Initial Resource Estimate for Spanish Mountain
The Spanish Mountain joint venture [Skygold Ventures Ltd. (70%) ("Skygold") (SKV-TSXV) and Wildrose Resources Ltd. (30%) ("Wildrose") (WRS- TSXV)] is pleased to announce the initial NI 43-101 compliant resource estimate for a portion of the Main Zone at the Spanish Mountain Project in central British Columbia. Independent resource estimate consultants Gary Giroux MASc, P. Eng (of Giroux Consultants Ltd) and Giles Peatfield Ph.D., P.Eng have authorized the release of this estimate. Using a cut-off grade of 0.5 g/t gold, the Main Zone is estimated to contain 1.75 million ounces of gold in the Measured and Indicated categories (67.06 million tonnes averaging 0.81 g Au/t). Current drilling has expanded the Main Zone beyond the limits of this initial resource. The map included with this release displays the extent of the Main Zone stratigraphy and the location and size of the area of drilling that forms the basis for this initial resource estimate.
The following Tables summarize the results using various cut-offs:

Brian Groves, President of the joint venture operator, Skygold Ventures, has stated: "We are extremely encouraged by the results of this initial resource estimate and with three drills active on the property, we anticipate updating this resource estimate later in 2008. We have already released results from drilling well outside of this current resource area that intersected Main Zone type grades and widths (Hole 07-DDH-670 intersected 92.5 metres of 1.0 g/t gold including 49.0 metres of 1.27 g/t gold and 12.0 metres of 1.36 g/t gold; see News Release dated March 26, 2008) and are awaiting results from holes that intersected Main Zone stratigraphy up to 500 metres from the current resource. This initial resource estimate complements other aspects of the Spanish Mountain projects such as favourable project location and infrastructure and promising preliminary metallurgical recoveries."
A high resolution version of the above map will be available at the Skygold web site: www.skygold.ca.
Scott Weekes, Skygold's VP Exploration stated: "This initial resource marks a major milestone in the exploration of the gold system at Spanish Mountain. It is important to keep in mind we have not found the limits of the Main Zone which currently, at a 0.2 g/t cutoff, hosts over 3.5 million ounces of gold at a grade of 0.445 g/t Au. This is an indication of the scale of the mineralizing system at Spanish Mountain. Our exploration program is moving forward with three drills currently active on the project and plans under way for a bulk sampling program to begin this summer."
The current resource is based on 248 diamond drill holes completed by Skygold and Wildrose from 2005 to 2007. This represents a total of 56,620 metres of drilling and 29,877 individual gold assays. Analysis of the gold grade distribution resulted in individual sample assays being capped at 26 g/t Au which affected only 9 assays. Additional factors included in the resource estimate are as follows:
- A three dimensional solid constraining the mineralization was produced from cross sections and level plans by Skygold geologists.
- Uniform 5 metre down hole composites were produced within the constraining solid. Intervals less than 2.5 metres (at the solid boundaries) were combined with adjoining intervals.
- A block model, with blocks 20 x 20 x 10 metres was superimposed over the three dimensional solid.
- 181 specific gravity measurements were taken (using the weight in air -- weight in water method) from core samples across the mineralized zone and from multiple lithologies. The resource used the average value of 2.78 with a maximum value of 3.05 and a minimum value of 2.57.
- Grade interpolation was done using ordinary kriging and search ellipses determined by variography.
The complete NI 43-101 resource report will be filed on Sedar as soon as possible.
