Pacific Ridge Exploration Ltd.: Drill Turning at Baker Basin Uranium Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 6, 2007) - Pacific Ridge Exploration Ltd. ("Pacific") (TSX VENTURE:PEX), operator of the Baker Basin Uranium Project in Nunavut has completed all prepatory work, mobilized all equipment and is now collaring the first drill hole of the 2007 season. Pacific and project partner Kaminak Gold Corporation ("Kaminak") plan a $3 million exploration program at the Baker Basin Uranium Project in 2007. A 3,000 metre Phase 1 drilling program has now been initiated. Five deep holes are planned on each of the Lucky-7 and KZ Zones to test for "structurally controlled unconformity-style" uranium mineralization. Upon completion of geophysical surveys, initial drilling of two additional new discoveries, the 7-one and Niner zones, will follow.

Initial drill testing in 2007 will focus to the Lucky-7 Zone, a prospecting discovery made during 2006, where Pacific intersected near surface structurally controlled uranium mineralization grading to 0.32% U3O8 over 3.4 metres. Drill holes at the Lucky-7 Zone are being collared to intersect the mineralized structure at depth near the basin unconformity.

The Lucky-7 Zone hosts uranium mineralization within altered and bleached Kazan sandstone associated with a northerly-trending structure. The Kazan sandstone is the major unit comprising the Baker basin in-filling sediment that rests on a conglomerate at the basin floor. Pacific completed a radiometric survey over an area measuring approximately 2 kilometres by 2 kilometres that has defined a northerly-trending radiometric anomaly measuring 500 metres in length and 100 to 200 metres in width contoured with peak values to 240 cps. The surface exposure of the Lucky-7 Zone was chip sampled across its width and yielded 0.27% U3O8 over 3.9 metres. A saw cut channel several metres away yielded 0.19% U3O8 over 3.1 metres. The average grade of 23 mineralized frost-heaved boulders assayed to 0.32% U3O8. Three angled drill holes were completed from a single set-up during 2006. The first two holes returned intercepts of 0.14% U3O8 over 1.6 metres and 0.32% U3O8 over 3.4 metres. The third hole was the deepest hole at Lucky-7; however, worsening drill conditions at depth forced this hole to be shut down before the target was reached. No significant uranium assays were obtained despite strong alteration at the bottom of the hole.

Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward looking statements include market prices, exploitation and exploration successes, and continued availability of capital and financing and general economic, market or business conditions.

Information Concerning Estimates of Mineral Resources

This news release uses the terms "inferred resources", "indicated resources", "mineral resources" and "resources". Pacific Ridge Exploration Ltd. (the "Company") advises investors that although these terms are recognized and required by Canadian securities regulations (under National Instrument 43-101 "Standards of Disclosure for Mineral Projects"), the US Securities and Exchange Commission does not recognize these terms. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, "inferred resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for a Preliminary Assessment as defined under NI 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.

The TSX Venture Exchange has not reviewed and does not accept responsibility for the adequacy or accuracy of this release.
