I’ve always wondered what they might find if they allowed serious mining? People have been finding diamonds in that over worked piece of ground for decades. Imagine what could be found if they started removing and processing overburden and got down to the meat of the pipe?
As indicated in the article, it was commercially mined for decades ... unsuccessfully.
I’ve been there twice in the 70s and didn’t find anything. One thing I’ve noticed is the past several years they’ve been finding bigger diamonds that has come to the surface there. It’s best to go there after its rained. They’re easy to spot.
