nigel in his 26minute presentation said 1000m left to drill, currently 27500m drilled on the 75th hole. The last two holes have been for met testwork and 3 more to go for met (1000m aligns nicely with this).
The ss mentions strong desire get upgrade the region under the dam to a measured state to verify and refine the total stripping required and stripping ratio. So yes this likely aligns pit design refinements. Pretty invaluable stuff for both Capex and opex
In my opinion, all drill rigs are well and truly decommissioned by now (by a 1 week margin).
