RAPAPORT... Stellar Diamonds continues to advance the second bulk sampling phase of its Droujba kimberlite pipe in Guinea. The company processed 2,023 dry tonnes of ore recently from eight pits and returned grades of 70 carats per hundred tonnes (cpht) from a first sample and 109 cpht from a second.
The largest gem-quality diamond was 6.90 carats, while there were other stones of 9.55, 7.68, 5.55, 4.25 and 4 carats.
Stellar's chief executive, Karl Smithson, said, "The early results from the first phase-two samples processed are very encouraging, with high-grades and the presence of larger gem-quality diamonds than have previously been recovered from the earlier bulk sampling.
“Furthermore, the recovery of large stones up to 9.55 carats from the small volume of kimberlite processed is indicative that Droujba may have a coarse stone size distribution. Once the processing has been completed the diamond parcel will be exported to Antwerp for valuation and upgrading of the independent resource model.''
