SUDEST ISLAND Potential large-scale porphyry copper-gold targets in historic gold mining area.
The Sudest Island Copper-Gold Project comprises one EL that covers 315 km2 Sudest Island, including historic small scale hard rock and alluvial mining areas. Sudest Island was the first hard-rock gold location identified in PNG. Historically approximately 15,000 ounces gold has been produced from alluvial mining. The island is located 100km SE of the Misima Deposit, which historically produced approximately 3.7 million ounces of gold and 18 million ounces of silver.
AMD considers the project to be highly prospective for porphyry Cu-Au and high-grade vein style mineralisation due to the presence of numerous gold anomalous drainages, historical alluvial gold mining and favourable intrusive activity on the Island.
Past exploration has defined a large number of auriferous anomalous drainages distributed across the island. Systematic follow up of these anomalous drainages has been limited. The presence of intrusive rocks with compositions typical of those associated with large mineralised porphyry systems have also been identified on the island. Despite these positive features, no drilling has previously been undertaken on the Island.
AMD has recently completed an island-wide aeromagnetic program (late 2018) to locate potential porphyry-style copper-gold mineralisation associated with post-metamorphic intrusives and regional drainage gold geochemical anomalies. Processing and interpretation of data will be completed in late 2019 with ground follow up of both porphyry Cu-Au targets defined by the magnetics survey and high-grade gold vein style targets to commence in 2020.
