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

Vancouver, British Columbia--(Newsfile Corp. - April 28, 2026) - RED METAL RESOURCES LTD. (CSE: RMES) (OTC Pink: RMESF) (FSE: I660) ("Red Metal" or the "Company") 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 2^nd, 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. ...).

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 22^nd, 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."
