Strongbow Exploration Inc. (TSX VENTURE: SBW) is pleased to provide
a summary and update of its wholly owned Snowbird nickel project,
including the Nickel King deposit. The Snowbird project extends for
over 200 km from northern Saskatchewan into the Northwest
Territories.
Ken Armstrong, President and CEO of Strongbow stated "Our
exploration efforts over the last three years have clearly
confirmed the potential of this area of central Canada to host a
new belt of nickel-copper sulphide deposits. We are well on our way
to defining a large, bulk tonnage Ni-Cu-Co deposit at Nickel King
with initial metallurgy demonstrating potential to produce a high
grade concentrate that would be attractive to domestic and foreign
consumers. Perhaps more importantly, 1.2 million acres of
prospecting permits acquired in 2007 have, through diligent
exploration, been narrowed down to approximately 78,000 acres
focused on high priority exploration targets to the south of Nickel
King. The discovery of nickel, copper and PGE mineralization in
previously unknown mafic and ultramafic intrusions in the Opescal
Lake, Heel and Dumas areas highlights the potential of the southern
Snowbird tectonic zone to host a number of magmatic nickel copper
sulphide deposits in addition to Nickel King. Strongbow is fully
permitted to carry out the next phase of exploration, including
drilling to test these priority exploration targets and expand the
Nickel King deposit."
Data compilation, modelling and target evaluation is ongoing for
the entire Snowbird project area. Important highlights for each of
the Nickel King, Opescal Lake, Heel, and Dumas areas are provided
below.
Nickel King
- Located in the Northwest Territories, 145 km northeast of
Stony Rapids, Saskatchewan;
- Mineral claims have been converted to mining leases, ensuring
long term, secure mineral tenure;
- The Nickel King Ni-Cu-Co deposit is hosted within two arcuate
stacked, moderately south-dipping norite sills;
- Mineralization has been traced over a total strike length of
approximately 2,600 m;
- Results of a final locked cycle metallurgical test projected
the grade of the final concentrate to be 16.5% Ni, 4.2% Cu and
0.74% Co. Recoveries of Ni, Cu and Co are given as 78.4%, 89.1% and
63.5%, respectively (Strongbow news release #09-08 dated July 15,
2009);
- A NI 43-101 compliant geological resource model has yielded
11.1 Mt grading at 0.40% Ni, 0.10% Cu and 0.018% Co containing
44,500 t of Ni, 10,600 t of Cu and 2,200 t of Co in the indicated
category. The total Inferred Resource is 33.1 Mt grading at 0.36%
Ni, 0.09% Cu and 0.017% Co containing 119,300 t of Ni, 29,000 t of
Cu and 5,600 t of Co. The reported base case resource was
determined at a 0.2% Ni cut-off (Strongbow news release #09-03
dated February 25, 2009);
- Strongbow estimates that between 10 and 27 million tonnes (Mt)
of 'potential resources' lie within areas of the geological
resource model. These 'potential resources' occupy gaps within the
NI 43-101 compliant resource estimate where there is insufficient
drilling to classify an inferred resource. Modelled resource blocks
falling within these gaps have instead been classified as
'potential resources'. Strongbow's estimate of the tonnage of these
'potential resources' has been determined by modelling the pierce
points of 23 proposed drill holes, representing approximately 5,200
m of drilling, through the geological resource model. 'Potential
resources' were estimated by adding together resource blocks that
i) fall within a 75 m area of influence around each proposed drill
hole, and ii) were classified as 'potential resources' at a 0.2% Ni
cut-off within the geological resource model. The 27 Mt maximum
'potential resource' includes every resource block that satisfies
the two criteria above. The lower 10 Mt 'potential resource' was
determined by making a reasonable estimate of the minimum extent of
mineralization expected within these areas of the deposit. The
reader is cautioned that this estimate of 'potential resources' is
conceptual in nature, that there has been insufficient exploration
to define a resource in these areas of the Nickel King deposit and
that it is uncertain whether additional exploration drilling will
be successful in delineating a mineral resource in these areas;
- Significant potential to increase the size of the Nickel King
deposit has also been identified outside of the current resource
model. Ongoing geophysical and structural modelling suggests that
Nickel King mineralization may extend a further 600-700 m along
strike to the southwest of the current limit of drilling. The
deposit also remains open up dip and along strike to the east,
where geophysical surveys suggest mineralization could extend a
further 250 m;
- Strongbow's drilling discoveries of the Koona (1.0% Ni, 0.2%
Cu, 0.04% Co over 4.35 m) and South Ring (0.47% Ni, 0.27% Cu, 0.03%
Co over 21.2 m) prospects within three km of the main Nickel King
deposit confirm the potential of the immediate Nickel King area to
host near surface satellite deposits;
- The property also hosts at least nine additional high priority
geophysical targets and mineralized showings.
Opescal Lake
- Straddles the Saskatchewan/Northwest Territories border,
approximately 30 km southwest of Nickel King;
- Exploration work included airborne geophysical surveys,
limited bedrock mapping and geochemical surveys;
- Previously unrecognized mafic and ultramafic intrusions are
extensive;
- Nickel-copper sulphide mineralization has been discovered in
at least five areas;
- Fifteen priority electromagnetic geophysical targets have been
identified including two parallel coincident
magnetic-electromagnetic anomalies that represent the most
compelling regional exploration targets identified to date. These
overburden covered targets are each over 800 m in length, have
geophysical responses similar to Nickel King and coincide with
anomalous biogeochemical (spruce tree) survey results;
- Best mineralization has been discovered at the OPN target
where five of six grab samples returned from 0.2% Ni to 1.17% Ni.
Mineralization at OPN is coincident with a 770 m long, high
priority (greater than 1,000 siemens) geophysical anomaly
(Strongbow news release #09-11, September 16, 2009);
- Mineralization at the Skip showing returned 4.2 g/t Au, 0.8
g/t Pt and 0.8 g/t Pd, indicating potential for platinum group
element mineralization.
Heel
- Located 70 km southwest of Nickel King and 70 km northeast of
Stony Rapids, SK;
- Exploration work at Heel has included airborne geophysical
surveys, limited bedrock mapping and geochemical surveys;
- Numerous mafic/ultramafic intrusions have been mapped in the
area including two stacked northeast-dipping norite sills very
similar in character to the norite sills hosting mineralization at
Nickel King. The stacked sills are proximal to a 500 m long
geophysical target that coincides with a soil geochemical and
biogeochemical anomaly;
- Nickel sulphide mineralization has been identified in three
areas, including the Laura showing, which has returned from
background values up to 0.49% Ni and 0.27% Cu from relatively weak
mineralization. The showing coincides with a high priority
geophysical target;
- Mapping by the Saskatchewan Geological Survey in 2009 also
identified a series of additional gabbro, norite and pyroxenite
intrusions in and around the Heel area.
Dumas
- Located from 30 to 35 km north of Stony Rapids, SK;
- Three separate target areas have been defined where
mafic/ultramafic intrusions coincide with multiple geophysical
anomalies;
- Drilling in 2008 discovered magmatic sulphide mineralization
in the Nickel Lake and Dumas Lake areas;
- The Nickel Lake discovery consists of a single drill hole
returning 0.8 m grading 1.89% Ni, 0.96% Cu and 0.11% Co within a
highly strained mafic intrusion. The discovery hole tested the
centre of a 550 m long coincident magnetic and electromagnetic
anomaly. Geochemical surveys suggest that disseminated sulphide
mineralization could extend for several hundred metres beyond the
geophysical anomaly.
The discovery of additional nickel copper sulphide deposits at
the Opescal Lake, Heel or Dumas areas would assist the evaluation
and potential development of the Nickel King deposit. Subject to
financing requirements, Strongbow is planning a 2010 drilling
program to test these regional exploration targets and to define
the extent of mineralization at Nickel King. Strongbow's 2010
exploration programs are conducted under the supervision of David
Gale, P.Geo.(BC/NT), Vice-President of Exploration for Strongbow
and a qualified person under NI 43-101.
