North American Nickel Inc. has received assays from three 2016 drill holes completed at the Mikissoq target in the Imiak Hill Complex (IHC) area on its 100-per-cent-owned Maniitsoq nickel-copper-cobalt-platinum-group-metal sulphide project in southwest Greenland. The company completed a total of 9,596 metres of drilling during the 2016 exploration program.
The initial 2016 drill hole (MQ-16-113) tested a borehole electromagnetic (BHEM) anomaly beneath existing drilling and intersected a wide new zone of norite-hosted nickel and copper sulphide mineralization. Two additional holes (MQ-16-117 & 118) intersected the down dip extension of the same zone.
-- MQ-16-113: 53.25m @ 0.81% Ni and 0.36% Cu (1.04% Ni Eq)
Including: -- 5.15m @ 2.56% Ni and 0.37% Cu (2.92% Ni Eq)
-- MQ-16-117: 74.05m @ 1.08% Ni and 0.54% Cu (1.44% Ni Eq)
Including: -- 13.65m @ 1.84% Ni and 0.64% Cu (2.30% Ni Eq)
-- MQ-16-118: 47.00m @ 0.51% Ni and 0.25% Cu (0.71% Ni Eq)
Including: -- 15.00m @ 1.03% Ni and 0.32% Cu (1.30% Ni Eq)
NAN CEO, Keith Morrison, commented: "These exceptional new drill results at Mikissoq have transformed the target from a small area of near surface mineralization into a wide lens of high nickel tenor magmatic sulphides that extends to a vertical depth of 350 metres and remains open. The discovery of this new zone contributes to existing zones at both Imiak Hill and Spotty Hill, all located with 1.5 kilometres of each other. Defining the size of Mikissoq will be a priority for NAN next year."
This release summarizes the results for three holes totalling 1,167 metres completed at the Mikissoq target in the IHC area which is located in central portion of the Greenland Norite Belt (Figure 1). One additional hole has been completed at Mikissoq for which assays are pending. Drill collar information and a summary of assays are provided in Tables 1 and 2, respectively. A drill plan and drill cross section are given in Figures 2 and 3, respectively. Figures may be viewed using the link provided with this release: http://media3.marketwire.com/docs/1074406_F1-3.pdf.
During the 2016 exploration program, 30 drill holes and two hole extensions totalling 9,596 metres were completed. Assay results have now been reported for 14 holes and one hole extension totaling 4,410 metres, including those reported herein.
Three holes completed at Mikissoq have intersected a new zone of norite-hosted mineralization located 130 metres below previously intersected shallow mineralization at Mikissoq. The new zone has been intersected over a dip extent of 105 metres and consists of coarse grained magmatic disseminations and blebs, locally with remobilized sulphide stringers and veins. The mineralization is characterized by high nickel tenors (percent nickel re-calculated to 100% sulphides) of typically between 8 and 11%. A fourth hole collared 45 metres along strike to the northeast intersected a wide interval of weakly disseminated sulphides in norite for which assays are pending. The zone remains open down dip and along strike to the southwest.
The new discovery at Mikissoq demonstrates the potential to identify significant new sulphide lenses which can be targeted by BHEM but have footprints significantly larger that the BHEM anomalies due to the electrically disconnected nature of the sulphides. The Company plans to carry out 3D modeling of the larger IHC area incorporating all exploration data, including the results of the 2016 induced polarization (IP) survey, to help define continuations of the mineralized norite stratigraphy and aid in future drill hole targeting.
Hole MQ-16-113 tested a moderate conductance off-hole BHEM anomaly detected from previous hole MQ-15-074 and interpreted to be a possible off-set continuation of the shallow Mikissoq mineralization bounded along the northwest side by a mylonite zone (see Figure 3). MQ-16-113 intersected a norite body at depth hosting a wide interval of coarse sulphide disseminations, blebs and, locally remobilized stringers and veins that correlates with the targeted BHEM anomaly. The mineralization graded 0.81% nickel and 0.36% copper over 53.25 metres from 233.75 to 287.00 metres and included several higher grade intervals such as 2.56% nickel and 0.37% copper over 5.15 metres (Table 2). The new norite body and sulphide zone are interpreted to lie on the same side of a bounding mylonite zone as the shallow Mikissoq norite and mineralization.
Hole MQ-16-117 intersected the continuation of the new zone 55 metres down-dip of MQ-16-113 (Figure 3). The style of mineralization was similar but with a higher overall sulphide percentage yielding higher grades:
268.70 - 342.75m: 1.08% nickel and 0.54% copper over 74.05 metres including -- 2.10% nickel and 0.44% copper over 5.30 metres and -- 1.84% nickel and 0.64% copper over 13.65 metres
Hole MQ-16-118 intersected the zone 50 metres down dip of MQ-16-117, extending the zone over a total dip extent of approximately 105 metres. Widths and style of the mineralization were similar to the first two holes but with lesser amounts of sulphides returning 0.51% nickel and 0.25% copper over 47.00 metres from 322.00 to 369.00 meters. Once again the zone contained a higher grade interval which returned 1.03% nickel and 0.32% copper over 15.00 metres.
A fourth hole was collared 45 metres along strike to the northeast of MQ-16-118 and intersected a wide zone of weakly disseminated sulphides for which assays are pending. The weaker nature of the mineralization suggests this hole may lie near the northeast edge of the new zone.
Preliminary 3D modeling of the drilling and surface geological data indicate that the new zone is sub-vertical and hosted within a second deeper norite body situated on the same (southeast) side of a mylonite zone which bounds the shallow norite-hosted Mikissoq mineralization (Figure 3). The new sulphide zone lies approximately 130 metres below the shallow mineralization. Borehole EM surveys of all holes show the conductive response for the new zone to be centred on hole MQ-16-117 with the footprint of the zone extending beyond the margins of the interpreted BHEM plates.
The drilling was completed by Boart Longyear Canada utilizing two Boart LF-70 diamond drill rigs. Drill core samples (40.54 mm BQTK and 47.6 mm NQ) are cut in half by a diamond saw on site. Half of the core is retained for reference purposes. Samples are generally 1.0 to 1.5 metre intervals or less at the discretion of the site geologists. Sample preparation is completed at the ALS Minerals preparation lab in Ojebyn, Sweden. Sample pulps are sent by air courier to ALS Minerals analytical laboratory in Loughrea, Ireland. Blank samples and commercially prepared and certified Ni sulphide analytical control standards with a range of grades are inserted in every batch of 20 samples or a minimum of one per sample batch. Analyses for Ni, Cu and Co are completed using a peroxide fusion preparation and ICP-AES finish (ME-ICP81). Analyses for Pt, Pd, and Au are by fire assay (30 grams nominal sample weight) with an ICP-AES finish (PGM-ICP23).
