The Porgera operation comprises Open Pit and Underground mining operations.

Since the first gold pour in 1990, more than 143 million tonnes of ore has been mined in both the Open Pit and the Underground, producing over 20 million ounces in gold production to date. Crusher feed from the mining operations is based on blending the highest gold grades available to maximize the gold output, combined with an additional constraint of sulphur content as required by the Process Plant.

Electricity to the mine is supplied by the Porgera Joint Venture (PJV) Hides Power Station located in the neighboring Hela Province. The gas-powered facility provides 75 megawatts of electricity across a 75 kilometer electrical transmission line to the Porgera Mine site.

A lime plant, 7km away from the mine site provides lime for neutralization. Water is supplied from a reservoir at Waile Creek containing 7 million cubic meters of water.

The Porgera Gold Mine in Enga Province, Papua New Guinea, is owned by the Porgera Joint Venture (PJV).

It is operated by Barrick (Niugini) Limited (“BNL”) which owns 95 percent participating interest in PJV. The remaining 5% is owned by Mineral Resources Enga (MRE) Limited.
