Northern Shield Resources Inc. ("Northern Shield" or the "Company") (TSXV: NRN) is pleased to report results of the 3D induced polarization ("IP") geophysical survey completed at the Company's flagship Root & Cellar Property ("Root & Cellar" or the "Property") on the Burin Peninsula of eastern Newfoundland. The Property is being explored for porphyry copper ± molybdenum, gold and tellurium, and for epithermal gold-silver-tellurium.

A review of the first 3D inversion modelling of chargeability and resistivity over a 4.6 km² grid covering the Creston copper porphyry target has been completed with four priority targets defined (Figure 1a and b). Three, IP-1, IP-2 and IP-3, appear to be connected, lying in the same zone of elevated chargeability. The fourth, IP-4, is a separate target to the north and possibly related to the Conquest gold zone.

Target IP-1

IP-1 is a near-surface chargeability response of approximately 9.5 mV/V coinciding with a bornite / possible chalcocite occurrence found during ground truthing of the target. It plunges shallowly to the SE into the IP-2 anomaly.

Targets IP-2 & 3

IP-2 extends from near surface to approximately 450 m depth with chargeability responses from 9.8 to 12.5 mV/V, and resistivity averaging approximately 6,875 ohm-m - the strongest combined response in the survey and the highest-priority target from the survey.  IP-3 has a modelled chargeability of 9 to 11.2 mV/V at depths between 245 and 570 m and lies on the southern flank of a magnetic high that is interpreted as the porphyry intrusion that is driving the system (Figure 2). IP-2 and -3 combined, have a strike-length of approximately 1,000 m with a trend parallel to both the diatreme breccia complex and the copper (lead-zinc) mineralization in the neighbouring quarries. These anomalies are on the edge of the grid and hence their geometry and magnitude cannot be fully determined. They also lie outside the area of Northern Shield's soil geochemical sampling in an area that has not been evaluated by prior exploration.

Target IP-4

IP-4 measures approximately 240 m by 300 m in plan extending from near surface to approximately 400 m depth. It is characterised by chargeability of 8.5 to 9.0 mV/V coincident with resistivity averaging approximately 9,350 ohm-m, the most resistive area in the survey. This combination of elevated chargeability with strongly elevated resistivity is typical of disseminated sulphides hosted in quartz veins or silicified alteration.

Interpretation

The magnitude of the chargeability responses at Root & Cellar is consistent with expectations for the core of an alkalic porphyry system. Induced polarization responds to the surface area of sulphide rather than to copper grade, and alkalic mineralization is typically sulphide-poor and dominated by high-tenor copper minerals such as bornite and chalcocite. Higher chargeabilities in porphyry systems are usually attributed to the alteration cap that contains abundant disseminated pyrite and not the mineralized core.

"This survey has done exactly what we asked of it. It has taken a copper showing we could stand on and shown us that it is the near-surface expression of something considerably larger, extending several hundred metres to depth, to the southeast and still open. We now have a clear, prioritised basis for drilling. Also, beyond defining the copper target, the survey has identified an untested target that may be part of the Conquest Zone." 

Next Steps

Ground truthing of the targets continues and a permit for 15 new drill hole collars has just been received, in addition to the 14 that remain permitted from last year. Nine of these new drill hole collar locations are in the main Conquest Zone.

The DasVisionÂR 3D IP survey was completed by Abitibi Geophysics Inc. of Val-d'Or, Quebec. The survey used a distributed receiver array employing IRIS Instruments FullWaver technology in a pole-dipole configuration, with 100 m receiver dipole separations and current injections every 100 m over approximately 4.6 km². A total of 148 of 150 planned current injections were completed and 9,464 data points collected.

About Northern Shield Resources

Northern Shield Resources Inc. is a Canadian-based company, a leader in generating high-quality exploration targets, which views greenfield exploration as an opportunity to find a mineable, near surface deposit at relatively low cost. We implement a model driven exploration approach to reduce the risk associated with early-stage projects for ourselves, our shareholders, and the environment. This approach led us to option the Root & Cellar Property from a Newfoundland prospector, who discovered the copper mineralization, and then to its advancement to the large gold-silver-tellurium and porphyry copper system that it has become.
