Iron Mountain District

The Iron Mountain District, also known as the Iron Springs District, is a large, high-grade iron deposit[1] in southwestern Utah, near Cedar City. It is currently in care and maintenance status (not actively producing iron ore) by CML Metals Corporation, a division of Palladon Ventures and Luxor Capital. Previous owners include Geneva Steel and U.S. Steel.

The district is made of three primary topographic highs along an approximately 17 mile lineament: Iron Mountain to the southwest, Granite Mountain in the middle, and The Three Peaks in the northwest. Mineralization in this district occurred as rings around the highs as a skarn, a replacement of existing carbonate rock material with high-grade iron ore, mostly in the form of high-grade (>50%Fe in places) magnetite, but also locally hematite. Minor pyrite is also present. Hot fluids are sourced from mid-Tertiary intrusions, which core all three areas.

Major areas of iron deposits and their associated mines/pits/ore bodies include:

  • Iron Mountain
    • Blowout
    • Blackhawk
    • Comstock
    • Mountain Lion
    • Tip Top
    • Pinto
    • Chesapeake
    • Excellsior
    • Homestake
  • Granite Mountain
    • Desert Mound
    • Queen of the West
  • Three Peaks
