Lucapa Diamond Company has announced the successful conclusion of its electromagnetic and gravity survey programme which has helped it to define the target areas for its upcoming drilling programme at the high priority L259. The surveys and analysis of the results were designed by GRS Consulting from South Africa. Field survey work was carried out by GPR Geophysics, Botswana.

Additional surveys were also carried out on kimberlite L13 and L15, and kimberlite target E217, as well as over the known kimberlite L251 to aid in the interpretation of data.

According to the report, “the survey work over L259 had defined an estimated 78-108ha, low-density, moderately-conductive body, modelled to a depth of between 35-100 mget eters. This was consistent with the weathered near-surface expression of a kimberlite, or its crater. The area below the low-density zone was interpreted to have a similar density to the country rock. The rock type below the low density zone cannot be ascertained by the geophysics alone, as the unweathered kimberlite at L13 also appeared to have a similar density to the surrounding shale country rock.”

The report concludes, “One of the main objectives of doing the geophysical surveys was to delineate a body at L259 for drilling, and to map its size and shape. This has been achieved without a doubt, with good correlation between the gravity and EM surveys.”

Lucapa chief executive, Stephen Wetherall said that the Company was pleased with the results ofthe extensive surveys. “We have adopted a systematic approach to this area since identifying L259 as our most high priority kimberlite target at Lulo in late 2015 and the geophysical and geological work programs recently concluded at L259 have now provided us with target areas for the upcoming drill program.”

The drill programme aims to confirm the presence of kimberlite materials and define kimberlite material suitable for sampling and treatment.
