Diamond-bearing lamproite discovered!

Lamproite of macro and micro-diamonds

discovered at Ellendale diamond mine!

Near-surface lamproite intersected in drilling at the Little Spring Creek prospect at Lucapa’s 80% owned Brooking diamond project in the West Kimberley & 119 diamonds, including 7 macro-diamonds of up to 1.0mm, recovered from microdiamond analysis of 86.8kg of core sample from the one hole drilled at Little Spring Creek.

Discovery of diamond-bearing lamproite validates results from previous surface sampling programs at Little Spring Creek, where 24 diamonds and highly-anomalous concentrations of lamproite indicator minerals were recovered. Little Spring Creek located within 50km of the Ellendale diamond mine, which, when in production, produced more than 50% of the world’s annual supply of fancy yellow diamonds!

Lucapa Managing Director Stephen Wetherall said he was delighted with such spectacular results from

the Brooking drilling program. H e expressed, “The main goal of our drilling program at Brooking was to identify lamproitic material, which could be the primary source of the diamonds and indicator minerals recovered from the earlier 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.

We now look forward to follow-up work programs at Little Spring Creek to identify the extent of the

diamondiferous lamproite body and to further assess its diamond content when conditions permit.”
