Site: Hidden Valley Mine
Location: Morobe Province PNG
System: 2 instrument
Commissioned: 2014

Hidden Valley is located in the highly prospective Morobe province in Papua New Guinea, approximately 300 kilometres north-west of the nation’s capital, Port Moresby, and 90 kilometres south-west of the sea port of Lae.

The operation is owned by the Hidden Valley Joint Venture (HVJV), one of three unincorporated joint ventures between subsidiaries of Newcrest (50 per cent) and Harmony Gold Mining Company Limited of South Africa (50 per cent), formed in 2008 and referred to collectively as the Morobe Mining Joint Ventures (MMJV).

Hidden Valley is an open pit gold and silver mine, consisting of three main lodes – Hidden Valley, Kaveroi and Hamata. Gold and silver doré produced at Hidden Valley is transported to the Perth Mint in Australia to be refined.

Construction of the Hidden Valley mine began in 2007 and commercial production commenced in September 2010.  The joint venture is continuing to ramp up operations to target annual production of 250,000 ounces of gold and 2.5 to 3 million ounces of silver (100 per cent basis).

For the financial year ending 30 June 2013, the site produced 170,008 ounces of gold and 1,712,656 ounces of silver (100 per cent basis).
