SASKATOON, SK,
The Mineral Resource Estimate ("Mineral Resource") was completed by A.C.A. Howe International Limited ("Howe") in accordance with Canadian Securities Administrators National Instrument 43-101 ("NI 43-101") and CIM Standards on Mineral Resources and Reserves. Indicated and Inferred Mineral Resources have been determined in the Red Zone (also referred to as the Main Zone) and six minor zones at the Jojay Gold Deposit. The Mineral Resources include 21 Wescan diamond drill holes completed in 2005 and 2007-2008 and 79 historic drill holes. At a block cut-off grade of 2 g/tonne Au, non-diluted Indicated mineral resources, located entirely in the Red Zone, amounted to 420,000 tonnes with an average grade of 3.7 g/tonne Au, for 50,000 ounces gold. Non-diluted Inferred mineral resources, approximately half of which were located in the Red Zone amounted to 630,000 tonnes with an average grade of 4.3 g/tonne Au, for 87,000 ounces gold. No Measured Resources or Reserves of any category were identified. Mineral resources are not mineral reserves and by definition do not demonstrate economic viability. There is no certainty that all or any part of the mineral resource will be converted into mineral reserve.
This NI 43-101 compliant resource estimate is a major milestone for the Jojay Gold Project. Wescan's exploration to date has confirmed and expanded a significant gold resource on the Jojay zone hosted by a continuous shear structure (i.e. Jojay structural zone) at a volcanic-sedimentary contact. The mineral resource estimate outlines the Red Zone and six minor mineralized zones. The zones are vertically dipping with a north-south strike. The Red Zone is modeled over a strike length of approximately 500 metres to a depth of 400 metres, and averages 4-5 metres wide. The Red Zone remains open down-plunge at depth.
The Jojay Deposit, as defined by the newly completed Howe mineral resource estimate, represents only a small portion of the (greater than)2.5 kilometre long prospective volcanic-sedimentary contact and coincident Jojay structural zone in the Jojay Property area. The Jojay structural zone is highly prospective and the model completed by Howe indicates that the Red Zone mineralization is open down plunge to the north-northeast and the potential for additional mineralization along strike may be present. Wescan believes that there is a strong potential to define additional mineral resources at the Jojay Deposit. Additional drilling is warranted to follow-up both the Jojay Deposit along strike and the Red Zone mineralized shoot down plunge.
Wescan is currently planning further drilling and an exploration program to expand the gold resource at the Jojay Deposit and assess other areas along the Jojay structural zone.
The Mineral Resource is summarized with various cut-off sensitivities in Table 1 below.

To carry out the mineral resource estimate, Howe conducted database verification; mineralized zones grade shell geometry, variography, and ordinary kriging grade interpolation exercises.
Mineralized zones were outlined on 25 metre spaced cross-sections and were used to create mineralized zone grade shell wireframes. When outlining mineralized zones, a cut-off grade of 1 g/tonne of gold was generally used with a minimum horizontal width of 1.5 metres.
The sample intervals were composited or regularized at 0.5 metres for the purpose of statistical analysis. The true width values were calculated using drill hole dip and azimuth values and average deposit strike and dip values. Sample values were capped at 41 g/tonne - the logarithmic mean of the samples plus two standard deviations. The top-cut was applied to regularized samples prior to calculating the intercept grade. This `cut' intercept grade was used for block grade estimation. A mean specific gravity value of 2.80 was used for the deposit based on measurements taken from 108 core samples.
A block model was created utilizing 5 metre by 10 metre by 10 metre blocks and constrained by the mineralized zone wireframes. A separate block model file was created for each zone and the grade estimation process was carried out separately for each of the zones. Ordinary block kriging was used to estimate block grades.
Based on the geological continuity, grade continuity and variography, Indicated and Inferred mineral resources were defined. All blocks within the outlined mineralized zones were included in the Inferred mineral resource category except those defined as Indicated. Blocks in the Indicated category were identified manually by outlining on cross-section, areas of the Red Zone where there was clear geological and grade continuity between intercepts. The Indicated mineral resource outline was then refined using a longitudinal section. A solid wireframe was created from the Indicated outline and was used to identify and categorize the appropriate Red Zone blocks as Indicated mineral resource. No Measured mineral resources or mineral reserves of any category were defined.
The NI 43-101 Technical Report on the Mineral Resource estimate will be filed on SEDAR within 45 days of this press release.
Quality Assurance -----------------
This mineral resource estimate incorporates all drilling completed by Wescan to date and historic drilling from the period of 1986 to 1988. In the opinion of Howe, the block model resource estimates reported herein are a reasonable representation of the global gold mineral resources found in the various zones that comprise the Jojay Deposit at the current level of sampling. Mineral resources for the Jojay Deposit are reported in accordance with the guidelines of the Canadian Securities Administrators National Instrument 43-101, and have been estimated in conformity with generally accepted CIM "Estimation and Mineral Resource and Mineral Reserve Best Practices" guidelines. The Jojay Deposit mineral resource estimate was completed by Howe's Mining Engineer,
