Domestic Metals Corp: Surface Sampling at Smart Creek Project Yields High-Grade Mineralization with up to 102 g/t Au, up to 23% Cu and up to 3810 g/t Ag

VANCOUVER, British Columbia, Jan. 08, 2026 (GLOBE NEWSWIRE) -- Domestic Metals Corp. (the "Company" or "Domestic") - (TSXV: DMCU; OTCQB: DMCUF; FSE: 03E) provides an exploration update. The company has received analytical results for 310 surface samples from the summer/Fall field campaign at the Smart Creek Project ("Project") in Montana. The program was designed to characterize known mineralized zones, refine drill target locations and identify new areas for follow-up exploration. The program has successfully identified high-grade gold, copper, and silver at the Smart Creek Project and has expanded all known targets and identified new high-grade copper, gold and copper mineralization across the property (Figures 1-4).

Gord Neal, CEO of Domestic Metals Corp. commented: "The 2025 field campaign was a success. These are the highest-grade field samples results I have ever been presented with in my career. In my experience these kinds of returns are harbingers of major economic discoveries. High grade mineralization has been identified in several locations, including new discovery areas. We look forward to firming up drill targets, deploying a targeted geophysics program followed by a diamond drill program in Q1, 2026"

Summary

• Domestic completed successful mapping, sampling and prospecting at the Smart Creek Project. The new data will be coupled with a geophysical (MT/IP) program in advance of drilling scheduled for Q1/2026.
• Rock sample assays from outcrops, historic trenching, mines and workings demonstrate high-grade gold, copper, silver and zinc and confirms the project is prospective for porphyry copper deposits, carbonate replacement deposits ("CRD"), skarn and exotic copper deposits.
• 39 samples (out of 310) exceed 0.5 g/t Au, 43 samples (out of 310) exceed 1 % Cu, 35 samples (out of 310) exceed 30 g/t Ag, 31 samples (out of 310) exceed 0.1% Zn.
• All targets (Sunrise Mine, Smart Creek, Radio Tower, Exotic Cu) are significantly expanded based on the results of the 2025 exploration program at the Project.

Domestic Metals 2025 Exploration Program Review

Domestic Metals completed a 40-day field campaign in August-September 2025 focused on geological mapping as well as several novel rock sampling techniques including: prospecting grab/composite grab samples and limestone sampling for trace metal vectoring. Sample subsets were also evaluated for alteration (slab and stain for potassic alteration related to porphyry mineralization), UV light evaluation (seeking metal contaminated calcite veins that can assist with vectoring toward CRD and porphyry mineralization), short-wave infrared evaluation (clay alteration vectoring) and portable XRF evaluation of iron oxide fracture fill (geochemical leakage vectoring technique to identify mineralization). Data from techniques other than the prospecting samples is currently being reviewed by Domestic Metals and will be the subject of future news release.

Smart Creek Porphyry Copper Project

The Smart Creek Copper Porphyry Project is a joint venture with Rio Tinto, where Rio will retain 40% of the asset. Rio drilled around 26 of the 40 permitted sites over 2.5 years as they vector toward the centre of the porphyry and at the Smart Creek Target returned 109.73 meter @ 0.75% Cu, which included 89 metres of 0.97% Copper (SMCR0022; see NR dated August 20, 2024)³

Exceptional rock sample results have been received from the 2025 field work, which highlights several opportunities including porphyry, skarn, CRD and structurally-controlled gold.

Of particular interest, the Smart Creek project area is underlain by geology that is highly prospective for CRD style deposits:

1. The Helena Fm silty limestones are superb reactive trap rocks.
2. Heat and fluid sources are abundant in this prolific western Montana porphyry belt.
3. The CRD signature alteration footprints are widespread at Smart creek (marble and manganese oxides).
4. Massive to semi-massive sulfides with excellent metal tenor have been sampled and mapped on the property.

Major deposits in the carbonate-hosted clan can yield high unit-value deposits with an excellent pedigree in the western unit states. Examples include the Copper Queen CRD deposit in the Bisbee Arizona District which yielded historic production of 53 Mt @ 6% Cu^1,2. The Domestic Metals technical team has extensive experience with this style of mineralization and will systematically explore for the CRD deposit style at the Project using modern toolkits.

The geochemical data is enhancing known target areas and is allowing Domestic Metals to identify targets for follow up diamond drilling scheduled for late Q1, 2026. New target areas have also been identified for target work-up.

All scientific and technical information in this news release has been reviewed and approved by Daniel MacNeil, P.Geo. Mr. MacNeil is a Technical Advisor to the Company and is a qualified person for the purposes of National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

Mr. MacNeil has verified the data disclosed in this news release, including the assay and test data underlying the information or opinions contained in this news release. Mr. MacNeil verified the data disclosed (including previously released Domestic data underlying the information disclosed) in this news release by reviewing imported and sorted assay data; checking the performance of blank samples and certified reference materials; reviewing the variance in field duplicate results; and reviewing grade calculation formulas. Mr. MacNeil detected no significant QA/QC issues during review of the data and is not aware of any sampling, recovery or other factors that could materially affect the accuracy or reliability of the drilling data referred to in this news release.

Samples were coarse crushed, fine crushed to 70% <2mm, split using a Boyd rotary splitter, pulverized up to 250g 85% <75micrometers. Analysis was conducted following 4-acid digestion (34 elements ICP-AES; ME-ICP61). Gold was analysed by 30g fire assay - AA finish (Au-AA23). Overlimits were evaluated by Au-GRA21, Ag-OG62, Cu-OG62, Zn-OG62 and Ag-GRA21. The company used ALS Labs in Reno, Nevada.

Samples with certified reference materials were inserted at intervals for ~5% of the submitted samples (15 standards total). QAQC results are satisfactory for the standards.
