Pacific Ridge Acquires 100% Interest in Kliyul

and Redton Copper-Gold Projects

Vancouver, British Columbia--(Newsfile Corp. - May 10, 2023) - Pacific Ridge Exploration Ltd. (TSXV:

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

an agreement with AuRico Metals Inc. ("AuRico"), a wholly owned subsidiary of Centerra Gold Inc. (TSX:

CG) (NYSE: CGAU) ("Centerra"),

to acquire a 100% interest in the Kliyul and Redton copper-gold

porphyry projects (the "Projects") by issuing 16,996,099 common shares to AuRico (the "Agreement").

The Projects are located in the prolific Quesnel Trough in northcentral British Columbia (see Figure 1).

This Agreement replaces a previous agreement with AuRico whereby the Company had the right to

acquire up to a 75% interest in the Projects by spending $7.0M on exploration, issuing 3,500,000

common shares, and making cash payments totaling $160,000 by December 31, 2025 (see news

release dated January 17, 2020). The Agreement is subject to regulatory approval.

"Owning one of B.C.'s newest and most exciting discoveries outright is great news for Pacific Ridge and

its shareholders," said Blaine Monaghan, President & CEO of Pacific Ridge. "Over the last three years

we have materially increased the size of the Kliyul mineralized body to the point where we believe that

there is excellent potential to outline a sizeable copper-gold porphyry deposit. Lastly, I would like to

welcome AuRico as our newest and largest shareholder. I truly believe that today's news is an important

milestone that will help to create and unlock future value for the Company and its shareholders."

2023 Kliyul Copper-Gold Porphyry Project Exploration Plans

Pacific Ridge has budgeted approximately $4.6M for a 7,000 m diamond drill program at the Kliyul

copper-gold project ("Kliyul") this year. In addition to further expansion drilling at the Kliyul Main Zone

("KMZ"), Pacific Ridge plans to drill test several other interpreted porphyry centres that occur along a 6-

km long mineralized trend (see Figure 2). The Company will mobilize in mid-June and drilling is

expected to commence by the end of June/beginning of July.

About Kliyul

Over 60 km

2

in size, Kliyul is located 65 km southeast of the Centerra Kemess Project and close to

existing infrastructure (Figure 1). Kliyul comprises nine porphyry copper-gold target areas along two

main trends: the 1.5 km-long east-northeast Valley Fault Trend, which includes its five fault-defined target

areas (Kliyul West, KMZ, Kliyul North, East Wedge, and Kliyul East); and the 6-km-long northwest-

trending Divide Lake Fault Trend which includes Ginger, Parish Hill, Bap Ridge, and M-39 target areas

(see Figure 2).

Since 2020, Pacific Ridge has spent over $7.5M advancing Kliyul, including 8,557 m of drilling in 15

holes as well as geological, geochemical and geophysical surveys. Based on the exploration results to

date, the Company believes that there is excellent potential to define a significant porphyry copper-gold

system. Drilling at KMZ to date has defined a mineralized body measuring approximately 600 m by 350

m, and to a depth of 600 m; and geophysical data, including recent magnetic and IP surveys, suggest

that this body can be expanded significantly (see Figure 3). Highlights from Pacific Ridge's drilling are

shown in Table 1.

Drilling confirms that the MVI Induced data closely correlates with mineralization. Anomalous MVI is ~

38-hectare in size; current KMZ mineralized footprint is only 5.5 hectares, or 14.5% of the total

footprint.

About the Redton Copper-Gold Porphyry Project

Approximately 35 sq-km in size, the Redton copper-gold porphyry project ("Redton") is adjacent to

NorthWest Copper Corp's Kwanika deposit (Figure 4), which hosts 223.6 million tonnes grading 0.27%

copper, 0.25 g/t gold and 0.87 g/t silver containing 1.32 billion pounds of Cu, 1.83 million ounces of Au

and 6.27 million ounces of Ag in the Measured and Indicated category

1

. In 2022, Pacific Ridge identified

a surface geochemical target of similar size and orientation as the Kwanika Central Zone footprint,

located 4.5 km east of the Kwanika following an interpreted arc-transverse lineament.

About Pacific Ridge

Our goal is to become British Columbia's leading copper-gold exploration company. Pacific Ridge's

flagship project is the Kliyul copper-gold project, located in the Quesnel Trough, approximately 65 km

southeast of Centerra Gold Inc's Kemess Project. In addition to Kliyul, the Company's project portfolio

includes the RDP copper-gold project (optioned to Antofagasta Minerals S.A.), the Chuchi copper-gold

project, the Onjo copper-gold project, and the Redton copper-gold project, all located in British

Columbia. Pacific Ridge would like to acknowledge that its B.C. projects are located in the traditional,

ancestral and unceded territories of the Gitxsan Nation, McLeod Lake Indian Band, Nak'azdli Whut'en,

Takla Nation, and Tsay Keh Dene Nation.
