, 1898. The Searchlight Post Office was established in October 1898. The Quartette Mining Company, formed in 1900, became the mainstay of the Searchlight District, producing almost half of the area's total output.Searchlight began to boom in 1902 and reached its peak year in 1907. In May, 1902, a 16-mile narrow-gauge railroad was built down the hill to the company's mill on the Colorado River. After 1907, the boom crashed and production fell sharply. Mines were operated mainly by lessees after 1911. Total production up to 1940 amounted to $4.5 million. On March 31, 1907, the 23.22-mile Barnwell and Searchlight Railroad connected the town with the then main Santa Fe line from Needles to Mojave. By 1919 trains were operating over the B and S Railroad only twice a week. A severe washout on September 23, 1923, halted traffic completely and train service was never restored. In the 1900s, Searchlight reportedly reached a maximum population of 5000 people and was far larger than Las Vegas at the time. A "Mines of Searchlight" map dated October 1906, shows that there were well over 300 mining claims in the area at that time. Eventually, the gold and silver production dwindled with the decreasing grade of the ore and by 1927, there were only about 50 people left in Searchlight.
