Domestic Metals to Commence Drill Program at Smart Creek Project, Montana

Exploration Programs

Domestic Metals to Commence Drill Program at Smart Creek Project,

Montana

Vancouver B.C., August 6, 2026

Domestic Metals Corp. (the “Company” or “Domestic Metals”) - (TSXV: DMCU; OTCQB: DMCUF; FSE:

03E0) announces it will commence a fully permitted and funded 9,000m drill program late August 2026,

targeting high-grade porphyry copper style mineralization at the Smart Creek Project in Montana,

located 50km northwest of the Butte Mine Complex (the Butte District production is credited at 24.8B

pounds of copper between 1180-20041) and occupies a similar geological setting. The drill program is

designed to test numerous high-priority targets identified through the Company's 2025–2026

exploration campaign.

Program Highlights

• Up to 9,000 meters of diamond drilling across an estimated 6-8 holes

• Program fully funded through the Company’s existing treasury

• Targets defined by IP geophysical program, surface sampling, results of historical drill program

and 3D computer modeling to help vector toward main mineralized sources on the property

• First assay results are expected 6-8 weeks following the start of the drilling

"This program represents the culmination of nearly two years of systematic exploration at Smart Creek,"

said Gordon Neal, CEO and Director of Domestic Metals. "We've refined our target model significantly

since taking on the project, and the drill plan is designed to vector toward the center of porphyry and

CRD target mineralization. Our geologists have developed targets based on the high-grade surface rock

sampling results and new IP geophysical data. We believe Smart Creek is prospective for porphyry copper

as well as copper-gold-silver enriched carbonate replacement deposits (CRD) and we're excited to finally

put the drill bit to these targets."

Project Overview

The Smart Creek Copper Porphyry Project, acquired in August 2024, is a joint venture with Rio Tinto,

where Rio will retain 40% of the asset. The project covers 8,000 hectares and is located 50km northwest

of the Butte District and occupies a similar geological setting. Smart Creek is considered prospective for

porphyry copper as well as copper-gold-silver enriched carbonate replacement deposits (CRD).

Rio Tinto previously drilled 26 of 40 permitted sites investigating the distribution of copper porphyry

mineralization at the Smart Creek Target where the best hole returned 109.73 meter @ 0.75% Cu, which

included 89 metres of 0.97% Copper (SMCR0022; see news release dated August 20, 2024).

Modern exploration by Domestic since 2024 has focused on identifying the broader mineralized system,

using a combination of:

• Detailed geological mapping and structural interpretation

• Reconnaissance mapping and sampling, Assay results at the high-priority Sunrise Target at the

Smart Creek Project returned 4.26 g/t Au (news release dated March 3, 2025)

• 2025 summer field program. Sampling returned high grade results: 102 g/t Au with 23.1% Cu

and 3,810 g/t Ag. (news release dated January 8, 2026)

• IP Geophysics with multiple new large-scale targets identified. IP chargeability features are

coincident with previously established alteration footprints and high-grade sampling (news

release dated January 8, 2026 and Figure 1 below). Results support Domestic Metals’

geologically and geochemically based target initiatives and represent Priority 1 drill targets at

the Smart Creek Project. (news release dated April 2, 2026)

• Compilation and digitization of historic drill hole and assay data

This work has outlined two priority drill target areas, described below.

Drill Target Areas

Smart Creek Target – Phase 1

The 2026 IP Geophysical survey demonstrated that the chargeability feature extends further west than

previously known and represents a high-priority drill target with potential for porphyry copper style

mineralization planned for the Smart Creek target zones on the eastern side of the project. Three 600m-

800m diamond drill holes have been plotted. These holes should take approximately 45 days to

complete.

Sunrise Mine Target - Phase 2

The 2026 IP Geophysical Survey revealed a chargeable area of interest to the north of the Sunrise Mine

and also delineated a chargeability feature south of the Sunrise Mine. The southern anomaly continues

southward toward the Radio Tower target. 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 Four 600m-800m diamond drill holes have been plotted. These holes should take

approximately 60 days complete.

More in-depth program details will be reported upon commencement of the drill program.

About Domestic Metals Corp.

Domestic Metals Corp. 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.

A

- 4 -

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.

Domestic Metals Corp. is led by an experienced management team and an accomplished technical team,

with successful track records in mine discovery, mining development and financing.
