Pacific Ridge Completes 2022 Drill Program at the Kliyul Copper-Gold Project; Expands Kliyul Porphyry Copper-Gold Footprint

By: Newsfile

Vancouver, British Columbia--(Newsfile Corp. - September 27, 2022) - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) ("Pacific Ridge" or the "Company") is pleased to announce that it has completed the 2022 diamond drill program at the Kliyul copper-gold porphyry project ("Kliyul" or "Project"), located in the prolific Quesnel Trough in northcentral British Columbia (see Figure 1). The Company completed 7014.7 m of drilling in 12 holes, the largest ever drill program at the Project, and successfully expanded the known Kliyul porphyry copper-gold footprint.

"Our technical team has done an outstanding job identifying and unlocking Kliyul's promise," said Blaine Monaghan, President & CEO of Pacific Ridge. "This year's results could demonstrate Kliyul's potential to host a significant copper-gold porphyry deposit."

Highlights

  • All 12 drill holes encountered porphyry copper-gold style mineralization consisting of sulphide minerals pyrite, chalcopyrite and lesser bornite;
  • Successfully expanded the known Kliyul porphyry copper-gold footprint and related hydrothermal system to approximately 1,400 m east-west by 400 m north-south; and
  • Geophysics suggest that a large, underexplored porphyry system underlies the Valley Fault Trend.

Drilling Summary

All 12 drill holes encountered porphyry copper-gold style mineralization consisting of sulphide minerals pyrite, chalcopyrite and lesser bornite (see Figure 2), in early-to transitional-stage veins and as disseminations within a kilometre-plus scale Late Triassic/Early Jurassic paleo-hydrothermal system centered on a multi-stage diorite porphyry intrusive dyke/plug complex. Step-out drilling to the south, west, east, and north of the Kliyul Main Zone ("KMZ") successfully expanded the known Kliyul porphyry copper-gold footprint and related hydrothermal system to approximately 1,400 m east-west by 400 m north-south, following the east-northeast trending Valley Fault, and obliquely crossing Valley Fault to the north (see Figures 3 and 4).

In addition to KMZ, four additional zones, interpreted as separate fault blocks, have been defined along the Valley Fault Trend. KMZ is considered the highest standing block surrounded by downthrown blocks with good deposit preservation potential. From west to east these include Kliyul West, East Wedge, Kliyul East, and Kliyul North.

These fault block zones lie within a broad coincident geophysical anomaly that was more clearly defined with a high-resolution helicopter-borne magnetic gradient, radiometric, and VLF-EM survey completed by Precision GeoSurveys Inc. in 2022, comprising 423 line-kilometers flown at 75 m line-spacing. The combined Kliyul geophysical anomaly now includes an approximately 1,200 x 800 m east-northeast trending ring-shaped K/eTh radiometric anomaly; an approximate 800 x 500 m high magnetic anomaly underlying KMZ and parts of Kliyul West and East Wedge; an outer moderate magnetic anomaly greater than one 1-km in diameter; and an arc-shaped combined high chargeability and moderate-high resistivity anomaly that spans the Kliyul system across all four zones (see Figures 5 and 6). The magnetic, chargeability and resistivity anomalies are open at depth below 360 m. Combined, the geophysics suggest that a large, underexplored porphyry system underlies the Valley Fault Trend.

In addition to the drill program in the KMZ area, Pacific Ridge advanced several other interpreted porphyry centres that occur along an under-explored 4 km long northwest-trending corridor of quartz-sericite-pyrite (phyllic) alteration. The Company completed a 27 line-kilometre Induced Polarization (IP) survey at 200 m spacing across the Ginger zone, Parish Hill/Bap Ridge zone, and M-39 zone (see Figure 7). Pacific Ridge also conducted a mapping and rock geochemical sampling program over the same areas. The Company plans to drill-test several of these targets in 2023.

Initial drill results from the 2022 drill program are expected in October.

About Kliyul

Over 60 km2 in size, Kliyul is a copper-gold porphyry project located 50 km southeast of Centerra Gold Inc. ("Centerra") (TSX: CG) (NYSE: CGAU) Kemess Mine and close to existing infrastructure. Kliyul hosts five porphyry targets: KMZ, Bap Ridge, Ginger, M39, and Paprika. Each representing an interpreted porphyry centre over an underexplored 4 km long northwest-trending corridor of quartz-sericite-pyrite (phyllic) alteration.

The KMZ is the most intensely explored area, with 36 drill holes (6,608 m) drilled prior to Pacific Ridge's 2022 drill program. Most of this drilling targeted near-surface copper-gold mineralization. The results of the Company's 2021 Kliyul drill campaign are shown in Table 1.

Recovery is assumed to be 100% - there has been no metallurgical testing on Kliyul mineralization.

Porphyry copper mineralization at Kliyul typically comprises both veined and disseminated chalcopyrite with lesser amounts of bornite. Vein-hosted mineralization is within epidote-chalcopyrite±anhydrite±bornite veins, anhydrite-quartz-chalcopyrite±magnetite veins, chalcopyrite veins, and quartz-chlorite-magnetite-chalcopyrite±bornite veins. Epidote-chalcopyrite±anhydrite±bornite veins are the most common vein type and have varied vein selvages including chlorite, albite or sericite. Mineralization is most commonly hosted by andesite and volcaniclastic andesite, although feldspar porphyry and equigranular diorite can also be hosts. Increased copper and gold grades occur within strong magnetite alteration and with increased vein density. The presence of bornite is associated with higher copper and gold grades.

Pacific Ridge can acquire up to a 75% interest in Kliyul and Redton from Aurico Metals Inc., a wholly owned subsidiary of Centerra, by making cash payments totaling $160,000, issuing 3.5 million shares, and spending $7.0 million on exploration by December 31, 2025 (see news release dated January 17, 2020). The Company expects to have made the required exploration expenditures to earn the 75% interest in Kliyul and Redton this year.
