DOMESTIC METALS EXPANDS TARGETING INITIATIVE AT SMART CREEK COPPER PROJECT

Domestic Metals Corp. has expanded its exploration targeting budget based on high-grade copper, gold and silver results from the company's recently completed surface exploration program (see news release dated Jan. 8, 2026) at the Smart Creek copper project. Surface rock sampling and surface geological mapping have increased the size of each of these target areas, and confirm the potential for high-grade copper, gold and silver mineralization in the porphyry and epithermal environments, as well as confirm the presence of related carbonate replacement deposit style mineralization. The company has confirmed the presence of each of these styles of mineralization exposed at surface at Smart Creek, and is planning follow-up diamond drilling scheduled for April, 2026.

Summary of high-grade assay results from 2026 exploration:

• 102 grams per tonne gold (sample G019007);
• 74.7 g/t gold, 13.8 per cent copper and 3,810 grams per tonne silver (sample G019235);
• 30.4 g/t Au (sample G019001);
• 26.6 g/t Au (sample G019353);
• 23.1 per cent Cu and 424 g/t Ag (sample G019225);
• 19.65 per cent Cu and 458 g/t Ag (sample G019031);
• 19.05 per cent Cu and 582 g/t Ag (sample G019038).

For additional details regarding the surface sampling results at Smart Creek, please see news release dated Jan. 8, 2026.

Smart Creek copper porphyry target

Previous exploration drilling is concentrated at the Smart Creek target where surface alteration and mineralization are consistent with the distal porphyry environment. Domestic Metals has leveraged historical drilling data and newly collected surface geological and geochemical data to establish a robust exploration drilling target west of the historical drilling footprint. In addition, exotic copper mineralization south of the Smart Creek target (Smart Creek Exotic copper) appears to be superimposed on distal copper porphyry-related mineralization, suggesting there is the potential for a second porphyry centre westward of the historical drilling footprint.

Sunrise porphyry copper target

Domestic Metals has identified mineralized porphyry dikes approximately one kilometre east of the past-producing Sunrise mine (see news release dated Sept. 11, 2025). These mineralized porphyry intrusions are exposed at surface and are interpreted to represent the top of a new porphyry system at Smart Creek. The depth extent of this surface mineralization will be tested as part of the coming diamond drill program at Smart Creek.

Radio Tower carbonate replacement targets

The 2025 surface exploration program has identified several previously unrecognized semi-massive and massive sulphide CRD lenses exposed at surface internal to the Radio Tower alteration footprint. These high-grade copper-gold-silver lenses have been prioritized for drill delineation and will be tested after a second round of permitting is complete for the project. Additional mapping and sampling will be conducted in the spring to further derisk these targets.

Marketing agreement

The company has entered into an agreement with Machai Capital Inc. dated Feb. 27, 2026, pursuant to which Machai will provide public awareness activities and deploy a comprehensive digital media marketing program, including multiplatform digital campaigns, social media amplification and targeted investor communications.
