RE: Marsfontein was only 0.4 Ha but had a payback of 3.5 days20 Apr 2021 16:08
I do not believe we are looking at a large kimberlite of over 1 HA to make it economical to mine. Marsfontein was only 0.4 HA very moderate in size. I also think the in ground value posted in JC answer references the finding of the small diamonds in the drill sample. Which were a surprise to find in such a small sample. True value of in ground diamonds can only be extrapolated when a larger sample is studied.
However, I feel we could be sitting on a significant find and only time will tell how large it is.
