"The deposit was worked for fluorite by Mr. W.E Clark from 1940 to 1942; shipments totalling 27.2 t of acid-grade fluorite were made. The ore was obtained from several pits and trenches extending over a distance of 180 m along the top of a hill. In 1950 Topspar Fluorite Mines, Limited conducted exploration consisting of an open-cut (3 m by 24 m) and an adit driven 27 m from the south end of the cut on the north side of the hill. A mill was conducted on the site."
