    wgnhs.wisc.edu/minerals/ferristrunzite Description: Ferristrunzite is a rare phosphate mineral formed by the alteration of other phosphates. RUSK COUNTY: Ferristrunzite is found as bright yellow acicular crystals arranged in radial clusters in vugs and seams in massive cuprite/goethite with quartz at the Flambeau Mine, near Ladysmith. Verified by EDS and X-Ray analysis.
