Pacific Ridge Exploration Ltd. announced additional drill results, for holes KLI-23-055 to KLI-23-058, from this year's diamond drilling campaign at the Kliyul copper-gold porphyry project ("Kliyul" or "Project") with drill hole KLI-23-058 intersecting 103.5 m of 0.63% copper equivalent ("CuEq") (0.18% copper, 0.66 g/t gold, and 0.93 g/t silver) within 388.5 m of 0.42% CuEq (0.18% copper, 0.35 g/t gold and 1.05 g/t silver). Kliyul is located in the prolific Quesnel Terrane in northcentral British Columbia close to existing infrastructure. Pacific Ridge completed a total of 19 diamond drill holes (KLI-23-051 to KLI-23-069) totaling 10,284 metres at Kliyul this year, the largest ever exploration program at Kliyul.

The Company announced drill results for holes KLI-23-051 to KLI-23-054 in August with drill hole KLI-23-054 intersecting 305.5 m of 0.59% CuEq (0.23% copper, 0.51 g/t gold, and 1.22 g/t silver). Results from the remaining 11 drill holes will be released once they are received and compiled. Highlights: KLI-23-058 returned 103.5 m of 0.63% CuEq (0.18% copper, 0.66 g/t gold, and 0.93 g/t silver) within 388.5 m of 0.42% CuEq (0.18% copper, 0.35 g/t gold and 1.05 g/t silver) from the Kliyul North zone.

This interval represents a 130 m northern step-out from copper-gold mineralization in KLI-21-036 which returned 291.7 m of 0.79% CuEq (0.28% copper, 0.74 g/t gold and 2.04 g/t silver within 437 m of 0.64% CuEq (0.22% copper, 0.60 g/t gold and 1.62 g/t Ag). KLI-23-058 returned the best result from the Kliyul North zone to date and further proves that Kliyul Main Zone ("KMZ") mineralization extends into adjacent fault blocks. KLI-23- 058 is one of three steep drill holes (also KLI-23-060 and KLI-23-069) spaced 100 m apart that were drilled as an east-west fence across the Kliyul North zone.

Results of the other two drill holes are pending. Known extents of the Kliyul porphyry copper-gold complex now measure 600 m east-west, up to 600 m north-south (previously 450 m north-south), and up to 600 m vertical depth. KLI-23-057, drilled on the eastern side of the KMZ, returned 89.3 m of 0.38% CuEq (0.21% copper, 0.25 g/t gold and 0.91 g/t silver) from 290 m and 80.0 m of 0.37% CuEq (0.10% copper, 0.39 g/t gold and 0.85 g/t silver) from 433 m, extending KMZ mineralization 200 m east of KLI-22- 045 and 135 m west of KLI-22-049, increasing confidence in the continuity of mineralization over a 600 m east-west distance from the western extent of KMZ to KLI-22-049 in East Wedge.

KLI-23-056, drilled in Kliyul North as a 100 m step out to the west and north of KLI-22-046, returned 37.2 m of 0.27% CuEq (0.14% copper, 0.19 g/t gold and 1.07 g/t silver) from 513 m. While this is a narrow, low-grade interval, it is the second mineralized interval to intersect the western margin of a 400 x 200 m magnetic vector inversion anomaly ("MVI") and Tilt Derivative ("TDR") in an underexplored part of the Kliyul porphyry copper-gold complex, called Kliyul NE. From this same anomaly, KLI-22-046 returned 59.0 m of 0.84% CuEq (0.24% copper, 0.87 g/t gold, and 2.29 g/t silver) within 169 m of 0.52% CuEq (0.20% copper, 0.46 g/t gold, and 1.65 g/t silver). The main body of the anomaly remains open and undrilled 400 m northeast of the center of KMZ.

KLI-23-055, was the first drill hole to test the Ginger target, an interpreted standalone porphyry target area 1.3 km northwest of the center of KMZ and at an elevation 200 m above KMZ. Drilling intersected a broad zone of chlorite-sericite and sericitic alteration with late- stage veins. Massive white quartz veins, interpreted as D-veins or late Lode veins, have low-grade gold returning 19.1 m of 0.36 g/t gold equivalent ("AuEq") (0.01% copper, 0.34 g/t gold and 0.65 g/t silver).

The veins are also anomalous in copper, molybdenum (up to 0.12% over 1.25 m), tungsten, tellurium, and bismuth. A combination of IP chargeability high (>20 mV/V), DC resistivity high (>2000 ohm-m) and moderate-to-high MVI Induced 3D model values continues to be a reliable geophysical targeting signature for mineralization at Kliyul. In addition, a TDR standard filtering of the 2022 aeromagnetic data is now being used to enhance and refine the Kliyul porphyry copper-gold complex footprint.
