Rhea-AI Filing Summary

Red Metal Resources Ltd. reports that a geophysical crew has begun an induced polarization (IP) survey at its Carrizal Property in Chile. The program covers 37 line-kilometres on two grids and is designed to test a structurally controlled Iron Oxide Copper-Gold vein system.

The survey will collect chargeability and resistivity data to depths of about 500 m, complementing existing LiDAR and mapping work. Results are expected to help define new surface and subsurface targets and guide drill planning aimed at expanding previously drilled zones and testing newly generated copper, gold and cobalt targets.

Lidar, which stands for Light Detection and Ranging, is a technology that uses laser beams to create detailed, three-dimensional maps of the environment. It works like a sophisticated eye that measures distances by bouncing light off objects, helping machines see and understand their surroundings. For investors, lidar is important because it enables advancements in autonomous vehicles, robotics, and mapping, which can drive innovation and growth in related industries.

Red Metal Induced Polarization (IP) Survey Underway at Carrizal Property

VANCOUVER, BC, APRIL 28, 2026 - RED METAL RESOURCES LTD. ("Red Metal" or the "Company") (CSE: RMES, OTCPINK: RMESF, FSE: I660) is pleased to announce the 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.

Induced Polarization (IP) Survey at Carrizal

A survey crew from Geophysical Studies Chile out of La Serena, Chile, has mobilized to the Carrizal Property and an IP survey is now underway.

As previously outlined in the Company's press release dated April 2nd, 2026, the target at the Carrizal Property is a structurally controlled, vein-style, Iron Oxide Copper-Gold system, with surface veins running over 12 km in strike length and to known depths of approximately 200 m (https://www.redmetalresources.com/_resources/News%20Releases/20260204.pdf).

Work is underway at one of two proposed IP grids. A total of 37 line-kilometres of IP are planned in this phase of exploration, with a northern target consisting of 25 line-kilometres and a southwestern target consisting of 12 line-kilometres. As of April 22nd, crews have laid out 7.5 km of cable in the northern grid. 

The ongoing IP survey on the Carrizal Property will collect chargeability data associated with sulfide mineralization, reaching depths of approximately 500 m. The results of this survey will add significant information about the conductivity and sulfide content in surface veins as well as those yet unidentified at depth.

Red Metal Resources President and CEO, Caitlin Jeffs, stated, "We are excited that the geophysical crews have arrived on site and the IP survey has begun. 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:

 An ongoing 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.
