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.
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.
Hot fluids are sourced from mid-Tertiary intrusions, which core all three areas.
Magnetite and hematite occur as replacements in the Jurassic limestone around three Laramide orogeny, quartz monzonite porphyry, laccolith intrusions.
