The linear distance between BLK_14 and BLK_20 is 14km, so we can safely theorise that the average of $A6,960 per carat is a fair representation of the return we'd expect to see for alluvial diamonds within the northern section which covers the lower 1/3rd of the Cacuilo valley.

Unfortunately, that area has been extensively worked by garimpeiros, so no records have been tabled with the mines department. They came in their thousands, picks and shovels slung over their shoulders and literally picked the eyes out of that portion of the concession, yet we are still discovering rare and valuable gems.

That said, at this stage LOM hasn't carried out sufficient exploration upstream of BLK_14 where it could accurately apply both a grading and value of the diamonds. That area represents the old river terraces which has been virtually untouched by the garimpeiros. What management is hoping for in the upper 2/3rd of the Cacuilo valley is a similar grade and quality of the stones discovered at BLK_14, which as we know was the site of our first and only pink diamond.

The other, and untouched, side to the alluvial diamonds are the numerous potholes along the odd 50km length of the Cacuilo River. There is no reference to that side of exploration/mining, however, it is included (geographically) within the current boundaries of the MLA.
