Ann: Boorara Drill Results 158 metres at 1.6 g/t Gold, page-6

I personally can not see much wrong with 158 M x 1.6 g/t while average producing mines have these days gold grades around 1g/t:

and importantly the deposit is still open at depth and potentially "growing" with next drills:
Managing Director Jeff Williams today commented: “The latest drill results have extended mineralisation to a depth of 185m that is still open at depth and a potential strike length of 500m from the north end of the Boorara trial pit to the most southern gold intersection in BORC171."
