Title: Modeling the response of the geothermal system at Lihir Island, Papua New Guinea to mine dewatering

Lihir Gold, Ltd., with RTZ Corporation, Niugini Mining Ltd. and the Government of Papua New Guinea as major shareholders, plans to mine two contiguous gold orebodies located in the Luise Caldera, Lihir Island, Papua New Guinea. Niugini Mining Ltd. first discovered the deposit, which is believed to be the largest undeveloped gold deposit in the world, in 1982 and detailed exploration was later conducted by Kennecott Corporation (an RTZ subsidiary) who also prepared the plan for mining the deposit. The gold was deposited in the caldera breccias by rising hot fluids from a still active geothermal system to form the orebody which is to be mined in a 2 km x 1.5 km open pit that will ultimately reach a depth of about 220 m below sea level.
