Pacific Ridge Completes over 11,700 M of

Diamond Drilling at Kliyul and RDP Copper-

Gold Projects

Vancouver, British Columbia--(Newsfile Corp. - September 21, 2023) - Pacific Ridge Exploration Ltd.

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

Company completed 10,284 m of diamond drilling at its 100% owned Kliyul copper-gold project

("Kliyul") and 1,428 m at the RDP copper-gold project ("RDP"). Kliyul is located in the prolific Quesnel

Terrane, close to existing infrastructure, and RDP is located 40 km to the west of Kliyul in the Stikine

Terrane (see Figure 1).

Kliyul Highlights

10,284 m of diamond drilling was completed in 19 drill holes at Kliyul, making the 2023 exploration

program the largest ever on the Project.

8,965 m in 16 drill holes in six contiguous fault block zones of the Kliyul porphyry copper-gold

complex tested an area measuring approximately 1,300 m east-west, 600 m north-south, and up to

650 m vertical depth (see Figure 2).

1,319 m in three drill holes tested three interpreted porphyry centres (Ginger, Ginger South, and

Parish Hill) up to 1.5 km from the Kliyul Main Zone ("KMZ") (see Figure 3).

Pacific Ridge has reported assay results from the first four diamond drill holes with hole KLI-23-

054 returning 305.5 m of 0.23% copper, 0.51 g/t gold, and 1.22 g/t silver within 540.3 m of 0.19%

copper, 0.36 g/t gold, and 1.09 g/t silver (see news release dated August 23, 2023). The results

from the remaining 15 drill holes completed at Kliyul will be released once assays are received

and compiled.

RDP Highlights

1,428 m of diamond drilling was completed in three drill holes at RDP.

987 m in two broad step-out holes (over 300 m each) from drill hole RDP-22-005, which returned

107.2 m of 0.63% copper, 1.10 g/t gold, and 2.91 g/t silver within 497.2 m of 0.37% copper, 0.40

g/t gold, and 1.6 g/t silver at the Day Target in 2022 (see news release dated October 25, 2022)

(see Figure 4).

441 m in one drill hole completed at the Bird target where the Company discovered porphyry

copper-gold mineralization in an outcrop exposed in a stream cutbank in 2022.

The results from the three drill holes completed at RDP will be released once assays are received

and compiled.

"2023 was Pacific Ridge's busiest exploration season ever,"

said Blaine Monaghan, President & CEO

of Pacific Ridge.

"I'm very confident that we will continue to grow the known extents of the Kliyul

porphyry copper-gold complex. I also look forward to the drill results from RDP where 2022 drilling

returned one of the best reported porphyry intercepts in B.C. last year."

2023 Kliyul Drilling Program Update

The 2023 Kliyul drilling program was completed on September 14

th

with the termination of drill hole KLI-

23-069 at 655 m (55 m beyond planned depth). Seasonal progressive reclamation and exploration

camp demobilization is underway. The total of 10,284 m of diamond drilling at Kliyul followed the

decision to reallocate 2,000 m of drilling originally planned for the Company's Chuchi copper-gold

project (see Pacific Ridge news release dated July 25, 2023) increasing the planned 2023 drilling at

Kliyul from 7,000 m to 9,000 m. An additional 1,284 m of drilling was due to operational efficiencies. The

10,284 m diamond drilling program is the largest ever seasonal drilling program to be completed at

Kliyul.

The objectives of the 2023 Kliyul exploration drilling program were to expand the known extents of the

Kliyul porphyry copper-gold complex and to test several high-priority interpreted porphyry centres

occurring along the Divide Lake Fault and Valley Fault corridors (see Figure 3).

2023 RDP Drilling Program Update

The 2023 RDP drilling program was completed on September 2

nd

with termination of drill hole RDP-23-

009 at 441 m. Drill rig demobilization and seasonal progressive reclamation have been completed. A

total of 1,428 m of diamond drilling was completed in three drill holes and tested two porphyry copper-

gold prospects, Day and Bird (see Figure 4).

The 2023 drill program at RDP was funded by Antofagasta Minerals S.A. ("Antofagasta"), a wholly

owned subsidiary of Antofagasta PLC (LSE: ANTO). Antofagasta can earn a 75% interest in RDP by

spending $10,000,000 on exploration over eight years and delivering a preliminary economic

assessment report (see Pacific Ridge news release dated February 8, 2022). Pacific Ridge is the

operator and supported the RDP exploration program from Kliyul camp, located 40 km to the east.

About Pacific Ridge

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

flagship asset is its 100% owned Kliyul copper-gold project, located in the prolific Quesnel Terrane close

to existing infrastructure. 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.
