Kennady Diamonds Recovers 1.83 Tons of Kimberlite from Kelvin South Lobe
April 27, 15(IDEX Online News) – Kennady Diamonds Inc. has reported the results from the Kelvin 2014 summer/fall core drilling program. The miner recovered approximately 1.83 tons of kimberlite from the Kelvin South Lobe and 47.62 kilograms from the Kelvin Sheet.
Kimberlite from both areas was processed by caustic fusion at the Geoanalytical Laboratories Diamond Services of the Saskatchewan Research Council.
The 1.83-ton Kelvin South Lobe sample was recovered by HQ diamond drilling. These core holes also served as pilot holes for the 2015 Kelvin bulk sample, which was recovered using large diameter reverse-circulation drill rigs.
The four largest diamonds recovered from the Kelvin South Lobe sample were a 1.36-carat off-white, transparent, macle with inclusions; a 0.68-carat off-white, transparent, broken tetra-hexahedron with inclusions; a 0.44-carat off-white, transparent, fragment with minor inclusions and a 0.44-carat off-white, transparent, octahedral with inclusions.
The largest diamond recovered from the Kelvin Sheet sample is described as a 0.12-carat white/colorless, transparent octahedral with minor inclusions.
“We are very pleased with these excellent diamond recovery results, which returned a sample grade of 3.64 carats per ton from the Kelvin South Lobe and 5.95 carats per ton from the Kelvin Sheet for diamonds having commercial characteristics,” said Kennady Diamonds CEO Patrick Evans
“These results support the potential for the Kelvin kimberlite to host a high-grade diamond resource. Based on drilling and sampling completed to date, we estimate that the Kelvin – Faraday kimberlite cluster has the potential to host between 10 and 13 million tons at a grade of between 2 and 2.5 carats per ton."
As with previous Kelvin samples, the number of transparent white/colorless and off-white diamonds is very high. Of the 366 individual diamonds from the above samples described by the SRC, 46 percent are described as white/colorless and 51 percent as off-white. Six are described as yellow and only 5 as brown. There are no gray diamonds in the sample.
“Together with grade, diamond quality is a key indicator of value,” said Evans.
