Base minerals were identified in 1923 and Mount Isa Mines Limited was established the following year. A small camp quickly acquired shops, a provisional school and other town services.
The railway opened in 1929 and the milling and smelting complex began operating in the early 1930s. These connections linked the inland field to Townsville and shaped both the mine and the city around it.
Mount Isa’s century of mining has produced extensive company, workforce and community records. Those papers are essential for understanding how a remote corporate mining settlement became a regional city.
Base-metal discoveries began the settlement that became Mount Isa.
