Lucapa identifies 11 new electromagnetic kimberlite exploration targets at Lulo

27 july 2017

Lucapa Diamonds said an extensive 8,566 line km Time Domain Electromagnetic (TDEM) survey at Lulo Mine in Angola has identified 11 new electromagnetic (EM) conductive kimberlite exploration targets of up to 150 hectares with little or no previous magnetic signature.
Lucapa and its partners Endiama and Rosas & Petalas had been conducting a kimberlite exploration programme at Lulo, which seeks to locate the primary hard rock sources of the large and premium value Lulo alluvial diamonds.
The TDEM results had enabled the Lulo geological team to update the ongoing kimberlite drilling programme, said Lucapa.
Of the 11 new targets, five were located along drainage systems feeding into the Mining Block 8 area, which had been a regular source of large and premium-value, irregular shaped and jagged edged alluvial diamonds.
Lucapa said three of the new EM targets were located further south-east along the Cacuilo River near the L165-L170 kimberlite area.
This region, it said, was previously highlighted as an area of exploration interest due to favourable mineral chemistry results, including a micro-diamond and G10 garnets.
Meanwhile, Lucapa said kimberlite drilling at Lulo would continue for the remainder of 2017 with the aim of extracting core from the priority targets identified from the TDEM results.
“This systematic drilling programme will also include a planned deep hole at the L259 target, when ground conditions permit,” it said.
