Pacific Ridge drills at RDP copper-gold project

Vancouver, British Columbia--(Newsfile Corp. - August 7, 2026) - Pacific Ridge Exploration Ltd. (TSXV: PEX) (OTCQB: PEXZF) (FSE: PQW) ("Pacific Ridge" or the "Company") is pleased to announce that drilling is underway at its 100% owned RDP copper-gold project ("RDP" or the Project"), located in B.C.'s Golden Horseshoe at the southern end of the Toodoggone Mining District, 40 km to the west of the Company's 100% owned Kliyul copper-gold project (see Figure 1).

Pacific Ridge plans to drill ~ 3,000 m at the Day target, just one target area at RDP (see Figure 2), which returned 112.2m of 1.35% copper equivalent* ("CuEq") or 2.02 g/t gold equivalent** ("AuEq") within 405.0 m of 0.71% CuEq* or 1.06 g/t AuEq** in drill hole RDP-25-011 (see news release dated October 16, 2025).

"The Toodoggone Mining District has quickly emerged as Canada's hottest exploration district," said Blaine Monaghan, President & CEO of Pacific Ridge. "Over the last several years, numerous senior mining companies have made strategic investments or entered joint ventures. We are excited to return to RDP and test the interpreted porphyry centre at Day and further define last year's western magnetic lobe discovery."

2026 Exploration Program at RDP

The 2025 drill program at Day confirmed that the porphyry copper-gold-silver mineralization intersected in the eastern magnetic lobe is in an east-northeast-striking, steeply northward-dipping tabular body, and that the western magnetic lobe is also mineralized. This year's ~3,000 m drill program at Day will focus on testing the interpreted porphyry center between the western and eastern lobes and more fully defining the 2025 western lobe discovery (see Figures 3 and 4).

*CuEq = ((Cu%) x $Cu x 22.0462) + (Au(g/t) x AuR/CuR x $Au x 0.032151) + (Ag(g/t) x AgR/CuR x $Ag x 0.032151)) / ($Cu x 22.0462). **AuEq = ((Au(g/t) x $Au x 0.032151) + ((Cu%) x CuR/AuR x $Cu x 22.0462) + (Ag(g/t) x AgR/CuR x $Ag x 0.032151)) / ($Au x 0.032151). Commodity prices: $Cu = US$4.60/lb, $Au = US$2,600/oz., and Ag = US$30.00/oz. There has been no metallurgical recovery testing on RDP mineralization. The Company estimates copper recoveries (CuR) of 80%, gold recoveries (AuR) of 60%, and silver recoveries (AgR) of 60% 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.
