Domestic Metals Completes Surface IP Geophysical Survey at Smart Creek and Announces Amendment to Warrant Terms of Unit Private Placement

VANCOUVER, British Columbia, March 13, 2026 (GLOBE NEWSWIRE) -- Domestic Metals Corp. (the “Company” or “Domestic Metals”) (TSXV: DMCU; OTCQB: DMCUF; FSE: 03E0) announces that an induced polarization (“IP”) geophysical survey at its Smart Creek copper-gold-silver project in Montana, has been completed by TMC Geophysics, who were engaged as part of ongoing mineral exploration by Domestic Metals. Fieldwork took place between February 6th and March 2nd, 2026 and consisted of 26 line-km of IP data acquired using the pole-dipole electrode array (Figure 1). The objective of the exploration program was to expand the footprint of previous IP geophysics collected by Rio Tinto to further delineate drill targets ahead of diamond drilling planned for Q2, 2026. Domestic Metals is currently modeling the new data and the results of this survey will be discussed in an upcoming news release.

“This new geophysical data will further help us in vectoring toward the center of porphyry mineralization that our geologists are confident is the source of high-grade metal results that we have seen from our work done at Smart Creek. With the funding from our last financing, we look forward to a successful drill campaign which is due to start in mid April”, says Gord Neal, CEO of Domestic Metals.

IP Geophysics and Porphyry CRD Mineral Exploration

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.

Amendment to Warrant Terms of Non-Brokered Private Placement

Domestic Metals reports an amendment to the warrant terms under the non-brokered private placement as announced on February 4, 2026, whereby the Company will place up to 12,500,000 units (the “Units”) at a price of $0.28 per Unit (the “Offering”) for gross proceeds of up to $3,500,000. Each Unit will consist of one common share of the Company (a “Share”) and one common share purchase warrant (a “Warrant”). Each whole Warrant now entitles the holder to acquire one additional Share of the Company for a period of three years from the date of issuance at a price of $0.40 per Share and there will be no acceleration of the Warrant expiry date.
