Pacific Ridge Exploration Ltd. announce that the Company completed 10,284 m of diamond drilling at its 100% owned Kliyul copper-gold project and 1,428 m at the RDP copper-gold project. Kliyul is located in the prolific Quesnel Terrane, close to existing infrastructure, and RDP is located 40 km to the west of Kliyul in the Stikine Terrane. 10,284 m of diamond drilling was completed in 19 drill holes at Kliyul, making the 2023 exploration program the largest ever on the Project.

8,965 m in 16 drill holes in six contiguous fault block zones of the Kliyul porphyry copper-gold complex tested an area measuring approximately 1,300 m east-west, 600 m north-south, and up to 650 m vertical depth. 1,319 m in three drill holes tested three interpreted porphyry centres (Ginger, Ginger South, and Parish Hill) up to 1.5 km from the Kliyul Main Zone. Pacific Ridge has reported assay results from the first four diamond drill holes with hole KLI-23- 054 returning 305.5 m of 0.23% copper, 0.51 g/t gold, and 1.22 g/t silver within 540.3 m of 0.19% copper, 0.36 g/t gold, and 1.09 g/t silver.

The results from the remaining 15 drill holes completed at Kliyul will be released once assays are received and compiled. 1,428 m of diamond drilling was completed in three drill holes at RDP. 987 m in two broad step-out holes (over 300 m each) from drill hole RDP-22-005, which returned 107.2 m of 0.63% copper, 1.10 g/t gold, and 2.91 g/t silver within 497.2 m of 0.37% copper, 0.40 g/t gold, and 1.6 g/t silver at the Day Target in 2022.

441 m in one drill hole completed at the Bird target where the Company discovered porphyry copper-gold mineralization in an outcrop exposed in a stream cutbank in 2022. The results from the three drill holes completed at RDP will be released once assays are received and compiled. The 2023 Kliyul drilling program was completed on September 14th with the termination of drill hole KLI- 23-069 at 655 m (55 m beyond planned depth).

Seasonal progressive reclamation and exploration camp demobilization is underway. The total of 10,284 m of diamond drilling at Kliyul followed the decision to reallocate 2,000 m of drilling originally planned for the Company's Chuchi copper-gold project increasing the planned 2023 drilling at Kliyul from 7,000 m to 9,000 m. An additional 1,284 m of drilling was due to operational efficiencies. The 10,284 m diamond drilling program is the largest ever seasonal drilling program to be completed at Kliyul.

The objectives of the 2023 Kliyul exploration drilling program were to expand the known extents of the Kliyul porphyry copper-gold complex and to test several high-priority interpreted porphyry centres occurring along the Divide Lake Fault and Valley Fault corridors. The 2023 RDP drilling program was completed on September 2nd with termination of drill hole RDP-23- 009 at 441 m. Drill rig demobilization and seasonal progressive reclamation have been completed. A total of 1,428 m of diamond drilling was completed in three drill holes and tested two porphyry copper- gold prospects, Day and Bird.

The 2023 drill program at RDP was funded by Antofagasta Minerals S.A., a wholly owned subsidiary of Antofagasta PLC. 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. Pacific Ridge is the operator and supported the RDP exploration program from Kliyul camp, located 40 km to the east.
