Silver Hammer begins drilling at Silverton

Executive Summary

• Silver Hammer Mining Corp. has commenced Phase 1 drilling at its 100%-owned Silverton project in Nye County, Nevada, following the arrival of the drill rig on December 3, 2025.
• The initial program involves approximately 5,000 feet of reverse circulation (RC) drilling across up to eight holes, targeting the downdip continuity of historic high-grade silver mineralization beneath the former underground workings.
• The company is also advancing permitting for its California mine patent claim (part of the Eliza project) for 2026 drilling, citing strong silver prices exceeding $58/oz.

Key Details

• Drilling Program Scope: Phase 1 consists of approximately 5,000 feet of reverse circulation (RC) holes.
• Drilling Start Date: The drill rig arrived on site on December 3, 2025.
• Primary Target: Testing below the high-grade Silverton underground workings, which operated ~80 years ago with grades up to 933 g/t Ag. The goal is to test for downdip continuity of this mineralization.
• Secondary Targets: The program will also test priority targets identified through recent project-wide mapping and sampling (completed November 2025, assays pending).
• Historic Production Context: The Silverton mine produced fewer than 100,000 tons between the 1930s and 1953, with historic grades ranging from 300 g/t Ag to 933 g/t Ag.
• Geological Setting: Located within the Williams Ridge caldera (30+ miles in diameter). The area features ring, radial, and low-angle faults acting as conduits for hydrothermal solutions.
• Mineralization Systems:
  • Western/Silver-Dominant System: Hosted by silicified limestone. Previous exploration returned grades from 0.32 g/t to 692 g/t Ag. The "Central Zone" (approx. 1,000 ft diameter) shows pervasive weak silicification, stockwork veins, and jasperoid near the intersection of the Silverton and Basin faults. In situ samples returned up to 692 g/t Ag, with six samples over 100 g/t Ag.
  • Eastern/Gold-Dominant System: Hosted by volcanic tuffs. Previous exploration returned grades from 0.06 g/t to 6.1 g/t Au. This area features quartz veinlets and extensive jasperoid alteration.
• Other Project Updates: The company is finalizing the plan of operations permit for the California mine patent claim (within the Eliza silver project claim block) for 2026 drilling.
• Market Context: CEO Peter Ball noted silver prices have exceeded $58 per ounce.
