Wonder how the Nabanga internal study is going?
Bit worried about the met work, but will see soon enough I suppose.
Interestingly underground might not be too expensive.
Oz costs are apparently about $8-10k/m for declines and $4-5k/m for drives.
So a 2300m drive would cost about $9.2M. Not sure on the BK "discount" - maybe 25% less than Oz, so $6.9M
