Red Metal Resources Provides Update on Results of Mapping Program on Its Carrizal IOCG Property

Rhea-AI Summary

Red Metal Resources (RMESF) has reported exceptional results from its mapping and sampling program at the Carrizal IOCG Property. The program focused on extending previously identified veins spanning approximately 15km from the historic Carrizal Alto mine. Notable findings include high-grade samples of 17.3% Cu with 5.0 g/t Au, 7.1% Cu with 8.4g/t Au, and 6.8% Cu with 7.0 g/t Au in the South Theresa Zone. All 71 samples collected showed over 1% Cu content, with 41 samples exceeding 4% Cu and 22 samples containing more than 1g/t Au. The sampling program revealed higher gold-to-copper ratios in the South Theresa zone compared to the main Farellon structure, particularly highlighting the gold potential in the previously untested southwestern vein extensions.

Positive

• Exceptional high-grade sample results with up to 17.3% copper and 8.4 g/t gold
• All 71 samples showed significant mineralization with over 1% copper content
• 41 samples exceeded 4% copper and 22 samples contained more than 1g/t gold
• Program revealed untapped potential in previously untested southwestern vein extensions
• Results indicate potential for a world-class IOCG system

Negative

• Results are from surface sampling only and may not be representative of the entire mineralized horizon
• Southwestern extension of veins remains untested by drilling
• Limited sampling has been conducted in certain areas

Vancouver, British Columbia--(Newsfile Corp. - June 5, 2025) - RED METAL RESOURCES LTD. (CSE: RMES) (OTC Pink: RMESF) (FSE: I660) ("Red Metal" or the "Company") is pleased to announce it has received results from the sampling and mapping work program, which was designed to follow up on and extend previously identified veins that make up approximately 15km of veining extending along strike from the historic Carrizal Alto mine.

Highlights

• Significant sample returns of 17.3% Cu with 5.0 g/t Au, 7.1% Cu with 8.4g/t Au, and 6.8% Cu with 7.0 g/t Au in the South Theresa Zone
• Clear definition of veins in the South Theresa zone, which show higher gold to copper ratios than the main Farellon structure
• 71 samples collected, all samples returned higher than 1% Cu, 41 returned greater than 4% Cu, and 22 returned greater than 1g/t Au

Red Metal Resources President and CEO, Caitlin Jeffs, stated, "These outstanding results, with grades up to 17.3% copper and 8.4 g/t gold, underscore Carrizal's potential as a cornerstone asset in the global copper-gold sector. With the Carrizal Property, we have the potential to unlock a world-class IOCG system, and we invite our shareholders to join us on this exciting journey toward discovery."

The 2025 mapping and sampling program has highlighted the higher-grade gold potential of the southwestern extension of the veins that have never been drill tested and only had limited sampling.

Sampling of the Armonia vein as it extends from the historic Carrizal Alto mine onto Red Metal's Carrizal Property continues to highlight the 2.5 kilometeres of veining that has not been drill tested.
