THORNY RIVER DRILLING DISCOVERS ADDITIONAL KIMBERLITE. MINE PLAN BEING PREPARED

Botswana Diamonds plc ("BOD"), the London AIM and BSE listed diamond explorer, is pleased to announce results from its latest drilling campaign on its Thorny River diamond project in South Africa.

Highlights

• 12 reverse circulation holes completed in recent drilling campaign
• 52 metres of kimberlite found, the largest intersection being 22 metres
• 2 new blows discovered which will increase the mineable kimberlite
• Mine plan being finalised
• Mining permit application being prepared

Chairman, John Teeling commented: "We have finished exploration and now move toward mine development. We already have a good understanding of how the mine will look. The recent drilling identified the entry point for a mine. The next stage is to refine the mine model and to apply for a Mining Permit".

Detail

The objective of this drilling campaign was to expand the mineable kimberlite for the purpose of mine planning. Twelve reverse circulation holes over five targets were drilled for a total of 536m. Analysis of raw data shows that two of the targets resulted in the discovery of new sub-surface blows which will be added to the inventory, whilst one shows promise (having produced kimberlitic indicators) but needs further definition work and the remaining two targets do not merit further work. The in-hole kimberlite intersections totalled 52 metres, the longest being a vertical intersection of 22m. The two additional blows are on-strike and 200m and 700m east from the River and River Extension blows.

The next steps are to finalise a mining plan and to apply for a mining permit. A further announcement will be made in due course.
