Pacific Ridge Exploration Ltd. announce that an induced polarization ("IP") survey is underway at the Company's Chuchi copper-gold project ("Chuchi") and the Onjo copper-gold project ("Onjo"). Both projects are located in the prolific Quesnel Terrane in northcentral B.C. In late July, the Company announced that it had to cancel the planned exploration program at Chuchi due to wildfires and an Area Restriction order in the Nation Lakes area. However, the order has now been lifted and Pacific Ridge has resumed the planned IP survey at Chuchi, which was expanded to include the Company's 100% owned Onjo project.

A total of 37.5 line-kms is planned in eight IP lines at Chuchi and Onjo. This includes three IP lines (12.5 line-km) at Chuchi to further extend historical IP survey coverage over the BP and Klaw zones; three IP lines (15 line-km) at Chuchi South over Coho and Coho West; and two IP lines at Onjo over Chica and Gingla, which were defined during the 2022 Onjo exploration program. Accessible via a network of forestry roads, Onjo is over 14,600 hectares in size and adjoins the western boundary of Centerra Gold Inc.'s Mount Milligan Mine, an alkalic porphyry copper-gold system.

Onjo hosts skarn and alkalic porphyry copper-gold mineralization associated with monzonitic phases of the Witch Lake intrusions cutting Takla volcanic rocks, similar to the mineralization and host rocks at the Mount Milligan Mine. The style of copper-gold mineralization returned in historical drilling, combined with the presence of nearby skarn occurrences, leads Pacific Ridge to believe that past operators encountered the upper or peripheral levels of a tilted alkalic porphyry system and that Onjo has the potential to host an alkalic porphyry copper-gold deposit at depth.
