Pacific Ridge Completes Drilling at the Kliyul and RDP Copper-Gold Projects; Drilling at RDP Intersects 300 Metres of Continuous Copper-Sulphide Mineralization

The reported drill observations describe mineralization and alteration, but provide no 2026 assay grades.

Rhea-AI Summary

Pacific Ridge Exploration (PEXZF) completed 2026 drilling at its Kliyul and RDP copper-gold projects in British Columbia.

At RDP’s Day target, five holes totaled 3,010 metres. Drilling identified continuous copper-sulphide mineralization over lengths greater than 300 metres from vertical depths of approximately 170 metres. Two holes targeting an interpreted porphyry centre did not confirm that interpretation. At Kliyul’s previously untested M39 target, four holes totaled 1,524 metres; each encountered porphyry-style alteration and veining. The company said those features may indicate nearby copper-gold mineralization.

No 2026 assay grades were reported. Kliyul’s existing inferred resource at the Kliyul Main Zone, effective July 31, 2025, is 334.1 million tonnes grading 0.33% copper equivalent at a 0.20% copper-equivalent cutoff. That estimate predates the M39 drilling.

Vancouver, British Columbia--(Newsfile Corp. - September 24, 2026) - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) (FSE: PQW) ("Pacific Ridge" or the "Company") is pleased to provide an overview of the recently completed exploration programs at its 100% owned Kliyul copper-gold project ("Kliyul") and RDP copper-gold project ("RDP"). Kliyul is located in the prolific Quesnel terrane; RDP is located 40 km west of Kliyul at the southern end of the Toodoggone Mining District, one of Canada's hottest exploration districts (See Figure 1).

2026 Drilling Highlights

• At RDP, five diamond drill holes totaling 3,010 m were completed at the Day target. Two holes, RDP-26-015 and RDP-26-016, tested the interpreted porphyry centre, and three holes, RDP-26-017 through RDP-26-019, tested the western magnetic lobe (Figures 2 and 3).

• All drill holes intersected porphyry-style alteration, veining and porphyritic monzodiorite intrusions.

• Drill holes RDP-26-016, RDP-26-017 and RDP-26-019 confirmed continuous copper-sulphide mineralization (chalcopyrite +/- bornite) from vertical depths of approximately 170m over lengths greater than 300 m (Figure 4).

• At Kliyul, four diamond drill holes totaling 1,524 m were completed at the M39 target, a high-priority target that had never been drill tested before (Figure 5 and 6).

• Porphyry-style alteration, veining and porphyritic dioritic intrusions were encountered in every drill hole.

• Alteration and veining characteristics at M39 closely resemble those documented at the Kliyul Main Zone ("KMZ"), indicating potential proximity to porphyry copper-gold mineralization (Figure 7 and 8).

"The 2026 exploration programs generated important new geological and geophysical information at both Kliyul and RDP," said Blaine Monaghan, President & CEO of Pacific Ridge. "At RDP, drilling refined our understanding of the Day porphyry system and expanded the western magnetic lobe target area. At Kliyul, first-pass drilling at M39 provided valuable geological constraints for future targeting. We look forward to integrating the new datasets and reporting assay results as they become available."

RDP

Owned 100% by Pacific Ridge, RDP is over 100 km² in size and is located in the Golden Horseshoe at the southern end of the Toodoggone district, one of B.C.'s hottest exploration districts. The Company completed 3,010 m of drilling in five holes at the Day target this year.

Drill holes RDP-26-017, RDP-26-018, and RDP-26-019, totalling 1,958 m, tested the western magnetic lobe and followed up on drill hole RDP-25-014, which returned 130.8 m of 0.47% CuEq* or 0.70 g/t AuEq** (0.30%, 0.24 g/t Au or 1.34 g/t Ag) (see news release dated October 23, 2025) from a vertical depth of approximately 450m.

These drill holes confirmed continuous copper-sulphide mineralization (chalcopyrite +/- bornite) from vertical depths of approximately 170m over lengths greater than 300 m. Further, the results indicate that porphyry mineralization in the western magnetic lobe is not directly correlated with airborne magnetic vector inversion highs and that magnetic gradients and lows may also host mineralization, broadening the exploration search space at Day.

Drill holes RDP-26-015 and RDP-26-016, totalling 1,052 m, tested the interpreted porphyry centre between the eastern and western magnetic lobes. The holes encountered predominantly pyrite mineralization, low magnetic susceptibility, late mineral porphyry and intrusive breccia, and weak to moderate alteration, indicative of porphyry-halo alteration. Although the porphyry-centre concept was not confirmed, the drilling provided geological constraints that will help refine targeting between the eastern and western magnetic lobes.

Geophysical work at RDP included 11.7 line-km of IP surveying on seven lines over Day, 1.2 line-km on one line over Roy, and 283 line-km of airborne MT surveying over the southern portion of the property. These datasets will be integrated with drilling, geology, geochemistry, and existing magnetic models to refine follow-up targets.

Kliyul

Owned 100% by Pacific Ridge, Kliyul is over 90 km2 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. KMZ hosts 334.1 million tonnes ("Mt") grading 0.33% CuEq (0.15% copper, 0.26 g/t gold, and 0.95 g/t silver) (see Table 1) or 386 Mt grading 0.459 g/t AuEq (0.236 g/t gold, 0.142% copper, and 0.911 g/t silver) (see Table 2) in the Inferred Mineral Resource category and remains open for expansion.

In addition to KMZ, multiple untested targets remain along a six-kilometre porphyry copper-gold trend characterized by favourable geology, geochemistry, alteration, and geophysical signatures, including the M39 target area. M39 is associated with a one-km long copper and gold soil anomaly. The target hosts monzonite dykes, magnetite skarn, sodic alteration, and chalcopyrite mineralized quartz veins as well as two circular magnetic anomalies. The Company completed four diamond drill holes, totaling 1,524 m, at M39 this year.

Every drill hole intersected porphyry-style alteration and veining associated with porphyritic dioritic intrusions. The alteration and vein assemblages encountered at M39 are comparable to those in drill holes peripheral to the KMZ mineralization, including KLI-22-048A, located approximately 250 m laterally from the KMZ resource. Both areas contain widespread quartz-anhydrite-epidote-pyrite veins, barren early quartz veins and disseminated pyrite. These similarities indicate that drilling at M39 may have intersected the peripheral alteration footprint of a porphyry copper-gold system and support the potential for nearby mineralization.

Geophysical work at Kliyul included 10.7 line-km of IP surveying over the Bap Ridge target and 5.4 line-km over M39. The additional IP geophysics completed at M39 will assist in future drill targeting.

Notes for Tables 1 and 2 The effective date of the Mineral Resource estimate is July 31, 2025. The Mineral Resource was estimated using the Canadian Institute of Mining, Metallurgy and Petroleum(CIM), Definition Standards for Mineral Resources and Reserves, as prepared by the CIM Standing Committee and adopted by CIM Council. There has been no metallurgical testing on Kliyul mineralization. The Company estimates copper recoveries (CuR) of 80%, gold recoveries (AuR) of 65%, and silver recoveries (AgR) of 65% based on the reported recoveries from Mount Milligan. The mineral resource is constrained within a pit shell using metal recoveries of Cu 80%, Au 65% and Ag 65%, an exchange rate of 1.30 CAD: USD, mining cost of C$3.5/t, process cost of C$7.0/t, G&A costs of C$3.0/t, pit slopes of 45 degrees and metal prices of $Cu = US$4.60/lb, $Au = US$2,600/oz., Ag = US$30.00/oz. A fixed bulk density of 2.77 t/m3 was used for the estimation of tonnes. CuEq = Cu% + (0.6697*Au g/t) + (0.0077*Ag g/t). AuEq = Au + (1.4929 x Cu) + (0.0115 x Ag). Factors: 22.0462 = Cu% to lbs per tonne, 0.032151 = Au g/t to troy oz per tonne, and 0.032151 = Ag g/t to troy oz per tonne. The CIM definitions were followed for the classification of Inferred Mineral Resources. inferred blocks were assigned for blocks with one drill hole within 150 m. Mineral Resources are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves in the future. The MRE may be materially affected by considerations including, but not limited to, permitting, legal, sociopolitical, environmental issues, market conditions or other factors. All figures are rounded to reflect the relative accuracy of the estimate. Totals may not sum due to rounding as required by reporting guidelines.
