NORTHWEST TERRITORIES – Kennady Diamonds of Toronto has received diamond recovery results from a 25-tonne mini-bulk sample take at the Kelvin kimberlite. The total sample graded 1.79 carats per tonne.
The Saskatchewan Research Council processed the sample using dense media separation. The sample was found to have a lower count of large diamonds than previous ones from Kelvin. The 2013 sample graded 4.32 carats per tonne.
The Kelvin kimberlite has four distinct kimberlite phases, and the samples prepared accordingly. The best grade was from coherent pyroclastic kimberlite (2.96 c/t), followed by pyroclastic kimberlite with small and medium xenoliths (2.13 c/t), coherent transitional pyroclastic kimberlite (1.56 c/t) and lastly pyroclastic kimberlite with rock flour and large xenoliths (0.84 c/t).
Said company CEO Patrick Evans, “A higher frequency of larger diamonds in previous samples resulted in sample grades well above two carats per tonne. The sampling and treatment methods used for the mini-bulk sample will be reviewed.”
