Drilling at Botswana’s Kimberlite KX36 shows strong micro diamond results - Petra

15 march 2012

Petra Diamonds said exploration work at kimberlite KX36, which is situated in its Kukama East project area, in central Botswana has shown strong micro diamond results.
It said in a statement emailed to Rough & Polished that 250 diamonds, collectively weighing 0.756 carats, had been recovered from 403.88kg of kimberlite.
The largest diamond was a white, transparent dodecahedron, weighing 0.393 carats, it said.
"These initial drilling and microdiamond analysis results indicate that kimberlite KX36 has significant potential, in terms of its possible size, diamond grade and potential coarse diamond size frequency distribution,” said Petra chief executive Johan Dippenaar.
“The next step is a large diameter bulk sampling drilling programme, commencing in April 2012, in order to obtain further information with regards to grade and an indication of diamond value."
Company technical director Jim Davidson also said that the strong micro diamond results and the favourable coarser diamond size indications for kimberlite KX36 were most encouraging out of the five new kimberlites they had found in Botswana so far.
KX36 was approximately 60km from the nearest known kimberlite, meaning there was the potential for KX36 to be part of a new kimberlite field, he said.
