Lulo set to commence the pipe at Canguige catchment
Lucapa Diamond Company Limited and its Project Lulo partners update progress on the search for the kimberlite sources of the high-value alluvial diamonds at the Lulo project in Angola. As set out in the ASX announcements, the Canguige catchment has become the focus of the Lulo kimberlite exploration program following the recovery of 45 diamonds of up to 3.75 carats in individual size from stream samples taken from the tributary flowing into the Cacuilo River.
The Canguige catchment hosts five of the 16 Lulo kimberlite pipes rated in a 2019 technical review as being the most prospective to host diamonds, and thus considered potential sources of the high population of rare Type II alluvial diamonds being mined downstream along the Cacuilo River. A delineation drilling program is underway to define the size and structure of each of these five priority pipes in preparation for bulk sampling to test for diamonds.
Further to the ASX announcements, the mobile Hanjin drilling rig has now moved to the third of those five priority kimberlites - L71 – following the completion of delineation drilling at L28 and L30 (Figure 1), where the targeted volcaniclastic kimberlite material suitable for bulk sampling was intersected.
Significantly, L71 is located just ~3km from the main road which runs through the 3,000km2 Lulo concession. The close proximity of L71 to the main road should enable a bulk sample to be excavated from this kimberlite pipe once the delineation drilling identifies the targeted near-surface volcaniclastic kimberlite material.
Two other priority anomalies in the Canguige catchment highlighted in the 2019 technical review are also being drilled in the current program to confirm if they are kimberlites.
