Zebulon Pike reported gold in Colorado in present day Park County, Colorado as early as 1807, but it wasnt until rich discoveries near Denver in 1858 that sparked the Pikes Peak Gold Rush. Since then, gold mining has been a major industry in Colorado, with significant lode and placer discoveries throughout the state. Over 1 million ounces of gold has come out of Summit County in central Colorado, both as lode and placer deposits.
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the Crime of 73, but silver mining continues today. United States mines produced 1,170 tons of silver in 2014, 17% of the silver it used. 63% of consumption was imported, from Mexico, Canada, Peru and Chile, and the remainder was derived from recycling.
