Ann: 32% increase in Tres Amigos Resource, page-4

It was still an additional approx. 35,000t of metal = $100,000,000 in situ value. In reality it's probably worth $AUD150 per additional ore ton at those grades so say $AUD27,000,000. Halve it and halve it again = $6,500,000.

In a well run company it might have given a push. But the issue here is not the resource, it's the board. The fact that an otherwise positive announce had absolutely zero effect on the SP further reinforces the point.
