If it were just a matter of what "indicated" resource there is, then it would be a simple matter.
But if you consider that the scoping study is targeting DSO, clearly not all of the 30mt inferred is in this category.
Where cut off of AL/SI Rx may be relevant.
so i would take a view, that they first off need to explain that 55/t is for what grade of their resource as DSO, and i would imagine how much of their resource is both upgraded to indicated, as well as of suitable grade for the SS.
And before anyone says that DSO must be this or that. I am referring to what they have identified at 55/t, which i suspect is their 30/3% type ore, and supplied in a offtake contract agreement, not into any seagulls at the pier.
(DSO Grade is not just head grade of AL, it is also relevant ratio of AL/SI rx)
A few MT of this sub-resource would be a good start of the 800ktpa operation.
