Lucapa Diamond Company has recovered a 25ct yellow gem diamond from the Mothae kimberlite mine in Lesotho, southern Africa.
The gem quality Special was recovered from the neck zone of the Mothae kimberlite, which is not part of the operation’s JORC resource of more than 1Mct.
Lucapa managing director Stephen Wetherall said the diamond was recovered within the first two days of trial processing through the bulk sampling plant after recent efficiency and security modifications.
“Following sign off of the modifications, Mothae will commence processing three 50,000t bulk samples of kimberlite material from the neck, north and south east zones, with the aim of adding to the JORC resources and the mine life,” Wetherall said.
A 6ct diamond was also recovered during the first two days of trial processing of material from the neck zone.
Meanwhile, construction of a new 150t/hr treatmemnt plant with XRT large diamond recovery technology continues on schedule for commercial production in the second half of 2018, according to Lucapa.
