Vancouver, Canada — June 17, 2025 — NewsWall — Golden Cariboo Resources Ltd. (CSE:GCC) (OTC:GCCFF) (WKN:A402CQ) (FSE:3TZ) has provided an update on its PhotonAssay™ orientation study, which utilizes advanced assay technology for precise gold exploration results.

The company has contracted ALS Canada Ltd. to conduct an orientation study using Chrysos PhotonAssayTM technology to analyze gold content in rock and drill core samples from its Quesnelle Gold Quartz Mine property, located near Hixon, British Columbia. This study aims to improve the nugget effect and assay turnaround times.

ALS Canada Ltd. has confirmed receipt of samples from drill hole QGQ24-20, which previously reported 0.71 g/t gold with 6.96 g/t silver over 341.96 m. Preparation is complete for samples from drill hole QGQ24-21, which showed visible gold grains. Photon assay may replace fire assay for gold quantification in future samples.

Frank Callaghan, President and CEO of Golden Cariboo Resources Ltd., stated that the company is committed to innovative exploration techniques and looks forward to sharing the findings.
