Pacific Ridge Announces Filing of NI 43-101 Technical Report for Kliyul Copper-Gold Project

Core Viewpoint - Pacific Ridge Exploration Ltd. has filed an independent technical report for the Kliyul copper-gold project, supporting the initial mineral resource estimate for the Kliyul Main Zone, which is part of a larger porphyry copper-gold trend in British Columbia [1][2]. Summary by Sections Mineral Resource Estimate - The Kliyul Main Zone (KMZ) hosts 334.1 million tonnes grading 0.33% copper equivalent (CuEq), 0.15% copper, 0.26 g/t gold, and 0.95 g/t silver in the Inferred Mineral Resource category [2][3]. - KMZ contains 2.42 billion pounds of CuEq, which includes 1.11 billion pounds of copper, 2.74 million ounces of gold, and 10.22 million ounces of silver in the Inferred Mineral Resource category [2]. Geological Context - KMZ is one of several target areas within a six-kilometre long porphyry copper-gold trend characterized by favorable geology, geochemistry, alteration, and geophysics [3]. - Mineralization at KMZ remains open for expansion both within and beyond the resource reporting shell used to restrict the resource model [3]. Drilling Activities - The company completed two drill holes totaling 1,287 metres at KMZ in 2025, focusing on infill and resource expansion, with assays pending [4][21]. - Since 2020, the company has invested over $15 million and drilled more than 20,000 metres at Kliyul [13]. Historical Drilling Results - The best drilling result in 2021 was 316.7 metres of 0.79% CuEq within 566.7 metres of 0.51% CuEq [13]. - The best drilling result in 2022 was 328.0 metres of 0.64% CuEq within 526 metres of 0.49% CuEq [21]. - The best drilling result in 2023 was 305.5 metres of 0.59% CuEq within 540.3 metres of 0.44% CuEq [21]. Project Infrastructure - Kliyul is over 90 km² in size and is located in the prolific Quesnel terrane, close to existing infrastructure, approximately 8 km from the Omineca Resource Road and a 230 kV high-voltage power line [13]. Company Overview - Pacific Ridge aims to become British Columbia's leading copper exploration company, with Kliyul as its flagship project, alongside other projects including RDP, Chuchi, Onjo, and Redton [24].
