The Porgera mine, situated in Enga, distinguishes itself from other sites in Papua New Guinea due to the predominant presence of free gold in its ore components. Unlike other minerals, free gold stands alone and is retrieved in its pure form. Mining experts highlight that this type of gold can be efficiently and energetically recovered in significant quantities using gravity concentration methods. Ezekiel Nori, the Superintendent for open pit mining, emphasizes Porgera's uniqueness compared to Lihir and Ok Tedi: "A substantial portion of our ore comprises free gold, which positions our mills strategically. Porgera's gold exists both as free and refractory forms. About 20 percent of our recovery is attributed to free gold, with the remaining constituting approximately 80 percent or less. Anything unrecoverable in the safe mill area undergoes further processing downstream through the pipeline." Nori elaborates on the mine's restart process: "Resuming operations entails rock drilling using our existing rigs, enhancing our comprehension of the subterranean ore. Presently, work has commenced on the mine's western wing, where excavators are clearing accumulated mud from the three-year closure period."
