PACIFIC RIDGE PROVIDES DRILLING UPDATE FOR KLIYUL AND RDP COPPER-GOLD PROJECTS

Pacific Ridge Exploration Ltd. has provided a drilling update for the company's 100-per-cent-owned Kliyul copper-gold project and RDP copper-gold project, both located in B.C.'s Golden Horseshoe at the southern end of the Toodoggone district.

Drilling highlights:

• Two drill holes, totalling 1,287 metres, were completed at Kliyul and were focused on infill and resource expansion at the Kliyul Main zone (KMZ), which hosts 334.1 million tonnes grading 0.33 per cent copper equivalent (0.15 per cent copper, 0.26 gram per tonne gold and 0.95 gram per tonne silver) in the inferred mineral resource category (see news release dated Aug. 6, 2025).
• Five drill holes, totalling 2,156 metres, were completed at RDP and were focused on the Day target, which returned one of British Columbia's best porphyry copper-gold intervals in 2022: Drill hole RDP-22-005 intersected 107.2 m of 1.39 per cent CuEq, or 2.06 g/t gold equivalent (0.63 per cent copper, 1.10 g/t gold and 2.91 g/t silver) (see news release dated Oct. 25, 2022).
• Drilling at both Kliyul and RDP intersected strong copper mineralization.

2025 Kliyul drill program

The 2025 drill program at Kliyul was focused on infill and resource expansion at KMZ.

KLI-25-070, the first drill hole of the program, was collared south of the Valley fault and was designed to test an approximately 130-metre gap in drilling north of strong copper-gold mineralization in holes KLI-21-036 and KLI-21-038. KLI-25-070 was collared from the same location as KLI-21-036 and drilled at an azimuth of 354 degrees and dip of 80 degrees from an elevation of 1,765 m to a depth of 786 m. The hole intersected chalcopyrite and bornite mineralization with quartz-magnetite veins and stockworks and as disseminations as well as chalcopyrite-plus-or-minus-bornite and pyrite mineralization associated with epidote and anhydrite veins.

KLI-25-071 was collared west of KLI-23-068 to test for copper-gold mineralization extensions to the west within the mineral resource estimate pit shell. KLI-25-071 was drilled at an azimuth of 180 degrees and dip of 75 degrees from an elevation of 1,776 m to a depth of 501 m. Chalcopyrite-pyrite mineralization occurs as disseminations with epidote-magnetite alteration, with quartz-sericite-chlorite veins, quartz-anhydrite veins and, locally, quartz-magnetite veins.

2025 RDP drill program

The 2025 drill program at RDP was focused on the Day target with the objective of confirming that the porphyry copper-gold-silver mineralization intersected in RDP-22-005 is hosted in a westward-striking, steeply northward-dipping tabular body and also to test the western magnetic lobe.

RDP-25-010, the first drill hole of the 2025 exploration program, was located 40 m southwest of RDP-22-005. RDP-25-010 was drilled at an azimuth of 60 degrees and dip of 72 degrees. A stockwork of quartz-magnetite-sulphide veins was encountered in the first five m of drilling; however, a late mineral intrusive was intersected from five m to 175.5 m and the hole was terminated.

RDP-25-011 was drilled from the same location at an azimuth of 48 degrees and dip of 65 degrees to a depth of 431 m and cut underneath and to the northwest of RDP-22-005. Patchy potassic alteration (K-feldspar-magnetite) was intersected as well as intervals of strong quartz-magnetite sulphide veining and chalcopyrite-plus-or-minus-bornite mineralization hosted in early-mineral monzodiorite and hydrothermal breccia, extending mineralization to the north of RDP-22-005 by a minimum of 50 m, with mineralization still being open to the north.

RDP-25-012 (48 degrees/minus 65 degrees/363 m length) and RDP-25-013 (160 degrees/minus 70 degrees/582 m length) were drilled from a site 170 m northeast of RDP-22-005 to test the interpreted tabular porphyry copper-gold mineralization geometry between RDP-22-005 and RDP-23-007, which was collared 300 m northeast of RDP-22-005 and ended in 19.0 m of 0.45 per cent CuEq or 0.67 g/t AuEq (0.32 per cent copper, 0.19 g/t gold and 1.08 g/t silver) (see news release dated Nov. 23, 2023). Chalcopyrite and bornite mineralization hosted in early-mineral, potassically altered monzodiorite intrusive rocks and hydrothermal breccia were intersected, which confirmed the concept of a tabular geometry. Copper-sulphide mineralization was intersected to a vertical depth of 500 m in RDP-25-013 and it remains open.

RDP-25-014, the final drill hole of the 2025 RDP drill program, was designed to test the western magnetic lobe for copper-gold mineralization. RDP-25-14 was drilled at an azimuth of 335 degrees and dip of 65 degrees to a depth of 604 m. Chalcopyrite-pyrite and chalcopyrite-bornite mineralization occur as disseminations, with quartz-carbonate and epidote-actinolite veins crosscutting potassium-feldspar and magnetite-altered monzodioritic intrusions.
