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.
