Update on Thorny River project development
-- 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;
-- Thorny River drill plan concluded with data from a total of 77 holes drilled
-- Commissioning of the diamond processing plant which will
process the Thorny River kimberlite has been completed.
Botswana Diamonds ("BOD") the AIM and BSE listed explorer is
pleased to announce that the intensification drilling programme has
been concluded on the farms Frischgewaagt and Hartbeesfontein which
form part of the Thorny River project. The purpose of this drilling
programme was to enable detailed planning for a bulk sampling
(mining) programme, which will commence after the necessary
regulatory approvals have been received; these are expected during
the course of Q2 2019.
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

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 US$120 - US$220 / carat and grades of
46 - 74 carats per hundred tonnes (or in-situ value of US$55 -
US$160 / tonne)).
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.
