Metalsource Mining Commences Geophysical Survey Program at North Carolina Projects

Executive Summary

• Metalsource Mining has commenced a Magnetotelluric (MT) geophysical survey across its Silver Hill Mine and Byrd‑Pilot project areas in North Carolina.
• Approximately 40 MT stations will be deployed over a ~20‑day field program, with results to be processed using 2‑D Zonge Smooth Model inversion and integrated into existing geological models.
• Subject to the MT results, the company plans a follow‑up detailed Induced Polarization (IP) survey to refine future drill targets.

Key Details

• Survey Contractor: Durango Geophysical Operations, LLC (DGO).
• Survey Scope: ~40 MT stations across both project areas; field acquisition expected to finish early December 2025.
• Technology Used: Phoenix Geophysics MT receivers and transmitters with Remote Reference noise reduction.
• Data Processing: 2‑D Zonge Smooth Model inversion (unconstrained) integrated into Leapfrog geological models.
• Field Oversight: John Reynolds, President of DGO; data interpretation by Karen R. Christopherson, Chinook Geoconsulting, Inc.
• Future Work: Potential follow‑up detailed IP survey pending MT results to further define drill targets.
• Project Highlights – Silver Hill: 1,128‑acre property with historic silver production; recent surface sample (SH25‑003) returned 444 g/t Ag, 17.7 g/t Au, 8.61 % Pb, 0.507 % Zn.
• Project Highlights – Byrd‑Pilot: Historic indication of porphyry gold‑copper system; broad surface gold anomalies and strong self‑potential signals; no recent drilling on Meridian discovery zone.
• Qualified Person: Information reviewed by Rory Kutluoglu, P.Geo., under NI 43‑101 standards.

Notable Quotes

“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.”
