THE Sulphide Corporation's works for the smelting of ores containing lead, gold, and silver are situated close to the Cockle Creek railway station, on the main Northern railway line, and are about 95 miles from Sydney and 10 miles from Newcastle. A branch line runs to the works, and siding accommodation and bins are provided for expeditiously handling all ores sent for treatment. The Corporation also possesses wharfage facilities at the port of Newcastle, where consignments of ores arriving by sea can be handled direct into railway trucks for conveyance to the works.The greater portion of the ore treated at Cockle Creek comes from the Corporation's mine at Broken Hill, but a large quantity of other grades is also purchased and treated.
