Domestic Metals Corp: Domestic Metals Expands Targeting Initiative at Smart Creek Copper Project

VANCOUVER, British Columbia, March 06, 2026 (GLOBE NEWSWIRE) --

Domestic Metals Corp. (the "Company" or "Domestic Metals") - (TSXV: DMCU; OTCQB: DMCUF; FSE: 03E0) 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 January 8, 2026) at the Smart Creek Copper Project. Surface rock sampling and surface geological mapping has increased the size of each of these target areas and confirms the potential for high-grade copper, gold and silver mineralization in the porphyry and epithermal environments as well as confirms the presence of related Carbonate Replacement Deposit style mineralization. The Company has now confirmed the presence of each of these styles of mineralization exposed at surface at Smart Creek and is now planning follow up diamond drilling scheduled for April 2026.

Summary of High-Grade Assay Results from 2026 Exploration

• 102 g/t Au (Sample G019007)
• 74.7 g/t Au, 13.8% Cu, 3810 g/t Ag (Sample G019235)
• 30.4 g/t Au (Sample G019001)
• 26.6 g/t Au (Sample G019353)
• 23.1% Cu, 424 g/t Ag (Sample G019225)
• 19.65% Cu, 458 g/t Ag (Sample G019031)
• 19.05% Cu, 582 g/t Ag (Sample G019038)
  

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

Smart Creek Copper Porphyry Target

Previous exploration drilling is concentrated at the Smart Creek target where surface alteration and mineralization is 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 (Figure 1). 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 center westward of the historical drilling footprint (Figure 1).

Sunrise Porphyry Copper Target

Domestic Metals has identified mineralized porphyry dykes approximately 1 kilometer east of the past producing Sunrise Mine (see NR dated September 11, 2025; Figure 1). 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 upcoming 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 (Figure 1). These high-grade copper-gold-silver lenses have been prioritize 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.
