After the update, and having lost lots! are they worth holding on to,any thoughts welcome.

I saw them selling diamonds on the street in Kinshasa. They probably came from alluvial diamonds, in the forests and swamps, scattered over a lot of the East of the country. These alluvial diamonds all came from somewhere, so it's highly likely to be worth looking in the mountainous regions round the East and South of the country.

Kasai (one of GRN's exploration areas) is sort of on the country's Southern border but the Kasai craton extends into Angola and we already know that Petra Diamonds have found many kimberlites in Northern Angola, which implies that there are good prospects for hard rock diamonds in Kasai province in DRC.

One of Petra Diamonds' areas is called Alto Cuilo, which pretty much means the high end (i.e. source) of the Cuilo River. That river flows Northwards into Congo, (where they call it the Kwilu) so one could easily expect alluvial diamonds along that river in Congo. Mind you, that would not be the only river in Congo to have diamonds.

Arf Dysg, Lets hope GRN finds a load,are we the only ones in GRN? comeon you other investers, lets hear from you.
