North American Nickel is a mineral exploration company with 100% owned properties in Maniitsoq, Greenland, Sudbury, Ontario, and the Thompson, Manitoba nickel belt.
The Maniitsoq property in Greenland is district scale project at 4,841 square km. NAN's mineral exploration licence covers numerous high-grade nickel-copper sulphide occurrences associated with norite and other mafic-ultramafic intrusions. The 70km plus long belt is situated along, and near, the southwest coast of Greenland, which is ice free year round.
The Post Creek/Halycon property in Sudbury is strategically located adjacent to the producing Podolsky copper-nickel-platinum group metal deposit of Quadra FNX Mining. The property lies along the extension of the Whistle Offset dyke structure. Such geological structures host major Ni-Cu-PGM deposits and producing mines within the Sudbury Camp.
The Bell Lake property in Sudbury is a 256-acre property that covers approximately one kilometre of the Mystery Offset dyke or MOD. The MOD is interpreted to be an extension of the Worthington Offset dyke which hosts the new Totten Mine of Vale and the exciting Victoria Deep deposit of Quadra FNX.
VMS Ventures Inc. (TSX VENTURE:VMS) owns approx. 45% of NAN.
North American Nickel Inc. has provided an update on the exploration activities at its 100-per-cent-owned Maniitsoq nickel-copper-cobalt-platinum group metals sulphide project in southwest Greenland. Drilling has recently concluded, and demobilization of equipment and crew is in progress. During the 2014 field season, 39 diamond drill holes and one deepened hole totalling 8,773 metres were completed. Assay results have been reported for five holes and results for an additional 31 holes are pending. Remaining assay results will be reported at regular intervals over the coming weeks.
Regional exploration drilling
Twenty-two holes totalling 3,725 metres were completed, testing 14 regional targets located throughout the Maniitsoq property. Nineteen holes intersected prospective noritic and gabbroic rocks. Fourteen of these holes intersected sulphide mineralization for which assay results are pending.
- Three high-conductance off-hole anomalies were detected in a fluxgate borehole electromagnetic (EM) survey of MQ-14-071 at the P-053 target. The anomalies, which are amongst the strongest responses seen on the Maniitsoq property, are interpreted to be related to mineralized norite intersected in the hole;
- 10- to 50-metre intervals of disseminated sulphides hosted in norite at P-149, P-136 and P-030 targets;
- Six-metre interval of semi-massive sulphide and 16-metre interval of heavily disseminated to net-textured sulphides hosted in norite at the P-013 target;
- Decimetre-scale semi-massive and massive sulphide veins, and stringers over core intervals of up to 5.5 metres associated with norite in multiple holes at the P-058 target.
Imiak Hill complex (IHC) exploration
Drilling was recently concluded at the IHC with 5,048 metres of drilling completed in 17 holes and one deepened hole to test for extensions of mineralization intersected in 2012 and 2013. Assay results have been reported for five holes at Imiak Hill, and are pending for 11 additional holes from Imiak, Spotty Hill and Mikissoq.
Detailed structural and lithological mapping at the IHC has contributed significantly to the geological understanding of this structurally complex area. Mylonitie zones mapped on surface at Imiak Hill have been projected to depth and appear to correlate with similar mylonite zones intersected in drilling. Initial interpretation indicates the mineralized zones are truncated at depth, and additional work is required to better understand the structural complexities of these features at Imiak Hill.
A surface fluxgate electromagnetic test survey was completed by Crone Geophysics and Exploration Ltd. on selected lines over the Spotty Hill area in order to evaluate this instrumentation for future use on the project. In addition, fluxgate borehole electromagnetic surveys were completed in one hole at Imiak Hill and one hole at Mikissoq.
Imiak Hill drilling
Seven drill holes totalling 2,445 metres were completed at Imiak Hill to test for extensions of zones 10 and 30. Assays are pending for one hole, MQ-14-072, which intersected:
- A 19.5-metre interval from 170.6 to 190.1 metres of net-textured to semi-massive sulphides, interpreted to be the downplunge extent of zone 10;
- A 1.7-metre semi-massive sulphide interval of zone 30 mineralization from 202.75 to 204.5 metres.
Zone 30 is terminated downplunge as a result of interpreted displacement along a mylonite shear zone. Zone 10 was extended an additional 75 metres downplunge from historical drilling, and is structurally terminated at a similar depth to zone 30. Further data analysis and structural interpretation are continuing to evaluate the mineralization at Imiak Hill.
Spotty Hill drilling
Seven holes and one deepened hole totalling 2,057 metres were completed at Spotty Hill, with assays pending for six holes. The Spotty mineralization plunges steeply to the southeast, as interpreted from both drilling and borehole electromagnetics, and consists of:
- Wide zones of disseminated sulphides with internal zones of more highly conductive, semi-massive sulphides.
Borehole electromagnetic surveys indicate that the mineralized trend is open in a downplunge direction and more drilling is planned for this area in 2015.
Three holes totalling 546 metres were completed at Mikissoq for which assays are pending. Two holes intersected mainly gneissic country rocks and are interpreted to have been drilled off the plunge of the mineralization. A third hole, MQ-14-073, intersected mineralized norite including:
- A 45.6-metre interval from 57.75 to 103.41 metres consisting of disseminated and fractured filled sulphides;
- A 5.6-metre interval from 112.93 to 118.56 metres of net-textured to semi-massive sulphides.
Borehole electromagnetics surveys indicate the semi-massive sulphide intersection is located slightly above and right of the main mineralized horizon, which is interpreted to be plunging steeply to the northeast.
The company is pleased with the progress made in 2014 on this early-stage exploration project, including the expansion of the Spotty Hill and Mikissoq mineralization at the IHC, and significant new sulphide intersections at several regional exploration targets. In addition, new geological and structural interpretations are contributing to a better understanding of the geological model.
Based on the success of the current exploration program, the company anticipates another robust exploration program in 2015 consisting of drilling, airborne and ground geophysics, regional prospecting and geochemical sampling, and an expansion of detailed structural and lithological mapping.
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;
- Gold, platinum and palladium lead fire assay on a 30-gram sample with ICP-AES finish;
- Samples with greater than 1 per cent nickel or copper were reanalyzed by sodium peroxide fusion, ICP-AES-calibrated for ore grade detection limits.
