Silver Hammer Commences Drilling at Its 100% Owned Silverton Project in Nevada

Executive Summary

• Silver Hammer Mining Corp. has commenced Phase 1 drilling at its 100%‑controlled Silverton Project in Nye County, Nevada, with up to 5,000 ft of RC holes planned.
• The drill program will test down‑dip continuity of historic high‑grade silver mineralization (up to 933 g/t Ag) beneath former underground workings and prioritize eight target zones.
• A recent project‑wide mapping and sampling effort was completed in November 2025, with assay results pending and expected to guide the current drill campaign.

Key Details

• Drill rig arrived on site on December 3, 2025; drilling began immediately thereafter.
• Phase 1 consists of ≈5,000 ft (≈1,524 m) of reverse‑circulation drilling across up to 8 RC holes targeting the historic high‑grade zone and adjacent targets.
• Historical underground workings previously produced grades as high as 933 g/t Ag; current program aims to test continuity beneath these zones.
• Prior exploration identified two mineralized systems:
• Eastern gold‑dominant system: historic assays 0.06–6.1 g/t Au.
• Western silver‑dominant system: historic assays 0.32–692 g/t Ag, with six samples > 100 g/t Ag in the Central Zone (≈1,000 ft diameter).
• Mapping and surface sampling completed November 2025; assay results are pending and will be incorporated into drill target refinement.
• The company is also reviewing other projects for 2026, notably the California Mine Patent claim within the Eliza Silver Project, with a Plan of Operations permit expected to be finalized for 2026 drilling.
• President & CEO Peter A. Ball highlighted the current silver price (> $58/oz) as supportive of an active winter drilling program.

Notable Quotes

“We have now commenced drilling to test below the high‑grade Silverton underground workings, which previously operated close to 80 years ago at grades up to 933 g/t Ag… With the price of silver exceeding $58 per ounce, we look forward to a busy winter ahead and appreciate our shareholders’ patience and support.” – Peter A. Ball, President & CEO
