Between 2006 and 2013, SRK supported studies for this large copper-gold open-pit operation in Papua New Guinea, through geological mapping, hydrogeological testing and rock mass characterisation. The studies include slope and underground design for a geotechnical domain model, cutback design, considering shifts in stability as the mine reaches the final depth and a depressurisation study. SRK completed an investigation of a 5-km drainage tunnel to divert water from the pit floor without expensive pumping, mine scheduling studies and detailed open pit: underground interaction studies using numerical modelling to develop a sub-level cave beneath the current pit.
