The Hidden Valley mine is located in Morobe Province, Papua New Guinea, around 300km north-west of Port Moresby, and is part of the 50:50 joint venture between Harmony and Newcrest Mining Limited. The mine, which has a significant gold and silver reserve, was commissioned during the year and had its first gold pour in June 2009. Ore mined was stockpiled ahead of the full commissioning of the carbon-in-leach gold and silver processing plant in FY10. The plant treats 4.6 million tonnes of ore per year and the Hidden Valley Mine will produce on average +250,000 ounces of gold per year and 4 million ounces of silver per year.
