at Kliyul Copper-Gold Project; Expands

Vancouver, British Columbia--(Newsfile Corp. - November 18, 2025) - Pacific Ridge Exploration Ltd.
(TSXV: PEX) (OTCQB: PEXZF) (FSE: PQW) ("Pacific Ridge" or the "Company") is pleased to
announce that drill hole KLI-25-070 intersected 289.0 m of 0.77% copper-equivalent* ("CuEq") or 1.15
grams per tonne ("g/t") gold equivalent** ("AuEq") at the Company's 100% owned Kliyul copper-gold
project ("Kliyul" or the "Project") located in the prolific Quesnel terrane in Northcentral B.C
(see Figure 1).
Drilling Highlights:
Pacific Ridge completed two drill holes, totaling 1,287 m, at Kliyul in 2025 which were focused on
infill and resource expansion at the Kliyul Main Zone ("KMZ"). KMZ hosts 334.1 million tonnes
("Mt") grading 0.33% CuEq*(0.15% copper, 0.26 g/t gold, and 0.95 g/t silver) in the Inferred
Mineral Resource category (see news release dated August 6, 2025) (see Figure 2).
Drill hole KLI-25-070 returned 289.0 m of 0.77% CuEq* or 1.15 g/t AuEq** (0.26% copper, 0.75 g/t
gold, and 1.54 g/t silver) within 489.8 m of 0.56% CuEq* or 0.84 g/t AuEq** (0.20% copper, 0.53
g/t gold and 1.34 g/t silver) (see Table 1) (see Figure 3).
Drill hole KLI-25-071 returned 91.0 m of 0.47% CuEq* or 0.70 g/t AuEq** (0.23% copper, 0.35 g/t
gold, and 0.93 g/t silver) within 421 m of 0.24 CuEq* or 0.35 g/t AuEq** (0.12% copper, 0.16 g/t
gold, and 0.62 g/t silver) (see Table 1) (see Figure 3).
Drill hole KLI-25-070 is one of the best holes ever drilled at KMZ and filled a 130 m gap between
drill holes. It has a high gold g/t: copper % ratio (>2) and is similar in style to drill hole KLI-21-036,
which intersected 437 m of 0.64% CuEq* or 0.96 g/t AuEq* (0.22% copper, 0.60 g/t gold and 1.62
g/t silver), and drill hole KLI-21-037 which intersected 566.7 m of 0.51% CuEq* or 0.76 g/t AuEq**
(0.20 % copper, 0.44 g/t gold, and 1.39 g/t silver) (see news releases dated December 1, 2021,
and January 22, 2022, respectively) (see Figures 4 and 5). Further, it confirmed the presence of a
high-grade copper gold mineralized northward-dipping pipe-shaped zone that continues north of
the Valley Fault (Figure 4).
Drill hole KLI-25-071 extended copper-gold mineralization 110 m further west of drill hole KLI-23-
068, which intersected
455.8 m of 0.43% CuEq* and 0.64 g/t AuEq** (0.17% copper, 0.27 g/t
gold, and 0.93 g/t silver) (see news release dated January 9, 2024), and successfully expanded
mineralization within the current mineral resource pit shell (see Figure 5).
"The 2025 drill program at Kliyul, focused on infill and resource expansion at KMZ, was a big
success,"
said Blaine Monaghan, President & CEO of Pacific Ridge
. "Drill hole KLI-25-070 returned
one of the best intervals ever recorded at KMZ and drill hole KLI-25-071 extended copper-gold
mineralization 110 m to the west. The 2026 drill program at Kliyul will focus on continued resource
expansion drilling at KMZ and testing a number of drill targets that occur along an under explored 6-
km mineralized trend."

2025 Kliyul Drill Program
The 2025 drill program at Kliyul was focused on infill and resource expansion at KMZ.
KLI-25-070, the first drill hole of the program, was collared south of the Valley Fault (Figure 4) and was
designed to test an approximate 130 m gap in drilling north of strong copper-gold mineralization in holes
KLI-21-036, which intersected 437 m of 0.64% CuEq* or 0.96 g/t AuEq* (0.22% copper, 0.60 g/t gold
and 1.62 g/t silver) (see news release dated December 1, 2021) and KLI-21-037, which intersected
566.7 m of 0.51% CuEq* or 0.76 g/t AuEq** (0.20 % copper, 0.44 g/t gold, and 1.39 g/t silver) (see news
release dated January 22, 2022). KLI-25-070 was collared from the same location as KLI-21-036 and
drilled at an azimuth of 354
o
degrees and dip of 80
o
from an elevation of 1765 m to a depth of 786 m.
The hole intersected chalcopyrite and bornite mineralization with quartz-magnetite veins and stockworks
(Figure 6) and as disseminations, as well as chalcopyrite +/-bornite and pyrite mineralization associated
with epidote and anhydrite veins.
KLI-25-071 was collared west of KLI-23-068, which intersected
455.8 m of 0.43% CuEq* and 0.64 g/t
AuEq**, and was designed to test for copper-gold mineralization extensions to the west within the
mineral resource estimate pit shell at an azimuth of 180
o
degrees and dip of 75
o
from an elevation of
177 6m to a depth of 501 m.
Chalcopyrite-pyrite mineralization occurs as disseminations with epidote-
magnetite alteration, with quartz-sericite-chlorite veins, quartz-anhydrite veins and locally, quartz-
magnetite veins (Figure 7).

Future Exploration at Kliyul
In addition to continued resource expansion drilling at KMZ, Pacific Ridge also plans to test a number of
drill targets that occur along an underexplored 6-km mineralized trend, which include, from south to north,
M39, Bap Ridge, Parish Hill, Ginger South and Ginger (see Figure 2). Further, the Company also plans
on drill testing the Klip target, which is a new target identified in a 2024 ZTEM survey (see Figure 8). The
Klip target is located north of KMZ and is named after a historical BC MINFILE occurrence (094D 185),
the Klip Occurrence, located 400 m to the west. The Klip Occurrence records a NE-striking shear zone
within QSP-altered volcaniclastic rocks. A one metre chip sample taken across the shear zone in 1985
yielded 3.8 g/t gold and 5.3 g/t silver. Pacific Ridge believes that drilling to date has only tested one part
of the porphyry system and that most of the system remains hidden and untested to the north.

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 HQ (63.5mm) or
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 1 per 40 samples. Alternating pulp and crush duplicates are inserted at a rate of 1 in 20
samples. 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.
