Lucapa makes progress in Botswana

10 january 2017
Lucapa Diamond has completed a preliminary exploration programme at its Orapa Area F project in Botswana, which included ground magnetic, EM and gravity surveys, along with EM soundings and MMI soil geochemical analysis.
The programme was said to have been “successful” in defining a doubled-lobed coincident gravity/magnetic feature at AN01, which would be the priority focus of the next drilling stage.
“This well-defined magnetic anomaly measures approximately 350 metres x 150 metres and represents a priority drilling target within the prolific Orapa diamond field,” it said in a statement Monday.
“While validating the techniques used to define AN01, modeling of the work undertaken at the two known kimberlites at Orapa Area F suggests BK14 is a conventional pipe with no previously-unexplored kimberlite offshoots and that BK38 is a likely narrow dyke.”
Meanwhile, Lucapa said drilling programmes would commence this year in Orapa Area F targets as kimberlite drilling was also stepped up at the flagship Lulo diamond project in Angola.
