This looks to contain a lot more detail than the previous announcement.

The Lulo gravel model was interesting - I didn't realise the distribution of diamond bearing gravels throughout the various mining blocks looked like that - I suppose I had assumed it was more consistent. I assume the absence of 'red' (gravel model outline) in mining blocks that are included in the Lulo alluvial resource update means that the diamond bearing gravels do not extend beyond the areas identified? Or could it be that those areas have not been completely tested?

Surely where there are greater concentrations of diamond bearing gravels, that is an indicator of proximity to the source kimberlite(s)? Mining Block 41 as an example looks like it contains a relatively high concentration / volume of diamond bearing gravel - compared to some other mining blocks.

Mining Block 212 on the other hand which is large by size, doesn't seem to contain much in the way of diamond bearing gravels.

I have zero expertise and very little geological knowledge. Any more learned views or opinions on this?
