Block -J QuestionsThanks loparn for the insights. I am new to diamond mining and doing my research on them. I have some questions, anyone knowledgeable in this BB please respond. I don't hold any positions in AFA, so no bashing no pumping intended, just doing my DD.
I was looking at the diamond consessions map and it appears that the leases that are right west to the river mouths bear the most carats, compared to the leases in between, roughly though. Is that the usual case? Does anyone have any knowledge to confirm this?
My take is, being offshore in the middle of Tchauchab and Koichab river mouths which are roughly 125 kms apart the Block J may have held the divider of the river basins and was an elevated area. If that was the case, the diamonds would have migrated down towards the rivers, right? If either of the rivers ran through Block J in the hey days, then it is a totally different scenario. I wish they have provided N-S X-Section of Block J.

Does anyone have info on the depths of the Block J as well as Namibian Gemstones Leases? The company websites says for Block J it is "70 to roughly 170 meters" but how much of the area is in what range is not known.
Also what is "gem-grade" diamonds? I know when, they're are cut and polished, they are very expensive. That I can tell from experience.
