Editing Leadville (section)

==History==
===Oro City===
Placer gold was discovered in California Gulch in 1860, during the Pikes Peak Gold Rush, and the town of Oro City sprung up near present-day Leadville. The boom was brief, however, and Oro City never became a major settlement. The placer gold mining was hampered by heavy brown sand in the sluice boxes.

===Discovery of Silver===
In 1874, gold miners at Oro City discovered that the heavy sand that impeded their gold recovery was the lead mineral cerussite, that carried a high content of silver. Prospectors followed the cerussite to its source, and by 1876, had discovered several lode silver-lead deposits. The city of Leadville was founded near to the new silver deposits in 1877 by mine owners Horace Austin Warner Tabor and August Meyer , setting off the Colorado Silver Boom. By 1880, Leadville was one of the world's largest silver camps, with a population of over 40,000.

Famous Confederate scout, cowboy and stage actor with "Buffalo Bill" Cody's travelling revue, Texas Jack Omohundro died here in the summer of 1880, of pneumonia, just one month shy of his 34 birthday. He was living there on a small estate with his wife, ballerina Giuseppina Morlacchi. It was during this period that Leadville saw its most dangerous days, finally brought under control by little known American Old West lawman Mart Duggan.

In 1882, the Tabor Opera House hosted Oscar Wilde on his lecture tour of the West, one of many celebrities who graced the city. Mayor David H. Dougan invited Wilde to tour the Matchless silver mine and open their new lode: "The Oscar." Wilde later recounted a visit to a local saloon, "where I saw the only rational method of art criticism I have ever come across. Over the piano was printed a notice - 'Please do not shoot the pianist. He is doing his best.'"

Around 1883, famous outlaw Doc Holliday moved to Leadville, only a short time after the gun fight at the O.K. Corral. On August 19, 1884, Holliday shot ex-Leadville policeman, Billy Allen, after Allen threatened Holliday for failing to pay a $5 debt. Despite overwhelming evidence implicating him, a jury found Holliday not-guilty of the shooting or attempted murder.

In its early years, Leadville was the site of some famous mining swindles. When the Little Pittsburg mine exhausted its rich ore body, the managers sold off their shares while hiding the real condition of the mine from other stockholders. “Chicken Bill” Lovell dumped a wheelbarrow of rich silver ore into a barren pit on his Chrysolite mining claim in order to sell the claim to Horace Tabor for a large price; but Tabor had the last laugh when his miners dug down a few feet farther and discovered a rich ore body. Later, the manager of the Chrysolite mine fooled an outside mining engineer into overestimating the ore reserves of that mine.
===Decline===

The city's fortunes declined with the repeal of the Sherman Silver Purchase Act in 1893, although afterwards there was another small gold boom. Mining companies came to rely increasingly on income from the lead and zinc.

The district is credited with producing over 2.9 million troy ounces of gold, 240 million troy ounces of silver, 1 million short tons of lead, 785 thousand short tons of zinc, and 53 thousand short tons of copper

During World War II, Leadville was a popular spot for visits by soldiers at nearby Camp Hale, but only after the town acted to curb prostitution; until then, the United States Army declared the town off-limits for its personnel. The Army Air Forces built the Leadville Army Airfield northwest of the city. The war also caused an increase in the mining of molybdenum at the nearby Climax mine. At one point the mine produced 75 percent of the world's molybdenum.
