Stellar recovers 970 diamonds from Guinea kimberlite project

Stellar Diamonds said it recovered 970 diamonds from 199kg of kimberlite material from drilling and bulk sampling conducted on the Katcha kimberlite dyke, which forms part of the Droujba kimberlite project in Guinea.
It said in a statement emailed to Rough&Polished that 20 diamonds of commercial size greater than 0.85mm were also recovered.
“The abundance of micro and macro diamonds in drill and bulk samples submitted and particularly the presence of 20 diamonds in the commercial size fractions confirm that the Katcha kimberlite dyke has the potential to be significantly diamondiferous at depth,” said company chief executive Karl Smithson.
“We recently announced a highly encouraging surface bulk sample grade of 161cpht from Katcha and these microdiamond results will be used to model the continuity of grade with depth of the kimberlite.”
He said the high grade and considerable 5km strike length of the Katcha dyke demonstrated its potential to add significantly to the already defined 2.5 million carat resource base from the adjacent Droujba kimberlite pipe.
