Vancouver, British Columbia--(Newsfile Corp. - April 2, 2026) - RED METAL RESOURCES LTD. (CSE: RMES) (OTC Pink: RMESF) (FSE: I660) ("Red Metal" or the "Company") is pleased to announce it has engaged Geophysical Studies Chile out of La Serena, Chile to complete an Induced Polarization (IP) survey over the Company's 100%-owned Carrizal Copper-Gold-Cobalt Project, located in Chile's Atacama Region.

• Target: Carrizal hosts a structurally controlled, vein-style, Iron Oxide Copper-Gold system. Veins have been identified and sampled over more than 12 km in strike length on surface. Drilling has tested 1.5 km of that veining to a depth of approximately 200 m. IP will target chargeability associated with sulphides at depths up to 500 m deep.

• Total work planned: two IP grids are planned to target two separate areas of veining. A northern target will consist of 10 lines, each 2.5 km in length for a total of 25 kms. A southwestern target will consist of 6 lines, each 2 km in length for a total of 12 km. The full survey will total 37 line kms.

Property highlights:

• Extensive Strike Continuity: Individual mineralized vein systems and mine workings have been mapped with strike lengths of up to 4.5 kilometres and over 12 kilometres of veining mapped and sampled.

• Surface sample confirmed potential economic grades: Historic surface sampling between 1996 and 2025 totaled 317 surface reconnaissance samples. Of the 317 samples collected, 178 returned copper grades over 1% copper, and 128 exceeded 2% copper and high grade copper values included 17.25%, 8.0% and 7.23%. For gold, 81 of the 317 samples returned grades above 0.5 g/t with 19 samples exceeding 2.0 g/t Au The highest grade samples were 8.4 g/t, 7.0 g/t and 5.4 g/t Au.

Management cautions that prospecting surface rock samples and associated assays, as discussed herein, are selective by nature and represent a point location, and therefore may not necessarily be fully representative of the mineralized horizon sampled.

Red Metal Resources President and CEO, Caitlin Jeffs, stated, "The Red Metal team's work to date has confirmed exceptional copper and gold grades over more than 12 km strike extent of veins on the Carrizal Property. By engaging Geophysical Studies Chile for this IP survey, we are taking the next step in preparing for the second phase of drilling and demonstrating the full extent of the copper-gold mineralization system."

With the Carrizal property we have the potential to unlock a significant IOCG system, and we invite our shareholders to join us on this exciting journey toward discovery."

Next steps for expanding knowledge and identifying priority targets at Carrizal:

• Structural and geological interpretation: Magnetics to map magnetite-bearing zones such as iron oxide copper-gold (IOCG) veins, breccia zones and related skarns; Induced Polarization geophysics to map sulphide concentrations and identify high-priority targets at depth.

• Advanced Targeting: Integration of 3D IP inversions of chargeability and resistivity data and LiDAR-assisted structural interpretation to refine drill targeting.

• Drill Planning: The combined information from structural interpretation, surface sampling, and IP showing possible sulphide mineralization at depth will be used to enhance confidence in drill targets. This will include expanding previously drilled targets and developing new ones.
