The Eureka Mining District

In 1864, prospectors from Austin, Nevada, discovered rock containing a silver-lead mixture on Prospect Peak, beginning development of the Eureka Mining District as a vital part of Nevada's mining heritage and future. By 1878, the population of Eureka and nearby Ruby Hill was over 9,000, and the district ranked as Nevada's second richest mineral producer after the Comstock. Rich ore veins of silver, lead, and other base materials supported enormous underground mine development and financial risk, with Eureka's greatest production occurring from 1870 to 1890. By 1900, changing market conditions reduced demand for the district's materials, many mines closed, and only a few smaller mines continued operating until the 1920s. More recently, the district has seen revival through heap leaching, a technology that profitably and efficiently processes rock containing trace amounts of gold. Near the top of the hill, the Fad Shaft survives as a remnant of earlier mining and as the district's last underground mining operation. Although the Fad claim was discovered in 1906, mining did not begin until the 1940s, when geological theory suggested ore lay 2,500 feet below the surface. Sporadic mining continued from the 1940s to the 1960s, but at 2,465 feet miners encountered severe flooding only 35 feet from their target, and the shaft closed soon afterward without ever producing ore. Around Eureka, rock piles, open shafts, abandoned mining equipment, and a few surviving headframes remain as reminders of the district's past, while modern heap leaching and reclamation practices reflect how mining technology and its effects on the landscape have changed.
