Volcanic-hydrothermal breccias at the Lihir alkalic gold deposit, Papua New Guinea

The Lihir gold deposit contains seven, large, composite volcanic-hydrothermal breccia bodies that are intimately associated with deposit-scale structures. There is a strong spatial relationship between the margins of the volcanic-hydrothermal breccia bodies and epithermal mineralization in Coastal and Kapit ore zones and the Kapit NE prospect. The volcanic-hydrothermal breccias have a late-mineralization timing.
