North Arrow Minerals Inc. is pleased to report final diamond recoveries from a 209.8 tonne mini-bulk sample collected in July 2017 from the diamondiferous Q1-4 kimberlite at the Naujaat Diamond Project, Nunavut. Highlights of this announcement include:
•A total of 1,991 diamonds greater than +1 DTC (~1 mm) weighing 64.25 carats were recovered from 209.84 dry tonnes of kimberlite for an overall sample grade of 30.6 cpht (carats per hundred tonnes).
•The three largest recovered diamonds are 5.25, 2.09 and 1.06 carats.
•Yellow diamonds, representing a range of hues and tones, represent approximately 10.7% (by stone count) of the recovered diamonds (21.2% by carat weight).
•Diamonds recovered from a subsample of the A88 phase ('Blue' kimberlite) include a similar proportion of yellow diamonds as seen in 2014 sampling of the A28 phase.
•The 'Green' kimberlite unit, also processed as a separate subsample, is interpreted as a previously unrecognized and volumetrically minor unit in the Q1-4 kimberlite and contains proportionately fewer coloured diamonds than the A88 and A28 phases.
