Drilling Underway at Pacific Ridge's RDP

Copper-gold Project

Vancouver, British Columbia--(Newsfile Corp. - August 28, 2023) - Pacific Ridge Exploration Ltd.

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

is underway at the RDP copper-gold project ("RDP" or the "Project"), located in northcentral British

Columbia, 40 km west of the Company's flagship Kliyul copper-gold project ("Kliyul") (see Figure 1).

Antofagasta Minerals S.A., a wholly owned subsidiary of Antofagasta PLC (LSE: ANTO), 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 news release dated February 8, 2022). Pacific Ridge is

the operator and is supporting the RDP exploration program from Kliyul camp.

2023 RDP Exploration Program update

The Company has completed one drill hole (RDP-23-07) of the planned 1,800 m diamond drill program

so far. RDP-23-07 is a 300 m eastern step out from drill hole RDP-22-005, which intersected 107.2 m of

1.45% CuEq

1

(0.63% Cu, 1.10 g/t Au, and 2.91 g/t Ag) within 497.2 m of 0.68% CuEq

1

(0.37% Cu, 0.40

g/t Au, and 1.6 g/t Ag) at the Day Target in 2022 (see Figures 2 and 3).

The surface geochemical grid sampling (rocks and soils) and Induced Polarization (IP) geophysical

survey program is complete and focused on the Bird and Porcupine targets; an IP geophysical survey

was also completed over Day. In total, 45 rock samples were collected over an 800 x 600 m area at

Porcupine, 345 soil samples collected at 50 m spacing in 12 lines (100 m line-spacing) at Bird and

Porcupine, five IP survey lines (9.2 line-kilometres) completed over Bird and Porcupine, and three IP

survey lines (4.4 line-kilometres) completed over Day (see Figure 3).

About RDP

Located 40 km west of the Company's flagship Kliyul, RDP is greater than 10,000 hectares in size and

lies within the Stikine Terrane, which is host to numerous significant porphyry deposits in northern British

Columbia, including Kemess, Red Chris, Kerr-Sulphurets and Galore Creek. The eastern margin of

Stikine Terrane in this part of northcentral BC has been underexplored historically and has seen

increased exploration activity since its coverage in the 2017 Geoscience BC Search Phase III airborne

magnetic and radiometric survey.

RDP contains several porphyry copper-gold targets (Roy, Day, Porcupine, and Bird) that have been

explored intermittently since the early 1970's, including prospecting and mapping, various geochemical

surveys, ground- and airborne geophysical surveys, trenching and a limited amount of drilling. The

Project is underlain by lower Hazelton Group volcanic and sedimentary rocks (Lower Jurassic) of

andesitic and dacitic composition and the Gyr rhyolite porphyry; and by Late Triassic to Early Jurassic

plutonic rocks including the Fir gabbro and Roy plutonic suite with porphyritic plugs, sills, and stocks of

monzodiorite composition.

About Pacific Ridge

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

flagship project is its 100% owned Kliyul copper-gold project, located in the Quesnel Trough 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.
