Pacific Ridge Identifies Six-Kilometre-Long Copper-Gold Porphyry Trend at Chuchi Copper-Gold Project

In This Article:

Vancouver, British Columbia--(Newsfile Corp. - April 30, 2024) - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) (FSE: PQWN) ("Pacific Ridge" or the "Company") is pleased to announce that it has identified a six kilometre ("km") long copper-gold porphyry trend at the Chuchi copper-gold project ("Chuchi" or the "Project") located in the prolific Quesnel Terrane in northcentral British Columbia 35 km northeast of Centerra Gold Inc.'s ("Centerra") Mount Milligan Mine (see Figure 1).

Since acquiring Chuchi in May 2022, Pacific Ridge has completed airborne and ground-based geophysics programs and a gridded soil sampling and mapping program at the Project. This, combined with compilation and review of historical data, has resulted in the development of an exploration model for a six km long copper-gold porphyry trend (see Figure 2) that includes several highly prospective target areas, including the BP Zone, which hosts a historical geological resource of 50 million tonnes with grades between 0.21 - 0.40% copper and 0.21 - 0.44 grams per tonne ("g/t") gold1. This historical geological resource is not compliant with National Instrument 43-101 standards. A Qualified Person has not done sufficient work to classify the historical geological resource as current mineral resources or mineral reserves and Pacific Ridge is not treating the historical geological resource as current mineral resources or mineral reserves. Investors are cautioned that the historical geological resource does not mean or imply that economic deposits exist at Chuchi.

Highlights:

  • The BP Zone is a 550 metres x 450 metres x 650 metres ("m") interpreted porphyry intrusive complex 3D ZTEM anomaly with two IP anomalies spanning more than 1 km. Although historic drilling at the BP Zone returned significant porphyry copper-gold mineralization, including drill hole CH-90-27 which returned 194.0 m at 0.21% copper and 0.21 g/t gold (see Table 1 for more BP Zone results). The BP Zone has not been adequately drill tested.

  • The Digger Zone is an open 500 x 250 x 200 m IP anomaly where drill hole CH-91-42 intersected 229.2 m at 0.10% copper and 0.61 g/t gold and ended in mineralization.

  • The BP Zone and the Digger Zone have significant, untested potential for porphyry copper-gold mineralization at depth as many of the historic drill holes were shallow, less than 150 m in depth, and ended in mineralization.

  • The Coho Zone includes a 400 m x 250 m x 200 m interpreted porphyry intrusive complex 3D ZTEM anomaly with a two-limbed IP chargeability high anomaly that spans more than 1.4 km and has a similar geometry as mineralization trends at the nearby Mount Milligan Mine. This target has never been drilled.
