RE:Why is Marble Good?
This is very good summary of the status of the discovery to date.
However, you are grossly exaggerating when you imply that all of the non-graphitised material is pure white marble.
If you look at the NI43-101 report issued in 2014, you will see that most of the marble encountered in those drill holes was described as "silicated marble", and is probably only good for cheap aggregate. transportation costs would preclude selling that material outside of a short radius from the quarry. Also, there is a lot of material which is neither marble nor graphite.
The last news realease mentions findings of fairly large lengths of white marble, but does not make any mention of finding graphite.
If the white marble and the graphite are not in compatible locations, then the whole concept of mining them together to reduce the strip ratio is thrown into question.
It will likely be at least a year, maybe two, before we are able to evaluate this deposit. There is lot of drilling and assaying to be done.
