The Maniitsoq property in Greenland is a district scale project comprising 2,985 square km covering numerous high-grade nickel-copper cobalt-PGM occurrences associated with mafic-ultramafic intrusions of the Greenland Norite Belt (GNB). This >75km-long belt is situated along, and near, the southwest coast of Greenland accessible from the existing Seqi deep water port with an all year round shipping season and abundant hydro-electric potential. Greenland is a democratic, pro-mining country with a transparent regulatory system, competitive mining tax and no land claim issues (Figures 1 and 2).The property is 100% owned by North American Nickel.
The project is centred approximately 125 km north of Nuuk, the capital of Greenland, and consists of two, contiguous, Mineral Exploration Licences (registration numbers 2011/54 and 2012/28) situated just east of the towns of Maniitsoq and Napasoq.
Early historical work on the property (1959-1973) consisted of geological mapping, prospecting and shallow diamond drilling. The result was the recognition of a 15 x 75 km belt of nickel-copper-bearing norite intrusions referred to as the Greenland Norite Belt. There was some notable success in the historic drilling particularly at Imiak Hill with a 9.85 m intersection grading 2.67% Ni and 0.60% Cu. A large fixed wing GeoTEM survey covering the GNB was commissioned by the Geological Survey of Greenland and Denmark (GEUS) in 1995 and flown by Geoterrex Limited. Between 1995 and 2000, the survey was followed up by two major mining companies: Cominco and Falconbridge, neither of which conducted any diamond drilling. However, both companies re-sampled historical drill core and confirmed many of the historical high-grade intersections as well as the generally strong nickel tenor of the sulphide mineralization throughout the entire GNB.
Subsequent to property acquisition, NAN has flown 13,497 line km of helicopter-borne SkyTEM/VTEM surveys between 2011 and 2015. These surveys were focused mainly on the GNB but also included several other prospective sites within the project area. Flight line spacing was 100-200 m and over two hundred electromagnetic (EM) anomalies were identified. Selected conductors were modeled and drill tested and mineralized norite was intersected at a number of locations including at the P-004, P-013, P-030, P-053, P-058, P-097, P-136, P-146 and P-149 targets. During the period 2012 to 2014, over half of the diamond drilling carried out by NAN was completed at the Imiak Hill Complex to test three mineralized norite intrusions: Imiak Hill, Mikissoq and Spotty Hill. This work identified zones of disseminated to massive sulphides at all three locations including significant high grade intersections such as 18.6m of 4.31% Ni and 0.62% Cu in drill hole MQ-13-026 at Imiak Hill.
North American Nickel has successfully completed year one and two of the three year strategy to carry out follow-up drilling at multiple mineralized targets identified in 2015 and 2016 in order to determine if one or more zones have the merit to warrant delineation drilling in 2017.
In 2015, the Company implemented an $8.3M exploration program consisting of 5,655 m of diamond drilling in 30 holes, a 6,696 line km helicopter-borne geophysical survey, 61.7 line km of surface electromagnetic (EM) surveying, a gravity survey, a ground geology program and acquisition of state-of-the-art Worldview-3 satellite data across the entire property. Integrated with our other exploration datasets, this new imagery provides NAN with the potential to directly target mineralization on the ground and to vastly improve on the level of mapping detail. (see Figures 3 and 4).
2015 drilling highlights included:
- Spotty Hill zone extended 80m in down plunge direction and still open
- Geophysical indication that Mikissoq continues in a down plunge direction
- New nickel-copper sulphide discovery at P-059
- Six widespread regional Ni-Cu sulphide occurrences (P-013, P-030, P-032, P-053, P-058 and P-059) with significant 2015 drill intersections.
The Company utilized these advanced targeting methods and the increased understanding of the nature of the mineralization and host rock and for 2016 aggressively completed 9,596 metres in 30 holes and two hole extensions testing the down plunge, strike extension, continuity and tonnage potential of mineralized zones assay results for 2016 still continue to be received and collated.
2016 Results to date include:
- New discovery of norite-hosted nickel and copper sulphide mineralization at Mikissoq
- New high grade nickel sulphide discovery at P-013 SE
- New high grade nickel sulphide intersections at the P-058 zone
- The expansion of the P-053 nickel sulphide zone
The company has reached an important point in the exploration of the Maniitsoq property in that we have now identified multiple centers of significant Ni-Cu sulphide mineralization (Figure 5) coupled with a better understanding of the geological setting as well as the nature of the mineralization and related geophysical responses. In addition, NAN is developing new regional and prospect scale targeting tools. The company anticipates a large follow-up drilling program in 2017 to drill test targets of merit from 2016 which have displayed continuity amongst multiple mineralized zones and demonstrate improving mineralization grades and widths with depth and will also be continuing the systematic exploration of the Maniitsoq property.
