Lucapa Diamond is steaming ahead with its search for the hard-rock origin of the high-value alluvial diamonds being mined at its 40%-owned Lulo project, in Angola.
Lucapa and its partners, Endiama and Rosas & Petalas, believe they may be able to find the upstream source of the diamonds and mine them directly.

They commenced a drilling programme in the Canguige catchment area targeting five kimberlite pipes considered prospective to host diamonds, along with two additional priority anomalies.
Lucapa is convinced that there is a high probability that the Canguige catchment is the source of the precious gems.
A sample taken from the Canguige stream yielded 45 diamonds, which comprised of rare Type IIa gems and top D-colours as well as a light fancy yellow.
These diamond recoveries confirmed the Canguige catchment area contains at least one diamond-bearing kimberlite pipe contributing to the alluvial diamonds eroded downstream into the Cacuilo River valley.
