NEWS RELEASE

Metalsource Mining Commences Geophysical Survey Program at North Carolina

Projects

Vancouver, BC – November 20, 2025 – Metalsource Mining, Inc. (“Metalsource” or the

“Company”) is pleased to announce the commencement of a geophysical survey program at its

Silver Hill Mine and Byrd-Pilot project areas in Davidson and Randolph Counties, North

Carolina.

The Company has engaged Durango Geophysical Operations, LLC (DGO), a specialized

electrical geophysics contractor, to conduct reconnaissance Magnetotelluric (MT) with intent to

conduct followup detailed Induced Polarization (IP) surveys across both project areas.

Program Highlights:

• Survey Scope: Approximately 40 MT stations planned across the Silver Hill Mine and Byrd-

Pilot project areas

• Program Duration: ~20-day field acquisition program with completion in early December,

2025

• Technology: State-of-the-art Phoenix Geophysics MT receivers and transmitters utilizing

Remote Reference noise reduction techniques for high-quality data collection

• Data Integration: Survey results will be processed using 2-D Zonge Smooth Model Inversion

(unconstrained) and integrated into the Company’s existing Leapfrog geological models

The reconnaissance MT survey is designed to identify subsurface geological structures and

potential mineralization zones. Field operations are being overseen by John Reynolds,

President of DGO, with data interpretation to be conducted by Karen R. Christopherson of

Chinook Geoconsulting, Inc.

Subject to results from the initial MT survey, the Company anticipates conducting a follow-up

detailed IP survey program to further refine drill targets.

“This geophysical program represents the next step in our systematic exploration approach in

this historic mining district,” said Joe Cullen, Chief Executive Officer of Metalsource Mining. “The

MT survey data will help us better understand the subsurface geology and alteration to identify

priority targets.”

Silver Hill Project

Located in the Carolina Terrane, the property is underlain by volcaniclastic and volcano-

sedimentary rocks predominantly of Neoproterozoic and Cambrian age. This terrane has been

suggested to be an extension of the Avalon Terrane. The property is 1,128 acres located in

Davidson County, North Carolina. As the first significant discovery and first silver-producing

mine in America, there is an extensive drillhole database, underground mapping, historic dumps

and underground chip samples which comprise the historic dataset. This mineralization is

currently known to extend to 550m from surface, in a steeply trending series of lenses, which

remain open in multiple directions.Bolstering these historic records, recent surface sampling

contained results including SH25-003 containing 444g/t Ag, 17.7 g/t Au, 8.61% Pb and 0.507%

Zn.

Byrd-Pilot Mountain Project

Located in central North Carolina, within the Carolina Terrane. Early USGS work in the 1980s

flagged the area as possibly hosting a porphyry gold-copper system, subsequent work

demonstrated broad gold mineralization in soils, trenches, and shallow RC drilling, coincident

with strong self-potential anomalies. Geology shows intense quartz-sericite-pyrite alteration,

high-sulfidation signatures, and high-alumina minerals (like Haile and Brewer deposits to the

south), suggesting potential for a large epithermal or porphyry-related gold system. Geologic

modelling indicates east-west trend to the identified mineralization, open in multiple directions,

with oxidation noted down to a depth of 30m. No drilling has tested the Meridian discovery zone

since those 1980s campaigns, leaving potential for significant resource expansion through work

commitments of the agreement.
