Our Mission, History & What We Do


The mission of the WMMI is to educate the public about the history and continuing contributions of mining, ranching and other supporting industries in the American West.


What We Do

Open since 1970, the Western Museum of Mining and Industry (WMMI) is committed to preserving and interpreting the rich mining and industrial history of Colorado and the American West.

Experience a unique and interactive museum designed to educate the public about the importance, and controversies, of mining and industry and the impact on our daily lives.

Prominent exhibits at WMMI include:

  • What’s Mined is Yours Mineral Display
  • Walk-Through Mine Shaft (built with the Colorado School of Mines)
  • 1895 Corliss Steam Engine and other WORKING machines
  • Colorado's largest collection of Fluorescent Minerals
  • Chilean Miners Rescue Pod
  • Authentic Representations of Assay and Mining Offices

Outside, visitors can inspect two historic mining headframes and machines including a 1920s Osgood steam shovel and an 1840s-era Cornish walking beam engine. The working blacksmith shop and 10-stamp ore mill are open during special events or by appointment only.
