Uranium Content at Baker Increasing with Depth

August 7, 2007

Pacific Ridge Exploration Ltd. ("Pacific Ridge"), operator of the Baker Basin Uranium Project, and project partner Kaminak Gold Corporation ("Kaminak") provide an update on the Baker Basin Uranium Project. Pacific Ridge and Kaminak are pleased to report that uranium mineralization continues to depth as indicated by three drill holes completed this year at the Lucky-7 Zone. Recently received drill hole assays range to 0.20% U3O8 over 15.3 metres, including 2.74% U3O8 over 0.9 metres. In 2006 Pacific Ridge drilled 3 shallow holes at Lucky-7, the best intersection being 0.32% U3O8 over 3.4 metres at an approximate depth of 70 metres.

The Lucky-7 uranium mineralization is hosted in a vertical structure now traced from surface to a depth of 250 metres. Drilling will continue to depth in order to test continuity of the mineralized vertical structure and to determine if an "unconformity style" uranium deposit occurs where the structure intersects the basin floor. Continued drilling will also determine continuity of uranium mineralization within a 500 metre-long radiometric anomaly. The three 2007 holes completed to date, and drilled below the earlier 2006 holes, are indicating thicker and higher grade uranium intersections to depth. A summary of the assay intercepts follows:

(i) True widths are estimated at between 50% and 70% of total drill 
Drill holes L07-07-04, L07-07-05, and L07-07-06 intersected the near vertical Lucky-7 Zone at approximately 150, 200 and 250 metres, respectively, below surface with the width of mineralization and the related alteration envelope increasing with depth. From exposed mineralization at surface to a depth of 250 metres, five equally spaced drill holes have a weighted average of 6.4 metres grading 0.19% U3O8. Deeper drilling continues with hole L07-07-07 targeting the intersection of the structure and a conglomerate horizon at a depth below 300 metres. Hole L07-07-08 will test on-strike continuity of uranium mineralization.

The Lucky-7 Zone, one of 20 uranium targets within the Baker Basin Uranium Project, is emerging as a significant new discovery. This new find was discovered in 2006 by Pacific Ridge, Project Manager George Norman P. Geo, and his exploration team.

Upon completion of Lucky-7 hole L7-07-08, drilling will continue on the KZ-Zone where 5 of 6 holes drilled last year within a 1 kilometre-long radiometric anomaly, reported intersections ranging to 0.56% U3O8 over 5.5 metres.

Project Location
The Baker Basin in Nunavut, 40 kilometers from the town of Baker Lake, is adjacent to the Thelon Basin. Both basins are actively being explored for uranium.

Sample Handling
All samples collected at the Baker Basin Uranium Project are sealed in sample bags at site and forwarded in secure containers to Activation Laboratories in Ancaster, Ontario for uranium analysis. Samples are initially analyzed by a DNC technique utilizing a reactor. High values in excess of 0.5% U3O8 are then re-analyzed by XRF and titration methods. Pacific Ridge employs a QC/QA program that includes random insertion of internal duplicates and blanks into the sample stream as well as check assays by an external laboratory.

Pacific and Kaminak

Under the terms of an agreement, Pacific Ridge has the option to earn up to a 60% interest by issuing 400,000 units to Kaminak and expending $3.0 million on the project prior to December 31, 2010. Within the next few months, Pacific Ridge expects to have earned its 60% interest and to form a 60/40 joint venture with Kaminak Underlying interests for all commodities other than diamonds are held by Hunter Exploration Group as to a 2% Net Smelter Return, and by Shear Minerals Ltd./Stornoway Diamond Corporation, who collectively hold a 8.5% net profits interest.

As at June 30, 2007, Pacific Ridge Exploration Ltd. had working capital in the approximate amount of $4.9 million
