PACIFIC RIDGE PROVIDES EXPLORATION UPDATE FROM THE MARIPOSA GOLD PROPERTY


Pacific Ridge Exploration Ltd., during exploration at the Mariposa property, located within the Yukon’s White Gold district, has completed 34 drill holes for a total of 5,350 metres drilled so far this season. Receipt of assay results has seen delays due to high volume and continuous sample submittals as a result of increased exploration activity in the Yukon.

The objective of the 2011 drilling program is planned around completion of approximately 6,000 metres of diamond core drilling to test five gold exploration targets located within an approximate 26-square-kilometre area of the overall 262-square-kilometre Mariposa property.

The following exploration targets currently defined within the Mariposa property have seen preliminary drilling: Skookum Main — 18 holes, Skookum West — seven holes, Hackly — two holes, Gertie — three holes and Maisy-May — four holes. The Big Alex target will be drill tested next season.

Drilling is currently focused on the Skookum West area of the 3.5-kilometre-long Skookum Jim gold-in-soil trend where recent surface exploration has generated new drill targets over a two-square-kilometre area. This area lies approximately 1.5 kilometres to the southwest of the Skookum Main area, where this year’s drilling has reported results of up to 2.44 grams per tonne gold over 38.9 metres.

The Skookum Jim trend is centred along an east-northeast-trending plateau which coincides with a structural corridor that is clearly defined by disruptions and offsets of linear airborne magnetic features. The Skookum Main area lies to the north of the most prominent of these structural breaks, whereas the Skookum West straddles this break at a location where an array of northwest-, northeast- and north-south-trending structures appear to be crosscutting the main east-northeast-trending structure. Elsewhere in the White Gold district, similar structural settings are of key importance for the hosting of gold mineralization. It is also notable that north-trending structures in the Skookum West area are parallel to the prolific placer gold drainage of Scroggie Creek that flows to the north, through the western part of the Mariposa property.

In 2010, widely spaced soil sampling along 100-metre lines at Skookum West first detected gold-in-soil anomalism of up to 512 parts per billion gold, with locally elevated molybdenum values. During 2011, infill soil sampling at 25-metre stations further defined strong gold anomalism over a minimum 1,500-metre-by-800-metre area. Gold-in-soil results ranging from 20 parts per billion to a peak of 514 parts per billion appear to coincide with linear magnetic lows and/or flank magnetic highs. These features, interpreted as reflecting brittle structures and underlying mafic rock types, provide a geologic setting with potential to host gold mineralization.

Detailed prospecting and rock sampling of surface float has returned significant results within the Skookum West gold-in-soil anomaly. Of a total of 117 rock samples from a two-square-kilometre area, 27 returned results greater than 0.5 g/t gold, to a high of 19.98 g/t gold. The average grade of these results is 3.3 g/t gold. Again, as seen elsewhere in the White Gold camp, these elevated gold assays are hosted in well-silicified rocks cut by limonitic fracture nets and hematite-specularite alteration along with minor disseminated pyrite.

Some of the anomalous gold results were obtained from rock samples in areas with no indicated gold-in-soil response, but along structures interpreted from magnetic surveys. This suggests that the prospectivity of the Skookum West area may cover a larger area than indicated by the soil geochemical results. Continuing diamond drilling is therefore testing a combination of targets in the Skookum West area that include structural trends and soil and rock geochemical signatures.

It is contemplated that the drilling season will come to a close in mid-September with approximately 40 holes completed.
