Brazil Minerals also announced that it has started the process towards a license for commercial mining of an highly promising adjacent site which contains auriferous and diamondiferous
gravel layer over 20 feet in thickness.
Chuck Fipke Dunnedin's exploration at Kahuna is focused toward the discovery of diamondiferous
Between 35 to 50 feet in depth the desired auriferous and diamondiferous
gravel layer appears, followed by bedrock at about 60 feet.
It is possible that some of these phases may be reassessed to enable a change to the grade and estimated tonnage of the diamondiferous
kimberlite in the pit.
March 01, 1967 is the day that Botswana entered the world diamond scene, as the first diamondiferous
Kimberlite known as B/K1 pipe, was discovered 15 kilometres north of Letlhakane.
In March, ALROSA conducted an experiment to clarify the diamondiferous
nature of the northwestern part of the Zapolyarnaya pipe at the Verkhne-Munskoye deposit.
Mountain Province said the transaction adds Kennady's 100% owned diamondiferous
bodies, which contain indicated resources of 13.62 m carats and inferred resources of 5.02 m carats, and adds 67,164 hectares of highly prospective and 100%-owned exploration ground surrounding the Gahcho Kue mine.
Gahcho KuA(c) consists of a cluster of four diamondiferous
kimberlites, three of which are being developed and mined.
A registered alluvial diamond miner in the diamondiferous
Kono region of Sierra Leone extracted a 709 carats stone, believed to be the 13th-largest uncut diamond ever mined.
"So far we haven't been able to do detailed exploration, but this proposal is a win-win for all." However, he said diamond producer De Beers and Rio Tinto, which has already discovered a cluster of eight "diamondiferous
pipes" in central India, have been cold to the latest exploration idea, citing high risks of failure.
