Golden Cariboo Resources Ltd. (CSE:GCC) (OTC:GCCFF) (WKN:A402CQ) (FSE:3TZ) has announced the completion of core logging and sampling for diamond drill hole QGQ26-30, which targeted the western margin of the Halo zone at its flagship Quesnelle Gold Quartz Mine Property, located approximately 4 kilometers northeast of Hixon, British Columbia. The drill hole, completed to a final logged depth of 402.38 meters, successfully intersected broad intervals of intense sericite and carbonate altered volcanic rocks dominated by andesite tuff, along with distinctive chromium-mica (fuchsite) alteration. Mineralized quartz and quartz-carbonate veining was common throughout the hole and appears to be closely associated with gold mineralization.
Visible gold was observed on several occasions as irregular shaped flecks, typically less than 1 mm in size but reaching up to 3 mm, occurring adjacent to and within quartz-carbonate veins containing disseminated to cubic pyrite. Sulphide mineralization is dominated by pyrite with minor chalcopyrite and rare pyrrhotite, as well as localized semi-massive to massive sulphide intervals. Notably, visible gold measuring approximately 2 to 3 mm was identified in close proximity to subhedral to near-euhedral pyrite cubes up to 1 cm in size. Listwanite was intersected near the bottom of the hole between 384.77 m and 385.25 m, enveloped within an andesitic volcanosedimentary unit and surrounded by a 16.27 m halo of disseminated sulphide mineralization containing up to 20% replacement pyrite.
These initial observations from QGQ26-30 indicate gold mineralization exists at least 200 metres west of QGQ24-20, which reported 1.55 g/t gold with 16.05 g/t silver over 137.17 m (450.0 ft) as disclosed in a news release dated August 12, 2025. The new results suggest that mineralization continues to be open in all directions, highlighting the potential for significant lateral continuity and scale of the Halo system.
“This represents an important step out from previously defined mineralization and further demonstrates the lateral continuity and scale potential of the Halo system,” said Frank Callaghan, President and CEO. The expansion of the Halo zone is a critical development for Golden Cariboo as it continues to explore the property, which is bordered by Osisko Development and located along a favourable corridor adjacent to the Spanish and Eureka thrust faults over a 94,899 hectare area.
All samples from QGQ26-30 have been submitted to MSALabs in Prince George, British Columbia, for photon assay analysis, with results pending. The results will be included in Golden Cariboo’s upcoming Mineral Resource Estimate (MRE) as described in a news release dated July 22, 2026. This MRE will be a significant milestone for the company, providing a comprehensive assessment of the gold and silver resources on the property.

The Quesnelle Gold Quartz Mine property is historically significant, with over 101 placer gold creeks on the 90-kilometer trend from the Cariboo Hudson mine north to the property having recorded production. The property includes the Quesnelle Quartz gold-silver deposit, discovered in 1865, and its geological setting shows strong similarities with the Spanish Mountain gold deposit, situated 120 km 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 epizonal orogenic subclass of gold deposits, which include some of the world’s largest deposits such as Muruntau, Uzbekistan and Bendigo, Australia.
The expansion of the Halo zone by 200 meters west is a positive indicator for the potential size of the gold system at the Quesnelle Gold Quartz Mine property. With results pending, the company and its stakeholders await the assay data to quantify the grade and thickness of the mineralization encountered in QGQ26-30. This development underscores the ongoing exploration success at the property and reinforces the potential for a significant gold resource in the region.
