Kennady Diamonds announced an “exceptional” sample grade of 3.55 carats per tonne for diamonds of commercial size that were recovered from its Kelvin North Lobe project in Canada. The three largest diamonds found were 0.67-carats, 0.23 carats and 0.15 carats.
The Geoanalytical Laboratories Diamond Services of the Saskatchewan Research Council processed the 0.93 tonne sample, according to a Kennady statement December 17.
So far in 2015, Kennady has processed 14.7 tonnes of core samples from the North Lobe, returning an average sample grade of 2.83 carats per tonne. The group intends to recover a bulk sample of around 500 tonnes in February or March 2016, with results expected in the middle of the year. The sample is expected to deliver more than 1,200 carats to support revenue modeling for the Kelvin kimberlite.
The company had announced a grade of 3.4 carats per tonne from another sample taken from the North Lobe earlier this month.
