Vancouver, Jan 31, 2022 - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) ("Pacific Ridge" or the "Company") is pleased to announce assay results from drill hole KLI-21-037, the second of three diamond drill holes completed during the 2021 drilling campaign at the Company's Kliyul porphyry copper-gold project ("Kliyul" or "Project"), located in the prolific Quesnel Trough in Northwest British Columbia (see Figure 1).
Drill hole KLI-21-037 highlights:
- 566.7 m of 0.48% copper equivalent (CuEq) or 0.76 gpt (grams per tonne) gold equivalent (AuEq), comprising 0.20% Cu and 0.44 gpt Au.
- Includes 316.7 m of 0.75% CuEq or 1.17 gpt AuEq, comprising 0.30% Cu and 0.70 gpt Au, starting at surface.
- Includes 24.1 m of 2.50% CuEq or 3.92 gpt AuEq (1.09% Cu and 2.21 gpt Au), starting at 243.9 m.
- With values up to 4% Cu and 5.8 gpt Au over individual assay intervals, these are some of the highest-grade core samples ever returned from a deep drill hole at the Kliyul Main Zone ("KMZ").
- Successfully extended mineralization at the KMZ 75 m to the west; mineralization at KMZ remains open to the west, south and southeast of drill hole KLI-21-037.
"We continue to be extremely pleased with the results from our first ever drill program at Kliyul," said Blaine Monaghan, President and CEO of Pacific Ridge. "Hole KLI-21-037 successfully extended mineralization to the west and the grade compares very favourably to our first hole, which was the best hole ever drilled at Kliyul. We now wait for results from drill hole KLI-21-038, a vertical hole targeted to test the interpreted centre of the porphyry system at KMZ, which was the third and last hole to be drilled during our 2021 drilling campaign."
Discussion of drill hole KLI-21-037
Drill hole KLI-21-037 was a step-out hole to the southwest of drill hole KLI-15-034, drilled by Teck Resources in 2015, which returned 0.18% Cu and 0.53 gpt Au over 245 m (see Table 2), and successfully extended mineralization 75 m to the west. KMZ remains open to the west, south and southeast of drill hole KLI-21-037.
The mineralized interval is hosted in volcaniclastic andesite of the Late Triassic Takla Group, which hosts mineralization at the operating Mount Milligan mine. Alteration is characterized by moderate to strong magnetite-chlorite-quartz +/- epidote-albite alteration and Cu-Au mineralization is hosted in quartz-magnetite-chalcopyrite-pyrite, epidote+/-albite-chalcopyrite-pyrite and anhydrite-magnetite ±chalcopyrite veins, stockworks and disseminations. The last 40 m of the hole encountered an increase in the volume of porphyry-style epidote and anhydrite veins and could indicate proximity to another zone of higher grade mineralization.
Pacific Ridge's first drill hole at Kliyul, KLI-21-036 (see Pacific Ridge news release dated December 1, 2021), intersected 437.0 m of 0.61% CuEq or 0.96 g/t AuEq, the longest and highest-grade interval ever returned from Kliyul.

About the Kliyul Project
Over 60 sq-km in size, Kliyul is located 50 km southeast of Centerra Gold Inc's Kemess mine and 5 km from the Omineca mining road in one of the most geochemically anomalous areas for copper and gold in the prolific Quesnel Terrane. The Project contains five main target areas: KMZ, Bap Ridge, Ginger, M39, and Paprika, each representing an interpreted porphyry centre over a 4 km strike length. KMZ is the most intensely explored of these, with 36 drill holes (7,068 m) drilled since 1974, most of which targeted a near-surface copper-gold magnetite zone (drill holes KL-5 to KL-93-5). Deeper drilling in 2006 and 2015 encountered a porphyry copper-gold system (drill holes KL06-30 to KL-15-35). See Table 2 for selected historical drill results.
The Project displays classic porphyry copper-gold deposit alteration and mineralization patterns. Geological interpretation, supported by a variety of geophysical surveys, including IP, magnetics and magnetotellurics, suggest the potential to significantly expand the size of the Kliyul mineralized system.
Pacific Ridge has the right to earn a 51% interest in the Kliyul and Redton projects from Aurico Metals Inc., a wholly owned subsidiary of Centerra Gold Inc., by making cash payments totaling $100,000, issuing 2.0 million shares and spending $3.5 million on exploration by December 31, 2023. The Company then has the right to increase its interest in the properties to 75% by making additional payments totaling $60,000, issuing 1.5 million shares and completing an additional $3.5 million in exploration by December 31, 2025.
QA/QC
Pacific Ridge's 2021 exploration program was managed by Equity Exploration Consultants Ltd. of Vancouver, B.C. The drill contractor was Atlas Drilling Ltd. of Kamloops, B.C. Drill core was crushed and pulverized and analyzed for 48 elements using a four-acid dissolution followed by ICP-MS (ME-MS61), with a 30 g sample analyzed for gold by fire assay and atomic absorption finish (Au-AA23). Half-core HQ (63.5 mm) or NQ (47.6 mm) sawed samples from continuous intervals throughout drill hole KLI-21-036 were sealed on site and shipped to ALS Minerals preparation lab in Kamloops, BC. Fire assay and multielement analyses were completed at ALS Minerals analytical laboratory in North Vancouver. Blanks, duplicates and commercially certified reference materials were inserted blind into the assay lab sample preparation stream.
