Stellar Diamonds plc. (LSE:STEL) announced an update on the initial results of the bulk sampling programme at the Droujba kimberlite pipe in Guinea.
As quoted in the press release:
Processing of the first sample (DBS-5), weighing 244.48 dry tonnes, yielded 171.20 carats for a grade of 69.98cpht, which is consistent with the established average diluted grade for the pipe. However, initial processing of the second sample DBS-06 yielded 151.30 carats from the first 138.06 tonnes processed for a diluted grade of 109.59cpht. The higher grade of DBS-6 could be a function of less internal country rock dilution. The average grade from all sampling to date is now 76.20cpht, slightly higher than reported in the resource statement.
Stellar’s Chief Executive, Karl Smithson said:
We continue to make strong progress as we advance the Droujba pipe through the bulk sampling stage. The early results from the first phase-2 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.
