Strongbow Updates Spring Drilling at Nickel King, NWT

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 3, 2007) - Strongbow Exploration Inc. (TSX VENTURE:SBW) is pleased to provide an update on exploration drilling at the Company's 100% owned Nickel King project, NWT. Drilling and ground geophysical surveys commenced in late March as part of a $3 million exploration program intended to expand the areas of known sulphide nickel mineralization within the property. Current exploration highlights include:

- Ten drill holes (2,250 m) have been completed to date including seven holes (1,825 m) testing the along strike continuity of the Main Zone and three holes testing the Joe Island anomaly;

- The first three holes of the program, located 200 m apart, have confirmed the tenor of previously reported sulphide nickel mineralization within the Main Zone, returning 29.40 m grading 0.47% Ni, 53.75 m grading 0.48% Ni and 17.05 m grading 0.53% within the lower gabbro sill;

- Four additional drill holes have extended mineralization a further 800 m to the southwest, bringing the total strike length of the Main Zone to 1,600 m.

- Sulphide mineralization has also been intersected in three drill holes (425 m) completed over a 190 m strike length of the southern end of the Joe Island anomaly.

- Drilling and ground geophysics have been temporarily halted due to warming temperatures and the program is scheduled to recommence in mid June.

Strongbow has now received initial results from the first three drill holes completed within the Main Zone at the Nickel King property. The primary goal of drilling the Main Zone was to confirm the tenor of previously reported sulphide nickel mineralization and to test for the extension of the zone to the southwest along strike from a historic resource originally drilled by Inco in the 1950's. The historic resource has been defined over a strike length of approximately 800 m, and consists of 15 million tons grading 0.45% Ni and 0.12% Cu (0.1% Ni cut off), including 4.9 million tons grading 0.72% Ni and 0.19% Cu (0.5% Ni cut off). This historic resource has not been reviewed by a Qualified Person on behalf of Strongbow, is provided here for information purposes only and should not be relied upon. Nickel sulphide mineralization in the Main Zone is hosted within two arcuate gabbro sills that represent either discrete, stacked south dipping intrusions or the south dipping limbs of a westerly plunging synform. Typical mineralization encountered in the upper sill tends to be disseminated and more poorly developed than in the lower sill where the bulk of the historic resource was defined. The upper and lower sills range from 30 to 50 m and 45 to 65 m in thickness, respectively, and are separated by 50-75 m of country rock.

Drill holes NK07-01 through NK07-03 were each drilled 200 m apart in the central and westernmost portions of the Main Zone resource. The holes, all drilled at an angle of minus 85 degrees to the north, have confirmed the occurrence and tenor of nickel mineralization in upper and lower sills. Sulphide minerals, consisting of pyrrhotite with lesser chalcopyrite and very rare pentlandite typically comprise less than 5% of the upper sill. In the better mineralized portions of the lower sill the sulphide content typically ranges from 5 to 15%, occasionally reaching 30% over short intervals (typically less than 1 m).

Results for the first three drill holes are as follows:

An additional four drill holes have tested the southwest extension of the Main zone along the trend of a significant coincident magnetic/electromagnetic geophysical anomaly. Drill holes NK07-04, -05, and -06 were respectively collared 320 m, 600 m, and 850 m southwest from NK07-03. Each hole intersected sulphide mineralization similar in appearance to that encountered in the first three holes, however NK07-05 and NK07-06 each encountered only a single 75-100 m thick gabbro sill. NK07-05 was collared 80 m southwest of a historic Aber drill hole that returned 12.0 m grading 1.08% Ni and 0.26% Cu. The seventh drill hole of the program, NK07-07, collared 50 m east of NK07-05, was intended to test a secondary target near hole five but did not intersect significant sulphide mineralization.

The final three holes of the spring drilling program tested the southern end of the Joe Island target over a strike length of 190 m. Deteriorating ice conditions did not allow for testing the northern portion of this 500 m long geophysical anomaly. Each of the drill holes was oriented in an easterly direction at an angle of minus 85 degrees and encountered sulphide mineralization over widths of 2 to 10 metres at depths of less than 90 m down hole. The Joe Island area was previously tested by two Inco drill holes that reportedly intersected sulphide concentrations described in drill logs as weakly disseminated to 20% with assays ranging from trace to 0.2% Ni.

Samples from the remaining seven drill holes will be reported when available.

Spring drilling at Nickel King is part of a $3 million 2007 exploration program set to recommence in mid June with further drilling and ground geophysical surveys as well as property and regional scale mapping and prospecting. Summer drilling will concentrate on a number new land based conductive anomalies, including the Koona, Kizan, and Ring targets as well as further testing of the eastern extent of the Main Zone.

All samples from the drilling program were split with one half the core submitted to Acme Analytical Laboratories of Vancouver, BC for analysis. Each sample is weighed, dried and crushed to better than 70% passing a 2 mm screen. A split of up to 250g is taken and pulverized to better than 95% passing a 100 micron (150 mesh) screen. The prepared sample is subjected to either a hot aqua regia digestion (15g) or a four acid digestion (0.25g using nitric, perchloric, hydrofluoric acids, and hydrochloric acid). The resulting solution is analyzed by inductively coupled plasma - mass spectrometry (ICP-MS). Samples that return Nickel results greater than 5000 ppm are automatically re-analyzed using a four acid digestion with an ICP-emission spectrometry to provide optimum precision and accuracy. A quality assurance/quality control program is in place, with the insertion of standard, blank and field duplicate samples into the sample stream.

Strongbow's 2007 exploration programs are conducted under the supervision of David Gale, P.Geo.(BC), Vice-President of Exploration for Strongbow and a qualified person under NI 43-101.
