SIGNIFICANT GOLD ASSAYS REPORTED IN ROCK SAMPLES FROM BARRANCO GOLD'S KING PROJECT

VANCOUVER, BC, June 9, 2025 /CNW/ - Barranco Gold Mining Corp. ("Barranco" or the "Company") (CSE: BAR) is pleased to report results from its initial rock sampling program conducted at the 100%-owned King Property, located approximately 50 km south of Merritt, British Columbia, in the Quesnel Terrane. The King Property consists of nine contiguous mineral claims covering 3,456 hectares.

The Company's field team collected a total of 31 rock samples (grab and chip) from outcrops, float material, and altered zones across structurally controlled targets identified within the Main and Central Grid areas. Assays have returned encouraging gold values, with the highest result at 1.83 g/t gold, indicating a promising mineralized system.

Rock Sampling Highlights • 31 rock samples collected

• Sample 906575 (grab): 1.83 g/t Au, 97 ppm cu, 131 ppm Zn
• Sample 440683 (70 cm chip): 1.39 g/t Au, 118 ppm Cu
• Additional samples showed elevated arsenic, antimony, zinc, and lead
• Coordinates were recorded using handheld GPS units and archived in the GIS database
• Assays performed at Activation Laboratories (ActLabs), Ancaster, Ontario, using fire assay (FA-AA) and ICP-OES

Geological Context
The King Property is underlain by multi-phase intrusive rocks of the Osprey Lake and Pennask Batholiths, intersected by quartz-feldspar porphyry dykes of the Otter Intrusion. Mineralization occurs along NE- and NW-trending fault zones and is interpreted to reflect a porphyry-epithermal hybrid system similar to other known deposits in southern British Columbia, such as Copper Mountain and Brenda Mine.

Quality Assurance and Quality Control (QA/QC)
Barranco followed a robust QA/QC protocol. Sample batches included blanks, field duplicates, and certified reference materials. All data was reviewed internally to verify laboratory accuracy. Sampling was conducted under supervision of experienced geological staff.

Qualified Person
The technical content of this press release has been reviewed and approved by Derrick Strickland, P.Geo., a Qualified Person as defined under NI 43-101. Mr. Strickland is independent of the Company and authored the NI 43-101 Technical Report on the King Property dated November 23, 2023.

Cautionary Statements
Grab samples are selective and may not be representative of the overall mineralization on the property. Geochemical and geophysical surveys are preliminary and do not confirm the presence of economically recoverable mineral resources

Next Steps
Barranco is currently integrating sampling results into a 3D geological model to prioritize targets for Phase 2 exploration. Upcoming activities are expected to include:

• Expansion of soil grids • IP geophysics
• Detailed structural mapping and trenching
• Drill targeting in late 2025
