Heron Resources announced results of the Pre-Feasibility Study at its Kalgoorlie Nickel Project (KNP) located in Western Australia. The Study indicates a project producing up to 36,000 tonnes of mixed nickel cobalt hydroxide product via the high pressure acid leach (HPAL) process, with a capital cost of US$1.5 billion and an operating cost of US$4.42 per pound of production based on a 0.75 USD:AUD exchange rate. Vale’s study is based on a project treating 2.5 Mt of beneficiated leach feed ore per annum through a two autoclave leaching circuit over a project life of 34 years.

Vale Inco advised Heron that it would proceed with the KNP project Step 3, involving the completion of a pre-feasibility study by the ened of January 2009. Vale Inco will investigate the application of High Pressure Acid Leach, Heap Leach and Atmospheric Leach to the extraction of nickel from the
laterite ores of the KNP. A complete review of each KNP prospect was undertaken. A compilation of the existing drilling was completed. Ground geophysical Electrical Resistivity Imaging (ERI) surveys were completed to follow-up the work undertaken during Step 2 of the KNP and to expand other prospect areas.
