"If warranted"

Grasping at straws? Now we not only have a mine but whittle pit mining which most everyone has. You move your ore from each pit to a central station. Gee. Hard to figure.

Here is the main problem. We need a mine first. Then we can tell management where to place each pit and where the whittle location should be....

It's not rocket science. It's mining to a central location. We have neither.
