Botswana Diamonds reports grade of 78cpht at Vutomi

12 july 2017
Botswana Diamonds said the Vutomi prospect at Frischgewaagt (FGT) in South Africa has an indicated medium grade of 78 cpht in a range of 64 to 110 cpht at a bottom cut off of +1 mm after the inclusion of results of the bulk sample and an update to the estimation analysis technique.
The company also said that initial results indicated that the dyke system now covers 7.5km, up from 6km and that three anomalies had been defined, which could be “blows” on the dyke.
 A “blow” was where the dyke swells and may become a small pipe.
“An estimated midpoint grade of 78 cpht at Frischgewaagt is very good news,” said company chairperson John Teeling.
“The former Marsfontein mine is close by on the same dyke system had better grades and this was a blow.  Even better news is the identification of potential ‘blows’ on the dyke.  We will focus our upcoming drilling on these anomalies.”
It said a geophysics programme had been completed and evaluation was ongoing.
The drilling programme beginning in late July would focus on testing the anomalies with the intention of having an initial inferred resource by the end of the year.
