LONDON (Alliance News) - Botswana Diamonds PLC Thursday said four drill holes have been completed across two anomalies on its Orapa license in Botswana.
The update came from Sunland Minerals, the joint venture company owned 50% by Botswana Diamonds, who released the statement, with the remaining interest owned by Russia's OJSC Alrosa, who are operating the exploration programme.
Both holes drilled on anomaly 117/1 intersected altered, cracked and brecciated rocks composing veins between 5 centimetres and 10 centimetres, likely to be of kimberlitic origin. The samples are currently being processed, Botswana Diamonds said in a statement.
A vein is a distinct sheetlike body of crystallized minerals within a rock. In this case it has been found in a brecciated rock, which is a clastic sedimentary rock that can form in a variety of ways.
The two holes drilled on the other anomaly, AN117/2, failed to identify any kimberlites, it added.
"The discovery of kimberlite type material in holes 3 and 4 is very encouraging. This is the first time that Alrosa exploration technology has been applied in Botswana and these results support its use," said Chairman John Teeling.
Botswana Diamond shares were up 3.7% to 3.50 pence per share Thursday morning.
