The United Copper Company was a short-lived United States copper mining business in the early 20th century that played a pivotal role in the Panic of 1907. United Copper was incorporated in 1902 by F. Augustus Heinze, a copper magnate who had tussled for years with Amalgamated Copper for lucrative copper mines in Butte, Montana. The firm was incorporated in New Jersey with an authorized capital of US$80,000,000. United Copper combined Heinze interests in The Montana Ore Purchasing Company, The Nipper Consolidated Copper Company, The Minnie Healy Mining Company, The Corra Rock-Island Mining Company, and the The Belmont Mining Company.
