Field Crews Mobilized to Pacific Ridge's Kliyul and RDP Copper-Gold Porphyry Projects

Vancouver, British Columbia--(Newsfile Corp. - June 29, 2022) - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) ("Pacific Ridge" or the "Company") is pleased to announce that field crews have been mobilized to the Kliyul copper-gold project ("Kliyul") and that camp construction is underway. The exploration camp at Kliyul will also support exploration activities at the RDP copper-gold project ("RDP"), which is located 40 km to the west (see Figure 1).

Pacific Ridge anticipates that the planned 6,000 m diamond drill program at Kliyul will commence sometime next week and that the planned 1,500 m diamond drill program at RDP, under option to Antofagasta Minerals S.A. ("Antofagasta"), a wholly owned subsidiary Antofagasta PLC (ANTO: LSE), will start at the beginning of August. Priority drill holes at Kliyul include a step-out to the west of hole KLI-21-037 (316.7 m of 0.75% CuEq or 1.17 g/t AuEq) as well as step-outs to the south and east of KLI-21-036 (437 m of 0.61% CuEq or 0.96 g/t AuEq) and hole KLI-21-38 (342 m of 0.50% CuEq or 0.78 g/t AuEq).

"Pacific Ridge's busiest exploration season in decades is about to begin," said Blaine Monaghan, President and CEO of Pacific Ridge. With a planned 6,000 m drill program at Kliyul, the largest ever drill program at Kliyul, and a partner funded drill program at RDP, shareholders can look forward to a steady stream of news."

Kliyul

The exploration program at Kliyul will utilize two drill rigs under contract from Dorado Drilling Ltd. This will be the largest ever diamond drill program at Kliyul and will focus on expanding mineralization at the Kliyul Main Zone ("KMZ") laterally and to depth. Drilling in 2021 at KMZ returned the longest and highest-grade intersections ever encountered at Kliyul (see Table 1) and mineralization remains open in all directions. Pacific Ridge has modelled the known mineralization using major element geochemistry, trace element geochemistry and alteration mineralogy. These models combined with geophysical signatures, primarily from IP and magnetics, have defined priority step-out targets to the west, to the south, to the east, and at depth (see Figures 2 and 3). In addition to diamond drilling, the Company is planning an IP survey over the Bap Ridge and M-39 targets, and an airborne magnetic survey over a 4-km long mineralized trend that hosts additional porphyry targets (see Figure 4). The surveys will be used to refine targets for possible drill testing during the 2022 program and to define future drill targets.

Table 1

2021 Kliyul Assay Results Summary

* End of hole
**CuEq = ((Cu%) x $Cu x 22.0462) + (Au(g/t) x $Au x 0.032151)) / ($Cu x 22.0462)
***AuEq = ((Cu%) x $Cu x 22.0462) + (Au(g/t) x $Au x 0.032151)) / ($Au x 0.032151)

Commodity prices: $Cu = US$4.00/lb and $Au = US$1,750/oz.

Factors: 22.0462 = Cu% to lbs per tonne, and 0.032151 = Au g/t to troy oz per tonne.

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

Pacific Ridge can acquire up to a 75% interest in Kliyul and Redton from Aurico Metals Inc. ("Aurico"), a wholly owned subsidiary of Centerra Gold Inc. ("Centerra") (TSX: CG) (NYSE: CGAU), 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 make the required exploration expenditures to earn the 75% interest in Kliyul and Redton after this year's exploration program.

RDP

The Company recently optioned RDP to Antofagasta, whereby Antofagasta can earn a 75% interest in RDP by spending $10,000,000 on exploration over eight years and delivering a preliminary economic assessment report (see news release dated February 8, 2022). Mineralization at the Day target (see Figure 5) 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. 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 from 13.1 m depth (drill hole D-92-1). Mineralization at the Roy target consists of a quartz-magnetite-chalcopyrite stringer stockwork within a monzonite intrusive. Trench sampling in 1990 encountered 0.121% Cu and 0.55 g/t Au over 62 m within an 80 m trench. Only a single drill hole has been documented at Roy, 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 from 3.05 m depth.

Antofagasta is funding a 1,500 m diamond drill program at RDP with a focus on the Day and Roy targets. Drilling is expected to commence in August.
