Right here is the text from the last paragraph of the Newcrest report from 1995
Notice how the report says that 10/15 g/t Au is considered to be "Moderate Grade" and further down it says there would be difficulty locating high grade (+20 g/t Au) at such depths.
Also the last sentence where they recommend that Havieron NOT be forgotten.
Obviously back then they must have had such good deposits that their definitions of High Grade were a lot greater than they would be today.
In summary, at Havieron, the 1991-1992 and 1995 drilling has
suceeded in demonstrating the likely presence of a large gold-enriched
mineralised system, hosting, at least in part, moderate grade (10-15 g/t Au) +
sulphide bearing hydrothermal breccia and vein style mineralisation, albeit
beneath +420m of post-mineralisation cover.Given the igh degree of difficulty
of locating high grade (+20 g/t AU), structurally and lithologically controlled
zones beneath such thick cover, it is recommended that exploration of this
prospect be deferred (but not forgotten!) until other, shallower targets in the
Anketell project area and the broader Telfer District have been tested.
