Where to Find Magnetite in Utah

Utah magnetite is concentrated in the Iron Springs district in Iron County, where bedded and replacement magnetite-hematite bodies sit in altered Jurassic limestone. The Comstock-Mountain Lion, Desert Mound, and Iron Mountain mines produced massive magnetite ore, and the surrounding outcrops still yield dense, strongly magnetic specimens. Smaller showings at Mount Nebo in Juab County and the Calf Canyon area near Park City add skarn-hosted magnetite octahedra. Beach magnetite (titanomagnetite) concentrates along the Great Salt Lake's south shore. Most Utah magnetite is massive rather than crystalline, and a strong magnet is enough to confirm a specimen in the field.

Standout magnetite spots in Utah

Hand-picked from the full list below, with the reason each one earns a trip.

Spor Mountain
Juab County County
Spor Mountain stands out because its topaz-rhyolite-related deposits made it the world's premier beryllium district and Utah's largest fluorite producer. Mindat documents bertrandite, fluorite, chalcedony, opal, carnotite, hematite, magnetite, pyrite, quartz, and topaz across the district, which makes it more than a single-specimen stop.
