Lucapa begins new exploration programme at Brooking project
It said the latest exploration programme was designed to follow up on the micro- and macro-diamond counts recovered from the first two holes drilled at the Little Spring Creek diamond discovery.
Lucapa said the follow-up Brooking exploration programme comprised of bulk sampling of the Little Spring Creek lamproitic body to test commercial macro-diamond population, value and grade.
There would also be a drilling of new lamproite targets defined within the broader Brooking project and re-assessment of the known Big Spring Creek lamproite.
Lucapa said results of the Little Spring Creek bulk sampling programme and the Brooking drilling programme would determine the scope and scale of follow-up work at the project.
Meanwhile, the company said it was also planning to selectively drill and collect surface and outcropping samples at the known Big Spring Creek cluster of lamproites in the north-east of the Brooking project.
These were discovered by CRA Exploration in the 1970s.
“This drilling and surface sampling aims to recover material which will be used to re-assess the lamproite bodies for diamond potential,” it said.
