Pacific Ridge Exploration Ltd. is pleased to announce that Newmont Canada Limited, a subsidiary of Newmont Mining Corporation (NYSE & ASX:NEM; TSX:NMC), has notified Pacific Ridge that Newmont has acquired prospecting permits totaling 110,000 acres within an area of mutual interest of the Matrix Gold Project located in central Nunavut. As these permits were acquired within the boundaries of the joint venture area, Pacific Ridge has advised Newmont that it elects to accept a proportionate interest in this newly acquired ground.

Newmont has the option to earn an initial 60% interest in mineral properties comprising the Matrix Project by spending a total of C$4.0 million in staged exploration expenditures and making cash payments totaling C$400,000 to Pacific Ridge and Kaminak Gold Corporation prior to December 31, 2007. Upon earning its initial interest, Newmont may elect to form a joint venture, with Newmont owning 60%, and Pacific Ridge and Kaminak, each holding 20%. Newmont may also elect to increase its interest to 70% by spending an additional C$10 million on the project, after which a joint venture would be formed with Newmont holding 70%, and Pacific Ridge and Kaminak each holding 15%.

Pacific Ridge has been advised by Newmont that their 2005 exploration program at the Matrix Gold Project in Nunavut was successful in exploration of gold-bearing conglomerate zones, based on which an expanded 2006 exploration program, to include diamond drilling, is planned.

As previously reported by Pacific Ridge, the gold-bearing conglomerate horizons found within the Matrix Project have geological analogies to the billion-ounce Witwatersrand Basin in South Africa.
