Pacific Ridge Completes ZTEM Airborne

Geophysical Surveys at Chuchi and Onjo

Copper-Gold Porphyry Projects; Precious

Metals Summit Beaver Creek

Vancouver, British Columbia--(Newsfile Corp. - August 16, 2022) - Pacific Ridge Exploration Ltd.

(TSXV: PEX) (OTCQB: PEXZF) ("Pacific Ridge" or the "Company") is pleased to announce that it has

completed ZTEM airborne geophysical surveys at the Chuchi

and Onjo copper-gold porphyry projects

located to the west of Centerra Gold Inc.'s ("Centerra") (TSX: CG) (NYSE: CGAU) Mount Milligan mine in

northcentral B.C. (please see Figure 1).

The geophysical surveys at Chuchi and Onjo (720 line-km at Chuchi and 667 line-km at Onjo) will be

followed by exploration programs including geological mapping, rock and soil sampling, and re-logging

historical drill core. Pacific Ridge will further investigate existing targets and new targets, expected to be

generated by the ZTEM surveys, with the ultimate goal of defining future drill targets.

"Although the Kliyul copper-gold porphyry project is our focus, we believe that both Chuchi and Onjo have

the potential to host significant porphyry deposits," said Blaine Monahan, President & CEO of Pacific

Ridge. "The exploration programs at Chuchi and Onjo are fully funded and the results will help us to

define targets for future drilling."

ZTEM is a modern geophysical technique utilizing natural earth currents to image the subsurface three-

dimensional distribution of apparent resistivity to depths exceeding one kilometer. ZTEM has proven to

be effective in outlining the large hydrothermal mineralization and alteration systems associated with

porphyry deposits that are often kilometer plus scale horizontally and vertically, and it is particularly useful

in defining the structures that are often important in localizing or offsetting mineralization. This early-stage

airborne remote sensing technique has never been applied to Chuchi or Onjo and will provide a new

perspective that will help

to guide future exploration.

Chuchi

Pacific Ridge recently acquired an option to earn up to a 75% interest in Chuchi from AuRico Metals Inc.

(see news release dated

May 9, 2022

). Over 6,100 ha in size, Chuchi hosts a large, well-mineralized

gold-rich porphyry copper system, where many of the historical drill holes bottomed in mineralization. The

main BP Zone is less than two kilometers outboard of the southeastern margin of the regional Hogem

batholith and is defined by a 4 km x 3 km halo of outer propylitic alteration surrounding a central 1.5 km x

1.5 km area of copper-gold mineralization, which is open to depth and potentially to the east across the

north-south trending Valley Fault (see Figure 2). Grades within the mineralized portion of the BP Zone

range from 0.21% to 0.40% Cu and from 0.21 g/t to 0.44 g/t Au (see Table 1).

Onjo

As announced on February 3, 2022, Pacific Ridge acquired a 100% interest in the 9,700 ha Onjo

project, located 15 km west of Centerra's Mount Milligan Mine (see Figure 3). Onjo hosts skarn and

alkalic porphyry copper-gold mineralization associated with monzonitic phases of the Witch Lake

intrusions cutting Takla volcanic rocks, similar to the mineralization and host rocks at Mount Milligan. The

style of copper-gold mineralization returned in historical drilling, combined with the presence of nearby

skarn occurrences, suggests that this is the upper levels of an alkalic porphyry system. The Company

believes that Onjo has the potential to host an alkalic porphyry copper-gold deposit at depth.
