[{"type":"text","content":" VANCOUVER, British Columbia, Feb. 28, 2018 (GLOBE NEWSWIRE) -- North Arrow Minerals Inc. (TSXV:NAR) 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. Ken Armstrong, President and CEO of North Arrow, commented, “Diamond results from the 2017 mini-bulk sample have confirmed the presence of an important yellow diamond population in the A88 phase of the Q1-4 kimberlite. Further, the identification of the Green kimberlite as a new, previously unrecognized phase within Q1-4 underscores the under-evaluated nature of this diamond deposit. Q1-4 requires further evaluation, in particular the collection of a larger bulk sample of sufficient size to better determine the spatial and size distributions of Q1-4’s diamond population including potentially higher value coloured diamonds.” The 2017 mini-bulk sample consisted of 209.8 dry tonnes collected from a single sample pit at the multiphase Q1-4 kimberlite, located just seven kilometres from the Company’s laydown near the Hamlet of Naujaat, Nunavut. The overall sample was divided and processed separately as three subsamples: Green Kimberlite (31 bags; subsample C1), Blue Kimberlite (A88 phase; 60 bags; sub sample C2), and Mixed Blue-Green Kimberlite (159 bags; subsample C3). A summary of the diamond recoveries from each subsample is provided in the table below along with comparable results from the ...
