Golden Cariboo Advances Next Phase of Drilling at the Halo Deposit

(TheNewswire)

November 10, 2026 – TheNewswire - Vancouver, B.C., Canada – Golden Cariboo Resources Ltd. (the “Company”) (CSE:GCC) (OTC:GCCFF) (WKN:A402CQ) (FSE:3TZ) announces that drilling is actively underway on a strategically positioned step-out hole testing the southern extension of the Halo zone of the Company's recently announced inaugural Mineral Resource Estimate ("MRE") at it’s 100% owned Quesnelle Gold Quartz Mine Property located about 50 km southeast of Prince George, near Hixon in central British Columbia. Drill hole QGQ26-35 is designed to evaluate potential expansion of the Halo mineralized system toward the Main zone, located about 700m to the southeast, while simultaneously delineating the western greenstone-argillite contact.

The drill has now advanced beyond 150 metres (492 feet), with the majority of the hole observed by Company geologists to be within the same sericite altered volcanic tuff package associated with much of the Halo zone mineralization. Narrow mineralized extensional veins have been observed throughout much of the core drilled to date, an orogenic style of mineralization that has been encountered elsewhere within the Halo deposit. Assays have not yet been received, and there can be no assurance that visually identified mineralization will be associated with economically significant gold values.

The Company has also completed drilling and logging of holes QGQ26-31 through QGQ26-33, and logging of QGQ26-34 is nearly complete. These holes were logged after the cut-off date for inclusion in the Company's inaugural NI 43-101 MRE, dated October 31, 2026, and therefore do not form part of the current resource model.

About Golden Cariboo Resources Ltd.

Golden Cariboo Resources Ltd. is unlocking the potential of one of British Columbia's most historic gold districts through exploration of its Quesnelle Gold Quartz Mine Property. Encompassing 96,183 hectares (237,673 acres) along a prolific 90km gold trend that has yielded gold from more than 101 placer creeks, the Property occupies a strategic position bordering and partially interwoven with Osisko Gold Group Inc. (NYSE:OGG/TSXV:OGG) Cariboo Gold Project and lies along the highly prospective Spanish and Eureka thrust fault corridor.

Just 4 kilometres northeast of Hixon, the 789 hectare (1,950 acre) permitted portion of the Property hosts the historic Quesnelle Quartz gold-silver deposit, originally discovered in 1865 during the Cariboo Gold Rush. While early mining focused on a relatively small 150m x 150m (< 6 acre) footprint at the Main zone, Golden Cariboo's ongoing drilling and trenching programs are demonstrating the potential for a much larger mineralized system extending well beyond the limits of the historic workings.
