Vancouver, British Columbia--(Newsfile Corp. - April 22, 2026) - RED METAL RESOURCES LTD. (CSE: RMES) (OTC Pink: RMESF) (FSE: I660) ("Red Metal" or the "Company") is pleased to announce that a detailed analysis and interpretation of recent LiDAR survey data has been completed at its 100%-owned Carrizal Copper-Gold-Cobalt Property ("Carrizal" or the "Property"), located in Chile's Atacama Region. Red Metal is also pleased to announce that a geophysical crew from Geophysical Studies Chile has mobilized to site and begun working on an induced polarization (IP) survey spanning 37 line-kilometres at Carrizal.

Light Detection and Ranging ("LiDAR") Survey Results at Carrizal

The LiDAR survey is complete and results have been analyzed and interpreted. Previously identified geological structures representing proven mineralized veins were confirmed, and their limits extended in both directions. The detailed analysis of LiDAR data revealed several new zones containing parallel structures near well-documented and previously sampled veins on the Property. Numerous historic excavation pits have also been outlined, indicating the presence of mineralized structures. Previously unknown zones of interest have also been identified, sparking further field work to assess possible mineralization potential.

Highlights

LiDAR analysis has identified several potential features that warrant follow-up exploration and target development, including:

• 4 areas of dense historic artisanal workings with little to no previous surface sampling;

• 30 veins outlined, including 13 primary veins located near excavation pits having confirmed mineralization from surface sampling, that have been extended along strike beyond previously identified extents, and 17 secondary structures, including faults and potential veins that can be developed into more advanced targets with field testing;

• 4 new target areas highlighted by a combination of newly identified structures with high potential for ore mineralization, and/or by the density of historic artisanal workings.

The LiDAR survey, especially in an arid environment with minimal vegetation, provides a high-resolution, georeferenced digital elevation model (DEM) dataset that enhances the visibility of subtle geomorphological structures aiding in identification of minor faults and fine veining. Owing to minimal vegetation cover and limited soil development typical of desert terrains, LiDAR data allow for precise mapping of subtle topographic features, such as fault scarps, lineaments, paleochannels, lithological contacts, alteration zones, historic workings and other human activity which may not be readily discernible through conventional aerial photography or ground reconnaissance. Subtle structures revealed in high-resolution LiDAR surveys demonstrate the immense potential to identify previously unknown structures that may represent fine faults and ore fluid pathways.

Red Metal Resources President and CEO, Caitlin Jeffs, stated, "LiDAR analysis and interpretation, in conjunction with previous surface observations and sampling, has successfully identified new vein sets and extensions to previously delineated mineralized veins. New targets are being developed from this exploration work, strengthening the potential for further copper, gold, and cobalt mineralization to be discovered."

Next Steps
The next steps to further develop the priority targets at Carrizal:

• IP survey, including 3D inversions of chargeability and resistivity data to complement LiDAR and mapping, generating both surface and subsurface targets.

• Drill Planning: Results will be used to generate a drill program targeting the expansion of previously drilled targets, along with newly developed targets. The combined information from the LiDAR structural interpretation, surface grab sampling and IP survey outlining potential sulfide mineralization up to 500 m depth will be incorporated into high confidence drill targets.
