On going exploration success continued to add higher grade inferred mineral resources over the next few years while a large portion was converted to mineral reserves. As of the end of the years, mineral reserves had increased relative.

The main objective of the CGE was to identify the most cost and capital effective approach to mining mineral resources within the main area of focus over four mining horizons and down to a maximum depth 1,000 metres, using existing mine infrastructure. As such, there remains additional opportunities for mine life extension and further expansions incorporating of inferred mineral resources and the significant exploration potential with the deposit open laterally and at depth.
