A Pb-Zn-Cu-Ag-Au mine located atop Mt Read, 6 miles (10km) South of Rosebery. The ore is similar to Rosebery (massive, pyrite-rich sulphide ore), but is more metamorphosed and deformed. Mining was mostly between 1894-1986, but there has been some small scale mining at times since. Rehabilitation works began in 2004/2005, though there has been some localised mining since. There are small exposures of the sulphides and gossan in open cuts and adits at the summit.
