Spot on. Ground conditions can allow for near vertical faces all the way to 45 degree angles needed from the lowest point to avoid undermining (ha).

It's not going to look good for environmental considerations to have a giant hole in the ground that can nearly be seen from space, the size of ten football fields to dig that far down.

I'd also be quite uncomfortable working in that hole even if I'd engineered it in an area where significant rain events can occur.

The Okvau crusher can plow through something like 6000t a day, it's not a huge one but that's not insignificant. I would expect a big upgrade needed to process bulk overburden.

Buuuuut, as you said, if that higher ground is producing at a good rate it's really just extending the lifetime of the mine. Extending the contract.
