|Lucapa Diamond Company Limited (Lucapa) has announced the recovery of eight special diamonds (individual diamonds weighing more than 10.8 carats) from trial mining of gravels from the E46 alluvial terraces at the Lulo Diamond Project in Angola.
Among the diamonds recovered from E46 is a 68.1 carat diamond stone classified as a Type IIA D-colour gem. The other "specials" recovered from E46 are reportedly a mixture of gem and boart diamonds weighing 30.5 carats, 25.3 carats, 14.8 carats, 13.8 carats, 12.9 carats, 12.3 carats and 11.5 carats.
The recovery of these large special diamonds from the E46 alluvial terraces is significant, says Lucapa, as the largest individual diamond recovered from the initial exploration bulk sampling phase conducted in that area in 2013 weighed just 6.9 carats.
E46 is located approximately 10km upstream of alluvial Mining Blocks 6 and 8, which have been the source of frequent special diamond recoveries of up to 404 carats.
The company reports that the E46 area has been a recent focus of alluvial mining activities while access to Mining Blocks 8 and 6 have been restricted due to heavy rains during the Angolan wet season. Diamond production from Mining Blocks 8 and 6 is scheduled to be scaled back up to the rate of 20,000 bulk cubic metres per month once the wet season ends in April, as ground conditions permit.
Commenting on the recovery of the large specials at E46, Lucapa Chief Executive Stephen Wetherall says, "The potential of the E46 alluvial terraces was highlighted in the initial bulk sampling and maiden JORC diamond resource published in December 2015. These recent larger special recoveries from trial mining and resource extension work further support that potential."
Continues Wetherall: "Our immediate kimberlite focus is to commence drilling at the high priority targets defined by our systematic geophysical programs over the L259 target and surrounding areas to locate the primary source, or sources, of the exceptional alluvial diamonds being recovered from Mining Blocks 8 and 6.""We look forward to the commencement of this exciting kimberlite drilling program in April and to our ongoing alluvial diamond operations in Mining Blocks 8 and 6 throughout 2016."
