The Leadville mining district, located in the Colorado Mineral Belt, was the most productive silver-mining district in the US state of Colorado. It is located immediately east of the town of Leadville. Oro City, an early Colorado gold placer mining town located about a mile east of Leadville in California Gulch, was the site of the single richest placer gold strike in the entire Pikes Peak gold rush. In just seven years, ten tons of gold were mined from California Gulch.
Cumulative production through 1963 was 240 million troy ounces of silver, 3 million troy ounces of gold, 987 million tonnes of lead, 712 million tonnes of zinc, and 48 million tonnes of copper. The district also produced byproduct bismuth, and iron-manganese ore.

Famous quotes containing the words mining and/or district:
“In strict science, all persons underlie the same condition of an infinite remoteness. Shall we fear to cool our love by mining for the metaphysical foundation of this elysian temple? Shall I not be as real as the things I see? If I am, I shall not fear to know them for what they are.”
—Ralph Waldo Emerson (1803–1882)
“Most works of art, like most wines, ought to be consumed in the district of their fabrication.”
—Rebecca West (1892–1983)
