Overview - The Naujaat Diamond Project

Details on the NI 43-101 Resource

The 12.5 hectare Q1-4 kimberlite is the largest diamondiferous kimberlite pipe in the eastern Canadian Arctic. The May 2013 Technical Report outlines an Inferred Mineral Resource at Q1-4 estimated to be 26.1 million carats total diamond content (assumes 100% recovery) from 48.8 million tonnes total content of kimberlite with an average +1 DTC total diamond content of 53.6 carats per hundred tonnes (cpht) extending from surface to a depth of 205m.

Additional resource upside in the form of a target for further exploration was estimated at between 7.9 to 9.3 million carats of diamonds (from 14.1 to 16.6 million tonnes total content of kimberlite with an average +1 DTC total diamond content of 56.1 cpht (assumes 100% recovery), extending from 205m depth to 305m depth. The mineral resource estimate comprised the integration of kimberlite volumes, density, petrology and diamond content-data obtained from 5,133 m of diamond drilling, 2,714 m of reverse circulation (RC) drilling, 2.9 tonnes of samples submitted for microdiamond analysis, 257.7 tonnes of samples submitted for macrodiamond sampling with 59.2 carats of diamonds (2,054 stones) recovered from RC drilling, 7.5 carats of diamonds (205 stones) recovered from surface trenching and 2.36 carats of diamonds (69 stones) recovered from HQ diameter diamond drilling.

The reader is cautioned that mineral resources are not mineral reserves and do not have demonstrated economic viability. In addition, the potential quantity and grade of any target for further exploration is conceptual in nature, there has not been sufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.

Project Update

On January 17th, 2017 North Arrow announced a property purchase agreement with Stornoway Diamond Corporation under which North Arrow will acquire Stornoway’s remaining interest in the Qilalugaq Project to bring North Arrow's interest up to 100%.  Stornoway will retain a 0.5% gross overriding royalty on diamonds mined from the Naujaat (Qilalugaq) Project. North Arrow will also make Cdn $2.5M cash payment to Stornoway at the same time that the first royalty payment relating to Naujaat (Qilalugaq) are payable.

Most Recent Work Programs

During the summer of 2014 North Arrow collected an approximate 1,500 wet tonne sample from the Q1-4 kimberlite for the purpose of recovering a larger parcel of diamonds to better determine diamond content, size distribution, diamond parcel value, and to establish whether or not coloured diamonds persist into the larger diamond sizes. The sample was collected by surface trenching an area of Q1-4 where there is limited (<1m) overburden cover.

On May 5, 2015, North Arrow reported final diamond recoveries from the sample, recovering 384.28 carats from 1,353.37 dry tonnes including 15 stones over 1 carat. The largest three diamonds were 4.42 carats (intense yellow cubic aggregate), 4.16 carats (greenish yellow cubic aggregate), and 3.53 carats (pale yellow cubic aggregate).  Yellow diamonds, representing a range of hues and tones, comprised approximately 9.0% by stone count (21.5% by carat weight) of the +1 DTC diamonds.

The parcel of 383.55 carats of diamonds was valued by WWW International Diamond Consultants (WWW) with results announced on June 9, 2015 with a modelled range of possible values from a possible low of $43 per carat and a possible high of $92 per carat. The primary conclusion reached by WWW was that the valuation results and modelled values should be treated with considerable caution when assessing the Qilalugaq Project due to the very small size of the diamond parcel. 

In addition to its small size, the valuation of the Q1-4 diamond parcel was further complicated by the unusual occurrence of two identifiable diamond populations including a population of rare Type IaA - Ib coloured diamonds. In December 2015 North Arrow initiated a polishing exercise on select coloured diamonds. The purpose of this exercise was to address several of the outstanding questions related to these diamonds including their suitability for polishing, potential yield, and final polished colour. Initial results from this work have confirmed that i) a portion of the yellow diamond population are fancy orangey yellow diamonds that would be desirable for use in the gem and jewelry trade and ii) the presence of these fancy coloured diamonds and the fact that they have proven to be a younger, distinct population with potentially, a more coarse distribution that the white diamonds, could have a significant positive impact on the overall value of the Q1-4 diamond population. As a result of this this polishing exercise and related data analyses,  a diamond drill has been mobilized to the project site in anticipation of a spring 2017 drilling program.
