Explorer Kennady Diamonds on Monday said diamonds recovered from the 2013 summer drill programme at its Kennady North project, located in Canada's Northwest Territories, had confirmed that the Kelvin kimberlite had a coarse diamond size distribution and the potential to host a high-grade diamond resource.
The company, which was in 2012 spun out of New York- and Toronto-listed
Mountain Province Diamonds, said the results for the first seven
batches, totalling 1 527 kg, or about 40% of the 3 454 kg bulk sample,
returned a sample grade of 5.37 ct/t.
Bulk-sample testing were currently under way at the Geoanalytical
Laboratories Diamond Services, at the Saskatchewan Research Council,
which is accredited to the ISO/IEC 17025 standard by the Standards
Council of Canada as a testing laboratory for diamond analysis using
The kimberlite was recovered from 21 holes drilled at the north-west
lobe of the Kelvin kimberlite, and for processing purposes, the
kimberlite had been divided into 15 batches, each weighing about 220 kg.
"A sample grade of 5.37 ct/t is outstanding. The 2013 winter drill
programme returned an exceptional Kelvin sample grade of 8.13 ct/t,
which included an extraordinary 2.48 ct diamond. Adjusting for the
impact of the 2.48 ct diamond, there is a remarkable similarity between
the 2013 winter sample grade and the sample grade of the first seven
batches recovered from the 2013 summer programme,” Kennady Diamonds CEO Patrick Evans said.
A total of 154 commercial size diamonds were extracted from 1 527 kg
sample, and by comparison, 110 commercial size diamonds were recovered
from about 1 000 kg from the Kelvin 2013 winter drill programme. This
illustrated a high degree of consistency between the samples of about
one commercial size diamond for every 10 kg of kimberlite.
While the 154 commercial size diamonds from the first seven batches
have been recovered from the Northwest Lobe of the Kelvin kimberlite,
the 110 commercial size diamonds recovered from the 2013 winter
programme came from sixteen different drill holes across the 1 km strike
of the Kelvin kimberlite.
Based on this, it was apparent that the Kelvin kimberlite hosts
commercial size diamonds across the length and breadth of the
kimberlite, rather than being concentrated in particular areas, the
