Lucapa Diamond said the next phase of exploration work at Lulo in Angola is set to begin at the “high priority” L259 and the nearby L13/15 kimberlite.
The company operates Lulo in partnership with the Angolan state-owned diamond company, Endiama and Rosas & Petalas.
It said in a statement to shareholders that exploration teams and equipment were being mobilised to Lulo from South Africa to conduct ground-based electromagnetic and gravity geophysical surveys in the next stage of a systematic kimberlite exploration programme.
The programme seeks to locate the sources of the “exceptional” diamonds from the mining block 8 alluvial area, it said.
“The EM and gravity surveys are considered efficient and cost-effective techniques to identify the body and outer rim of the kimberlite structures,” said Lucapa.
“Once this is achieved, the next stage will involve either the surface excavation of and/or drilling for, pyroclastic kimberlite bulk sample to be processed through the 150 tonne per hour diamond plant at Lulo to test for diamonds.”
The geophysical surveys would commence at L259 and continue to the north-east towards the L13 kimberlite.
It said the survey work would also cover the proximal L15 kimberlite on the southern side of the Cachuma River from L13
Meanwhile, Lucapa said results for a micro probing analysis of kimberlite indicator minerals were now expected in two weeks following a delay caused by power outages in South Africa.
