Ann: Company Presentation, page-6

You see how Yappsu is offset.
They've given themselves the option of a decline out of the bottom of the pit.

Separately, WRT going for it all, if the plant is rated for 10m tpy. On a 3:1 strip ratio they'll can process 400M T over the 10 yrs. I pretty sure a plant designed by GR Engineering (their shareholder) with do 20% above that. Assuming the metal price is there they'll go for it.
What's more is they can always add a ball mill somewhere along the line. There's heaps of optionality.

I see out OZL's announcement today CZI have hired their chief mining engineer. I hope they start rolling out some of his ideas to us ( or I'll may go blue form holding my breath).

Thanks for the update I'll try to digest all of it.
