AFRICAN DIAMONDS, THE AIM LISTED DIAMOND EXPLORER ANNOUCES DRILLING DETAILS
* DRILLING BEGINS IN THE SEARCH FOR THE ORAPA ALLUVIAL DIAMOND DEPOSITS.
* SEVENTEEN HOLE DRILLING PROGRAMME COMPLETED ON THE ORAPA KIMBERLITES.
African Diamonds, through its wholly owned Botswana subsidiary, Kukama Mining
and Exploration (Pty) Limited have received the results of the ground based
gravity surveys conducted along survey lines in the Serowe License area by
independent geophysical contractors, Spectral Geophysics (Pty).
The surveys were conducted along six lines varying in length between 2 and 3
kilometers across an area where the company expects to locate ancient
palaeo-alluvial channels that drained the prolific diamond-rich Orapa kimberlite
field, approximately 100 kilometres to the northwest. The results of the
gravity surveys strongly suggest that the north-south extent of the projected
channel system is at least 5.5 km and that there is more than one channel within
the area investigated. The projected channels appear to represent different
ages of stream channel development.
The area selected for the gravity survey was previously covered by a detailed
aeromagnetic survey. The results from this aeromagnetic survey indicated that
the area is traversed by large dolerite dykes, giving rise to changes in bedrock
geology. This environment is believed to be favourable for the development of
trap sites and the deposition of diamonds.
It is expected that drilling will commence in this area during the course of the
week starting 13 October. The objective of the drilling will be to prove the
existence of the channels below the Kalahari sediments, which are of variable
thickness.
Orapa Kimberlite Drilling
Kukama has completed a seventeen hole drilling programme on four of the
twentyone kimberlites on the Orapa licence. All three kimberlites AK8, AK9 and
BK10 are known, from earlier drilling, to contain diamonds.
Over 1000 metres of drill spoil is presently being analysed with results
available late November.
John Teeling Chairman said "The Orapa Alluvials have never been discovered.
Several years exploration work by African Diamond directors have pinpointed
likely ancient river channels which flowed through Orapa. The purpose of this
drilling is to prove these channels exist. What makes this project so exciting
is the potential for high value gemstone diamonds. Diamond quality improves
with distance in an alluvial environment. Diamonds found in these channels are
likely to be superior to the average diamond production currently mined on the
Orapa and Letlekane mines. The drilling of the Orapa Kimberlites has gone well.
Within weeks results will be available to decide whether a pre-feasibility
programme can commence on one or more of these kimberlites which will aim to
recover 5000 carats for a detailed evaluation."
