Massive diamond found in Angola

Australian-based Lucapa and its partners Empresa Nacional de Diamantes E.P. and Rosas and Petalas, are pleased to announce the recovery of a 227 carat diamond from the Lulo Diamond Project in Angola.

Testing on a Yehuda colorimeter has confirmed the 227 carat diamond is a premium-quality Type IIa D-colour gem.

The 227 carat Lulo 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.
  • The biggest diamond recovered to date from the new XRT large-diamond recovery circuit recently installed at Lulo.
  • The 7th +100 carat diamond recovered to date from Lulo.
  • The second biggest diamond recovered in Angola on record behind the 404 carat 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 of which Lucapa is a 40 percent owner and operator.

Significantly, while the 404 carat 4th February Stone and the five other previous +100 carat diamonds were from Mining Blocks 8 and 6, the new discovery was recovered from new Mining Block 28.

Mining Block 28 is located approximately 4km south of Mining Block 8 and a similar distance north of Mining Block 46, providing further evidence that the entire 50km length of the Cacuilo River within the 3,000km2 Lulo concession hosts large, valuable diamonds.

To date, approximately 20 per cent 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 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 Managing Director Stephen Wetherall said he was delighted that after delivering the highest $ 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.
“It is fitting that within a week of the anniversary of recovering Angola’s biggest diamond…we have now recovered Angola’s second biggest diamond on record, our 227 carat Lulo gem.,” said Wetherall.

“Significantly, it also reinforces the game-changing potential of the kimberlite program we are advancing at Lulo, which will soon involve three rigs drilling multiple priority targets in the very areas where we are recovering these large premium-value diamonds.”
