Drilling Update at Pacific Ridge's RDP Copper- Gold Project

Exploration Programs

Drilling Update at Pacific Ridge's RDP Copper-

Gold Project

Vancouver, British Columbia--(Newsfile Corp. - August 25, 2025) - Pacific Ridge Exploration Ltd.

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

provide an update on the drill program underway at the Company's 100% owned RDP copper-gold

project ("RDP" or the "Project"), located in B.C.'s Golden Horseshoe at the southern end of the

Toodoggone district and 40 km west of the Company's flagship Kliyul copper-gold project (see Figure

1).

Drilling at RDP in 2022 returned one of B.C.'s best porphyry copper-gold intervals that year. Drill hole

RDP-22-005 intersected 107.2 m of 1.39% copper equivalent* ("CuEq") or 2.06 g/t gold equivalent**

("AuEq") (0.63% copper, 1.10 g/t gold, and 2.91 g/t silver) within 497.2 m of 0.66% CuEq* or 0.97 g/t

AuEq** (0.37% copper, 0.40 g/t gold, and 1.60 g/t silver) at the Day target (see news release dated

October 25, 2022) (see Figure 2).

"We are very pleased with what we are seeing so far,"

said Blaine Monaghan, President & CEO of

Pacific Ridge.

"Strong copper mineralization is present in many of the drill holes and drilling has

confirmed that the porphyry copper-gold-silver mineralization at Day is hosted in a tabular body that

remains open. We look forward to reporting the drill results from the 2025 RDP drill program."

2025 RDP Drill Program

The 2025 drill program at RDP is focused on the Day target with the objective of confirming that the

porphyry Cu-Au-Ag mineralization at Day is hosted in a westward-striking, steeply northward-dipping

tabular body.

RDP-25-010, the first drill hole of the 2025 exploration program, was located 40 m southwest of RDP-

22-005. RDP-25-010 was drilled at an azimuth of 60° degrees and dip of 72°.

A stockwork of quartz-

magnetite-sulphide veins was encountered in the first 5 m of drilling, however, a late mineral intrusive

was intersected from 5 m to 175.5 m and the hole was terminated.

RDP-25-011 was drilled from the same location at an azimuth of 48° degrees and dip of 65° to a depth

of 431 m and cut underneath and to the northwest of RDP-22-005. Patchy potassic alteration (k-feldspar-

magnetite)

was intersected as well as intervals of strong quartz-magnetite sulphide veining,

chalcopyrite+/- bornite mineralization (see Figure 3) hosted in early-mineral monzodiorite and

hydrothermal breccia, extending mineralization to the north of RDP-22-005 by a minimum of 50 m, with

mineralization still being open to the north.

RDP-25-012 (48° /- 65

°

/363 m length) and RDP-25-013 (160° /- 70° /582 m length) were drilled from a

site 170 m northeast of RDP-22-005 to test the interpreted tabular porphyry Cu-Au mineralization

geometry between RDP-22-005 and RDP-23-007, which was collared 300 m NE of RDP-22-005 and

ended in 19.0 m of 0.45% CuEq* or 0.67 g/t AuEq** (0.32% copper, 0.19 g/t gold, and 1.08 g/t silver)

(see new release dated November 23, 2023).

Chalcopyrite and bornite mineralization hosted in early-

mineral, potassically-altered monzodiorite intrusive rocks and hydrothermal breccia were intersected

(see Figures 4 and 5), which confirmed the concept of a tabular geometry. Copper-sulphide

mineralization was intersected to a vertical depth of 500 m in RDP-25-013 and it remains open.

RDP-25-014, ongoing, is being drilled at an azimuth of 160° degrees and dip of 70° from the same drill

pad as RDP-25-011.

About Pacific Ridge

A Fiore Group company, Pacific Ridge's goal is to become British Columbia's leading copper

exploration company. The Kliyul copper-gold project, located in the prolific Quesnel terrane close to

existing infrastructure, is the Company's flagship project. In addition to Kliyul, Pacific Ridge's project

portfolio includes the RDP copper-gold project, the Chuchi copper-gold project, the Onjo copper-gold

project, and the Redton copper-gold project, all located in B.C. The Company would like to acknowledge

that its B.C. projects are 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.

**AuEq = ((Au(g/t) x $Au x 0.032151) + ((Cu%) x CuR/AuR x $Cu x 22.0462) + (Ag(g/t) x AgR/CuR x $Ag x 0.032151)) / ($Au x 0.032151).

Commodity prices:

$Cu = US$3.25/lb, $Au = US$1,800/oz., and Ag = US$20.00/oz.

There has been no metallurgical testing on RDP mineralization.

The Company estimates copper recoveries (CuR) of 84%, gold recoveries (AuR) of 70%, and silver recoveries (AgR) of 65% based on average
