They should provide some resource estimates. Selectively mining a few hundred tonnes of high grade and putting it through the plant doesn’t give any clear picture of what the longer term dilution will be like or no idea if the obtained grades are sustainable.

So far based on several years of evidence I’d say the odds are low on them achieving sustained high grade output.

The maths doesn’t add up either based on drilling or reported widths etc. They’d need to show some realistic volume and grade calculations.
With dilution they’ll be lucky to get more then 10g/t out of that zone - 8*15*1.8*3.0sg= 650 tonnes - hardly a mine maker.
