COPPER-GOLD – New Copper Hill estimate
The estimate was prepared by Hellman & Schofield director Dr Phillip Hellman using a 0.2% copper cut-off. The measured, indicated and inferred resource inside the reporting pit is 163 million tonnes @ 0.32% copper and 0.27 grams/tonne gold for 527,000 tonnes of copper and 1.4 million ounces of gold. The resource outside the reporting pit is 34 million tonnes @ 0.27% copper and 0.19 grams/tonne gold for 91,400 tonnes of copper and 200,000 ounces of gold.
At a cut-off grade of 0.5% copper there are 11 million tonnes inside the reporting pit @ 0.67% copper and 0.61 grams/tonne gold for 76,900 tonnes of contained copper and 200,000 ounces of gold while there are 200,000 tonnes outside the pit @ 0.55% copper and 0.41 grams/tonne gold for 1300 tonnes of copper and less than 100,000 ounces of gold. These figures indicate the potential for a start-up pit.
The optimized pit was generated using Whittle software to maximize undiscounted cash flow using US$5.30 per pound of copper and US$2120 per ounce of gold commodity prices and recoveries of 85% for copper and 80% for gold with 45 degree overall pit slopes.
A total of 85,236 metres of drill holes were available for the resource estimate and comprised 61,729 metres of reverse circulation percussion drilling and 23,507 metres of diamond core drilling.
