Fluorite was produced for the steel and glassware industries from two deposits within 1 km of Plumbago homestead, 40 km north of Manna Hill. Over 580 t were mined during 1932–36, and 110 t in 1956–58. Veins within metasediments of the Willyama Supergroup are up to 1 m wide and consist of quartz and purple fluorite.
