Silver Hammer Advances to Phase One Drill Program at Its 100% Owned Silverton Project in Nevada

Vancouver, British Columbia--(Newsfile Corp. - October 29, 2025) - Silver Hammer Mining Corp. (CSE: HAMR) (the "Company" or "Silver Hammer") is pleased to announce that the Company has engaged Alford Drilling, LLC of Elko, Nevada to complete the Phase 1 Drill Program for its 100%-controlled Silverton Project in Nye County, Nevada. In addition, the Company has also engaged Modern Land and Development, LCC for site preparation including road work, and drill pad and sump construction. The exploration drill program will be comprised of up to 5,000 feet in up to eight (8) reverse circulation ("RC") holes. The drill program is now planned to commence by the second week of November 2025.

"The Company will finally test below the high-grade Silverton underground workings," commented Peter A. Ball, President & CEO. "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! 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, where multiple historical high-grade silver mines have been awaiting modern day exploration and drilling for over 80 years. It will be a busy year ahead for Silver Hammer and we 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-dominant system. 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 last shipment in 1953, totalling less than 100,000 tons, with historic production grades ranging 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 numerous small test pits and trenches. In-situ rock samples by the Company (chip and channel) returned silver grades, up to 692 g/t Ag, with a further six samples having returned over 100 g/t Ag, from this Central Zone from past mining, pitting and trenching; the Central Zone measures approximately 1,000 feet in diameter (refer to Figure 1).

The Silverton Mine Silver Project is situated within the Williams Ridge Caldera, near its eastern rim. The caldera is a large-scale structure, over 30 miles in diameter, with ring faults, radial faults and low-angle faults providing ample conduits for hydrothermal solutions following the Tertiary eruption of rhyolitic magmas, forming ash-flow tuffs within the caldera structure. The lithologic unit overlying the caldera magma chamber was thick Devonian sedimentary units, predominantly dolomite, with intercalated arenite, a setting which may be prospective for CRD-type mineral occurrence in the carbonates and epithermal-type in the tuff units.

Alteration noted in area has been mapped as pervasive weak silicification in the Devonian-aged carbonate units and weak argillic in the Tertiary-aged tuffs. Alteration intensifies in two areas of the property, in the vicinity of mapped faults and shears:

• In the western portion of the property, in the Central Zone, in proximity of the intersection of the N-S Silverton and the E-W Basin Faults, silicification comprises veins, zones of stockwork and occurrences of jasperoid with significant silver mineralization — the primary drill target.
• In the eastern portion of the property an area of quartz veinlets and extensive jasperoid alteration with gold mineralization forms a secondary exploration target.
