Lucapa discovers more diamonds at Brooking project

15 january 2018

Lucapa Diamond Company said it recovered more diamonds at its 80 percent-owned Brooking project, in Western Australia.
The company, which also has stakes in Angola’s Lulo project and Lesotho’s Mothae project, said 119 diamonds, including seven macro-diamonds of up to 1.0mm were recovered from microdiamond analysis of 86.8kg of core sample from the one hole drilled at Little Spring Creek prospect.
Little Spring Creek was located within 50km of the Ellendale diamond mine, which, when in production, produced more than 50 percent of the world’s annual supply of fancy yellow diamonds.
Lucapa said Little Spring Creek results enhanced the prospectivity of the other proximal targets at Brooking where diamonds and indicator minerals were also recovered in previous surface sampling programs.
 “The high concentrations of micro-diamonds and macro-diamonds recovered from the Little Spring Creek drill core sample is extremely encouraging and the counts are very similar to the MIDA results from the Ellendale E9 and E4 diamond pipes 50km west in the West Kimberley lamproite field,” said Lucapa managing director Stephen Wetherall.
Lamproite pipes were a known host of diamonds in the West Kimberley region.
Wetherall said the objective of the drilling programme was to identify lamproitic material from targets identified during earlier surface sampling.
