    K92 Mining owns the Kainantu Gold Mine located in the Eastern Highlands province of Papua New Guinea. The Kainantu Gold Mine is a high-grade, low cost underground mine within a ~725 km 2 land package in a region known for Tier 1 deposits. K92 has doubled throughput to 400,000 tonnes/year, which would increase annual production to +120 koz/year.

  • Extracting Gold

    To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.
