PACIFIC RIDGE ANNOUNCES FILING OF NI 43-101 TECHNICAL REPORT FOR KLIYUL COPPER-GOLD PROJECT

Pacific Ridge Exploration Ltd. has filed an independent technical report for the Kliyul copper-gold project on SEDAR+. The report was prepared in accordance with National Instrument 43-101 (Standards of Disclosure for Mineral Projects) in support of the initial mineral resource estimate for the Kliyul Main zone, which is just one target area at the company's 100-per-cent-owned Kliyul located in the prolific Quesnel terrane in north-central British Columbia.

Highlights:

• KMZ hosts 334.1 million tonnes grading 0.33 per cent copper equivalent, 0.15 per cent copper, 0.26 gram per tonne gold and 0.95 g/t silver in the inferred mineral resource category.
• KMZ contains 2.42 billion pounds CuEq, which include 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.
• KMZ is just one target area within a six-kilometre-long porphyry copper-gold trend, composed of favourable geology, geochemistry, alteration and geophysics.
• Mineralization at KMZ remains open for expansion within and beyond the resource reporting shell used to restrict the resource model.
• The company completed two drill holes, totalling 1,287 metres, at KMZ in 2025, which were focused on infill and resource expansion (see news release dated Sept. 11, 2025). Assays are pending.

Kliyul highlights:

• One hundred per cent owned by Pacific Ridge, the company has invested more than approximately $15.0-million and drilled more than 20,000 metres at Kliyul since 2020.
• Kliyul is over 90 square kilometres in size and is located in the prolific Quesnel terrane close to existing infrastructure, approximately eight km to the Omineca Resource Road and a 230-kilovolt high-voltage power line.
• A six-kilometre-long porphyry copper-gold trend, composed of favourable geology, geochemistry, alteration and geophysics, exists at Kliyul, but KMZ has been the focus since 2021.
• Drilling by Pacific Ridge has increased the mineralized extents of KMZ tenfold. Pre-2021, the mineralized extents measured approximately 350 metres east-west by approximately 150 m north-south by approximately 400-metre vertical depth. After the last round of drilling, the known mineralized extents measure approximately 760 m east-west by approximately 600 m north-south by approximately 650-metre vertical depth. KMZ remains open to the north, west, east and southeast and at depth.
• The best drilling result in 2021 was 316.7 metres of 0.79 per cent copper equivalent and 1.17 g/t gold equivalent (0.30 per cent copper, 0.70 g/t gold and 2.17 g/t silver) within 566.7 m of 0.51 per cent CuEq or 0.75 g/t AuEq (0.20 per cent copper, 0.44 g/t gold and 1.39 g/t silver) from KLI-21-037 (see news release dated Jan. 31, 2022).
• The best drilling result in 2022 was 328.0 m of 0.64 per cent CuEq or 0.95 g/t AuEq (0.25 per cent copper and 0.57 g/t gold) within 526 m of 0.49 per cent CuEq or 0.74 g/t AuEq (0.25 per cent copper, 0.57 g/t gold and 1.25 g/t silver) from KLI-22-050 (see news release dated Jan. 18, 2023).
• The best drilling result in 2023 was 305.5 m of 0.59 per cent CuEq or 0.87 g/t AuEq (0.23 per cent copper, 0.51 g/t gold and 1.22 g/t Ag) within 540.3 m of 0.44 per cent CuEq or 0.65 g/t AuEq (0.19 per cent copper, 0.36 g/t gold and 0.65 g/t silver) from KLI-23-054 (see news release dated Aug. 23, 2023).
• Drill hole KLI-23-069, the last hole of the 2023 drilling program, returned 45.0 m of 0.58 per cent CuEq or 0.86 g/t AuEq (0.38 per cent copper, 0.28 g/t gold and 2.20 g/t silver) within 570.0 m of 0.27 per cent CuEq or 0.40 g/t AuEq (0.14 per cent copper, 0.18 g/t gold and 0.99 g/t silver) (see news release dated Jan. 9, 2024). The 45-metre interval, at 584-metre downhole depth, is the deepest mineralized interval ever encountered at Kliyul and provides a northward and down plunge vector for a higher-grade porphyry centre at KMZ.
• Results of a 2024 ZTEM survey suggest that most of the KMZ porphyry system remains hidden and untested to the north.
• The company completed two drill holes, totalling 1,287 metres, at KMZ in 2025, focused on infill and resource expansion. Assays are pending.

There has been no metallurgical testing on Kliyul mineralization. The company estimates copper recoveries of 84 per cent, gold recoveries of 70 per cent and silver recoveries of 65 per cent based on the average recoveries from Kemess underground, Mount Milligan and Red Chris.

The technical information contained within the Kliyul highlights section has been prepared under the supervision of, and reviewed and approved by, Danette Schwab, PGeo, vice-president, exploration, of the company, a qualified person as defined by National Instrument 43-101 (Standards of Disclosure for Mineral Projects).

Estimation methods

The mineral resource estimate was completed using HxGN MinePlan 3-D software, and includes the estimation of copper, gold and silver grades into a block model (20 by 20 by 20 m) using an ordinary kriged method within a 0.1 g/t Au probability shell. Composites from a minimum of two drill holes were required for a block to be interpolated with a metal grade.

Prior to estimating block grades, potentially anomalous outlier grades were identified, and their influence on the grade model was controlled during interpolation through outlier restriction method. The two-metre composites were reviewed for each metal, and a restricted outlier strategy was employed to limit the influence of extreme metal grades to 60 m from a composite location. The threshold grade for gold was 4.5 g/t, 1 per cent for copper and 10 g/t for silver.

A base-case resource-constraining pit shell was built using HxGN MinePlan 3-D and inputs of metal prices ($2,600 (U.S.) per ounce Au, $4.60 (U.S.) per pound Cu and $30 (U.S.) per ounce Ag), metal recoveries (80 per cent Cu, 65 per cent Au and 65 per cent Ag), mining costs of $3.50 (Canadian) per tonne, processing costs of $7 (Canadian) per tonne, general and administrative costs of $3 (Canadian) per tonne, and pit slopes of 45 degrees. To assess the sensitivity to metal prices, additional shells were built using gold prices between $2,000 (U.S.) per oz and $3,200 (U.S.) per oz, and an additional copper price of $4.10 (Canadian) per lb and a silver price of $24 (Canadian) per oz.

Inferred mineral resources were assigned if a block were within 150 m of a drill hole.

Qualified person

The mineral resource estimate was completed by Susan Lomas, PGeo, of Lions Gate Geological Consulting Inc. with assistance from Bruce Davis, PhD, FAusIMM, each of whom is an independent qualified person under National Instrument 43-101 standards.

The technical information related to the mineral resource estimate in this news release has been reviewed and approved by independent QP Susan Lomas, PGeo.

LGGC completed an audit of the project drill hole database, a review of the quality assurance/quality control data for the assay results and a visit to the project site, and determined the drill hole data to be of sufficient quality to support the estimation of mineral resources.
