Lucapa unearths 89 ct yellow diamond from Mothae

02 july 2018
Lucapa Diamond has recovered an 89 carat yellow diamond from its 70 percent-owned Mothae diamond project in Lesotho ahead of commercial production in the second half of the year.
It said the diamond was recovered from the current bulk sampling programme at the mine as construction of the new 150 tonne per hour commercial diamond plant continued on schedule. 
“Having recently recovered a 25 carat yellow diamond from the previously untested neck zone in our bulk sampling program, we are tremendously encouraged that this 89 carat diamond was recovered from the south-east zone, an area of the Mothae kimberlite pipe where there has been very limited historical testing,” said Lucapa chief executive Stephen Wetherall.
“This underlines our belief in Mothae. It also vindicates Lucapa’s decision to commit resources to the additional bulk sampling program as construction of our new 150tph commercial diamond plant continues on schedule for commissioning in the second half of this year.”
Mothae’s bulk sampling programme was designed to expand and improve the current JORC Resource by processing areas of the kimberlite pipe which are either not included in the resource or where Lucapa believes there had been insufficient historical sampling.
