MULTIPLE LARGE CHARGEABILITY FEATURES SUPPORT PORPHYRY/CRD TARGETS AT SMART CREEK PROJECT, MONTANA

A recently completed induced polarization (IP) geophysical survey at Domestic Metals Corp.'s Smart Creek copper-gold-silver project in Montana identified chargeability features that support the project's target potential. The newly enhanced targets include extensive porphyry copper style zones in addition to carbonate replacement (CRD)/skarn copper-gold silver mineralization. The IP chargeability features of interest are widespread, coincident with previously established alteration footprints and high-grade sampling carried out by the company (see news release dated Jan. 8, 2026). The IP targets are interpreted to represent previously untested magmatic-hydrothermal sulphides related to copper porphyry, CRD- and/or skarn-related sulphides. These results support Domestic Metals' geologically and geochemically based target initiatives and represent priority 1 drill targets at the Smart Creek project.

"The Smart Creek project continues to give us better than expected results. These new geophysical data will further help us in vectoring toward the center of porphyry and CRD target mineralization. Our geologists have developed targets based on the high-grade metal results that we have seen from our work done at the Smart Creek project; these targets are now refined based on the new IP data. With the funding from our last financing, we look forward to a successful drill campaign which is due to start mid-April," commented Gord Neal, chief executive officer of Domestic Metals.

IP geophysics results

Domestic Metals commissioned TMC Geophysics to carry out an induced polarization (IP) survey on its Smart Creek project situated 70 kilometres southeast of Missoula, Mon., United States. The fieldwork took place between Feb. 6 and March 2, 2026, and consisted of 26 line kilometres of IP data acquired using a pole-dipole electrode array.

The 2026 IP geophysical survey at Smart Creek delineated chargeability features that are interpreted to represent sulphide mineralization in the subsurface potentially related to porphyry copper, and CRD and/or skarn mineralization that has never previously been drill tested on the property. Chargeability features were delineated at Smart Creek, Smart Creek Exotic, Sunrise and Radio Tower targets, substantially increasing Domestic's confidence in previously identified drill targets in these areas (Table 1).

Smart Creek target

The 2026 IP geophysical survey includes a single line (Line 6) approximately 350 metres west of historical data collected by Rio Tinto in 2021. This line demonstrates that the chargeability feature extends farther west than previously known and represents a high-priority drill target with potential for porphyry copper style mineralization.

Smart Creek exotic target

A single line (Line 5) collected to infill the 2021 Rio Tinto IP geophysical survey was collected at the Smart Creek exotic target. This line enhanced the resolution of the previous survey and demonstrates a 2.5-kilometre-long IP chargeability feature running northwest to southeast from Smart Creek to southern Smart Creek exotic targets. The anomaly extends west of previous historic drilling on the property. This feature represents a second high-priority porphyry copper drill target for Domestic Copper.

Sunrise target

The 2026 IP geophysical survey included four north-northeast-oriented lines in and around the Sunrise target, which reveal a chargeability feature of interest to the north of Sunrise and also delineates a chargeability feature south of the Sunrise mine. The southern anomaly continues southward toward the Radio Tower target area. This feature immediately south of the Sunrise mine represents a high-priority drill target for Domestic Metals with the potential for copper porphyry and skarn mineralization.

Radio Tower target

The 2026 IP geophysical survey included four lines that transect the Radio Tower target area. The southern portions of these lines identified a large, 1.5-kilometre-long-by-1.4-kilometre-wide chargeability feature that is coincident with high-grade surface copper-gold-sliver CRD style mineralization identified in the 2026 surface geochemical sampling program. This feature has potential to host CRD and porphyry style copper-gold-silver mineralization and represents a high-priority drill target.

IP geophysics and porphyry/skarn/CRD mineral exploration

The 26 line km IP survey grid consisted of six irregularly spaced profiles of 2.8 km to 5.8 km in length with survey station markers/reference points every 25 m along these profiles. Locations were captured using a Garmin GPS non-differential receiver in the UTM12N_WGS84 co-ordinate system. The pole-dipole (dipole-pole) array was chosen for the IP survey on the Smart Creek project. The nominal A-spacing between the electrodes was set to 100 metres and a maximum of 15 dipoles were read.

IP geophysics is used to obtain chargeability and resistivity values (rock properties) which can provide insights into the distribution of sulphides and hydrothermal alteration in the subsurface at Smart Creek. Resistivity and chargeability features identified in the subsurface can provide a means of independently verifying targets constrained from surface geology and geochemistry. Domestic Metals will combine these new IP geophysical data with previously collected data to investigate the potential for new porphyry and carbonate replacement mineralization in the subsurface at Smart Creek project.
