History
of Butte, Montana: a Timeline
Butte, Montana, was built on copper mining, ambition, and grit.
This timeline traces the people, events, and milestones that shaped the Copper City, from mining booms and labor struggles to waves of cultural change, all across one wildly historic city.
Butte’s evolution is reflected in its fluctuating population, a theme woven throughout this timeline. To orient you, Butte had 34,494 residents in 2020, according to the Census. By 2024, that number was estimated to have risen to 35,480.
1850s
1864 July
Prospectors found gold in and around Silver Bow Creek. About 500-1,500 people lived in Butte during the 1860s.

1872
The Butte mining camp was in decline, most surface gold was gone, and what remained was trapped in quartz with no mill to process it. William A. Clark came to Butte, bought up quartz claims at very low prices, and eventually acquired a quartz mill. With the mill, Clark could process the miners’ ore, an early move that positioned him to profit from what came next.
1874
Gold played out completely; it went quickly between 1864 and 1874. By the time it was gone, Butte’s population had significantly decreased; estimates suggest only 61-241 people remained in Butte.
1875 January
William Farlin staked the Travona mine after learning the black rock around Butte contained silver, which helped revive the dwindling mining camp. Shortly after, more silver and tons of copper were discovered around Butte. However, at this point, the miners were not interested in copper.

Rivals blasted the family’s financial problems to the press, Heinze was pushed out, and depositors rushed to both institutions to withdraw their funds. The fallout was initially intended to affect Heinze and the trusts, but it quickly got out of hand, and the Panic of 1907 became an economic nightmare for the entire nation.
