My concern is that if you increase the size of the digging fleet (extra digger and trucks) then you mining costs goes up. Unless you then send out more product, your unit cost has to rise (at least that is how I see it, unless I am missing something).

I want tty to send out more ships to cover the cost of the third fleet, not do more pre-strip. Pre-strip is good for the long term, but you still need to at least maintain the rate of product going out, and then increase the amount that goes out to cover costs.

All IMO though and am happy to be proven wrong.
