Vancouver, B.C. - September 6, 2018 - Pacific Ridge Exploration Ltd. (TSX Venture: PEX) ("Pacific Ridge" or the "Company") announces that field work has been completed on its Gold Cap and RC Gold projects, Yukon.

At the 100% owned Gold Cap project in the White Gold District, Ground Truth Exploration of Dawson completed 368 deep penetrating GT Probe samples at a 5 m spacing. Ground Truth also collected 168 regular soil samples as well as geological mapping and prospecting. The work focused on two previously identified targets defined by anomalous gold in soils. The objective of the program is to define targets for drill testing. The property covers a geologic setting for White Gold style mineralization, similar to White Gold's Golden Saddle deposit, 6 km to the southwest (Indicated Mineral Resource of 961,000 gold ounces within 12,324,000 tonnes at 2.43 g/t gold and Inferred Mineral Resource of 282,500 gold ounces within 5,157,000 tonnes at 1.70 g/t gold - White Gold news release from March 5, 2018). 

At the Company's RC Gold project, work included prospecting and mapping, soil sampling and an Induced Polarization (IP) geophysical survey over four priority targets defined by the Company's 2017 program. Fox Exploration Ltd. supervised the field work and collected 118 soil samples. Aurora Geosciences carried out the IP survey which included two reconnaissance lines for a total of 4.3 km. JP Exploration Services completed a mapping and prospecting program, collecting 18 rock samples. The target at RC Gold is an Intrusion Related Gold deposit similar to Dublin Gulch, Brewery Creek and Red Mountain in Yukon and Fort Knox, True North, Pogo and Donlin Creek in Alaska. The property is road accessible, at the headwaters of Clear Creek, in the heart of the Tintina Gold Belt. 

The Company continues to await permits before it begins work on its Spius porphyry copper project. The initial program at Spius will include an IP geophysical survey, additional soil sampling and geological mapping. Previous exploration has focused on a gossan area and pyritic halo zone which surrounds the main copper target area. This 500 m by 1,000 m central zone is defined by copper values in soil ranging from 500 to 5,320 ppm, open to the south. Two recently collected float samples of porphyry style mineralization with disseminated chalcopyrite and bornite assayed 2.53% Cu and 1.43% Cu. The results of this initial program will be used to define targets for drill testing.
