Domestic Metals Provides Project Update for Ongoing Field Level Exploration at the Smart Creek Project

Executive Summary

• Domestic Metals Corp. reports a systematic 40‑day surface exploration program at the Smart Creek Project in western Montana, identifying three high‑priority drill‑ready targets (Smart Creek, Sunrise Mine, Radio Tower) slated for drilling in Q4 2025–Q1 2026.
• Historic drilling at the Smart Creek target returned a notable intercept of 109.73 m @ 0.75% Cu and 18.74 g/t Ag; Sunrise Mine historic production includes up to 18.07 g/t Au, 4 % Cu and 0.105 % W.
• The company plans to employ novel exploration techniques (carbon‑oxygen isotope sampling, UV imaging of carbonate veins, portable XRF leakage analysis, potassium feldspar staining) to further delineate porphyry copper‑gold and CRD mineralization vectors.

Key Details

• Program Scope: 40‑day systematic mapping, sampling, and prospecting across Smart Creek, Sunrise, and Radio Tower zones to identify structural, lithological, alteration, and geochemical vectors toward porphyry Cu‑Au and carbonate replacement style (CRD) Cu‑Au‑Ag‑Zn mineralization.
• Target Prioritisation:
• Smart Creek Porphyry Target – drill‑ready; IP chargeability feature ~1,400 m × 600 m; historic intercept 109.73 m @ 0.75% Cu, 18.74 g/t Ag (SMCR0022).
• Sunrise Mine Target – historic production (1800‑1900) of ~12,500 oz Au; recent surface sample 4.22 g/t Au and 72.1 g/t Ag located ~1 km east, indicating a drill‑accessible porphyry Cu linkage.
• Radio Tower Target – 1,000 m × 1,300 m marbleized alteration zone with copper‑in‑soil anomaly and IP chargeability; considered stand‑alone CRD target.
• Planned Drilling: Multiple phases of exploration drilling anticipated to commence in late 2025 or early 2026 on all three high‑priority targets.
• Exploration Techniques Employed:
• Carbon‑oxygen isotope sampling for mapping alteration fronts in limestones.
• Ultraviolet light imaging of carbonate veins to detect base‑metal anomalies.
• Portable XRF leakage analysis for rapid geochemical screening.
• Potassium feldspar stain‑based detection methods for mineralization identification.
• Management Commentary: CEO Patricio Varas emphasizes that field evaluation is “on time and on budget” and expects the identified targets to host “economic bulk tonnage copper‑gold‑silver mineralization.”

Notable Quotes

“Rigorous and systematic field evaluation of the Smart Creek porphyry, Sunrise Mine porphyry/skarn and Radio Tower CRD and porphyry targets is progressing on time and on budget. The results will yield specific targets slated for multiple phases of exploration drilling beginning in late 2025 or early 2026.” – Patricio Varas, CEO

“The three high‑priority targets identified at the Smart Creek project each have large footprints based on magnetic and IP geophysics, alteration and lithological mapping, in addition to historic rock and soil surface geochemistry. Each of the three targets have stand‑alone potential to host economic bulk tonnage copper‑gold‑silver mineralization.” – Patricio Varas, CEO
