The South zone of Iceberg is the most sparsely tested of all the known mineralized zones along the 3 km strike length of the Iceberg deposit. Drilling by NuLegacy shows that gold mineralization is developed in the volcanic rocks and jasperoid alteration is developed in the underlying Devonian sedimentary rocks, which may indicate the potential for a large Carlin-type system at depth.
The South zone of the Iceberg gold deposit straddles the north-northwest trending, west dipping Iceberg Fault with ~40-80 meters of mafic volcanic flows overlying ~50 m of Tertiary sediments, tuffaceous volcaniclastics, and conglomerates. The Paleozoic section here is comprised of silty carbonates of the upper to middle Wenban Formation. To date, gold mineralization has only been discovered in volcanic horizons, though the Devonian section has significant jasperoid development, and both the volcanics and underlying sediments are strongly oxidized.
