December 8, 2025 – Vancouver, BC – Silver Hammer Mining Corp. (CSE:HAMR) (the
“Company” or “Silver Hammer”) is pleased to announce that the Company has commenced drilling at
its 100%-controlled Silverton Project in Nye County, Nevada. The Phase 1 exploration drill program
will be comprised of approximately 5,000 feet of reverse circulation (“RC”) holes. The Company also
completed a project-wide mapping and sampling exercise at Silverton in November 2025 with assays
pending, which will assist in the current drill program.
“The drill rig arrived on site on December 3, 2025. 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. The Phase 1 drill program will be focused initially on testing our priority targets that
we have outlined in the attached figure,” commented Peter A. Ball, President & CEO. “The Company
is actively reviewing its other projects for 2026. Our team recently spent time on the ground at the
California Mine Patent claim. The California Patent is located entirely within the Eliza Silver Project
claim block and is close to having its Plan of Operations permit finalized for 2026 drilling. With the
price of silver exceeding $58 per ounce, we look forward to a busy winter ahead and appreciate our
shareholders patience and support.”
Silverton Project, Nevada
Silver Hammer has identified several targets at its Silverton Project and currently has multiple drill
targets identified. The Company’s technical team has ranked and prioritized the key targets at Silverton
designed to initially test the mineralized area proximal to, and under, the historic high-grade, near surface
mine workings with up to eight (8) RC drill holes, totalling up to 5,000 feet. The drill program is designed
to test primarily for down-dip continuity of the high-grade silver mineralization previously mined in the
1930s and 1950s.
Previous Company exploration work, including rock and soil sampling, geologic mapping and satellite
imagery, provided evidence for two separate mineralized systems: an eastern, gold-dominant system and
a western,silver-dominantsystem. Prior exploration on the volcanic-hosted, gold system returned grades
ranging from 0.06 grams per tonne (“g/t”) to 6.1 g/t gold (“Au”). The silver dominated mineral system
is hosted by silicified limestone with grades ranging from 0.32 g/t silver (“Ag”) to 692 g/t Ag, from
Company exploration work (please refer to the Company’s press release dated November 29, 2021 for
previous disclosure).
Silver was discovered at the Silverton Mine in 1921. Small-scale production is recorded from the 1930s
and the mine produced its lastshipment in 1953, totalling less than 100,000 tons, with historic production
gradesranging from 300 g/t Ag to 933 g/t Ag (Source: westernmininghistory.com and thediggings.com).
In addition to the identified 100-foot shaft and underground workings (five known adits), the area to the
west and the north of the mine shaft has been the subject of only surface exploration comprised of see & read more on
