Pacific Ridge Provides Drilling Update for Kliyul and RDP Copper-Gold Projects
Pacific Ridge Provides Drilling Update for
Kliyul and RDP Copper-Gold Projects
Vancouver, British Columbia--(Newsfile Corp. - September 11, 2025) - Pacific Ridge Exploration Ltd.
(TSXV: PEX) (OTCQB: PEXZF) (FSE: PQW) ("Pacific Ridge" or the "Company") is pleased to provide
a drilling update for the Company's 100% owned Kliyul copper-gold project ("Kliyul") and RDP copper-
gold project ("RDP"), both located in B.C.'s Golden Horseshoe at the southern end of the Toodoggone
district (see Figure 1).
Drilling Highlights:
Two drill holes, totaling 1,287 m, were completed at Kliyul and were focused on infill and resource
expansion at the Kliyul Main Zone ("KMZ"), which hosts 334.1 million tonnes ("Mt") grading 0.33%
copper equivalent ("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).
Five drill holes, totaling 2,156 m, were completed at RDP and were focused on the Day target,
which returned one of B.C.'s best porphyry copper-gold intervals in 2022: Drill hole RDP-22-005
intersected 107.2 m of 1.39% CuEq* or 2.06 g/t gold equivalent ("AuEq")** (0.63% copper, 1.10
g/t gold, and 2.91 g/t silver) (see news release dated October 25, 2022)((see Figure 3).
Drilling at both Kliyul and RDP intersected strong copper mineralization (see Figures 5, 6, 8, 9, 10,
and 11).

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 approximately 130m gap in drilling north of strong copper-gold mineralization in
holes KLI-21-036 and KLI-21-038. 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 1765m to a depth of 786m. The
hole intersected chalcopyrite and bornite mineralization with quartz-magnetite veins and stockworks
(Figure 5) 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 to test for copper-gold mineralization extensions to the west
within the mineral resource estimate pit shell.
KLI-25-071 was drilled at an azimuth of 180
o
degrees and
dip of 75
o
from an elevation of 1776m to a depth of 501m.
Chalcopyrite-pyrite mineralization occurs as
disseminations with epidote-magnetite alteration, with quartz-sericite-chlorite veins, quartz-anhydrite
veins and locally, quartz-magnetite veins (Figure 6).

2025 RDP Drill Program
The 2025 drill program at RDP was focused on the Day target (see Figure 7) with the objective of
confirming that the porphyry Cu-Au-Ag mineralization intersected in RDP-22-005 is hosted in a
westward-striking, steeply northward-dipping tabular body and also to test 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-sulphide veins was encountered in the first 5m of drilling, 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 8) hosted in early-mineral monzodiorite and
hydrothermal breccia, extending mineralization to the north of RDP-22-005 by a minimum of 50m, with
mineralization still being open to the north.

RDP-25-012 (48
o
/- 65
o
/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 9 and 10), 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. 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).
