Locality type:


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.
