Pacific Ridge Exploration Ltd. announced results from this year's diamond drill campaign at the RDP copper-gold project, located in northcentral British Columbia, 40 km west of the Company's Kliyul copper-gold project. Antofagasta Minerals S.A. can earn a 75% interest in RDP by spending $10,000,000 on exploration over eight years and delivering a preliminary economic assessment report. Pacific Ridge is the operator and supported the diamond drill program from Kliyul camp.

The 2023 diamond drilling program at RDP totaled 1,428 metres in three drill holes (RDP-23-007 to RDP-23-009) and tested the Day target ("Day") and the Bird target ("Bird"). Two drill holes were completed at Day (RDP-23-005 and RDP-23-008) where drill hole RDP-22-005 returned 107.2 m of 1.39% copper equivalent ("CuEq") or 2.06 g/t gold equivalent ("AuEq") (0.63% copper, 1.10 g/t gold, and 2.91 g/t silver) within 497.2 m of 0.66% CuEq or 0.97 g/t AuEq (0.37% copper, 0.40 g/t gold, and 1.60 g/t silver). The two holes completed at Day were large step-outs over 300 m to the northeast and northwest from the collar location for RDP-22-005.

It remains open to the east and west, and at depth. Drill hole RDP-23-009 was the first diamond drill hole to test Bird at depth and returned 18.5 m of 0.43% CuEq or 0.63 g/t AuEq® (0.16% copper, 0.38 g/t gold, and 0.59 g/t silver) within 111.0 m at 0.23% CuEq* or 0.34 g/t AuEq.0.09% copper, 0.20 g/t gold, and0.31 g/t silver). Geochemistry and geophysics suggest that a porphyry core may lie approximately 200 m deeper than the mineralization intersected in RDP-23-009.

However, there are four notable intervals starting from 18.6 m that increase in Au:Cu ratio with depth suggesting RDP-23-009 is moving towards a porphyry centre with increasing depth.
