Abstract

Various drilling programs were successfully carried out this year for a range of outcomes, including updating the resource model, density and yield assumptions. RC drilling will increase the confidence of GEMCO's resource model in order to optimize the long term mine plan. Sufficient data is available from the diamond core drilling programs to apply to the next 5 years of the mine life. Core drilling has therefore been replaced by a more extensive RC infill drilling campaign for the upcoming period. Results of these drilling programs are currently being incorporated into updated models and will be reported during the next cycle. FY17 will focus on additional RC infill drilling in areas of increased complexity. Emphasis will be on the areas outlined in the current 5 year mine plan footprint. In addition, regional drilling is planned for the north and western parts of the mining leases in order to improve confidence and add additional resource in areas of sparse drill coverage. Aerial photography fly-overs will be conducted as required throughout the year in order to calibrate production volumes and for planning purposes.
