The TPK property is in a structurally favourable geological setting where the Archean-aged Bartman Lake Greenstone Belt lies adjacent to a major bend in the regional scale Stull-Wunnummin Fault (Figure 3). The Property has been intruded by the 15 km long Freure Lake Batholith. A gold grain-in-till anomaly extends southwest from the southern edge of the batholith, suggesting that the associated bend in the Stull-Wunnummin Fault propagated a series of gold-bearing splay shears, concentrated along the southern margin of the structurally resistant buttress formed by the batholith. This metallogenic model is an analogous to that for the Malartic-Val d’Or gold district in Québec, where gold deposits are controlled by splay shears related to a major bend in the Larder Lake-Cadillac Fault and is hosted by the synvolcanic Bourlamaque Batholith and several smaller granitoid and porphyry stocks.
Big Dam Management Area (eastern area of the property)
Reverse circulation drilling and surface till sampling completed over this area of the TPK property:
- Identified a 6 x 11 km gold grain-in-till dispersal apron: with till samples returning up to 1,221 pristine gold grains (Figure 4): 10 grains from a 10 kg sample is considered highly anomalous.
- Regarded as one of the largest such aprons in North America and probably the largest if it extends almost 32 km across the property as Northern Superior suspects.
- Key fact to take away from this remarkable and unique geological feature is that it is impossible to get so many gold grains in the surface environment unless there is significant visible gold exposed at the bedrock surface for glacial ice to erode, transport and deposit.
- Discovery of key resources are inevitably discovered by tracing these dispersals to source. Examples of recent such discoveries are highlighted in the Corporate presentation located on this website (see Corporate Presentation, Northern Superior Resources Inc. web site www.nsuperior.com, Investor Centre): a) Agnico Eagle’s Meliadine (Nunavut) deposit; b) TMAC Resources Naartok (Nunavut) deposit; and c) New Gold’s Blackwater Creek (British Columbia) deposit.
To repeat from the opening page of this summary:
“gold grain anomalies of this scale are an amalgamated response from a cluster of gold zones which normally indicate a large gold district rather than a single zone” (see Northern Superior Resources Inc. press release, June 21, 2010).
The importance of predominately pristine gold grains within a gold grain concentrate from a till sample cannot be emphasized enough. The rule of thumb is that as gold, being very malleable, its original pristine wire- like shape is transformed to a “modified” form within 200 m from its source rock (see Corporate Presentation, Northern Superior Resources Inc. website www.nsuperior.com, “Investors” section).
The importance of the gold grain-in-till dispersal apron is accentuated by the presence of several gold and silver- bearing boulder trains embedded within the apron (Figure 5), returning assay values of up to 94.2 g/t Au. It important to note that:
- Assay values are superior to those determined from boulder dispersal trains associated with the Meliadine deposit(s) (see Northern Superior Resources Inc. press release, November 8th, 2017); and
- The head of these trains identify compelling mineral targets for both gold and silver (see Northern Superior Resources Inc. press release, November 8th, 2017).
- To date, diamond drilling has intersected up to 25.9 g/t gold over 13.5m within shear-zone hosted quartz veins. Notably, this was based on a low-priority target away from the core of the till dispersal apron, which has yet to be tested by drilling.
Annex Management Area (north-central area of the property)
Till sampling has identified a 3.5 x 10 km gold-in-till dispersal corridor (Figure 6)(Keely Lake gold grain-in-till dispersal corridor, see Northern Superior Resources Inc. press release, December 11, 2011):
- Till sampling and prospecting completed during 2017 successfully provided an up-ice cut-off for this corridor
- This gold grain-in-till corridor extends up to, and terminates at, a greenstone belt;
- Till samples have returned up to 1,690 pristine gold grains (see Northern Superior Resources Inc. press release, December 6, 2017).
Various prospecting programs (see Northern Superior Resources Inc. press releases, December 7, 2011; October 11, 2017) defined:
- Several mineralized boulders trains embedded within the head of the Keely Lake gold grain-in-till dispersal corridor (see Figure 7);
- Mineralized boulders returning assay values as high as 727 g/t gold, 111 g/t silver and 4.05% copper, these boulder trains;
- These assays consist of values superior to those determined from boulder dispersal trains associated with the Meliadine deposit(s) (see Northern Superior Resources Inc. press release, October 11, 2017); and
- Compelling mineral targets at the heads of these trains for gold, silver and copper (see Northern Superior Resources Inc. press release, October 11, 2017).
Limited diamond drilling in the area during 2012 intersected shear zones between felsic and mafic volcanics, which returned anomalous gold values, including 41.5 g/t over 0.6m.
New Growth Management Area (western area of the property)
The gold grain-in-till dispersal apron clearly defined within the Big Dam management area is thought to extend west another 24 km into the New Growth management area as defined by:
- Continuation of a major structure as defined by airborne geophysics;
- Dispersal of arsenic geochemistry from that same structure as defined by the geophysics (Figure 8; and
- Anomalous gold grain-in-till signatures, again emanating from that same structure.
Like the Annex management area, New Growth also has the potential to host gold, silver and copper:
- Highlighted by a 30+ cm wide bornite-chalcopyrite bearing quartz vein hosted in locally derived, moderately to strongly sheared monzonite boulder; and
- Returned values of 12.60 g/t gold, 111 g/t silver, and 4.05% copper (see Photo 1).
- Fourteen high priority drill targets are defined by a structural study completed from the Company’s proprietary airborne geophysical data (see Corporate presentation, Northern Superior Resources Inc. web site www.nsuperior.com, “Investor Center”), never prospected, never drilled.
