Pacific Ridge Granted Option To Earn Up To 100% In Baker Uranium Project

October 1, 2007

Pacific Ridge Exploration Ltd. ("Pacific Ridge") and Kaminak Gold Corporation ("Kaminak") executed an Option, Back-In and Joint Venture Agreement (the "Agreement") dated September 28, 2007, whereby Kaminak has granted Pacific Ridge the option to increase its interest from 60% to a 100% interest in the Baker Uranium Project.

Under the terms of the Agreement, Pacific Ridge has the option to increase its interest to a 100% interest by making an initial 2.0 million share payment to Kaminak and a second 2.0 million share payment upon completion and submission to Kaminak of a positive feasibility study. Kaminak will then have the right to back-in to a 20% working interest and become a joint venture partner, by paying Pacific Ridge an amount equal to 40% of the expenditures incurred by Pacific Ridge during the period between signing the Agreement and the date Kaminak receives the positive feasibility study.

Should Kaminak elect not to exercise its back-in right, Pacific Ridge will retain its 100% interest in the Baker Uranium project.

This agreement pertains to all commodities except diamonds, and is subject to TSX-Venture exchange approval. Underlying interests are held by Hunter Exploration Group as to a 2% net smelter return interest, as well as Shear Minerals/Stornoway Diamond Corporation, who collectively hold a 8.5 % net profits interest.

The Baker Uranium project is located approximately 50 kilometres south from the town of Baker Lake, Nunavut. The Baker Basin is one of several sedimentary basins in central northern Canada that host significant uranium mineralization. Pacific Ridge is currently drill-testing strike and depth continuity of structurally hosted uranium mineralization in both the Lucky-7 and KZ Zones within the Baker Basin Project.
