Pacific Ridge Exploration Ltd. Commences Drilling at RDP Copper-Gold Project

Pacific Ridge Exploration Ltd., a leading copper exploration company, has announced the commencement of drilling at its 100% owned RDP copper-gold project located in British Columbia's Golden Horseshoe. The project is situated at the southern end of the Toodoggone Mining District, approximately 40 kilometers west of the company's flagship Kliyul copper-gold project.

The Toodoggone Mining District has emerged as one of Canada's most promising exploration districts, with numerous senior mining companies making strategic investments or entering joint ventures in recent years. Pacific Ridge's decision to return to the RDP project reflects the company's confidence in the district's potential for significant discoveries. As stated by Blaine Monaghan, President & CEO of Pacific Ridge, the Toodoggone Mining District has quickly become Canada's hottest exploration district, with the company excited to test the interpreted porphyry center at Day and further define last year's western magnetic lobe discovery.

The current drill program at the Day target, one of the target areas at RDP, aims to drill approximately 3,000 meters. The target was selected based on the results of the 2025 drill program, which returned 112.2 meters of 1.35% copper equivalent or 2.02 g/t gold equivalent within 405.0 meters of 0.71% copper equivalent or 1.06 g/t gold equivalent in drill hole RDP-25-011. The company's goal is to test the interpreted porphyry center between the western and eastern lobes and more fully define the 2025 western lobe discovery.

Prior to the commencement of drilling, Pacific Ridge completed extensive airborne geophysical surveys, including 1,057 line-kilometers of high-resolution, 60-meter-spaced magnetics and 283 line-kilometers of 200-meter-spaced magnetotellurics. These surveys are expected to enhance drill targeting by providing valuable information on mineralization and alteration zones, key structural controls, intrusive complexes, and potential deep hydrothermal conduits. Additionally, 9 line-kilometers of 100-meter-spaced ground Induced Polarization geophysics were completed over the Day target to further refine sulphide targets, map quartz veining and alteration, and evaluate the depth potential of the porphyry system.

Pacific Ridge's project portfolio includes the Kliyul copper-gold project, the Onjo copper-gold project, and the Redton copper-gold project, all located in British Columbia. The company acknowledges that its projects are situated in the traditional, ancestral, and unceded territories of several First Nations, including the Gitxsan Nation, McLeod Lake Indian Band, Nak'azdli Whut'en, Takla Nation, and Tsay Keh Dene Nation. As a responsible mining company, Pacific Ridge is committed to respecting the rights and interests of indigenous communities and working collaboratively to ensure the long-term sustainability of its operations.

The commencement of drilling at the RDP copper-gold project marks an exciting milestone for Pacific Ridge Exploration Ltd. As the company continues to advance its exploration activities, investors and industry watchers will be closely monitoring the progress and potential discoveries at this promising project. With its strong project portfolio and commitment to responsible mining practices, Pacific Ridge is well-positioned to become a leading player in the copper exploration sector.
