Silver Hammer to begin phase 1 drilling at Silverton

Executive Summary

• Silver Hammer Mining Corp. has engaged Alford Drilling LLC to commence Phase 1 of a drill program at its 100%-owned Silverton project in Nevada, with operations scheduled to begin by the second week of November 2025.
• The Phase 1 program involves up to 5,000 feet of drilling across up to eight reverse circulation (RC) holes, specifically designed to test for downdip continuity of high-grade silver mineralization below historical underground workings.
• The company is simultaneously advancing exploration plans for the Fahey Group project in Idaho and finalizing permitting for the Eliza project, while highlighting historical high-grade silver production and recent in-situ sampling results at Silverton.

Key Details

• Drilling Contractor: Alford Drilling LLC (Elko, Nev.) engaged for drilling; Modern Land and Development LLC engaged for site preparation (road work, drill pad, and sump construction).
• Drill Program Scope: Up to 5,000 feet in up to eight reverse circulation (RC) holes.
• Start Date: Planned to commence by the second week of November 2025.
• Primary Objective: Test below the high-grade Silverton underground workings to verify downdip continuity of mineralization previously mined in the 1930s and 1950s.
• Historical Production: Silverton mine produced less than 100,000 tons between the 1930s and 1953, with historical grades ranging from 300 g/t Ag to 933 g/t Ag.
• Previous Exploration Data:
  • Eastern System (Gold-dominant): Hosted in volcanic rock; grades ranging from 0.06 g/t Au to 6.1 g/t Au.
  • Western System (Silver-dominant): Hosted in silicified limestone; grades ranging from 0.32 g/t Ag to 692 g/t Ag.
• Recent In-Situ Sampling: Chip and channel samples from the central zone (past mining/pitting/trenching area, approx. 1,000 ft diameter) returned silver grades up to 692 g/t Ag, with six samples exceeding 100 g/t Ag.
• Geological Setting: Located within the Williams Ridge caldera (over 30 miles in diameter); prospective for CRD-type mineralization in Devonian carbonates and epithermal-type in Tertiary tuffs.
• Alteration Targets:
  • Primary Target: Western central zone near intersection of north-south Silverton and east-west basin faults; characterized by silicification, veins, stockwork, and jasperoid.
  • Secondary Target: Eastern portion; characterized by quartz veinlets and extensive jasperoid alteration with gold mineralization.
• Other Project Updates:
  • Fahey Group (Idaho): Initial exploration plan being put together.
  • Eliza Project (Nevada): Plan of operations permitting being finalized; area contains multiple historical high-grade silver mines.
• Qualified Person: Damir Cukor, PGeo, Technical Director, reviewed and approved scientific and technical aspects under NI 43-101.

Notable Quotes

• "The company will finally test below the high-grade Silverton underground workings... It is always an exciting point when you have the opportunity to test below a previously operating high-grade silver mine that closed nearly 80 years ago!" — Peter A. Ball, President and CEO.
• "The company is also currently putting together an initial exploration plan to review the Fahey Group silver project that was recently acquired in Idaho and in addition also finalizing the plan of operations permitting for the Eliza project... It will be a busy year ahead for Silver Hammer, and we appreciate our shareholders patience and support." — Peter A. Ball, President and CEO.
