Heres a question for some more knowledgeable than I,reference to the Arruwurra,is the drill spacing of 500m x 500m acceptable for estimated an inferred resource?.
Bearing in mind,rum used 400m and 200m spacing?
Its obvious at least to me whats going on here both in terms of phosphate tonnage and resource deliniation.
I know whose figures I'd rely on.
