Misima Island forms part of the Louisiade Archipelago which is a continuation of the Papuan Fold Belt of the Papuan Peninsula offshore eastwards through the Papuan Plateau. The Misima Gold Project comprises two main deposits, Umuna and Ewatinona, and multiple reconnaissance exploration targets along and adjacent to the 10km strike length of the Umuna Fault Corridor that hosts the historical Umuna deposit, and Quartz Mountain area that hosts the Ewatinona deposit.Mineralisation deposit style on Misima Island is best described as low sulphidation carbonate base-metal epithermal. Mineralisation is strongly controlled by pre-existing structures that have been reactivated and mineralised over time.The Umuna deposit is a complex fault array with a large SE-NW striking fault zone hosting the majority of the precious metal mineralisation, with numerous ancillary splays developed in the footwall east of the main structure. Internal structures within the fault complex and the intersection of structures and splays with the dominant Umuna Fault, are loci for zones of welldeveloped mineralisation.The Ewatinona deposit is dominated by brecciated porphyry units which are cut by steeply dipping faults trending northwest, west northwest and southwest. Mineralised structures can range from crackle brecciated porphyry with base metal sulphide and quartz-carbonate-base metal sulphide infill, to more well-defined fault breccia with stockwork veining and crackle brecciation haloes.
