Pacific Ridge Intersects 289 m of 0.77% Copper Equivalent or 1.15 g/t Gold Equivalent at Kliyul Copper-Gold Project; Expands Mineralization 110 m to the West

Core Insights - Pacific Ridge Exploration Ltd. announced significant drilling results from its Kliyul copper-gold project, with drill hole KLI-25-070 intersecting 289.0 m of 0.77% copper-equivalent (CuEq) or 1.15 g/t gold-equivalent (AuEq) [1][3][4] - The 2025 drill program successfully expanded mineralization at the Kliyul Main Zone (KMZ) and confirmed the presence of a high-grade copper-gold mineralized zone [3][4][24] Drilling Highlights - Drill hole KLI-25-070 returned one of the best intervals recorded at KMZ, while KLI-25-071 extended mineralization 110 m to the west [3][4] - The 2025 program included two drill holes totaling 1,287 m, focused on infill and resource expansion at KMZ, which hosts an Inferred Mineral Resource of 334.1 million tonnes grading 0.33% CuEq [4][24] Detailed Assay Results - KLI-25-070 showed 289.0 m of 0.77% CuEq, including 110.0 m of 0.26% copper and 0.75 g/t gold, while KLI-25-071 returned 91.0 m of 0.47% CuEq [4][9] - The results indicate a high gold to copper ratio (>2) in KLI-25-070, similar to previous successful drill holes [4][9] Future Exploration Plans - The company plans to continue resource expansion drilling at KMZ and explore additional targets along a 6-km mineralized trend, including the newly identified Klip target [24][27] - The Klip target is based on historical data indicating potential for significant mineralization, with previous samples yielding 3.8 g/t gold and 5.3 g/t silver [24][27]
