Lucapa Diamond’s stand-alone kimberlite bulk sample plant (“KBSP”) has been fully commissioned and the processing of priority kimberlite bulk samples has commenced.
In February 2020, Lucapa announced highly-encouraging exploration results which have put the focus of the kimberlite search on the high-priority kimberlites and targets in the Canguige catchment area upstream of the Cacuilo River valley. These high priority kimberlites were drilled in preparation for bulk sampling through the Lulo alluvial plant to test for diamonds.
With the concession having a high anomaly to kimberlite conversion rate, kimberlites will be added to the priority sampling list as concurrent discovery drilling and mineral chemistry analysis continues.
“A tremendous amount of exploration work has been completed by the partners on the unique large stone and high-value Lulo concession over the years and these results point to the strong potential for a special primary source discovery on the Lulo concession.
With the commissioning of the kimberlite bulk sample plant completed, the Project Lulo Joint Venture partners can now expedite kimberlite sampling to recover commercial size diamonds and to quickly assess the economic potential of a positive result,” commented Stephen Wetherall Lucapa’s Managing Director.

” In a statement, the Chairman of the Board of ENDIAMA E.P., Dr. Ganga Júnior, said: “It represents another crucial step by ENDIAMA and its partners in consolidating the development strategy for the diamond industry in Angola, particularly concerning primary deposits. Despite being delayed, we are convinced that this action will generate impactful results.”

The company reports that a number of kimberlite bulk samples have already been extracted during the KBSP construction phase and are on the feed pads awaiting treatment through the KBSP. The kimberlite bulk samples will be processed at a rate of approximately two samples every six weeks. On a concession with a high anomaly to kimberlite conversion rate, confirmed kimberlites will be added to the priority sampling list as concurrent discovery drilling and mineral chemistry analysis continues.
