Vancouver, British Columbia--(Newsfile Corp. - August 12, 2026) - RED METAL RESOURCES LTD. (CSE: RMES) (OTC: RMESF) (FSE: I660) ("Red Metal" or the "Company") is pleased to announce that its wholly owned Chilean subsidiary, Minera Polymet SpA ("Polymet"), has entered into a renewable five-year lease agreement with Construcción Minería y Servicios Catalina Ltda. ("CMS Catalina"), a local small-scale (artisanal) mining company based in Vallenar, Chile, for the mining rights to its Irene and Margarita mineral concessions part of the Mateo property (together, the "Irene-Margarita Concessions" or the "Property"). The copper-gold Property is located approximately 15km east of Vallenar, Province of Huasco, in Chile's Atacama Region, and is separate from the Company's Carrizal Copper-Gold-Cobalt Property.
Highlights
Red Metal has leased the mining rights to its Irene and Margarita copper-gold concessions (approximately 106 hectares) near Vallenar, Chile to local artisanal miner CMS Catalina under a renewable five-year lease.
Polymet will receive a royalty of 10% of the gross value of all minerals extracted, with a guaranteed minimum payment of US$1,000 per month commencing in the third month.
Production is scheduled to ramp to a minimum of 2,500 tonnes per month after a three-month grace period.
Red Metal Resources President and CEO, Caitlin Jeffs, stated, "This lease brings a second small-scale mining agreement into our Chilean portfolio, generating royalty revenue from our Irene and Margarita concessions while supporting experienced local miners in the Vallenar district. It reflects our strategy of unlocking value from our Chilean assets at no risk to the Company, while we retain the right to explore our properties."
Irene-Margarita Property
The Irene-Margarita Property consists of three mining concessions located approximately 15km East of Vallenar in Chile's Atacama Region where ENAMI's processing facility for copper, gold and silver sulphide and oxide ore is located. The three concessions total approximately 106 hectares that the Company has held since 2009 as part of the Mateo property.
ENAMI investigated the Irene property in 1994. Work completed then included 490 metres of RC drilling in 4 surface drillholes and 220 metres of diamond drilling in 4 underground drillholes. According to ENAMI's reports from 1994 through 1997, approximately 16,144 tonnes of rock was mined with an average grade of 3.2% copper, 43.7 grams per tonne silver and 0.72 grams per tonne gold.
Between August 2009 and December 2010, small-scale test mining completed by the original vendor of the property at the Irene mine and delivered approximately 3,219 dry tonnes of ore to ENAMI at a weighted-average grade of 1.67% copper, for approximately 53.8 tonnes of contained copper. Gold and silver recoveries were reported for approximately 1,827 dry tonnes of the 3,219 tonnes delivered, and returned weighted-average grades of 0.33 g/t gold and 22.6 g/t silver. Gold and silver averages are calculated only over the lots for which ENAMI reported gold and silver in sulphide deliveries.

Terms of agreement
During an initial three-month grace period, CMS Catalina will work to obtain the required Chilean permits for production of up to 5,000 tonnes per month, authorization for an explosives' storage facility, and an approved exploitation and closure plan. During this period, CMS Catalina will be working on upgrading road access to the property in preparation for mining activities. Once the three-month grace period is over, there will be a 10% royalty on all sales amounts of ore to ENAMI with a minimum US$1,000 per month.
Following the grace period CMS Catalina expects a schedule of escalating mineral deliveries from 1,000 tonnes in the first month, to 1,500 tonnes in the second month, and to a minimum of 2,500 tonnes per month from the third month onward. If CMS Catalina fails to maintain the minimum production of 2,500 tonnes per month following ramp-up, Polymet may terminate the lease.
Red Metal retains the right to explore the Irene and Margarita concessions at all times.
