Pacific Ridge Intersects High-grade Copper-
Gold Mineralization in Every Drill Hole at
RDP's Day Zone Including 59.4 M of 1.68%
Copper Equivalent
Vancouver, British Columbia--(Newsfile Corp. - January 9, 2023) - Pacific Ridge Exploration Ltd. (TSXV:
PEX) (OTCQB: PEXZF) ("Pacific Ridge" or the "Company") is pleased to announce the remaining
results from the 2022 drill program completed at the RDP copper-gold project ("RDP" or the "Project"),
including drill hole RDP-22-003, which returned 59.4 m of 1.68% copper equivalent ("CuEq") from the
Day Zone. RDP is located in northcentral British Columbia, 40 km west of the Company's flagship Kliyul
copper-gold project ("Kliyul") (see Figure 1).
Pacific Ridge completed 1,860 m of drilling in six holes at RDP. Holes RDP-22-001 to RDP-22-005
were drilled at the Day Zone and RDP-22-006 at the Roy Zone (see Figure 2). The drill program was
funded by Antofagasta Minerals S.A. ("Antofagasta"), a subsidiary of Antofagasta PLC, who can earn a
75% interest in the Project by spending $10,000,000 on exploration over eight years and delivering a
preliminary economic assessment report. Last drilled in 2011, this was the Company's first ever drill
program at the Project.
Highlights of the 2022 Exploration Program
Hole RDP-22-005 intersected 107.2 m of 1.45% CuEq (0.63% Cu, 1.10 g/t Au, and 2.91 g/t Ag)
within 497.2 m of 0.68% CuEq (0.37% Cu, 0.40 g/t Au, and 1.6 g/t Ag), from surface (previously
reported, see news release dated October 25, 2022, for further information).
Hole RDP-22-003 intersected 59.4 m of 1.68% CuEq (0.78% Cu, 1.2 g/t Au, and 2.99 g/t Ag) from
surface.
Hole RDP-22-001 intersected 51.5 m of 1.01% CuEq (0.51% Cu, 0.65 g/t Au and 2.59 g/t Ag)
from surface.
The Day Zone mineralization remains open to the east, north, west, and at depth, and may be
associated with a late-mineral bounding fault on its south or southwest side.
"We are extremely pleased with the results from our first ever drill program at RDP, especially drill
hole RDP-22-005, which returned one of B.C.'s best copper intercepts last year,"
said Blaine
Monaghan, President & CEO of Pacific Ridge.
"Future drilling at RDP will be focused on expanding
the mineralized footprint at the Day Zone, which remains open in almost every direction."

Discussion of Drill Holes RDP-22-001 to RDP-22-005 at the Day Zone
Pacific Ridge completed five drill holes, totaling 1,392-metres, from a single drill pad at the Day Zone.
A
single drill pad was used for logistical reasons and to support an initial test of ideas regarding the
orientation of the surface showing following prospect scale mapping.
The Day Zone consists of a 100 x 150 m rusty weathering, malachite stained, outcrop protruding from a
boulder talus slope. Porphyry Cu-Au-Ag mineralization is hosted in a composite, hornblende-plagioclase
sub-porphyritic diorite stock that intruded polymictic volcano-sedimentary rocks of the Hazelton Group
(Telkwa Formation). Mineralization at surface is primarily chalcopyrite, with coarse blebby bornite noted
in potassic alteration zones. Chalcopyrite occurs as disseminated blebs in groundmass, as
disseminated grains on tight fractures, filling the centerline of quartz and quartz-magnetite veins (QMS
veins), or as coarse replacements up to 5x10 cm in size.
RDP-22-001
(azimuth 180°, inclination -80°) tested the Day Zone steeply to the south. Potassic altered
and mineralized diorite was intersected to 61 m depth followed by late-mineral diorite, andesite and
gabbro dykes and magnetite-chlorite altered volcaniclastic andesite host rock to 96 m. From 96-120 m,
drilling intersected a phyllic altered and pyrite mineralized sheared tuff-breccia unit and continued in
hematite-carbonate altered Telkwa Formation volcaniclastic rocks to end-of-hole. Drilling was shut down
at 240 m.
RDP-22-002
(azimuth 180°, inclination -60°) tested the Day Zone shallowly to the south. Potassically
altered, Cu-sulfide mineralized and QMS veined diorite was intersected to 48 m. From 48-95 m, a
chlorite-sericite altered late-mineral diorite with faulted contacts was encountered. The remainder of the
drill hole was in volcaniclastic andesite of the Telkwa Formation and was shut down at 138 m.
RDP-22-003
(azimuth 102°, inclination -45°) tested the continuity of the early-mineral diorite and Cu-
sulphide mineralization shallowly to the southeast. Potassically altered, Cu-sulfide mineralized and QMS
veined diorite was intersected to 73 m. The remainder of the drill hole was in late-mineral chlorite-
sericite altered diorite and was shut down at 141 m.
RDP-22-004
(azimuth 60°, inclination -45°) tested the continuity of the early-mineral diorite and
mineralization shallowly to the northeast. Potassically altered, Cu-sulfide mineralized and QMS veined
diorite was intersected to 73 m, followed by Cu-sulfide mineralization associated mainly with quartz-
carbonate veining to 276 m. From 73 m to 263 m the host rock is described as either a polymictic
breccia or breccia related to monzodiorite porphyry obscured by potassic alteration. Hematite is noted
with magnetite in the potassic assemblage after 238 m. Host volcaniclastic rocks with phyllic and
propylitic alteration overprints were intersected starting at 263 m. Drilling was shut down at 360 m.
RDP-22-005
(azimuth 60°, inclination -70°) tested the geometry of Cu-sulfide mineralized early diorite
and magmatic-hydrothermal breccia units more steeply to the northeast. See news release dated
October 25, 2022, for further information.
Modelling of drilling results suggest a generally east-west trending, steeply north-dipping porphyry Cu-Au
system that remains open to the east, north, west, and at depth (see Figures 3 and 4). The model is
preliminary at this stage and not well constrained. The system appears to be cut-off on the south or
southwest by a fault structure with late-stage dykes having exploited the same structure.

Discussion of Drill Hole RDP-22-006 at the Roy Zone
The Roy Zone is exposed on a 300 m x 200 m bench in a NE-trending composite body of coalescing
fine grained plagioclase porphyritic quartz diorite to monzodiorite stocks that intrude feldspar-phyric
volcaniclastic and polymictic basal conglomerate of the Hazelton Group (Telkwa Formation). Veins
include 0.5-5.0 cm wide, syn-mineral quartz, quartz-magnetite, and centerline chalcopyrite-filled quartz
veins, accompanied by K-feldspar alteration envelopes and patchy relict biotite. Sulfide assemblages
are dominantly chalcopyrite, chalcopyrite>pyrite and rarely bornite. Most of the mineralization-alteration
is concentrated in a WNW-trending structural corridor approximately 100 m wide.
RDP-22-006
(azimuth 190°, inclination -65°) followed up historical drill hole EQ11-01 and tested
mineralization of the mapped surface showing at depth. Intrusive units (monzodiorite and diorite) were
intersected to 323 m. A patchy potassically altered central diorite from 103 m to 309 m is flanked by
magnetite-chlorite cemented hydrothermal breccia units at its northern and southern contacts. This
diorite unit contains 10-25% irregular and dismembered QMS veins from 178 m to 292 m hosting pyrite
and lesser chalcopyrite. From 323 m, volcaniclastic host rock was encountered to end-of-hole at 468 m.
Drilling results at Roy show similar lateral zoning relationships as at the Day prospect. Cu-sulfide
mineralization with trace bornite and QMS veins occurs at near surface to 30 m, followed by
chalcopyrite>pyrite mineralization to 108 m, pyrite>chalcopyrite mineralization to 396 m, and pyrite only
to 468 m. Quartz-carbonate veins become the dominant vein type after 361 m. This is accompanied by a
general downhole decrease in Au:Cu and Au:Ag ratios. Upper-level porphyry and sub-epithermal
pathfinder elements are mostly background at Roy suggesting drilling has intersected the deep
peripheral flank of a porphyry system. Magnetic inversion modelling of historical aeromagnetic data
suggests there may be a west-dipping porphyry stock complex farther east by about 450 m, at the
margin of the large underlying magnetic feature at Roy.
About RDP
Located 40 km west of the Company's flagship Kliyul project, 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 Project
is also in a similar geological environment to NorthWest Copper's East Niv discovery, which adjoins
RDP to the north. 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.
QA/QC (Quality Assurance/Quality Control)
Pacific Ridge's 2022 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 (63.5 mm) or
NQ (47.6 mm) sawed samples from continuous intervals throughout drill holes were sealed on site and
shipped to ALS Global Laboratories' ("ALS") preparation lab in Kamloops and then to their analytical
facility in North Vancouver, BC. Fire assay and multielement analyses were completed at the ALS
analytical laboratory in North Vancouver. Drill core was crushed, pulverized and analyzed for 48 elements
using a four-acid digest followed by ICP-MS (ME-MS61) with over limits by ore grade four-acid digest
followed by ICP-AES (OG62), and with a 30 g sample analyzed for gold by fire assay and atomic
absorption finish (Au-AA23). Samples were no smaller than 50 cm and no larger than 2 m in length,
respecting changes in lithology and alteration. Blanks and commercially certified reference materials
were inserted blind into the sample stream with an overall insertion rate of 5%. Field duplicates
representing a quarter core split of the original sample are inserted at 2.5%. Pulp and crush duplicates
are inserted at 5% insertion rate by the laboratory. The QAQC results are reviewed as batches once
returned from the laboratory and appropriate actions are implemented where required. The QA/QC
results for drill holes from the 2022 drilling program at RDP are acceptable.
