METALSOURCE MINING COMMENCES GEOPHYSICAL SURVEY PROGRAM AT NORTH CAROLINA PROJECTS

Metalsource Mining Inc. has commenced 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 follow-up 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: approximately 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 drill hole database, underground mapping, historic dumps and underground chip samples which comprise the historic data set. This mineralization is currently known to extend to 550 metres 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 444 grams per tonne Ag (silver), 17.7 g/t Au (gold), 8.61 per cent Pb (lead) and 0.507 per cent Zn (zinc).

Byrd-Pilot Mountain project

Located in central North Carolina, within the Carolina terrane. Early USGS (United States Geological Survey) 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 (reverse circulation) drilling, coincident with strong self-potential anomalies. Geology shows intense quartz-sericite-pyrite alteration, high-sulphidation 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 30 metres. No drilling has tested the Meridian discovery zone since those 1980s campaigns, leaving potential for significant resource expansion through work commitments of the agreement.
