Drilling Underway at Pacific Ridge's Kliyul Copper Gold Porphyry Project

Vancouver, August 5, 2021 - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) ("Pacific Ridge" or the "Company") is pleased to announce that the diamond drill program is now underway at the Kliyul copper-gold porphyry project ("Kliyul" or "Project"), located in the prolific Quesnel Trough in Northwest British Columbia (see Figure 1). The Company plans to drill a minimum of 2,500 metres testing the Kliyul Main Zone ("KMZ") and two newly defined adjacent targets, Kliyul East and Kliyul West.

Limited historical drilling at Kliyul returned significant copper-gold porphyry mineralization, drill hole KLI-15-34 intercepted 245 metres of 0.75% CuEQ¹ (see Pacific Ridge news release dated December 2, 2020). Based on historical drilling (see Table 1), alteration and lithogeochemical indicators from surface exposures, as well as magnetics and IP surveys, Pacific Ridge believes that there is excellent potential to significantly expand the mineralized footprint at Kliyul, laterally and to depth.

"Kliyul represents an excellent opportunity to make a new copper-gold porphyry discovery," said Blaine Monaghan, President and CEO of Pacific Ridge. "Our exploration team and Technical Advisory Committee have done an outstanding job compiling and interpreting all of the data and selecting drill targets. I look forward to reporting the drill results to shareholders."

In addition to drilling, the 2021 exploration program at Kliyul will include geological mapping and sampling, a high resolution airborne magnetic survey and additional IP surveying over the Bap Ridge and M39 Zone targets, south of the Main Zone (see Figure 2).

About the Kliyul Project

Over 60 square kilometres 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 Quesnel Terrane. The Project contains four main target areas: KMZ, Bap Ridge, Ginger and M39, each representing an interpreted porphyry centre over a 4 km strike length. KMZ is the most intensely explored of these, with 33 drill holes (5,524 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 KL-06-30 to KL-15-35). See Table 1 (Selected historical drill results) and Figure 3 (Plan view of 2021 drill targets) for further information.

The Project displays classic 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.

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.

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 Kliyul copper-gold project, located in the Quesnel Trough, approximately 50 km southeast of Centerra Gold's Kemess mine. In addition to Kliyul, the Company's project portfolio includes the RDP copper-gold project and the Redton copper-gold project, both located in British Columbia. Pacific Ridge will continue to search for projects that offer discovery opportunity in our regions of expertise.

¹Copper equivalent (CuEQ) is equal to ((Cu (per cent) multiplied by $2.25 multiplied by 22.0642) plus (Au (g/t) multiplied by $1,650 multiplied by 0.032151)) divided by ($2.25 multiplied by 22.0642).
