Pacific Ridge (PEX.V): Drilling Underway at Pacific Ridge’s RDP Copper-Gold Project; Kliyul Copper-Gold Drilling Update

Vancouver, British Columbia–(Newsfile Corp. – August 9, 2022) – Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) (“Pacific Ridge” or the “Company”) is pleased to announce that drilling has commenced at its RDP copper-gold project (“RDP” or the “Project”), located in northcentral British Columbia (see Figure 1). The planned 1,500 m diamond drill program is being 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. Pacific Ridge is the operator and is supporting the drill program from the Kliyul copper-gold project (“Kliyul”) camp.

“What an exciting time for Pacific Ridge and its shareholders,” said Blaine Monaghan, President & CEO of Pacific Ridge. “With drilling now underway at RDP, investors have exposure to two active drill programs, RDP and Kliyul, totaling 7,500 m of planned drilling. We believe that both Kliyul and RDP represent an excellent opportunity to make a new copper-gold porphyry discovery.”

About RDP

Located 40 km west of the Company’s flagship Kliyul (see Figure 1), RDP is over 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.

RDP contains several porphyry copper-gold targets 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 (see Figure 2). 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.

Day Target: Mineralization at Day includes pyrite, magnetite, chalcopyrite, minor molybdenite, and local bornite as disseminations, sheeted veins and vein stockworks in diorite and adjacent altered volcaniclastic rocks. Historical drilling includes 2,472 m in 19 drill holes. Drill highlights include 0.67% Cu and 0.93 g/t Au over 58.8 m (drill hole D-74-1) and 0.54% Cu and 0.69 g/t Au over 57 m (drill hole C-92-1). Two drill holes are planned at the Day target.

Roy Target: Mineralization at Roy consists of a quartz-magnetite-chalcopyrite stringer stockwork within a monzonite intrusion. Trench sampling in 1990 encountered 0.121% Cu and 0.55 g/t Au over 62 m within an 80 m trench. Shallow diamond drilling programs have been completed at Roy, but results are incomplete or unavailable except for drill hole EQ-11-01. This hole was drilled in 2011, the last time RDP was explored, and returned 0.11% Cu and 0.64 g/t Au over 122.95 m. One drill hole is planned at the Roy target.

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 g/t Au. Four holes drilled in 1972 returned sporadic results. More recent evaluation of the alteration and soil geochemistry at Porcupine suggests it is epithermal in nature and possibly related to an underlying porphyry system.

Kliyul Copper-Gold Project Drilling Update

The Company is further pleased to announce that the planned 6,000 m diamond drill program is on schedule and on budget. Pacific Ridge has completed 3,939 metres to date and expects to report initial drill results early in the fall.

About Pacific Ridge

Our goal is to become British Columbia’s leading copper-gold exploration company. Pacific Ridge’s flagship project is the Kliyul copper-gold project, located in the prolific Quesnel Trough, approximately 50 km southeast of Centerra Gold Inc.’s Kemess mine. In addition to Kliyul, the Company’s project portfolio includes the RDP copper-gold project (optioned to Antofagasta Minerals S.A.), the Chuchi copper-gold project, the Onjo copper-gold project, and the Redton copper-gold project, all located in British Columbia.
