BARRANCO GOLD DEFINES HIGH-PRIORITY TARGETS THROUGH SOIL GEOCHEMISTRY ON KING PROPERTY

VANCOUVER, BC, June 17, 2025 /CNW/ - Barranco Gold Mining Corp. ("Barranco" or the "Company") (CSE: BAR) is pleased to announce that to date soil geochemistry results from its 100%-owned King Property have outlined multiple high-priority gold and copper anomalies, further validating the property's exploration potential. The King Property is located approximately 50 km south of Merritt, British Columbia, and consists of nine contiguous mineral claims totaling 3,456 hectares.

The soil sampling program collected to date included three major grids: the Main, South, and East Grids. 726 soil samples were collected systematically and analyzed using ICP- MS following aqua regia digestion. Sampling was carried out on grid lines spaced 100 m apart, with samples taken every 50 m along each line. The results delineate multiple strong gold and copper anomalies aligned with regional structures and intrusive contacts.

Soil Sampling Highlights

• Total samples: 726 soil samples collected
• Grid parameters: 100 m line spacing, 50 m sample spacing
• Gold anomalies: >100 ppb Au in Main and South Grids, with one 860 ppb
• Copper anomalies: >200 ppm Cu
• Anomalies may represent the interpreted northwest trending structures

The geochemical anomalies are spatially associated with fault zones and lithologic contacts between Osprey Lake Batholith rocks and quartz-feldspar porphyries of the Otter Intrusion. The data supports the presence of a hybrid porphyry-epithermal system, consistent with nearby productive mineral camps in southern British Columbia.

Next Steps

The Company will integrate soil anomalies with structural mapping and upcoming geophysical surveys to refine drill targets for Phase 2 exploration scheduled later in 2025.
