Strongbow Announces NI 43-101 Compliant Indicated and Inferred Resource Estimates for Nickel King

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 25, 2009) - Strongbow Exploration Inc. (TSX VENTURE:SBW) is pleased to announce the first independent NI 43-101 compliant mineral resource estimate for the Main Zone deposit at Strongbow's wholly owned Nickel King project in southern Northwest Territories.

The Main Zone is hosted by two arcuate stacked, moderately south-dipping norite sills (the Upper Sill and the Lower Sill). Mineralization has been traced over a total strike length of approximately 2,600 m and remains open along strike, both down plunge to the southwest and also to the southeast.

"The release of this initial resource estimate for Nickel King confirms the potential of the Main Zone as a near surface, bulk tonnage nickel-copper-cobalt sulphide deposit," said Ken Armstrong, President and CEO of Strongbow. "The resource has been estimated from a relatively small number of drill holes considering the extensive strike length along which mineralization has been defined. This is reflected in a large portion of the resource falling within the inferred category and further untested potential remains within modelled areas of both the Upper and Lower Sills where drilling density is insufficient to categorize an inferred resource. Additional project upside exists in the form of i) mineralization remaining open along strike from the current mineral resource, ii) untested geophysical targets located both directly along strike and up dip from the Main Zone resource, and iii) the Koona and South Ring prospects, which represent potential near surface satellite deposits located within three kilometres of the Main Zone."

Petrographic and electron microprobe analytical studies have determined that silicate minerals within the host norite contain very low to negligible amounts of nickel. It is therefore anticipated that nearly all nickel reported in this resource estimate is contained in magmatic sulphide minerals and the use of a lower nickel cut-off grade than the 0.2% Ni base case may be possible. In order to assist in making this determination, Strongbow is commissioning a metallurgical study of the Main Zone utilizing drill core from the 2008 program. Results of this test work, expected by mid summer 2009, will provide Strongbow with initial metallurgical criteria including estimates of grindability, metal recovery and concentrate grade.

The resource estimate was completed by Pierre Desautels, P.Geo. of PEG Mining Consultants Inc., using industry standard methods that conform with the CIM Mineral Resource and Mineral Reserve definitions referred to in National Instrument 43-101, Standards of Disclosure for Mineral Projects, and utilizing Gemcom GEMS V.6.14™ software. The data and methodology utilized for the resource estimate is as follows:

- The Nickel King drill database consists of 97 diamond drill holes totalling 19,258 metres of core. During 2007 and 2008, Strongbow drilled 66 holes totalling 13,481 m or 70% of the drill database. The remaining holes consist of historical drilling performed by the Canadian Nickel Company (Inco) totalling 3,529 m in 18 holes (18%) and more recently holes from Aber Resources in 1995 totalling 2,249 m in 13 holes (12%). Of the total database, 70 drill holes were located within the Main Zone area and were used in the resource estimation, including 13 Inco holes which were used to confirm continuity of mineralization but not for grade determination due to incomplete sampling/assay information.

- A thorough QA/QC program was in place during the Strongbow drill programs, including the insertion of standards, duplicates and blanks at regular intervals.

- Three dimensional wireframe models of the Upper and Lower Sills were constructed based on lithological parameters. These domains were used to constrain the interpolation of the resource model. The total volume of the Upper Sill was determined as 29 million cubic metres and the volume of the Lower Sill was determined as 74 million cubic metres.

- Bulk densities were estimated using a regression analysis of 72 bulk density determinations performed by Strongbow. Densities used for the resource estimate range from 3.23 (0.15% Ni cut-off) to 3.35 (0.5% Ni cut-off).

- For the treatment of outliers, each statistical domain was evaluated separately for nickel, copper and cobalt using a decile analysis. Grade capping was not warranted for nickel grades, however copper and cobalt assays in the Upper Sill were capped at 0.45% and 835 ppm, respectively.

- A composite length of 2.5 metres was utilized to allow for about four data points in the 10 metre x 10 metre x 10 metre block matrix selected for the model.

- The resource model was interpolated using ordinary kriging. Inverse distance and nearest neighbour check models were also run for comparison and validation purposes. The interpolation was carried out in multiple passes with increasing search ellipsoid dimensions.

- Classification of the resource model was based primarily on the pass number and continuity suggested by the variography. A further adjustment to the classification was applied based upon i) the density of diamond drilling, and ii) the actual location of each block compared to the nearest drill hole trace. This adjustment disqualified potential resource blocks located further than 75 m from a drill hole in the Upper Sill and 100 m from a drill hole in the Lower Sill.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. This mineral resource estimate includes inferred resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that the inferred mineral resource will be converted to the measured and indicated mineral resource categories through further drilling, or into a mineral reserve once economic considerations are applied.

Pierre Desautels, P.Geo., of PEG Mining Consultants Inc., the Independent Qualified Person under National Instrument 43-101 responsible for the resource estimate, has reviewed this release. Mr. Desautels is the author of the resource estimate technical report on the Nickel King project to be filed within 45 days of this news release.

The Nickel King project is part of Strongbow's ongoing exploration of the Snowbird Tectonic Zone (SBTZ). The SBTZ is a major crustal scale structure and represents an underexplored region of Canada that is prospective for magmatic sulphide nickel deposits. Strongbow maintains a 100% interest in approximately 110,000 hectares of mineral claims, leases and permits along a 240 km strike length of the southern SBTZ. Outside of Nickel King, a number of priority exploration targets have been identified, primarily located in Saskatchewan. Strongbow's exploration programs are conducted under the supervision of David Gale, P.Geo. (BC), Vice-President of Exploration for Strongbow and a Qualified Person within the meaning of National Instrument 43-101.
