This report summarises exploration activities carried out on MEP51630(Ohui) between 22nd June 2014 and 21st June 2017 by Oceana Gold Ltd in Coromandel. The completed exploration work within the permit includes a desktop review and compilation of historic geochemical, geophysical and drilling data into ArcGIS as well as a programme of field mapping and sampling for spectral analysis. Mapping identified significant hydrothermal alteration in the area supporting potential for the existence of an epithermal Au-Ag system. Future work will include continuation of ongoing soil geochemical sampling, geophysical surveys, 500m of drill testing and future target generation. The results of the geological mapping programme and spectral analysis are presented in this report and associated submitted data includes a collection of GIS files and pdf map interpretations.
