North Arrow Minerals Inc. recently completed the collection of a mini-bulk sample at the Q1-4 kimberlite at the Company’s 100% owned Naujaat (formerly Qilalugaq) and Mel Diamond Projects in Nunavut. This sample was collected as part of a $ 3.2 million summer exploration programme.

The Company reported that a total of 250 megabags of kimberlite with an approximate field weight of 234 (wet) tonnes, were collected from a single sample pit at the Q1-4 kimberlite. “Initial evaluation of the exposed kimberlite identified a north trending internal contact between distinct kimberlite phases,” North Arrow said. “Kimberlite to the west of the contact (Green Kimberlite) made up approximately 30% of the pit area and is described as a dark green, massive, very xenolith poor, very olivine rich, phlogopite coherent kimberlite with fine to very coarse macrocrysts (pre-dominantly olivine) and a good mantle sample. The remainder of the pit is comprised of a blue, massive, poorly sorted, xenolith poor, olivine rich volcaniclastc kimberlite with fine to very coarse olivine and a moderate mantle sample (Blue Kimberlite).”

The Company added that due to two distinct kimberlite units being present, the sample was divided into three subsamples: Blue Kimberlite (60 bags), Green Kimberlite (31 bags) and Mixed Blue-Green Kimberlite (159 bags).

Currently, the Company is involved in the final data collection, mapping and reclamation of the sample pit. “The sample will be shipped south on Naujaat’s annual sea-lift scheduled for arrival at the community on August 26th, and will be processed during the fall of 2017,” North Arrow declared. “The sample will be processed for the recovery of commercial sized (+0.85 mm) diamonds and the resultant diamond parcel will be used to provide a better understanding and indication of the diamond content, size distribution, and fancy colour diamond population within the sampled units.”

After analysis, the results of the current sample, and those from the ongoing delineation drill programme, will be used to plan collection of a larger bulk sample in 2018, the Company said.
