DRILLING UNDERWAY AT PACIFIC RIDGE'S KLIYUL COPPER-GOLD PROJECT

Drilling is under way at Pacific Ridge Exploration Ltd.'s 100-per-cent-owned Kliyul copper-gold project, located in British Columbia's prolific Quesnel terrane in north-central British Columbia.

Highlights:

• The planned 2,500-metre (m) drill program will be focused on infill and resource expansion drilling at the Kliyul Main zone (KMZ), just one target area at Kliyul.
• KMZ hosts 334.1 million tonnes (t) grading 0.33 per cent copper equivalent (CuEq), 0.15 per cent copper (Cu), 0.26 gram per tonne (g/t) gold (Au) and 0.95 g/t silver (Ag) in the inferred mineral resource category (see table 1 and the news release dated Aug. 6, 2025).
• KMZ contains 2.42 billion pounds (lb) CuEq, including 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 (see table 1 and the news release dated Aug. 6, 2025).
• Mineralization at KMZ remains open for expansion within and beyond the resource reporting shell used to restrict the resource model.

"We're very excited to return to Kliyul," said Blaine Monaghan, president and chief executive officer of Pacific Ridge Exploration. "Having just published an initial mineral resource estimate for KMZ, we are keen to restart drilling as it remains open for expansion within and beyond the pit shell."

Kliyul highlights:

• One hundred per cent owned by Pacific Ridge, the company has invested more than approximately $14.0-million and drilled more than 19,000 m at Kliyul since 2020.
• Kliyul is over 90 square kilometres (km) in size and is 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, comprising 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 m east-west by approximately 150 m north-south by approximately 400 m 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 m vertical depth. KMZ remains open to the north, west, east and southeast, and at depth.
• The best drilling result in 2021 was 316.7 m of 0.79 per cent CuEq* or 1.17 g/t gold equivalent (AuEq)** (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 the 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 the news release 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 the 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 the news release dated Jan. 9, 2024). The 45 m interval, at 584 m downhole depth, is the deepest mineralized interval ever encountered at Kliyul, and provides a northward and downplunge 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.

About Pacific Ridge Exploration Ltd.

The Kliyul copper-gold project, located in the prolific Quesnel terrane close to existing infrastructure, is the company's flagship project. In addition to Kliyul, Pacific Ridge's project portfolio includes the RDP copper-gold project, the Chuchi copper-gold project, the Onjo copper-gold project and the Redton copper-gold project, all located in B.C. The company would like to acknowledge that its B.C. projects are in the traditional, ancestral and unceded territories of the Gitxsan Nation, McLeod Lake Indian Band, Nak'azdli Whut'en, Takla Nation and Tsay Keh Dene Nation.

* CuEq equals ((Cu per cent) times Cu dollars times 22.0462) plus (Au (g/t) times AuR/CuR times Au dollars times 0.032151) plus (Ag (g/t) times AgR/CuR times Ag dollars times 0.032151)) divided by (Cu dollars times 22.0462).

** AuEq equals ((Au (g/t) times Au dollars times 0.032151) plus ((Cu per cent) times CuR/AuR times Cu dollars times 22.0462) plus (Ag (g/t) times AgR/CuR times $Ag times 0.032151)) divided by (Au dollars times 0.032151).

Commodity prices: Cu at $3.25 (U.S.) per lb; Au at $1,800 per ounce (oz); and Ag at $20 (U.S.) per oz.

There has been no metallurgical testing on Kliyul mineralization.

The company estimates copper recoveries (CuR) of 84 per cent, gold recoveries (AuR) of 70 per cent and silver recoveries (AgR) of 65 per cent based on average recoveries from Kemess Underground, Mount Milligan and Red Chris.

Factors: 22.0462 equal Cu per cent to lb per tonne; 0.032151 equals Au g/t to troy oz per tonne; and 0.032151 equals Ag g/t to troy oz per tonne.
