Yes, I did know that (about the scoping study having assumed a gold price of A$2650/oz). The prelim scoping study also includes a sensitivity analysis to reflect net cash flow outcomes on a couple of different price variations for POG, gold recovery, mining costs, process costs, capital costs. You'll find it on page (4) of the scoping study document if you feel inclined to consider the details.

I notice in your post where you mentioned $526.6M (in the context of ADG's JORC resource of 167,700oz) that you didn't mention anything about costs / expenditure involved in producing 169,700 oz. Any particular reason why you decided not to mention anything about costs?

Obviously the 167,700oz resource is only an accumulated estimate of patchy mineralisation in various places within the ADG mining & exploration tenements & isn't worth much unless it's extracted & sold.
