Results of 5.1 carats per tonne from Kennady Diamonds’ (TSXV:KDI) Faraday kimberlite rank among the highest sample grades recorded in Canada, the company stated on August 5. A 933-kilogram sample pulled out of the Northwest Territories tundra last spring revealed 4,628 diamonds in sieve sizes that began in the 0.106-to-0.15-millimetre range and maxed out at the 2.36-to-3.35-mm range, although most came in at the smaller sizes. Ninety-seven stones ranked above 0.85 mm, meaning they “can be sorted into categories with different price points and are considered, under Canadian Institute of Mining guidelines, to have ‘commercial’ characteristics,” Kennady maintained.
More important than grade is the diamonds’ quality.
“Almost all the ‘commercial’ size diamonds are described as transparent and either white/colourless or off-white,” the company added. “Approximately 75% have either no or only minor inclusions [impurities].” By weight, recovery of commercial sizes graded 3.88 carats per tonne.
Kennady provided descriptions of the sample’s three largest diamonds: a 0.4-carat off-white, transparent, octahedral shape with minor inclusions; a 0.25-carat white/colourless, transparent, octahedral with inclusions; and a 0.22-carat white/colourless, transparent, aggregate with inclusions.
The Kennady North project hosts four known kimberlites. The Faraday and Kelvin kimberlites have delineation drilling underway while results for Kelvin’s latest 25-tonne bulk sample are expected in Q4. Late last month the company announced Kelvin’s widest kimberlite intercept so far, 183 metres (not true width) starting at a downhole depth of 151 metres.
The project borders on three sides Gahcho Kué, “the world’s largest and richest new diamond development project,” according to partners De Beers (51%) and Mountain Province Diamonds TSX:MPV (49%). They have production scheduled for 2016.
Adjacently south of Gahcho Kué and east of Kennady is the 42,000-hectare Godspeed Lake property acquired by Prima Diamond TSXV:PMD last month.
