A large 133.4 carat diamond has been recovered from Lucapa Diamond’s Lulo deposit.
This rock is the largest recovered from the Lulo mine to date.
It was found in Mining Block 6, a new site only four kilometres from the diamond plant and two kilometres downstream from Lucapa’s Mining Block 8, located in Angloa.
Also found within the first excavations of Mining Block 6 have been three other special diamonds, weighing in at 29.2, 12.37, and 11.1 carats.
Despite the size of the 133.4 carat diamond it is not a high quality rock.
“While the compound 133.4 carat diamond is not of high quality,” Lucapa explained,” the recovery of this large stone and three other specials – any diamonds weighing more than 10.8 carts – together with the precious recovery of six specials from the nearby lower lying BLK_6 and BLK_19 alluvial exploration bulk samples underlines the potential for Mining Block 6 to be another significant source of large alluvial diamonds.”
Lucapa chief Stephen Wetherall said he was delighted over the discovery, adding that Mining Block 6 is also not contained in the company’s recently released JROC resource.
“We are certainly excited by what we are seeing at Mining Block 6 where our management exploration target is to prove up sufficient gravels to incrementally add up to 12 months of alluvial diamond production,” Wetherall said.
“The fact the 133.4 carat stone is a compound diamond which is unlikely to have travelled very far from its primary source – and its relative downstream proximity to Mining Block 8 and our high priority kimberlite targets – we believe is very significant.”
Late last year the world’s second largest single diamond was recovered in Botswana.
The 1111 carat, type IIa, gem was found from the south lobe of Lucara’s Karowe mine.
