Domestic Metals posts surface sampling assays at Smart Creek Project, Montana
Domestic Metals Corp. [TSXV: DMCU; OTCQB: DMCUF; FSE: 03E] has provided an exploration update. The company has received analytical results for 310 surface samples from the summer/fall field campaign at the Smart Creek 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.
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.”
Highlights of high-grade assays: 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) and 19.05% Cu, 582 g/t Ag (Sample G019038).
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.
A totsl of 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 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.
The Smart Creek Copper Porphyry Project is a joint venture whereby Rio Tinto 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 metres at 0.75% Cu, which included 89 metres of 0.97% copper.
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: The Helena Fm silty limestones are superb reactive trap rocks; heat and fluid sources are abundant in this prolific western Montana porphyry belt. The CRD signature alteration footprints are widespread at Smart creek (marble and manganese oxides). Massive to semi-massive sulfides with excellent metal tenor have been sampled and mapped on the property.
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.
Domestic Metals is a mineral exploration company focused on the discovery of large-scale, copper and gold deposits in exceptional, historical mining project areas in the Americas.
The Company aims to discover new economic mineral deposits in historical mining districts that have seen exploration in geologically attractive mining jurisdictions, where economically favorable grades have been indicated by historic drilling and outcrop sampling.
The Smart Creek Project is strategically located in the mining-friendly state of Montana, containing widespread copper mineralization at surface and hosts 4 attractive porphyry copper, epithermal gold, replacement and exotic copper exploration targets with excellent host rocks for mineral deposition.
