Vancouver, British Columbia--(Newsfile Corp. - June 18, 2020) - Pacific Ridge Exploration Ltd. (TSXV: PEX) ("Pacific Ridge" or the "Company") reports that it has completed a reinterpretation of historical geophysical surveys, including several campaigns of ground magnetics and induced polarization ("IP") surveys and an airborne magnetic survey completed by Geoscience BC over its Kliyul Au-Cu porphyry prospect, north-central BC. This interpretation has been integrated with known surface geology, alteration and mineralization as well as data from 19 drill holes to produce a 3-D target model. The geophysical interpretation was completed by Platform Geoscience of Toronto. The Kliyul property is located 200 km north of Smithers and 70 km south of the Kemess mine, within 5 km of the Omineca Mine Road (Figure 1).

The geophysical study demonstrated that mineralization is associated with a wide range of chargeabilities and resistivities, but it is typically associated with the transition between moderate to low chargeabilities and moderate resistivity. Most of the mineralized intersections are either within or adjacent to areas of magnetic highs, although the correlation between Au-Cu and magnetite does not always hold. In some mineralized intervals alteration overprinting has destroyed hydrothermal magnetite, and in others, magnetite is not part of the mineral assemblage or is weak. The mineralization footprint has the potential to be expanded beyond the magnetic anomalies. The study has shown that the main Kliyul zone is open laterally, particularly to the north and to depth. It has also shown the potential for new discoveries, in particular at BAP Ridge, the M39 Zone and Ginger, all of which demonstrate similar geophysical targets (see Figure 2).

The table below shows highlights from historical drilling at the main Kliyul Zone. Drill hole collar locations are shown in Figure 3 and an east-west section through the Kliyul zone is shown in Figure 4.

*interval to end of hole
CuEQ = ((Cu(%) x CuP x 22.0642) + (Au(gpt) x AuP x 0.032151)) / (CuP x 22.0642)
AuEQ = ((Cu(%) x CuP x 22.0642) + (Au(gpt) x AuP x 0.032151)) / (AuP x 0.032515)
CuP = US$2.35/lb.                             AuP = US$1,700/oz.

The planned 2020 field program will include additional IP surveying, to extend the depth of investigation at the Kliyul Zone from 250 m to over 400 m and to extend the survey coverage to the south over BAP Ridge and the M39 Zone. The purpose of this program is to refine targets for a planned 2021 drill campaign. Permit applications have been submitted for this work.
