摘要

The Lihir (also known as Ladolam) Au deposit in Papua New Guinea is a telescoped ore deposit, in which volcanic sector collapse(s) led to superimposition of shallow-level Au-rich epithermal mineralization upon preexisting but genetically related, porphyry-style alteration. This superimposition created a giant 56 Moz Au resource but also created complications for ore processing, specifically with regard to the difficulties in processing the refractory Au-rich pyritic ore.
