North American Nickel Inc. has released new assays from its 100-per-cent-owned Maniitsoq nickel-copper-cobalt-PGM sulphide project in southwest Greenland including first results from the regional exploration targets. Thirty-nine diamond drill holes and one deepened hole totalling 8,773 metres were completed during the 2014 field season. Results for 23 holes are reported in this release including holes completed at the Imiak Hill complex (IHC) and at the regional exploration targets. The company is still awaiting assay results from 12 holes.
Highlights from the drill program include:
- Regional hole MQ-14-054 (P-058) intersected 1.72 per cent nickel (Ni) and 0.26 per cent copper (Cu) over 5.58 metres. All four holes drilled at the P-058 target intersected high-grade massive sulphide veins returning values of up to 6.18 per cent Ni and up to 3.95 per cent Cu.
- Regional hole MQ-14-041 (P-149) intersected 0.36 per cent Ni, 0.17 per cent Cu and 0.15 gram per tonne (g/t) platinum-palladium-gold (Pt-Pd-Au) over 23.2 metres including 3.31 per cent Ni, 0.61 per cent Cu and 0.27 g/t Pt-Pd-Au over 0.5 metre in norite-hosted disseminated sulphides. The P-149 (Pingo) target area is located 25 kilometres northwest of the Imiak Hill complex and outside of the currently defined Greenland norite belt.
- Regional hole MQ-14-051 (P-004) intersected 0.94 per cent Ni, 0.17 per cent Cu and 0.99 g/t Pt-Pd-Au over 4.31 metres.
- Assays are pending for disseminated to semi-massive sulphide intersections at the regional targets P-013, P-030 and P-053.
- MQ-14-058 (Spotty Hill) intersected two intervals of strongly disseminated sulphides grading 0.52 per cent Ni, 0.16 per cent Cu and 0.18 g/t Pt-Pd-Au over 38.65 metres and 0.55 per cent Ni, 0.11 per cent Cu and 0.2 g/t Pt-Pd-Au over 10.5 metres within a much larger interval of weakly disseminated sulphide grading 0.28 per cent Ni and 0.08 per cent Cu over 130.56 metres.
- Assays are pending for semi-massive and massive sulphide intersections from Imiak Hill, Mikissoq and Spotty Hill.
NAN president and interim chief executive officer Mark Fedikow commented: "I'm really excited by these regional discoveries which are returning high grades of nickel, copper and precious metals and have associated borehole EM anomalies. The Spotty Hill mineralization is returning wide zones of good nickel, copper and precious metal values and new intersections of net-textured to semi-massive sulphides make this a very prospective zone for future follow-up work. The new near-surface discoveries at Pingo, that are only three km from tidewater, lie northwest of the known limits of the GNB extending our area of exploration interest. Similarly, the high-grade nickel copper mineralization at P-058 and the disseminated to semi-massive sulphides intersected at P-013, P-030 and P-053 have strengthened the potential of the central and southern portions of the GNB. At the end of the year, with all assays returned, I am confident that we can communicate to our investors and supporters that North American Nickel via its 2014 exploration drilling and geophysical program has identified significant sulphide mineralization along the entire length of the Maniitsoq property."
Assay results have been received for 23 drill holes from the Imiak Hill complex and the regional targets as reported herein and provided in the associated tables. Selected drill core photos are included in a recent corporate presentation on the company's website.
Regional exploration targets
Twenty-two holes totalling 3,725 metres were completed to test 14 regional targets located throughout the Maniitsoq property. Assay results have been received for 16 holes and are pending for six additional holes.
Norite-hosted nickel sulphide mineralization has been confirmed at five regional targets: P-058, P-004, P-149, P-146 and P-136. Drilling at each of these targets was carried out to follow up initial helicopter-borne VTEM anomalies and, in some cases, to also follow-up nickel mineralization intersected in previous drilling. Results from the drilling and borehole EM (BHEM) surveys indicate that further exploration is warranted at each of these targets.
Four holes (MQ-14-053, 54, 57 and 59), totalling 505 metres, were completed to test an initial helicopter-borne VTEM target and subsequent BHEM anomalies located near the southwestern edge of the large Fossilik norite intrusion. Historical shallow drilling in this area returned values of up to 2.24 per cent Ni and 0.63 per cent Cu over 12.89 metres
All four of the 2014 holes intersected remobilized, structurally controlled high-grade massive sulphide veins associated with narrow intervals of foliated norite. Best results included:
- MQ-14-054: 1.72 per cent Ni and 0.26 per cent Cu over 5.58 metres from 70.6 to 76.18 metres including 6.18 per cent Ni and 0.56 per cent Cu over 0.62 metre and 5.23 per cent Ni and 0.07 per cent Cu over 0.81 metre;
- MQ-14-057: 1.35 per cent Ni and 0.10 per cent Cu over 1.57 metres from 112.11 to 113.68 metres;
- MQ-14-59: 2.54 per cent Ni and 2.75 per cent Cu over 1.74 metres from 22.26 to 24.0 metres including 4.19 per cent Ni and 7.73 per cent Cu over 0.45 metre.
Borehole EM results and modelling for the P-058 drill holes indicate the presence of two conductive trends related to the mineralization. The high conductance near-surface anomaly has limited depth extent but the deeper conductor indicates that the mineralization is open down plunge to the southwest and that conductivity thickness is increasing with depth.
The P-004 target is located at the southwestern edge of the Fossilik norite body and lies 500 metres northeast of target P-058. MQ-14-051 was drilled to test approximately 50 metres downdip of nickel mineralization intersected in 2013 in hole MQ-13-018 (0.59 per cent Ni and 0.18 per cent Cu over 32.19 metres including 1.06 per cent Ni and 0.23 per cent Cu over 4.53 m). MQ-14-051 intersected a zone of norite-hosted disseminated to net-textured sulphides deeper in the hole which graded 0.94 per cent Ni, 0.17 per cent Cu and 0.99 g/t Pt-Pd-Au over 4.31 m from 231.14 to 235.45 metres. Included within this zone was a higher-grade interval which returned values of 1.36 per cent Ni, 0.25 per cent Cu and 1.46 g/t Pt-Pd-Au over 2.65 metres including 2.34 per cent Ni, 0.34 per cent Cu and 0.73 g/t Pt-Pd-Au over 1.1 metres. The intersection occurred downhole of the target depth and data interpretation is under way to determine if the intersections in MQ-13-018 and MQ-14-091 are connected.
Two untested off-hole BHEM anomalies detected in the 2013 drill hole, MQ-13-018, lie southeast of the hole and warrant additional follow-up work.
A second hole, MQ-14-061 was drilled 285 metres to the east in an area of outcropping gossanous norite, previously tested by shallow historical holes, but did not return any significant nickel values.
The P-059 target is located 275 metres northwest of the P-58 target. One hole, MQ-14-055, was drilled to test an airborne VTEM anomaly but failed to intersect the conductor. A borehole EM survey of MQ-14-055 identified two off-hole anomalies located to the northeast and will require further drill testing to evaluate them.
P-149 and P-146 (Pingo area)
Drill holes MQ-14-041, 42 and 47 were drilled to test VTEM anomalies and gossanous norite in what is referred to as the Pingo area located approximately 25 kilometres northwest of the IHC. All three holes intersected norite-hosted, nickel-copper-bearing disseminated sulphide mineralization. Best results included:
- MQ-14-041 (P-149): 0.36 per cent Ni, 0.17 per cent Cu and 0.15 g/t Pt-Pd-Au over 23.2 metres from 85.35 to 108.55 metres including 3.31 per cent Ni, 0.61 per cent Cu and 0.27 g/t Pt-Pd-Au over 0.5 metre;
- MQ-14-042 (P-149): 0.44 per cent Ni, 0.20 per cent Cu and 0.21 g/t Pt-Pd-Au over 6.4 metres from 2.1 to 8.5 metres and 0.49 per cent Ni, 0.2 per cent Cu and 0.26 g/t Pt-Pd-Au over 3.9 metres from 77.85 to 81.75 metres.
The disseminated sulphide mineralization at the P-149 target is characterized by high nickel tenors and elevated precious metal (Pt-Pd-Au) contents similar to Spotty Hill. The linear Pingo norite unit trends northeast-southwest over a distance of approximately two kilometres with numerous pods of gossanous outcrop visible at surface. Prior to 2014, no surface geophysics and only one shallow historical drill hole had been completed in this area which lies well outside of the currently defined Greenland norite belt.
The P-136 target is located four kilometres southwest of the IHC. MQ-14-048 was drilled to test a VTEM anomaly in the vicinity of shallow historical holes which intersected norite-hosted nickel sulphides. MQ-14-048 also intersected several intervals of disseminated nickel sulphide mineralization grading 0.21 per cent Ni and 0.09 per cent Cu over 13.17 metres from 45.58 to 58.75 metres and 0.22 per cent Ni and 0.09 per cent Cu over 30 metres from 95 to 125 metres. A BHEM survey of this hole identified several untested off-hole EM anomalies. This area will be further evaluated for future surface geophysical surveys and follow-up drilling.
P-013, P-030 and P-053
Assays are pending for disseminated to semi-massive sulphide intersected in norite at the P-013, P-030 and P-053 targets.
Imiak Hill complex (IHC)
A total of 17 holes and one deepened hole, totalling 5,048 metres, were completed to test for extensions of the mineralization intersected in previous drilling at Imiak Hill, Mikissoq and Spotty Hill. Assay results were previously reported for five holes at Imiak Hill. Results for five holes and one deepened hole at Spotty Hill as well as one hole at Mikissoq are reported in the associated table and assays are pending for five additional IHC holes.
Drilling and borehole geophysics at Spotty Hill in 2014 have helped to define the nature and orientation of a broad zone of norite-hosted mineralization which is interpreted to plunge steeply to the southeast. The mineralization consists of zones of disseminated to heavily disseminated and patchy sulphides typically grading 0.5 per cent Ni or greater with internal zones of higher-grade semi-massive sulphides. This mineralization is surrounded by a halo of weakly disseminated sulphides typically grading 0.1 to 0.3 per cent Ni. The most highly sulphidic portions (semi-massive sulphides) of the zone can be correlated with moderate to high conductance BHEM anomalies, while the disseminated sulphide mineralization is correlated with a large, low conductance BHEM anomaly. The position of the latter anomaly indicates that the mineralized system is open down plunge to the southeast.
MQ-14-058 intersected disseminated sulphides which are interpreted to be part of the main mineralized zone and grade 0.52 per cent Ni, 0.16 per cent Cu and 0.18 g/t Pt-Pd-Au over 38.65 metres from 163.4 to 202.05 metres and 0.55 per cent Ni, 0.11 per cent and 0.20 g/t Pt-Pd-Au Cu over 10.5 metres from 213.3 to 223.8 metres. These intersections are within a much broader halo of weaker disseminated sulphides averaging 0.28 per cent Ni, 0.08 per cent Cu and 0.1 g/t Pt-Pd-Au over 130.56 metres from 116.7 to 247.26 metres.
Holes MQ-14-040 and MQ-14-052 intersected the low-grade nickel and copper mineralization which flanks the main zone of mineralization. MQ-14-044 was collared 300 metres to the south to test a separate EM anomaly interpreted from surface geophysical surveys. This hole intersected pyroxenite and country rocks but no significant mineralization. However, the borehole EM survey from this hole showed an anomaly building to the end of the hole which is interpreted to be related to the Spotty Hill mineralization. MQ-13-022 was deepened to test for mineralization along an interpreted norite-country rock contact and intersected disseminated low-grade sulphides as listed in the associated table.
Assays are pending for holes MQ-14-062 and 065, both of which intersected disseminated to semi-massive sulphides which lie within the main Spotty Hill mineralized zone.
Assays are pending for two holes including MQ-14-072 which intersected the down plunge extents of zone 10 (19.5 metres of net-textured to semi-massive sulphides) and zone 30 (1.7 metres of semi-massive sulphides).
MQ-14-60 intersected narrow intervals of unmineralized leuconorite and was drilled southeast of the main mineralized Mikissoq norite body which is now interpreted to plunge steeply to the northeast. Assay results are pending for two holes including MQ-14-073 which intersected:
- Approximately 45 m of disseminated sulphides;
- Approximately 5.6 m of net-textured to semi-massive sulphides in norite.
Drill core assay results are evaluated as part of a quality assurance and quality control procedure that includes the use of matrix matched multielement, certified standards with known precious and base metal values and blank standards to determine accuracy and precision of analytical results. Core sample analysis was completed by SGS Laboratories of Vancouver, Canada. Three methods of analysis were used to determine element concentrations in the rock samples submitted to SGS. These were:
- A multielement scan subsequent to a four-acid digestion and ICP/ICP-AES finish;
- Au, Pt and Pd lead fire assay on a 30-gram sample with ICP-AES finish;
- Samples with greater than 1.00 per cent Ni or Cu were reanalyzed by sodium peroxide fusion ICP-AES calibrated for ore-grade detection limits.
