Ann: Assays infer mineralisation potential at Broken Hill, page-15

I think I know why we haven't seen the 3d model of the DHEM yet. The conversation would have gone like this:
GEO1; "I've got those readings, but the machine doesn't seem to read that high"
GEO2: You're right. Hmm, it only reads up to 2000 siemens. Better send it it away to get recalibrated. If we publish these readings, we will be accused of manipulation.
GEO1; I think we need a reader with a higher range.
GEO2: yeah, the shareholders will just have to wait until it arrives.

So that is what I think, cos it shouldn't take long to get a 3d model.
