Drill Results

Pacific Ridge Intersects 112.2 m of 1.35%

Copper Equivalent or 2.02 g/t Gold Equivalent

at the RDP Copper-Gold Project

Vancouver, British Columbia--(Newsfile Corp. - October 16, 2025) - Pacific Ridge Exploration Ltd.

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

announce that drill hole RDP-25-011 intersected 112.2m of 1.35% copper equivalent* ("CuEq") or 2.02

g/t gold equivalent** ("AuEq") within 405.0 m of 0.71% CuEq or 1.06 g/t AuEq from the Day target at the

Company's 100% owned RDP copper-gold project ("RDP"). RDP is located in B.C.'s Golden

Horseshoe at the southern end of the Toodoggone district, 40km west of the Company's flagship Kliyul

("Kliyul") copper-gold project (see Figure 1).

Drilling Highlights

Five drill holes, totaling 2,156 m, were completed at RDP and were focused on the Day target.

Starting near surface, drill hole RDP-25-011 returned 112.2m of 1.35% CuEq* or 2.02 g/t AuEq**

(0.76% copper, 0.86 g/t gold, and 3.16 g/t Ag) within 405.0 m of 0.71% CuEq* or 1.06 g/t AuEq**

(0.44% copper, 0.38 g/t Au and 1.87 g/t silver) at the Day target (see Table 1 and Figure 2).

This is the best CuEq intercept ever recorded at RDP, surpassing the previous best intercept of

107.2 m of 1.39% CuEq* or 2.06 g/t AuEq** (0.63% copper, 1.10 g/t gold, and 2.91 g/t silver)

within 497.2m of 0.66% CuEq* or 0.98 g/t AuEq** (0.37%Cu, 0.40 g/t Au, 1.60 g/t Ag), which was

returned in drill hole RDP-22-005 (see news release dated October 25, 2022).

The intercept in drill hole RDP-25-011 also contains three noteworthy high-grade intervals: 22.2 m

of 2.20% CuEq* or 3.29 g/t AuEq** from 4.8 m, 32.0 m of 2.06% CuEq* or 3.08 AuEq** from 85.0

m, and 19.0 m of 2.68% CuEq* or 4.01 AuEq** from 346.0 m.

Results from the remaining three drill holes, RDP-25-012,

RDP-25-013, and RDP-25-014, are

pending.

Quote

"The 2025 drill program at RDP was a huge success,"

said Blaine Monaghan President & CEO of

Pacific Ridge

. "At the beginning of the drill program, we decided upon three goals: follow up on drill

hole RDP-22-005, which returned one of B.C.'s best copper-gold intervals in 2022; confirm that the

porphyry copper-gold mineralization in RDP-22-005 is hosted in an eastward-striking, steeply

northward-dipping tabular body; and test the western magnetic lobe. The 2025 drill program at RDP

achieved all these goals. The copper equivalent intercept in drill hole RDP-25-011 was better than the

copper equivalent intercept in drill hole RDP-22-005; drill holes RDP-25-012 and RDP-25-013

confirmed the geometry of porphyry copper-gold mineralization encountered in RDP-22-005; and drill

hole RDP-25-014 confirmed that the western magnetic lobe hosts mineralization. We look forward to

reporting the remaining results."

Commodity prices:

$Cu = US$4.60/lb, $Au = US$2,600/oz., and Ag = US$30.00/oz.

There has been no metallurgical recovery testing on RDP mineralization.

The Company estimates copper recoveries (CuR) of 80%, gold recoveries (AuR) of 60%, and silver recoveries (AgR) of 60%

Factors: 22.0462 = Cu% to lbs per tonne, 0.032151 = Au g/t to troy oz per tonne, and 0.032151 = Ag g/t to troy oz per tonne.

2025 RDP Drill Program

The 2025 drill program at RDP was focused on the Day target with the objective of following up on drill

hole RDP-22-005, confirming that the porphyry Cu-Au-Ag mineralization intersected in RDP-22-005 is

hosted in an east-northeast-striking, steeply northward-dipping tabular body, and testing the western

magnetic lobe.

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

o

degrees and dip of 72

o

. A stockwork of quartz-

magnetite-chalcopyrite veins was encountered from 2.2 to 5.0m returning 2.8 m of 1.40 % CuEq* and

2.08 g/t AuEq** (0.90% Cu, 0.71 g/t Au and 3.12 g/t Ag) (Table 1) however, a late mineral intrusive was

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

RDP-25-011 was drilled from the same location at an azimuth of 48

o

degrees and dip of 65

o

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 4) hosted in early-mineral monzodiorite and

hydrothermal breccia, extending mineralization to the north of RDP-22-005 by a minimum of 35m, with

mineralization still being open to the north.

/363m length) and RDP-25-013 (160

o

/- 70

o

/582m length) were drilled from a

site 170m 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 300m 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 5 and 6), which confirmed the concept of a tabular geometry. Copper-sulphide

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

RDP-25-014, the final drill hole of the 2025 RDP drill program, was designed to test the western

magnetic lobe for copper-gold mineralization (see Figure 3). RDP-25-14 was drilled at an azimuth of

335

o

degrees and dip of 65

o

to a depth of

604m. Chalcopyrite-pyrite and chalcopyrite-bornite

mineralization occur as disseminations, and with quartz-carbonate and epidote-actinolite veins cross-

cutting potassium-feldspar and magnetite-altered monzodioritic intrusions (Figure 11).

QA/QC (Quality Assurance/Quality Control)

Pacific Ridge's 2025 exploration program was managed by Equity Exploration Consultants Ltd. of

Vancouver, B.C. The drill contractor was Dorado Drilling Ltd. of Vernon, B.C. Half-core NQ (47.6 mm)

sawed samples from continuous intervals throughout the reported drill holes were sealed on site and

shipped to ALS Global Laboratories ("ALS") preparation lab in Terrace, BC. Fire assay and

multielement analyses were completed at ALS Minerals analytical laboratory in North Vancouver. Drill

core was crushed, pulverized and analyzed for 48 elements using a four-acid dissolution followed by

ICP-MS (ME-MS61) with over limits by ore grade four-acid dissolution followed by ICP-AES (OG62),

with a 30 g sample analyzed for gold by fire assay and atomic absorption finish (Au-AA23). Blanks and

commercially certified reference materials were inserted blind into the sample stream with an overall

insertion rate of 8%. Crush duplicates are inserted at a rate of 2.5%. Pulp and crush duplicates are

inserted at 5% insertion rate by the laboratory. The QAQC results are reviewed as batches are returned

from the laboratory and appropriate actions are implemented where required. The QA/QC results for the

reported drill holes are acceptable.
