A gold mine. Porgera was initially an underground operation, with open-pit mining becoming increasingly important from 1993 onwards. Underground production ceased in 1997 but was resumed in 2002. In 2005, 11% of the mine’s output came from underground, with the remainder sourced from open pits and low-grade ore stockpiles.
It is the second largest mine in Papua New Guinea and is regarded as one of the world's top ten producing gold mines.
Located at the head of the Porgera Valley, in rain forest covered highlands at an altitude of 2,200 to 2,700 m.
Mesothermal(-epithermal) style orebody hosted within thermally metamorphosed sediments of the Cretaceous.
One reference was updated as Roger A mine. It would appear that this is a transliteration error or possibly a reference to Pogera in pigin English that is used widely throughout Papua New Guinea.
