With in-ground resources containing over 421,000 tonnes of copper, 1.2 million ounces of gold and 3.3 million tonnes of sulphur it is a valuable resource for Golden Cross Resources, the Central West community and the state of New South Wales New South Wales, state (1991 pop. 5,164,549), 309,443 sq mi (801,457 sq km), SE Australia. It is bounded on the E by the Pacific Ocean. Sydney is the capital. The other principal urban centers are Newcastle, Wagga Wagga, Lismore, Wollongong, and Broken Hill. . Maximising the return from the existing resource is possible if all sulphides can be floated, roasted and converted into acid soluble copper and free gold within an iron oxide-rich roaster calcine cal·cine v. To heat a substance to a high temperature but below the melting or fusing point, causing loss of moisture, reduction, or oxidation and the decomposition of carbonates and other compounds. . Cathode copper can be produced by Solvent Extraction from the calcine followed by Electro-Winning (SX-EW) with the gold leached by cyanide, recovered by Carbon-in-Leach (CIL) and smelted to gold bullion. Roaster exhaust sulphur dioxide will be captured to produce sulphuric acid for copper leaching with the excess available for sale. The residual iron oxide calcine should find a ready market in the steel making industry. On this basis a complete review of the Copper Hill optimised pits has been undertaken (using cost data supplied by Golden Cross) by Australian Mine Design & Development Pty Ltd (AMDAD) indicating a way forward for the project which delivers an estimated DCF DCF See: Discounted Cash Flows for an operating mine of $360 million, a mine life of almost 20 years producing 335,000 tonnes of copper metal, over 1.1 million ounces of gold bullion and 3 million tonnes of sulphur. Basic parameters used for the selected model were: 85% recoveries for copper, gold and sulphur, US$2.70/lb copper, $US800/oz gold, US$30/tonne sulphur, $US:$A 0.85 and a 10% discount rate. The price/cost assumptions used by AMDAD and Whittle 4X allow a lower cut-off grade (0.15% copper and 0.3g/t gold) to define additional mineable blocks within the existing 0.2% copper cut-off resource. It should be noted that the optimised pit cash flows, like the other projections, are indicative only; the optimised pits include Inferred Resources Copyright : Euclid Infotech Pvt. Ltd.
