Pacific Ridge begins drill program at Kliyul

Executive Summary

• Pacific Ridge Exploration has commenced a 2,500‑metre infill drilling program at the Kliyul copper‑gold project’s Main zone (KMZ) to expand its inferred resource.
• KMZ currently hosts an inferred 334.1 Mt grading 0.33 % CuEq (2.42 M lb CuEq), including 1.11 M lb Cu, 2.74 Moz Au and 10.22 Moz Ag.
• Historical drilling has already expanded the mineralized envelope ten‑fold; the new program aims to test further northward and deeper extensions of the porphyry system.

Key Details

• Program Scope: 2,500 m total drill length focused on infill and resource expansion at KMZ.
• Current Inferred Resource (KMZ):
• 334.1 Mt @ 0.33 % CuEq → 2.42 M lb CuEq
• 0.15 % Cu, 0.26 g/t Au, 0.95 g/t Ag
• Historical Investment & Drilling: > $14 million invested; > 19,000 m drilled since 2020.
• Project Size & Access: > 90 km²; ~8 km to Omineca road and a 230‑kV power line.
• Geological Setting: Six‑kilometre porphyry copper‑gold trend with favourable geology, alteration, geochemistry and geophysics.
• Mineralized Extent Growth:
• Pre‑2021: ~350 m E‑W × 150 m N‑S × 400 m depth.
• Post‑2021 drilling: ~760 m E‑W × 600 m N‑S × 650 m depth.
• Open Directions: Open to the north, west, east, southeast and at depth.
• Key Historical Drill Intercepts (for context):
• 2021 – 316.7 m @ 0.79 % CuEq (1.17 g/t AuEq).
• 2022 – 328.0 m @ 0.64 % CuEq (0.95 g/t AuEq).
• 2023 – 305.5 m @ 0.59 % CuEq (0.87 g/t AuEq).
• 2024 – Hole KLI‑23‑069: 45.0 m @ 0.58 % CuEq (0.86 g/t AuEq) at 584 m depth, deepest mineralized interval to date.
• Recent Geophysics: 2024 ZTEM survey indicates substantial undiscovered porphyry mass north of the current drill footprint.
• Management Quote: “We’re very excited to return to Kliyul… mineralization remains open for expansion within and beyond the pit shell.” – Blaine Monaghan, President & CEO.
