Ladolam Au deposit (Lihir Mine), Lihir Island, New Ireland Province, Papua New Guinea

Latitude & Longitude (WGS84): 3° 7' 36'' South , 152° 37' 56'' East
Latitude & Longitude (decimal): -3.12668,152.63243


A gold mine and the world's largest known low-sulfidation epithermal gold deposit. It is located in an active hydrothermal system.
Ore formation involved an earlier un-economic porphyry stage, and a later, overprinting low sulphidation advanced argillic phase accompanying the bulk of the gold.

Exploration since 1983 has defined several adjacent and partly overlapping deposits: Lienetz, Minifie, Coastal, and Kapit with adjacent satellite deposits of Borefields and Camp. The bulk of the known mineralisation is in Minifie and Lienetz.
