Lucapa uncovers 63-carat diamond in Angola
The mining company found the Type IIa stone at the Lulo Diamond Concession, an alluvial mining operation.
This 63.05-carat, Type IIa diamond, which was uncovered at the Lulo concession in Angola, is mining company Lucapa’s largest since it started commercial mining operations in January.
Perth, Western Australia--Lucapa Diamond Company recovered an “exceptional” 63.05-carat, Type IIa diamond from its alluvial mining operations at the Lulo Diamond Concession in Angola.
The stone came from mining area 31 at Lulo, north of the diamond processing plant.
Though it is the company’s third-largest stone unearthed at Lulo, behind 131.40-carat and 95.45-carat stones (both of which also were Type IIa) uncovered from the original bulk sampling activities south of the plant, it is the biggest diamond recovered since Lucapa started commercial mining operations at the site in January.
“This exceptional recovery further underlines the potential of the Lulo diamond field to consistently produce large gems of exceptional quality across the whole mining license area,” Lucapa CEO Stephen Wetherall said.
The diamond find comes as Lucapa and its partners ready to start mining at the higher-grade BLK_08 area in Lulo, which is both where the 131-carat stone was found and which saw a sample grade of 95 carats per 100 cubic meters.
The Lulo Diamond Concession is located in the diamond-rich Lunda Norte province in Angola. Lucapa has been undertaking continuous sampling efforts at the mine since 2008, during which it has proven up to two major kimberlite provinces and areas of diamond-rich alluvial gravels.
The company signed a 35-year mining license agreement in November 2014 and began mining in January.
Lucapa, run by managing director Miles Kennedy and former Rio Tinto executive Gordon Gilchrist, operates Lulo as a joint venture with Endiama, the Angolan government’s diamond agency.
