Where to Find Pyrite in Missouri

Missouri pyrite comes mostly from the Tri-State and Old Lead Belt districts, where it accompanies the galena-sphalerite ores that made the state the largest lead producer in U.S. history. The Picher field crosses the Oklahoma line into Jasper and Newton counties, and the dumps and chat piles around Joplin still carry pyrite crystallized in dolomite vugs, often as bright, undamaged cubes alongside sphalerite. The Old Lead Belt around Bonne Terre and Flat River in St. Francois County produces pyrite as crusts on dolomite and limestone, with the Buick and Brushy Creek mines (Viburnum Trend) adding larger crystals. Cube faces tend to be striated and golden, with minimal tarnish underground. The most productive ground is in Joplin chat piles (Jasper County), Buick and Brushy Creek mines, Viburnum Trend (Iron County), Bonne Terre and Flat River (St. Francois County).

Casual hand collection of common rocks and minerals like pyrite is allowed on most BLM and U.S. Forest Service land in Missouri, with daily and annual limits set by the local field office. National parks, most state parks, and tribal land are off-limits. Always confirm rules before a trip.

Joplin chat piles (Jasper County) is the standout. Other strong ground includes Buick and Brushy Creek mines, Viburnum Trend (Iron County), Bonne Terre and Flat River (St. Francois County).
