TITLE: Tour Three Mines

Most metals we value are dispersed in the rocks of Earth’s crust. Miners look for places where natural processes have concentrated metals into mineral deposits that can be mined economically. In this exhibit, compare three remarkable deposits from different parts of the United States.

  • Sterling Hill Mine
  • Copper Queen Mine
  • Morefield Mine
