TORONTO, Dec. 16, 2013 /CNW/ - Kennady Diamonds Inc. ("Kennady Diamonds", the "Company") (TSX-V: KDI) is pleased to announce the diamond recovery results from the 2013 Kelvin summer drill program at the 100 percent controlled Kennady North diamond project, located in Canada's Northwest Territories.
Approximately 3,454 kilograms of kimberlite was recovered from 21 holes drilled at the Northwest Lobe of the Kelvin kimberlite. The kimberlite was processed 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 caustic fusion.
The 2013 Kelvin summer drill program, with results summarized in Table 1 below, returned an average sample grade of 4.56 carats per tonne.

Kennady Diamonds CEO Patrick Evans commented: "2013 has been a remarkably successful year for Kennady Diamonds. Our two drill campaigns have produced results which far exceeded our expectations. We recovered a total of 4.3 tonnes of kimberlite from Kelvin containing more than 16,000 microdiamonds of which 474 are commercial size diamonds. The Kelvin summer drill program returned an outstanding sample grade of 4.56 carats per tonne and the winter program returned an exceptional sample grade of 8.13 carats per tonne, for a combined sample grade of 5.38 carats per tonne. These are amongst the highest kimberlite sample grades ever recorded and confirm that the Kelvin kimberlite has both a coarse diamond size distribution as well as the potential to host a high grade diamond resource".
Table 2 below provides details of the number and weight of the plus 0.85mm "commercial" size diamonds recovered from the Kelvin summer drill program. Diamonds larger than 0.85mm can be sorted into categories with different price points and are considered, under Canadian Institute of Mining ("CIM") guidelines, to have "commercial" characteristics.

A total of 362 commercial size diamonds were extracted from 3,314 kilograms of kimberlite from the Kelvin 2013 summer drill program. By comparison, 112 commercial size diamonds were recovered from approximately 1,000 kilograms from the Kelvin 2013 winter drill program. This illustrates a high degree of consistency between the 2013 summer and winter samples of approximately one commercial size diamond for every nine kilograms of kimberlite.
While the 362 commercial size diamonds from the 2013 Kelvin summer drill program were recovered from the Northwest Lobe of the Kelvin kimberlite, the 110 commercial size diamonds recovered from the 2013 winter program came from sixteen different drill holes across the approximate 1 kilometer strike of the Kelvin kimberlite. Based on this, it is apparent that the Kelvin kimberlite hosts commercial size diamonds across the length and breadth of the kimberlite.
As announced on August 6, 2013, the 2013 Kelvin winter drill program (summarized in Table 4 below) returned an exceptional sample grade of 8.13 carats per tonne, which included an extraordinary 2.48 carat diamond.

Patrick Evans added: "In addition to the outstanding sample grade, it is very encouraging to see the presence of a number of high quality macro diamonds without any inclusions. Together with grade, diamond quality is a key value driver."
Besides the outstanding sample grade, approximately 60 percent of the diamonds recovered from Kelvin during 2013 are classified as white and transparent. Most of the white diamonds have either no inclusions or only minor inclusions. Approximately 2 percent of the diamonds are classified as yellow and transparent with either no or only minor inclusions. The bulk of the remaining diamonds are classified as off-white and transparent. Photographs of the commercial size diamonds will be posted on the Company's website as soon as they become available.
Following the successful conclusion of the 2013 exploration program, preparations for the 2014 winter exploration program are underway. Further geophysics over the Kelvin and Faraday kimberlites, as well as new exploration targets outside of the Kelvin - Faraday kimberlite corridor, is scheduled to commence in February 2014. This will be followed in March 2014 by a much expanded drill program, including more than 10,000 meters of delineation and exploration drilling and the extraction of a mini-bulk sample of approximately 25 to 30 tonnes from the Kelvin kimberlite.
The 2014 winter program is expected to be completed by May with the results being announced in the third quarter of 2014. The Company plans to publish a maiden resource statement for the Kennady North project during the fourth quarter of 2014.
In the interest of time, micro diamonds in the smallest sieve size fraction (+0.075 to -0.106) were not recovered from the 2013 summer sample. While this size fraction usually contains a large number of diamonds, they are very small and of no scientific or commercial value for a diamond project as advanced as Kennady North. For example, 3,139 micro diamonds out of a total of 8,708 diamonds were recovered in this size class from the Kennady North 2013 winter sample. Despite the large number of micro diamonds, exclusion of this size class has no material impact on sample grade or forecasting the distribution of larger stones.

About Kennady Diamonds
Kennady Diamonds Inc. controls 100 percent of the Kennady North project which comprises thirteen leases and claims located immediately to the north and west of the four leases controlled by the Gahcho Kué Joint Venture between De Beers Canada (51%) and Mountain Province (49%) located in Canada's Northwest Territories.
Kennady Diamonds aims to identify a resource along the Kelvin - Faraday kimberlite corridor of between 5 and 8 million tonnes, and also to identify new kimberlites outside of the corridor. This tonnage estimate is based on the drilling completed to date. The potential quantity is conceptual in nature as there has been insufficient drilling to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
