Significant exploration targets identified at Lulo

Apr 15, 2024

Lulo roughLucapa Diamond Identified three sites across Angola, Botswana and Western Australia. Lulo Kimberlite Exploration, Angola (Project Lulo Joint Venture – Lucapa 39%, Endiama 51% and Rosas & Petalas 10%).

The Project Lulo JV is conducting exploration to locate the source of the high value diamonds that are being recovered from the Cacuilo River valley by the SML mining operation.

To date over 560 geophysical anomalies potentially related to kimberlite pipes have been identified, with 164 drilled and 141 kimberlites confirmed. Of the kimberlites identified, 15 were selected for bulk sampling through a dedicated kimberlite bulk sampling plant (KBSP) which commenced in September 2022 with a further 6 kimberlites added to the selection up to the end of 2023.

To date, 18 kimberlites have been sampled, with 35 samples taken and processed. Nine kimberlites have been shown to be diamondiferous with the most significant diamond recoveries from L164 where 110.66 carats were recovered, including two +10.8 carat special stones, the largest of which was 15.27 carats.

The majority of kimberlites sampled so far have indicated to be very low grade or barren. This is positive in the sense that it supports the hypothesis that the diamonds in the alluvial deposits of the Cacuilo River are likely to be sourced from relatively few, higher grade and significantly sized deposits rather than spread evenly through many small lower grade deposits. This increases the possibility of finding kimberlites with economic potential within the Lulo cluster.
