methods for ore extraction. The site of the current open pit is Mt Waruwari which is being excavated. The open pit mine moves about 160,000 tonnes of rock material and gold-bearing ore daily, and the underground mine over 2,000 tonnes. Ore is processed in a mainly conventional plant, utilising several SAG and Ball mills, four Autoclaves, floatation cells and CIP / CIL. Gravity recovery is also used, Knelson concentrators doing the primary recovery, with an Acacia Reactor treating the concentrate. A large fleet of Cat 777 and Cat 789 trucks haul on the surface, fed by O&K shovels, and smaller excavators and loaders. A collection of underground development and production drilling equipment break ground, which is bogged by Elphinstone RH series LHD's into a fleet of Elphinstone AD45 trucks. The mine is owned by Barrick Gold, a Canadian mining company. Management and employees The management approach to community relations changed when Barrick Gold took ownership from Placer Dome, which was quickly followed by the termination of the community relations staff that Placer Dome has employed. The change of approach to community relations was described as "more viscous" and "more cruel" by journalist Richard Poplak the Canadaland podcast in 2022. The mine is nominally a joint venture, however, it is managed by Barrick Gold personnel, who are employed on a fly in fly out basis. As of July 2007, all departmental managers are of white extraction and non-PNG origin. None of the management team lives in the Porgera region, and all are accommodated in the mine's camp facilities. The mine has an extensive training and education program, offering diverse traineeships and apprenticeships to locals. This has resulted in many people gaining the necessary skills for employment at the Porgera mine and other mining operations in Papua New Guinea and other countries. In 2009, out of 2,427 employees at the mine, 93.49% were PNG nationals, 1,606 were Porgerans, 33 other Engans, 630 other PNG nationals, and 158 were expatriates. Production The mine was originally one of the world's major low-cost gold producers, but operating costs have increased. In 2004 it produced over one million ounces of gold at a cash cost of US$192 per ounce. Its output fell to about 865,000 ounces in 2005, and has reached 572,595 ounces of gold at cash costs of US$515 per ounce in 2009. With its 2,500 employees and 500 contractors it is one of the
