The gossan outcrops of the pyritic tin-bearing ore bodies were not recognised as the source of the detrital tin for some years. During the construction of the Emu Bay Railway in 1900, the railway line necessitated a large cutting on the Renison Bell lease, and exposed the main lode system. Capital was not available for development of the property, and operations were confined to the erection of batteries to treat the detrital matter and oxidised ores which were free-milling. Spasmodic attempts have been made to treat the sulphide ore by precalcination and gravity concentration, and at the present time Renison Associated Tin Fines N.L. are experimenting with the flotation of cassiterite, which is preceded by flotation of the iron sulphides. Inspection of all workings reveal that the area has been carefully searched for all outcropping tin lodes, and mining operations have been more or less confined to selective mining of the oxidised ore and very little of the richer sulphide ore.
