Vancouver, British Columbia--(Newsfile Corp. - July 16, 2026) - RED METAL RESOURCES LTD. (CSE: RMES) (OTC PINK: RMESF) (FSE: I660) ("Red Metal" or the "Company") is pleased to report preliminary results from the three-dimensional ("3D") induced polarization ("IP") survey announced on April 28th. The initial results over the southern block of its Carrizal Copper-Gold-Cobalt Property ("Carrizal" or the "Property"), near Vallenar in Chile's Atacama Region, returned clear chargeability anomalies across all six lines. Chargeability response aligns with two structures that have been sampled at surface and one that has been sampled and drill tested (see news release dated April 28, 2026).
Highlights
Chargeability trend defined across all six consecutive IP lines (Lines L0, L200, L400, L600, L800 and L1000), spaced 200 metres apart, traced across the southern block over approximately one kilometre and open along strike and at depth.
A secondary chargeability trend identified in the eastern portion of Lines L800 and L1000 at depth coinciding with a mapped and sampled vein.
Drilling completed so far on the Property has not tested the highest IP anomalies outlined in this survey.

IP Survey
The IP survey was completed by Geophysical Studies Chile as a true three-dimensional survey acquired through overlapping data blocks. The southern block comprises six survey lines (L0, L200, L400, L600, L800 and L1000), each approximately 2,000 metres in length and spaced 200 metres apart. The IP survey was designed to target the primary sulphide zone from 100m depth to 500m depth.
At the southern block, a chargeability high that coincides with historic drilling is spatially coincident with a zone of reduced resistivity. Coincident elevated chargeability and reduced resistivity is considered a favourable indicator of disseminated to semi-massive sulphide mineralization. The trend is interpreted to be continuous across all six lines, is open at depth on the northern lines of the block. A secondary chargeability trend is evident in the eastern half of the block most significantly in Lines L800 and L1000 at depth (Figures 2 through 7).
