Golden Cariboo Resources Ltd. Announces Active Drilling on Southern Extension of Halo Zone

Vancouver, B.C., Canada — November 10, 2026 — Leads & Copy — Golden Cariboo Resources Ltd. announced today that drilling is actively underway on a step-out hole designed to test the southern extension of the Halo zone at the Company's Quesnelle Gold Quartz Mine Property. The property, located approximately 50 kilometers southeast of Prince George, near Hixon in central British Columbia, recently had an inaugural Mineral Resource Estimate announced.

Drill hole QGQ26-35 is intended to evaluate the potential expansion of the Halo mineralized system towards the Main zone, situated about 700 meters to the southeast. Concurrently, the hole aims to delineate the western greenstone-argillite contact.

The drill has progressed beyond 150 meters, with Company geologists observing that the majority of the hole lies within the same sericite-altered volcanic tuff package, which is associated with significant mineralization in the Halo zone. Narrow mineralized extensional veins, characteristic of orogenic mineralization found elsewhere in the Halo deposit, have been observed throughout the core drilled so far. Assays are pending, and there is no guarantee that visually identified mineralization will yield economically significant gold values.

In addition to the ongoing drilling, the Company has completed drilling and logging of holes QGQ26-31 through QGQ26-33. Logging of hole QGQ26-34 is nearing completion. These holes were logged after the cutoff date for the Company's NI 43-101 Mineral Resource Estimate, dated October 31, 2026, and therefore are not included in the current resource model.

Technical information within the release was reviewed and approved by Sue Bird, an independent consultant and Professional Engineer (P.Eng.) registered with the Association of Professional Engineers and Geoscientists of the Province of BC (APEGBC). Bird is recognized as a Qualified Person under NI 43-101.

Golden Cariboo Resources Ltd. is focused on exploring its Quesnelle Gold Quartz Mine Property, which covers 96,183 hectares in a historic gold district in British Columbia. The property is situated along a 90-kilometer gold trend and is adjacent to Osisko Gold Group Inc.'s Cariboo Gold Project. The permitted 789-hectare portion of the property, located northeast of Hixon, contains the Quesnelle Quartz gold-silver deposit, first discovered in 1865. While historical mining focused on a smaller area, current exploration efforts suggest a significantly larger mineralized system.
