"We expect to increase our exploration budget at Porgera in 2016 to focus on underground targets which have been identified through a new geological model." The Porgera mine employs more than 2500 PNG residents. Hidden Valley Newcrest Mining has a strong presence in PNG, with the Hidden Valley and Lihir operations. Hidden Valley is an open pit gold and silver mine comprising the Hidden Valley, Kaveroi and Hamata lodes. In the 2015 financial year the mine produced 189,202oz of gold and about 1.78moz of silver. At the end of November Newcrest revealed that the mine was "unprofitable and free cash flow [was] negative in the past financial year". As a result, the company deferred the next open pit waste stripping program. In recent years the Hidden Valley mine has been overshadowed by several fatal incidents. In July 2014 an employee was fatally injured in a road incident, temporarily suspending operations. A fatality was also recorded in December 2014.
