Metalsource begins drilling at Silver Hill, Byrd-Pilot

Executive Summary

• Metalsource Mining Inc. has commenced a 1,600-meter diamond drilling program across its Silver Hill and Byrd-Pilot projects in North Carolina.
• The program employs a dual-target strategy: validating historic mineralization at Byrd-Pilot and testing for updip and downdip extensions at Silver Hill.
• A parallel magnetotelluric (MT) geophysical survey is being conducted to support drill targeting, with operations expected to continue through the first quarter of 2026.

Key Details

• Drilling Scope: 1,600 meters of diamond drilling across two distinct geological targets.
• Byrd-Pilot Project Focus:
  • Twinning and validating historic drill intercepts using modern techniques and QA/QC protocols.
  • Targeting potential for a large epithermal or porphyry-related gold system based on historic USGS work and soil/trench sampling showing broad gold mineralization.
  • Geologic modeling indicates an east-west trend to mineralization, open in multiple directions, with oxidation noted down to 30 m.
• Silver Hill Project Focus:
  • Testing bedrock anomalies and the projection of known mineralization.
  • Primary goal: Identify the upper projection of mineralization between historic underground workings and recent surface sampling (updip extension of approx. 120 m).
  • Secondary goal: Test downdip extensions and southern expansion of known mineralization.
  • Historic context: First significant silver discovery and first silver-producing mine in America; mineralization known to extend to 550 m from surface.
  • Recent surface sampling highlight: SH25-003 returned 444 g/t Ag, 17.7 g/t Au, 8.61% Pb, and 0.507% Zn.
• Geophysics: Magnetotelluric survey conducted by Durango Geophysics to provide subsurface characterization.
• Contractor & Timeline: Boart Longyear engaged as drilling contractor; operations expected to continue through Q1 2026.
• Data Handling: Drill core logged on-site and sampled for assay; results to be released as available.
• Qualified Person: Rory Kutluoglu, PGeo, reviewed and prepared the scientific and technical information under NI 43-101.

Notable Quotes

• "We're excited to begin this well-planned drill campaign... The program is strategically designed to advance both properties simultaneously -- validating historic results at Byrd-Pilot while aggressively testing high-priority expansion targets at Silver Hill. The integration of our MT survey data will provide valuable subsurface information to guide our ongoing exploration efforts." — Joe Cullen, CEO
