Golden Cariboo Resources Confirms Geological Model with Intercept of Gold-Mineralization in Recent Step-Out Drilling

May 27, 2025 – TheNewswire - Vancouver, Canada – Golden Cariboo Resources Ltd. (the “Company”) (CSE:GCC) (OTC:GCCFF) (WKN:A402CQ) (FSE:3TZ) announces that the most recent drill hole QGQ25-24 on the Halo zone at the Quesnelle Gold Quartz Mine property (the “Property”), 4 km (2.5 miles) from Hixon, BC, has intersected strong quartz-carbonate veining, including visible gold (“VG”) measuring 1.0 x 0.5 mm (for pictures see the Company’s website https://goldencariboo.com/latest-news). QGQ25-24 marks a 175 m (574 ft) step-out from previous drilling, confirming the Company's geological model of a strongly mineralized zone associated with the lithological contact between argillite and greenstones.

The footprint of all mineralization drilled at the Halo zone currently measures up to approximately 470 m by 290 m by 320 m (1540 ft by 950 ft by 1050 ft) and remains open along strike and towards depth, including approximately 620 m (2030 ft) of untested north-northwest strike towards the Pioneer limited past producer and 750m (2460 ft) of untested south-southeast strike towards the Main zone target at the past producing Quesnelle Quartz Mine. With its current step-out drill program, the Company is focusing on the strike expansion of the Halo zone mineralization.

Overall, the geological setting of the gold mineralization at the Company’s Quesnelle Gold Quartz Project shows strong similarities with the Spanish Mountain gold deposit, situated 120 km (75 miles) towards the southeast along the same geological trend. As a sediment-hosted vein (SHV) deposit, the Spanish Mountain deposit is considered to belong to the same subclass of orogenic gold deposits as some of the world’s largest deposits, including, e.g. Muruntau, Uzbekistan (>80 Moz) and Bendigo, Australia (>20 Moz) (Klipfel 2005).

Golden Cariboo’s President and CEO, Frank Callaghan, stated, “Each new drill hole in our step-out program continues to validate the strength and accuracy of our geological model. The consistency of mineralization we are seeing, particularly along the contact between argillite and greenstones, is highly encouraging. With visible gold now identified in 12 out of 13 holes, the potential scale of this zone is becoming increasingly evident. What makes this even more exciting is the near-surface nature of the mineralization and the property’s close proximity to infrastructure. These advantages position us well for future development and underscore the exceptional opportunity we have at the Quesnelle Gold Quartz Mine property.”

The latest drill hole, QGQ25-24, was drilled as a 175 m (574 ft) step-out towards the north of previous drilling and was set up at an azimuth of 016° and inclination of -45° to target a strong soil geochemical (MMI) gold anomaly related to the inferred surface expression of the contact between upper argillite and greenstones. It was collared in the upper argillite unit and intersected the lithological contact into the upper greenstone domain at a depth of 140.43 m (460.7 ft). Similar to all previous drill holes that intersected this contact, a strong stockwork of quartz-carbonate veins, including visible gold, is developed in association with brittle shear zones on both sides of the lithological contact (Photos 1 & 2). QGQ25-24 was terminated within the mineralized zone at a depth of 173.50 m (569.2 ft), due to technical issues.

Geological 3D modelling of the recent drill results (Figures 1 & 2) shows a general moderately steep westerly to west-southwesterly dip of lithological units in the area of the Halo zone discovery. A unit mainly comprising carbonaceous argillites (upper argillite) forms the stratigraphically highest member of the lithologies drilled at the Halo zone. The upper argillite overlies a package of greenstones, divisible into three domains, including upper greenstones (intermediate to mafic tuffs and volcanic sediments), variolitic greenstones (mainly variolitic and pillowed mafic to intermediate flows), and lower greenstones (fine-grained to aphanitic intermediate to mafic flows and volcaniclastics). The lower boundary of the greenstone package is marked by a lower argillite unit.

Gold mineralization, associated with multi-directional quartz-carbonate veining, which is related to multiple brittle shear zones, has been intersected throughout the greenstone package and to a lesser degree in the upper argillite. A zone of particularly high grades occurs within the upper greenstone domain in close spatial association with the contact between the upper argillite and the greenstone package. For the first time, this zone was intersected in its entirety in the top of drill hole QGQ24-20, resulting in an intercept of 1.45 g/t Au and 16.05 g/t Ag over 137.17 m (450.0 ft), including 4.61 g/t Au and 86.26 g/t Ag over 23.20 m (76.1 ft) (February 25, 2025 News Release).

The recent drill holes, QGQ24-21, QGQ25-23, and QGQ25-24, all intersected a visually strong quartz-carbonate vein stockwork along the argillite to greenstone contact (assays pending), including several occurrences of visible gold-bearing veins (e.g. May 13, 2025 News Release). The observations made in these drill holes correlate very well with the aforementioned high-grade zone, which marks significant step-outs from previous drilling along strike towards the north-northwest, while simultaneously proving the down-dip potential (Figures 1 & 2). To date, 12 out of 13 drillholes intersecting this high-grade zone at the Halo target showed visible gold mineralization.

About Golden Cariboo Resources Ltd.

Golden Cariboo Resources Ltd. 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 (NSE:ODV/TSXV:ODV), partly intertwined with them at the north end of the Cariboo Gold Project, and located along a favorable 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-kilometer (56 mile) trend from the Cariboo Hudson mine north to the Quesnelle Gold Quartz Mine property have recorded production and successful placer mining continues to this day.

Golden Cariboo’s Quesnelle Gold Quartz Mine property is 4 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 in conjunction with placer mining activities. Hixon Creek, which dissects the old workings, is a placer creek which has seen small-scale placer production since the mid 1860s.
