Least the company did optimised the BFS as well from the initial release in Feb, 6.5 - 8.3 billion rand down to 5 - 7.5 billion, thats a fair feat considering how much the rand has strengthened against the USD
Answering your last question to GeoNeo, back in Feb the basket price was approximately $1200 with the merensky reef @ $1239 and the UG2 reef @ $1184, current basket price is $1320, unsure if thats a average.
Talking to a friend that has 20+ years sinks shafts and declines for a living and showed him both options, his impression was once they got to the lower level of the merensky reef they could start developing the shaft to extented down to the UG2 reef with very little disruption to production, liked what he saw with a shallow dip angle from a miners prospective too
