Golden Cariboo outlines KM Uno zone at Quesnelle

Mr. J. Frank Callaghan reports GOLDEN CARIBOO CONFIRMS NEW DISCOVERY OF THE KM UNO ZONE, A PARALLEL ZONE AT THE QUESNELLE GOLD QUARTZ MINE PROPERTY AND PROJECT UPDATE Golden Cariboo Resources Ltd. has discovered the KM Uno zone, a mineralized structure parallel to the company's significant gold-silver bearing Halo zone discovery in 2024 at its Quesnelle Gold Quartz mine property. In addition, the company provides an update on exploration activities on the property, which is located four kilometres (2.5 miles) from Hixon, B.C. The KM Uno zone discovery is a significant parallel mineralized trend located approximately two kilometres southeast of the 2024 Halo zone discovery, with the Sunset trend positioned 1.4 kilometres to the west, effectively flanking the Halo zone in the middle. This configuration of parallel structures, KM Uno, Halo and Sunset, aligns with historical soil anomalies, resistivity highs and geochemical indicators, suggesting a cohesive, district-scale gold system (see the company's website for a map). Notably, these trends correlate strongly with the argillite-greenstone lithological contact visible in the property's geological mapping, a key feature that controls mineralization and is suggestive of the geological controls seen in major gold-producing districts across the Abitibi greenstone belt from Val d'Or to Timmins, where such contacts have been pivotal in defining extensive, high-grade deposits. The KM Uno zone, identified through targeted bedrock mapping and sampling, has yielded initial results of up to 1.1 grams per tonne gold and 8.0 g/t silver from mineralized volcanic subcrop, correlating with strong gold-silver-arsenic soil anomalies and geophysical features visible on the property's 2024 gold MMI (mobile metal ion) soil map. Similarly, the Sunset trend shows promising signs of mineralization, including potential extensions toward historical producers such as the Hixon Creek placer. With the Halo zone already demonstrating a 390-metre drilled strike length open for expansion, these parallel zones, enhanced by their association with the greenstone contact, underscore the property's potential for multiple interconnected gold-bearing structures. Highlights of the parallel zones include: KM Uno zone discovery: two kilometres (1.2 miles) southeast of the Halo zone, where initial samples from mineralized volcanic subcrop or angular float yielded 1.1 g/t gold with 8.0 g/t silver and 0.57 g/t gold with 3.3 g/t silver; these results align with airborne resistivity, ground conductivity anomalies and a strong gold-silver-arsenic soil anomaly; Halo zone: drilling and surface sampling confirm near-surface gold mineralization; key drill holes include: Discovery hole QGQ24-13: intersected 1.77 g/t gold over 136.51 metres (448 feet), as reported on Oct. 1, 2024; Hole QGQ24-20: reanalysis using PhotonAssay technology verified and increased gold grades by 5.9 per cent compared with fire assay, returning 0.56 g/t gold over 475.4 metres (1,560 feet) from 7.97 metres (26 feet) depth, including 236.88 metres (777 feet) of 1.06 g/t gold (announced Aug. 12, 2025); Sunset trend: located 1.4 kilometres (0.9 mile) west of the Halo zone, showing signs of mineralization; Buckley Creek: one kilometre (0.6 mile) north-northwest of the Discovery hole and two kilometres (1.2 miles) north of the Main zone shaft at Hixon Creek, where exploration aims to extend the Halo zone northward. "The assay results from the KM Uno zone, a structure parallel to our 2024 Halo zone discovery, mark a major milestone for the Quesnelle Gold Quartz mine property," said Golden Cariboo president Frank Callaghan. "These findings confirm our geological model and highlight the potential for multiple mineralized zones across the property. With the confirmed gold-silver discovery at KM Uno and the Halo zone's 390-metre strike length open for expansion, we're excited to continue exploring these promising gold systems." The spring drill program saw the completion of four surface diamond drill holes, QGQ25-21 to QGQ25-24, totalling 638.59 metres (2,095 feet), targeting strong quartz-carbonate vein stockwork along the argillite to greenstone contact and testing the northwestern continuity of gold-silver mineralization at the Halo zone. ALS Canada is nearing completion of PhotonAssay for gold and multielement analysis. Results are pending and will be released when finalized. Additional work completed during the summer exploration season includes reclamation, equipment maintenance, safety assessments and continued compilation of data from the large claim package staked in September, 2024. Delays in assay results were encountered due to a lost shipment of drill core and surface exploration samples by the freight carrier. The shipment was successfully recovered after an extended search period of one month. Further delays have been encountered due to the switchover to PhotonAssay analysis, a much more effective method in assaying coarse gold-bearing samples. Golden Cariboo appreciates the efforts made to resolve the matters and the company has been assured steps have been taken to ensure continued quality service and consistent tracking of future shipments.

About Golden Cariboo Resources Ltd. Golden Cariboo Resources 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 it at the northern 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 metres by 150 metres (less 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 kilometres (75 miles) toward the southeast along the same geological trend. As a sediment-hosted vein (SHV) deposit, the Spanish Mountain deposit is considered to belong to the epizonal orogenic subclass of gold deposits, which includes some of the world's largest deposits such as Muruntau (Uzbekistan) and Bendigo (Australia).
