Dunnedin Ventures Inc., an emerging diamond exploration company based out of Vancouver, BC whose main focus is the advanced stage Kahuna Diamond Project located in Nunavut, Canada, reports the recovery of 8.17 carats of commercial-sized diamonds (+0.85 mm) from 2.03 tons of ore from the PST kimberlite - one of three at the project. This yielded a final aggregate sample grade of 4.02 carats per ton. The largest diamond recovered at this stage was 2.22 carats. Chris Taylor, Dunnedin’s CEO said, “PST represents a high grade target with obvious capacity to host large and attractive diamonds. It is a clear target for further exploration and bulk sampling, and is one of several drill confirmed diamond-bearing kimberlites within a 2 kilometre radius. Once again, Dunnedin’s samples have returned higher than historic commercial-sized diamond grades. At PST our final aggregate sample grade is 84% higher than what was historically reported.”
Kahuna Diamond Project is an advanced stage high grade diamond project discovered in 2001. Three main diamondiferous kimberlite dikes have been discovered, the Kahuna, PST and Notch. Bulk sampling and drilling on the three main kimberlites has returned very high macrodiamond counts including diamonds over one carat in size. The largest diamond recovered was a 5.43 carat stone from the Kahuna dike that had been broken during the sample preparation process and was reconstructed as having an original size of 13.42 carats. The majority of diamonds at PST and throouout Kahuna are reported as clear and colourless to white, with a significant population of octahedral stones, however coloured stones have also been reported.
