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 AgNew discovery of high-grade Critical Mineral trends 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” Highlight High-Grade Assay Results 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) Highlight, high-grade surface samples are provided in the table below: SampleEastingNorthingSampleSampleCopperGoldSilverID(m)(m)LithologyType(%)(g/t)(g/t)G0190013213455150400QuartziteOutcrop0.54930.412G0190073213655150392LimestoneOutcrop0.37710220.7G0190293267955148835SiltstoneOutcrop6.750.313173G0190313267905148864SiltstoneOutcrop19.650.877458G0190383268475148970SiltstoneSubcrop19.050.763582G0190823216405151163MarbleMine Dump1.83515.76.5G0190933200565149968Quartz VeinProspect Pit0.8750.226186G0190943208705147635SandstoneMine Dump0.0731.5222G0191513213615150388DolostoneOutcrop0.78715.0515G0192193268175148809LimestoneSubcrop2.720.167148G0192253268435148971SiltstoneOutcrop23.10.814424G0192353215415148233LimestoneMine Dump13.874.73810G0192383215455148248LimestoneMine Dump2.199.45359G0192983256315148102LimestoneMine Dump4.000.259161G0193533215925150732BrecciaTrench/Float2.6326.655.2G0193783202815149152BrecciaMine Dump0.3290.487157G0193793268305149873SiltstoneMine Dump8.420.137187G0194223253945148187SiltstoneMine Dump7.880.301134G0194273256105148683SiltstoneFloat12.350.747266G0194473235885150514quartz veinTest Pit0.1770.426105G0194653268025149930SiltstoneMine Dump16.10.0079.5 Table 1. Highlight rock sample assay results for the 2025 exploration program 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.

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. Figure 2.
