As I've only started to look into ACB still have penalty to study.
got off HC-from a good poster Tibbs-
The current mining feasibility studies have ALWAYS been based on mining the surface, secondary uranium in the calcrete, & Karoo mudstone. This was based on the JORC of 2008, and the scoping study models have been given the go ahead as feasible. Since then we have had another 12 months of drilling at Mokobaesi, Kraken, and Gorgon. Also they have since discovered and drilled a NEW deposit at Serule, and now another has been hit at Serule West. They still have only touched the surface of the region, with another 80% of Letlhekane yet to be drilled .... they will be drilling here for the next 4 years plus!
Also a comment that the primary ore is too "deep" ... what a load of absolute garbage! ACB's deepest ore is around 60m, with most of the "deeper" ore around 40m ... at Gorgon drilling has regularly intercepted up to FIVE mineralised zones in each drill hole, with mineralisation starting at around 15m. At Mokobaesi, the calcrete ore is at surface, the karoo sediments inder that, and the primary ore under that again .... deep? Rubbish! They will be mining the shallower secondary ores first anyway! The key is the stripping ratio ... which is fine.
