I respect all views, but IMO the diamonds recovered from blocks 6 and 19 came from either L259 and/or upstream of blocks 6 and 19. Prior to the discovery of L259 my thoughts centred on L248 as the source, however they have since tested that kimbo and quickly discounted it.

Unless someone can convince me that the Cacuilo River flowed in the opposite direction at some point, we should assume that the source(s) of alluvial diamonds is either upstream or adjacent to the alluvials. Likewise, the diamonds mined in the many alluvial operations along the Cuango River, all the way to the mighty Congo River, are believed to have come from the Chitamba/Lulo kimberlite cluster, i.e. upstream. Not surprisingly, both of the major rivers on our concession, the Cacuilo and Lulo Rivers, spill into the Cuango River.

L259 = location, location, location!!!
