Vancouver, British Columbia--(Newsfile Corp. - July 23, 2024) - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) (FSE: PQWN) ("Pacific Ridge" or the "Company") is pleased to announce that a helicopter-borne Z-Axis Tipper Electromagnetic ("ZTEM") geophysical survey is underway at its 100% owned flagship Kliyul copper-gold project ("Kliyul"). In addition to the ZTEM survey at Kliyul, the Company is also planning an induced polarization ("IP") geophysical survey at its 100% owned Redton copper-gold project ("Redton"), and a 2,500 - 3,500 m diamond drill program at the Chuchi copper-gold project ("Chuchi") this summer. Kliyul, Redton, and Chuchi are located in the prolific Quesnel terrane in northcentral British Columbia (see Figure 1).
"I'm very excited about the ZTEM survey underway at Kliyul," said Blaine Monaghan, President and CEO of Pacific Ridge. "Results of the 2023 drill program provided us with new vectors for targeting higher-grade copper-gold porphyry mineralization and possibly the source intrusion at the Kliyul Main Zone. I am confident that we will be able to increase the grade profile and the mineralized extents of the Kliyul Main Zone if the ZTEM survey results confirm our understanding."
ZTEM Survey at Kliyul
The ZTEM survey at Kliyul will comprise 599 line-kilometres, covering approximately 85% of Kliyul, and will include the BAP Ridge, Ginger, Ginger South, Kliyul Main Zone ("KMZ"), M-39, and Parish Hill target areas. The ZTEM survey will also cover a portion of the mineral claims acquired in 2023 (see Figure 2). Although Kliyul presently lacks deep view geophysics, a 3D remanent magnetic inversion model developed by Platform Geoscience in 2020 suggests there is an underlying stock and source pluton starting at a depth of approximately 600 m (See Figure 3). The 2024 ZTEM survey and inversion modelling will provide Pacific Ridge with 3D geophysical coverage to over one kilometre depth. This will enable the Company to develop a signature of porphyry copper-gold mineralization to:
Expand KMZ laterally and to depth;
Evaluate the KMZ area for a cluster or linear series of porphyry targets;
Refine other existing porphyry targets including Bap Ridge, Ginger, Ginger South, M-39, and Parish Hill; and
Identify new porphyry targets on recently acquired mineral claims.

ZTEM Survey to Support 2023 Kliyul Drill Results
A total of 10,284 m of diamond drilling was completed in 2023, the largest ever drill program at Kliyul, and tested an area measuring 1,300 m E-W x 600 m N-S x 650 m depth. Drilling materially increased the known extents of porphyry mineralization at KMZ to 760 m E-W x 600 m N-S x 650 m depth.
Based on the 2023 drilling results, KMZ has been modelled as a symmetrically zoned porphyry system with a magnetite-chlorite ± biotite altered and chalcopyrite ± bornite mineralized porphyry core (~250 m diameter) that plunges steeply to the north-northeast from KMZ into KMZ North across a central healed fault or structural zone (see Figure 3). Mineralization (>0.4% CuEq1) is controlled by a steeply plunging stem/pipe feature, as well as by gently dipping stratigraphic and permeability controls in host rock.
The last drill hole of 2023 (KLI-23-069) intersected over 170 m of quartz diorite and feldspar porphyry intrusive phases starting at 483.0 m in KMZ North, possibly representing a central composite stock intrusion. Drilling returned 45.0 m of 0.58% copper equivalent ("CuEq")1 or 0.86 g/t gold equivalent ("AuEq")2 (0.38% copper, 0.28 g/t gold, and 2.20 g/t silver) at a downhole depth of 584 m and was terminated in mineralization at 655 m (see news release dated January 9, 2024). This is the deepest mineralized interval encountered at Kliyul and the Company believes it provides a vector towards a higher-grade porphyry centre (see Figure 3 and 4). In addition, a 3D Magnetic Vector Inversion (MVI) footprint developed by Fathom Geophysics suggests that there are several untested targets, mainly in KMZ North and KMZ West (see Figure 4).
The 2024 ZTEM survey will allow for the creation of a 3D ZTEM and Magnetic Inversion model. If the model confirms the Company's interpretation of the KMZ porphyry system, a central causative stock ~600 m deep in KMZ North and KMZ is a suprajacent dyke and fracture array ± breccia complex, it will greatly increase the prospectivity of the untested areas in the MVI footprint and open up the KMZ porphyry system for significant expansion.

About Kliyul
Owned 100% by Pacific Ridge, Kliyul is over 90 km2 in size and is located in the prolific Quesnel terrane close to existing infrastructure. Kliyul hosts several compelling exploration targets within a six-kilometre long mineralized trend, including KMZ, which has been the Company's focus since 2020. Pacific Ridge has completed more than 17,500 m of diamond drilling at KMZ and has expanded the known mineralized extents to 760 m east-west, up to 600 m north-south, and up to 650 m vertical. KMZ remains open in every direction and at depth. Drill highlights include drill hole KLI-21-037 which returned 316.7 m of 0.79% CuEq1 or 1.17 g/t AuEq2 (0.30% copper, 0.70 g/t gold, and 2.17 g/t silver) within 566.7 m of 0.51% CuEq1 or 0.75 g/t AuEq2 (0.20% copper, 0.44 g/t gold, and 1.31 g/t silver) (see news release dated January 31, 2022).
