/CNW/ -- 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."
- Ian Bliss, President and CEO, Northern Shield
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 DasVision® 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.
Forward-Looking Statements Advisory
This news release contains statements concerning the exploration plans, results and potential for
porphyry copper, epithermal gold, nickel-copper-cobalt and other mineralization at the Company's
Root & Cellar and Property, geological, geophysical and geometrical analyses of the properties and
comparisons of the properties to known epithermal gold deposits and other expectations, plans,
goals, objectives, assumptions, information or statements about future, conditions, results of
exploration or performance that may constitute forward-looking statements or information under
applicable securities legislation. Such forward-looking statements or information are based on a
number of assumptions, which may prove to be incorrect.
Although Northern Shield believes that the expectations reflected in such forward-looking statements
or information are reasonable, undue reliance should not be placed on forward looking statements
