Update on
· Bulk sampling (mining) on track to commence in Q2 2019 subject to approvals;
· 33 drill holes completed in the current programme to define the bulk sampling plan;
·
· Commissioning of the diamond processing plant which will process the
This programme comprised 33 holes and 1,282 meters of drilling which, together with previous work, has resulted in a total drilled depth of 3,299 meters in five areas on the two farms whilst BOD has been active on the property. The intensification drilling programme has allowed further definition of the kimberlite blow/fissure complex and added to data already generated by gravity, magnetic, maxmin and other advanced exploration techniques.
A summary of all of the data is provided in the following table by area drilled:

A bulk sampling target of 3.9 km of linear kimberlite fissure intersection has been identified from the results with intersections of up to 18 meters from 4 meters below surface. Areas hosting possible blows have also been identified, and these will form part of the bulk sampling (mining) area, which is adjacent to that from which a bulk sample was taken in early 2018 (which indicated diamond values of
Following refurbishment, wet commissioning has been concluded on a nearby kimberlite treatment facility where the bulk samples will be processed.
Early stage work is also progressing on potential secondary (alluvial) diamond deposits in the project area, with a number of targets being identified. The nearby and worked-out Marsfontein diamond mine was host to eluvial diamond deposits running at grades of 1,433 cpht.

Glossary
Kimberlite: Also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix.
Kimberlite Blow: Some kimberlite dykes are observed to expand along strike into lenticular features 10-20 times the dyke width and up to 100 m in length; these are termed "blows" and may represent the lowermost portions of root zone intrusions.
Wet Commissioning: Means water or a solvent has been introduced into the system and sub-systems.
CPHT: Carats per hundred tons.
