Dear Rob, Chief and Columbia

I am still awaiting an intellectual response to my very valid point regarding haulage capacity from the shaft.

Insults only discredit you and cause the reader to think that you are intentionally avoiding the question because you are afraid of the answer.

Now, once again:

How do you pull 80,000 tonnes a year out of a shaft thats only rated at 15,000 tonnes per year?

No insults pleae, just measures analysis and discussion which is what these forums should be about.
