ASX-listed Lucapa Diamond Company and its partners Endiama and Rosas & Petalas have announced the recovery of a 227-carat diamond from the Lulo diamond project in Angola. Testing on a Yehuda colorimeter has confirmed the diamond is a premium-quality Type IIa D-colour gem.

The diamond is the second largest diamond recovered to date at Lulo behind the record 404-carat 4th February Stone recovered a year ago – also during the Angolan wet season. It is the 7th plus 100 carat diamond recovered to date from Lulo and the second biggest diamond recovered in Angola on record behind the 4th February Stone, eclipsing the 217-carat Angola Star recovered in 2007 from the Luarica mine.

The diamond was recovered by Lulo alluvial mining company Sociedade Mineira Do Lulo (Lucapa 40 % owner and operator).

Significantly, while the 4th February Stone and the five other previous plus 100 carat Lulo diamonds were from Mining Blocks 8 and 6, the 227-carat diamond was recovered from new Mining Block 28. This is located approximately 4 km south of Mining Block 8 and a similar distance north of Mining Block 46, providing further evidence that the entire approximately 50 km length of the Cacuilo River within the 3 000 km2 Lulo concession hosts large, valuable diamonds.

To date, approximately 20 % of this area has been sampled by Lucapa and its partners.

The 227 carat diamond is also the largest stone recovered from the new XRT large-diamond recovery circuit which was successfully installed and commissioned at Lulo during the December 2016 quarter. While the 227-carat stone is yet to be valued by experts, it is expected to be worth in excess of the cost of the XRT unit.

Lucapa MD Stephen Wetherall said he was delighted that after delivering the highest dollar per carat prices from run of mine diamond production in the world in 2016, Lulo had continued to demonstrate its ability to produce world-class diamonds.

“We look forward to the remainder of 2017 with great excitement as we continue to advance our kimberlite drilling and alluvial mining operations at Lulo, while furthering our planning for the development of the Mothae kimberlite project in Lesotho, which, like Lulo, has also produced large premium-value diamonds.”
