Sudbury, Ontario–(Newsfile Corp. – May 25, 2022) – SPC Nickel Corp. (TSXV: SPC) (“SPC Nickel” or the “Company”) reports that it has successfully concluded a reinterpretation of a 1994 ground based Total Field Magnetics and VLF-EM survey completed by BHP Minerals Canada Ltd.1 over the Marceau Lake Area of the high prospective Muskox Property (the ‘Property’) located in Nunavut, Canada (Figure 1).

Highlights from the reinterpreted Geophysical Survey include:

  • The presence of a broad conductive zone measuring 500 metres in strike length and up to 125 metres in width (Figure 2).
  • 2D inversions of the data indicate that the anomaly extends from surface to the depth limits of the survey (80 metres vertical) (Figure 3).
  • The anomaly is associated with the historic SKOX showing where values up to 1.90% Ni+Cu and 2.76 g/t Pt+Pd+Au1 have been reported historically from grab samples.
  • The magnetic survey clearly identifies the contacts of the Muskox Feeder dyke.
  • A positive correlation between nickel soil geochemistry anomalies and modelled VLF anomalies.

Figure 2: KH Depth slice (-67m) of the remodelled VLF-EM data. Conductive zones are shown in red/orange while resistive zones are blue/purple in color. Added to the map are the interpreted contacts of the Muskox Feeder dyke in the white dashed lines. Selective assay results1 from the area are shown as red circles with respective Ni+Cu wt.%/Pt+Pd+Au ppm values. Dashed red line is the approximate outline of the modelled conductive region. Note that grab samples are selective by nature and values reported may not be representative of mineralized zones. Note that the Karous-Hjelt Filter, named after Karous and Hjelt who calculated this in 19833. The Karous and Hjelt filter has been long time used as a qualitative interpretation of VLF-EM data. It is derived directly from the concept of magnetic fields associated with the current flow in the subsurface and resulted in a 2-D cross section showing the current density distribution at different depths.

Grant Mourre, CEO and President of SPC Nickel Corp. commented, “We are very encouraged by the results from the reinterpretation of the historic VLF-EM survey at Marceau Lake. The presence of large conductive regions associated with high-grade showings within the Muskox Feeder dyke are extremely exciting for SPC and further validates the potential of the property. The Marceau Lake area represent less than 5% of the 60 km Muskox Feeder dyke and has not been systematically explored in the past 30 years. We are looking forward to our first field program in late June when we will be visiting the Marceau Lake area and many other high-priority target areas.”

The Marceau Lake survey was completed by BHP Minerals Canada Ltd. in 1994 and consists of approximately 15 line km of combined Total Field Magnetics and VLF-EM data. SPC Nickel contracted Superior Exploration Co. Ltd. to complete modelling and a geophysical interpretation of the historic survey data which was digitized from historic maps in the original filed assessment report1. The survey results have been integrated with historical bedrock geology, grab samples, mineralized showings and soil geochemistry to produce target maps.

The geophysical interpretation has identified numerous VLF-EM anomalies and trends along the 4.0 km strike length of the Muskox Feeder Dyke covered by the Marceau Lake survey. Many of the anomalies are interpreted to be associated with geological contacts or structures within the surrounding country rocks, while other more prospective anomalies are clearly hosted within the Muskox Feeder dyke. Of particular interest is the large VLF-EM anomaly associated with the historic SKOX showing.

The geophysical modeling has identified a highly prospective anomaly hosted within the Muskox Feeder dyke with a strike length of 500 metres and a width up to 125 metres (Figure 2). A 2D inversion model demonstrates that the anomaly extends to at least a vertical depth of 80 metres (Figure 3), which is the depth limitations of the survey. The anomaly is associated with a pronounce flexure in the orientation of the dyke that is a common ore trapping feature observed in other dyke-hosted nickel systems such as at Sudbury and Voisey’s Bay.

The close association of the VLF-EM anomaly with known surface showings, high-grade grab samples and soil geochemical anomalies provides further validation of the anomalies. The nearby historic SKOX showing has returned base and precious metal values of up to 2.18% Ni, 2.13% Cu, 1.93 g/t Pd, 0.18 g/t Pd, 0.11 g/t Au and 7.50 g/t Ag1.

Staking

SPC Nickel is also pleased to announce that it has expanded the Muskox Property with the addition of three claims totaling 2,225 hectares (Figure 1). The claims were added to cover portions of the known Muskox Intrusion as well as visible gossans proximal to the contact of the intrusion. The current Muskox Property now covers 45,900 hectares in 14 mining claims and 2 prospecting permits.

Next Steps

SPC Nickel will be implementing the planned 2022 summer mapping and sampling program in late June.

About the Muskox Intrusion

The Muskox Intrusion is one of the last undeveloped camp-scale Nickel-Copper-Platinum Group Metals (“PGM”) prospects in the world. Originally discovered by INCO in the late 1950s during an aerial survey that discovered visible surface indications of mineralization (gossans) extending over tens of kilometres across the tundra. INCO drilled and sampled 117 shallow holes to test the gossans between 1957 and 1959 resulting in intersections of up to 7.6% Cu, 3.2% Ni and 16 g/t Pt+Pd+Au2 over 5.48 metres. Over the next 60 years, companies including Equinox Resources Ltd (1980s), Muskox Minerals Corp. (1995), Anglo American Exploration (2003) and Silvermet Inc. (2007) completed limited exploration programs on the Muskox Intrusion.

The Muskox Intrusion is one of the largest and least deformed layered mafic to ultramafic bodies in the world. It was emplaced during a large magmatic event (Mackenzie Magmatic Event) in the Proterozoic by mantle plume volcanism related to the widespread Coppermine River Group flood basalts. The intrusion is broadly composed of two distinct, but related, components called the Main Intrusive Body and the Feeder Dyke, which combined are exposed over a length of 125 km, and range in width from 200-600 metres in the Feeder Dyke to 11 km in the Main Body of the intrusion.

The Main Intrusive is a 60 km long by up to 11 km wide elongate-shaped body that is well differentiated and consists of gently inwardly dipping layers of dunite, peridotites, pyroxenites and gabbroic rocks. The total thickness of the exposed portion of the Main Intrusion is up to 1,895 metres based on drilling completed by the Geological Survey of Canada in 1963. Within the Main Intrusion, high-grade massive Ni-Cu-PGM sulphide mineralization occurs along the basal contact of the intrusion or in the adjacent footwall, similar to the Sudbury and Noril’sk camps, while narrow PGM-bearing chromite horizons occur within the upper stratigraphic units of the intrusion, similar to the Bushveld and Stillwater Intrusions.

The Feeder Dyke is exposed as a 60 km long, 200-600 metre wide dyke composed of picrite and bronzite-bearing gabbro in zones parallel to the dipping walls. Zones of disseminate to massive sulphide mineralization have been identified intermittently over the length of the dyke and are commonly associated with breccia zones or flexures within the dyke similar to what is observed at Voisey’s Bay and the Sudbury Basin.
