VANCOUVER, BRITISH COLUMBIA--(Marketwired - Mar 15, 2017) - North American Nickel Inc. (TSX VENTURE:NAN)(WSCRF)(CUSIP:65704T 108) (the "Company") is pleased to announce that it has received a report on the results of mineralogical studies performed by SGS Canada Inc. ("SGS") on four drill core samples of nickel-copper sulphides from the 2016 exploration program at the Maniitsoq Ni-Cu-Co-PGE sulphide project in southwest Greenland. The representative samples were obtained from the Mikissoq and P-058 mineralized norite intrusions at the Imiak Hill Complex and Fossilik area, respectively.
The objectives of the study were to determine the modal mineralogy, mineral texture, nickel, copper and cobalt deportment, and the liberation, association and exposure of the nickel, copper and iron sulphides of each sample. A copy of the report can be found on the Company website www.northamericannickel.com.
- 93.5 to 95.9% of the total nickel in each sample is contained within pentlandite. Potential pentlandite recoveries range from 94.9 to 96.8% based on liberation, association and exposure characteristics of crushed samples stage pulverized to 90% passing 150 micrometres;
- 2.3 to 4.4% of the total nickel in each sample is contained within pyrrhotite; and
- Pentlandite D50 (µm) grain sizes range from 42 to 46 micrometres.
- All copper is hosted by chalcopyrite. Potential chalcopyrite recoveries for the Mikissoq samples range from 90.6 to 94.3% based on liberation, association and exposure characteristics of crushed samples stage pulverized to 90% passing 150 micrometres. Potential chalcopyrite recovery for the P-058 sample is 75.2%; and
- Chalcopyrite P50 (µm) grain sizes range from 26 to 34 micrometres.
- Pentlandite and pyrite are the main hosts of the cobalt in the samples.
- Sulphide mineral species identified in each sample are pyrrhotite, pentlandite, pyrite and chalcopyrite.
- Orthopyroxene, amphibole, feldspar and clinopyroxene are the major silicates. Talc was identified by QEMSCAN in all samples and confirmed by XRD in two out of the four samples. Talc abundances (in crushed samples) were 0.88% for the P-058 sample and 4.1 to 10.1% for the Mikissoq samples.
North American Nickel CEO, Keith Morrison, states: "The results from the 2016 samples, which include the new sulphide lens at Mikissoq, continue to demonstrate the consistent nature of sulphide mineralogy, nickel deportment and potential pentlandite recovery of the Maniitsoq sulphide zones. Next steps in the evaluation of selected sulphide zones are expected to include initial bench scale flotation tests which will provide a first look at actual versus estimated nickel recoveries."
SUMMARY OF KEY STUDY RESULTS
Four representative drill core samples were collected in 2016 from new intersections of nickel-copper sulphides and were submitted to SGS Canada Inc. in Burnaby, BC for detailed mineralogical study. Three samples were collected from the new Mikissoq sulphide lens at the Imiak Hill Complex and one sample was collected from the P-058 target in the Fossilik area (see Table 1 and Figure 1). Samples consist of magmatic disseminated to blebby to net-textured sulphides having a maximum sulphur content of 12.5%.
Mineralogical analysis was conducted by QEMSCAN (Quantitative Evaluation of Minerals by Scanning Electron Microscopy), X-ray Diffraction (XRD) and Electron Microprobe Analysis (EMPA). Samples were analyzed both as core pieces (for mineral texture) and also stage pulverised to 90% passing 150 µm for modal mineralogy, grain size and process mineralogy characteristics (liberation, association and exposure).
Key results of the study are summarized below. Further details including sample preparation, methodology, technical definitions, modal analyses, and details of mineral chemistry as well as liberation, association and exposure characteristics can be found in the SGS report posted on the NAN website.

|Hole #||Ni (%)||Cu (%)||Co (%)||S (%)||Comments|
|D01728||P-058||MQ-16-105||1.42||0.10||0.04||6.54||Disseminated to blebby sulphides|
|D01729||Mikissoq||MQ-16-117||2.10||0.21||0.05||7.06||Disseminated to blebby sulphides|
|D01730||Mikissoq||MQ-16-117||3.63||1.07||0.06||12.50||Blebby to net-textured sulphides|
|D01731||Mikissoq||MQ-16-113||1.84||0.32||0.03||7.41||Disseminated to blebby sulphides|
The modal mineral abundances were determined in both drill core pieces and in crushed samples. Sulphide minerals comprise pyrrhotite, pentlandite, pyrite and chalcopyrite and the main silicate minerals are orthopyroxene, amphibole, clinopyroxene and feldspars. Talc was identified by QEMSCAN in all samples and confirmed by XRD analysis for samples D01728 from target P-058 and D01730 from Mikissoq. Talc abundances (in crushed samples) were 0.88% for the P-058 sample and 4.1 to 10.1% for the Mikissoq samples.
The D50 (µm) passing values determined on the crushed samples are presented in Table 2. This value is defined as the median grain size within the sample where 50% of the particles are coarser and 50% of the particles are finer than the particle size stated.

Nickel, Copper and Cobalt Deportment
Elemental deportment for nickel, copper and cobalt in each sample were calculated using the EMPA and QEMSCAN data and are shown (in wt %) in Table 3. On average, pentlandite accounts for > 93% of the total nickel in each sample. Pyrrhotite accounts for 2.3 - 4.4% of the total nickel and silicate minerals account for the remainder. Chalcopyrite carries 100% of the copper. Pentlandite and pyrite are the main carriers of cobalt. The deportment of cobalt in the samples is linked to the relative proportions of pentlandite and pyrite in the samples.

Potential Recovery of Pentlandite and Chalcopyrite
The potential recovery characteristics of pentlandite and chalcopyrite for the sample suite are summarized in Table 4. Potentially recoverable pentlandite ranges from approximately 95 to 97% for all samples. Potentially recoverable chalcopyrite ranges from approximately 90 to 94% for the Mikissoq samples and 75% for the P-058 sample. Talc could have a potential impact on the recovery of pentlandite through flotation unless managed during metallurgical processing, typically through the use of dispersants and talc depressants.
Potential recovery is the percent of the mineral (not value metal) that can potentially be recovered through flotation to produce a rougher concentrate. It is calculated using liberation, association and exposure of the grains (on a two dimensional surface area) and is used as a predictive tool to benchmark samples.
The following results are based on the mineralogical analysis and do not reflect other recovery factors that could occur in the actual metallurgical processes and should only be used as a guide to the metallurgical performance.
