GOLDEN CARIBOO RESOURCES QGQ26-30 EXPANDS HALO ZONE 200M

Golden Cariboo Resources Ltd. has completed core logging and sampling for diamond drill hole QGQ26-30, which targeted the western margin of the company's Halo zone at its flagship Quesnelle gold quartz mine property, located approximately four kilometres (2.5 miles) northeast of Hixon, B.C. The Halo zone forms part of the company's broader mineralized corridor at the property and has become a significant focus of continuing exploration.

Drill hole QGQ26-30, completed to a final logged depth of 402.38 metres (1,320.14 feet), intersected broad intervals of intense sericite and carbonate altered volcanic rocks dominated by andesite tuff, along with distinctive chromium-mica (fuchsite) alteration. Mineralized quartz and quartz-carbonate veining was common throughout the hole, and appears to be closely associated with gold mineralization. Visible gold was observed on several occasions as irregular shaped flecks, typically less than one millimetre in size but reaching up to three mm, occurring adjacent to and within quartz-carbonate veins containing disseminated to cubic pyrite. Sulphide mineralization is dominated by pyrite with minor chalcopyrite and rare pyrrhotite, as well as localized semi-massive to massive sulphide intervals. Notably, visible gold measuring approximately two to three mm was identified in close proximity to subhedral to near-euhedral pyrite cubes up to one centimetre in size. Listwanite was intersected near the bottom of the hole between 384.77 m and 385.25 m, enveloped within an andesitic volcanosedimentary unit and surrounded by a 16.27-metre halo of disseminated sulphide mineralization containing up to 20 per cent replacement pyrite. These initial observations from QGQ26-30 indicate gold mineralization exists at least 200 metres west of QGQ24-20, which reported 1.55 g/t gold with 16.05 g/t silver over 137.17 m (450.0 ft) (news release dated Aug. 12, 2025) and suggests mineralization continues to be open in all directions.

"This represents an important stepout from previously defined mineralization and further demonstrates the lateral continuity and scale potential of the Halo system," said Frank Callaghan, president and chief executive officer.

All samples from QGQ26-30 have been submitted to MSALabs in Prince George, B.C., for photon assay analysis, with results pending. The results will be included in the Golden Cariboo's coming mineral resource estimate as also described in the news release dated July 22, 2026.

About Golden Cariboo Resources Ltd.

Golden Cariboo is rediscovering the Cariboo gold rush by proceeding with highly targeted drilling and trenching programs on its Quesnelle gold quartz mine property, which is bordered by Osisko Development, partly intertwined with them at the north end of the Cariboo gold project, and located along a favourable corridor adjacent to the Spanish and Eureka thrust faults over a 94,899-hectare (234,501-acre) area. Historically, over 101 placer gold creeks on the 90-kilometre (56 mile) trend, from the Cariboo Hudson mine north to the Quesnelle gold quartz mine property, have recorded production with successful placer mining continuing to this day.

Golden Cariboo's Quesnelle gold quartz mine property is four kilometres (2.5 miles) northeast of, and road accessible from, Hixon in central British Columbia. The property includes the Quesnelle quartz gold-silver deposit, which was discovered in 1865 and developed over a footprint of about 150 m by 150 m (fewer than six acres) at the Main zone straddling Hixon Creek. Over all, the geological setting of the gold mineralization at the company's Quesnelle gold quartz mine property shows strong similarities with the Spanish Mountain gold deposit, situated 120 km (75 miles) toward the southeast along the same geological trend. As a sediment-hosted vein deposit, the Spanish Mountain deposit is considered to belong to the epizonal orogenic subclass of gold deposits, which include some of the world's largest deposits such as Muruntau, Uzbekistan, and Bendigo, Australia.
