Vancouver, B.C. – June 17, 2021 - Pacific Ridge Exploration Ltd. (PEX: TSX Venture; PEXZF: OTCBB) ("Pacific Ridge" or the "Company”) plans to launch a fully funded 2,500 metre diamond drill program at the Kliyul copper-gold project (“Kliyul” or the “Project”) this July. The Company also plans to conduct exploration at the RDP copper-gold project and the Redton copper-gold project. All three projects are located in the prolific Quesnel Trough in northwestern British Columbia (see Figure 1).
“Pacific Ridge’s 2021 exploration season promises to be an exciting one for several reasons” said Blaine Monaghan, President and CEO of Pacific Ridge. “It will be the largest exploration program undertaken in nearly a decade and it will be our first drill program at Kliyul, which represents an excellent opportunity to make a new copper-gold porphyry discovery. Although Kliyul has seen limited drilling, significant copper-gold porphyry mineralization was intersected in several historic drill holes. We plan to follow up these holes with the goal of extending the mineralization laterally and to depth.”

A high priority drill target at Kliyul is the Kliyul Main Zone (“KMZ”) where historic drilling encountered significant copper-gold porphyry mineralization, including drill hole KLI-15-34 which returned 245 metres of 0.75% CuEQ1. Pacific Ridge believes that there is excellent potential to find additional copper-gold mineralization along strike and at depth at KMZ . The Company also plans to drill two newly defined adjacent targets, Kliyul East and Kliyul West. Together, KMZ, Kliyul East and Kliyul West cover a strike length of 1.5 kilometres. (see Figure 2). Drill targeting at KMZ, Kliyul East and Kliyul West was guided by alteration and lithogeochemical indicators from surface exposures and historical drilling, as well as magnetics and Induced Polarization (IP) geophysical surveys.

In addition to the drill program, Pacific Ridge is planning a geological mapping and sampling program at Kliyul, and a high-resolution airborne magnetic survey and IP survey over the Bap Ridge and M39 Zone targets (see Figure 3).

Kliyul is over 60 square kilometres in size and is only 5 kilometres from road and power in one of the most geochemically anomalous areas for copper and gold in the Quesnel Terrane. The Project contains several Minfile occurrences, including four main target areas: KMZ, Bap Ridge, Ginger-Shadow and M39, each representing a potential porphyry centre over a 4-kilometre strike length.
The KMZ is the most intensely explored of these potential porphyry centres with 33 drill holes (5,524 m) drilled since 1974, most of which targeted a near-surface copper-gold magnetite skarn zone. Deeper drilling in 2006 and 2015 encountered a porphyry copper-gold system. Drill highlights are shown in the table below.
KMZ Drill Results Table
Kliyul displays classic alkalic copper-gold porphyry 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, including the main porphyry mineralizer.
Over 38 square kilometres in size, RDP is located 40 kilometres to the west of Kliyul 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. RDP is also in a similar geological environment to NorthWest Copper’s new East Niv discovery, located 20 kilometres to the north.

RDP contains several copper-gold porphyry targets that have been explored intermittently since the early 1970’s. Work included prospecting and mapping, various geochemical surveys, ground and airborne geophysical surveys, trenching and a limited amount of drilling. The property is underlain by Hazelton Group volcanic and sedimentary rocks of the Stikine Terrane intruded by the lower Jurassic Roy plutonic suite including plugs, sills, and stocks of porphyritic dacite to monzodiorite composition, the Fir gabbro, and the Gyr rhyolite porphyry.
Roy Target: The Roy showing was discovered in 1973. Mineralization at the Roy showing consists of a quartz-magnetite-chalcopyrite stringer stockwork within a monzonite intrusive. Trenching in 1991 encountered 0.121% Cu and 0.55 gpt Au over 62 m within an 80 m trench2. Only a single hole has been documented at Roy, in 2011, and encountered 0.11% Cu and 0.64 gpt Au over 122.95 m in hole EQ-0013.
Day Target: The Day showing was discovered at about the same time as the nearby Sustut Copper Deposit. Mineralization includes pyrite, magnetite, chalcopyrite, minor molybdenite, and traces of bornite as disseminations and fracture fillings in diorite and adjacent altered volcaniclastic rocks. Historical drilling includes 2,472 m in 19 drill holes. Highlights include 0.67% Cu and 0.93 gpt Au over 58.8 m in hole D-74-14 and 0.54% Cu and 0.75 gpt Au over 57 m in hole C-92-14.
Porcupine Target: Discovered in 1972, the Porcupine Target, was explored as a stratabound massive sulphide target. Float samples assayed as high as 17.2% Cu and 0.19% Cu with 7.98 gpt Au5. Four holes drilled in 1972 encountered sporadic results. More recent evaluation of the alteration and soil geochemistry at Porcupine suggests the potential for porphyry style mineralization.
RDP 2021 Exploration Plans
Pacific Ridge is planning a property-wide mapping and sampling program to fully define the nature and extent of porphyry alteration and mineralization centres. Data from a detailed aeromagnetic survey flown over the property in 2011 will be re-processed and reinterpreted as an aid to defining porphyry centres. Remote sensing processing will also be carried out to identify favourable alteration and assist in defining targets. In order to take advantage of the infrastructure and logistics that will be in place for the Kliyul drill program, the exploration program at RDP will run concurrent to the Kliyul drill program.
Redton is a porphyry copper-gold project that adjoins NorthWest Copper’s Kwanika project (Measured and Indicated Resource of 223.6 million tonnes grading 0.27% copper, 0.25 gpt gold and 0.87 gpt silver containing 1.32 billion pounds of Cu, 1.83 million ounces of Au and 6.27 million ounces of Ag6). Redton is road accessible and contains a number of untested drill targets (see Figure 5).
Redton 2021 Exploration Plans
Data from an AeroTEM magnetic and airborne survey is being modeled and reinterpreted with a view to outlining potential porphyry centres, in the area of the Catchment Basin and East Redton targets, where soils are locally enriched in copper and molybdenum. A field program is planned in late summer to ground truth these targets.

About Pacific Ridge
Our goal is to become one of the leading copper-gold exploration companies in British Columbia. Pacific Ridge’s flagship project is the advanced-stage Kliyul copper-gold project, located in the Quesnel Trough, approximately 50 km southeast of Centerra Gold’s Kemess project. Historic drilling at Kliyul encountered significant copper-gold porphyry mineralization, drill hole KLI-15-34 returned 245 metres of 0.75% CuEQ1 (see Pacific Ridge press release dated December 2, 2020). The Company plans to launch a drill program at Kliyul this summer.
