Ann: Drilling at Mt Aubrey Confirms Epithermal Gold System, page-14

the fact that they had to list one intercept with less than 1g/t as highlight says all. Such low grades would be acceptable if they are over huge widths but over 28m is very average at best.
For example 28m at 0.92g/t with highlight of 16m at 1.2g/t means 16m of 1.2g/t with 12m of 0.55g/t. If we assume 0.5g/t cut off then there is not much to mine outside 16m of 1.2g/t.
Unless there is nearby higher deposit to mine and this lower grade can be blended for volumes and that makes it average at best. And I am being generous here.
Either way, in my view, it is not great result.
