GOLDEN CARIBOO COMPLETES 754 M DRILL HOLE ENDING IN MINERALIZATION AND APPLIES TO REGISTER ADDITIONAL MINERAL CLAIMS

Golden Cariboo Resources Ltd.'s drill hole QGQ25-28 was completed on March 19, 2026, to a total length of 754.69 metres (2,476 feet), ending in mineralization approximately 12 m (39.37 ft) from Osisko Development Corp.'s claim boundary. The work was carried out at the company's Quesnelle gold quartz mine property, located approximately four kilometres northeast of Hixon and 50 kilometres southeast of Prince George, B.C.

The end of drill hole QGQ25-28 is located approximately 283 m (928.48 ft) beyond the end of drill hole QGQ25-25, which ended in mineralization. Assays are pending.

In addition, the company has applied to register an additional 1,283.59 hectares (3,171.82 acres) within and adjacent to its existing 94,899 ha (233,500.54 acres).

Frank Callaghan, president and chief executive officer of Golden Cariboo Resources, stated:

"QGQ25-28 appears to be a strong stepout hole, drilled to 754 m, that continued to encounter the same alteration and mineralization we've been seeing and ultimately ended in mineralization just 12 m from the Osisko Development claim boundary. The extension beyond QGQ25-25 and still finishing in mineralization supports the potential for a robust system. We are now looking forward to the assays as we continue to test the extent and continuity of the system. Additionally, we are looking to bolster our land package in preparation for future work on our regional targets and test the northern portions of the Spanish and Eureka thrust faults."

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 (New York Stock Exchange: ODV/TSX Venture Exchange: ODV), 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 kilometers (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 m (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 km (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 include some of the world's largest deposits such as Muruntau, Uzbekistan, and Bendigo, Australia.
