cdu likelyup soon in senate inquiry into asic, page-125

zzedzz,

Has it ever occurred to you that CDU might not yet have grade measurements for the stockpiles (note: plural) that they are sufficiently confident of, to publish.

Have you ever considered the difficulties in measuring precise grades of inhomogeneous stockpiles that contain large lumps or masses of material containing the element of interest?

I suspect that determining the grade of a stockpile isn't necessarily an easy task. I would think that the first job would be to reduce the grain size (i.e. crushing) then homogenise each of the stockpiles and finally devise a means of sampling them adequately.

All this would have to take place well before the chem lab comes into play.

Best thing would be for HC posters to hold their silence and let the professionals at Rocklands get on with it.

Cheers, Gung
