Silver Hammer Mining Corp. (CSE: HAMR,OTC:HAMRF) (the "Company" or "Silver Hammer") is pleased to announce positive assay results from its Phase 1 drill program on the 100% owned Silverton Silver Mine Project ("Silverton") in Nye County, Nevada.
"After experiencing issues in the assay lab, and resampling the drill holes, the Phase 1 drill targets beneath the 100% owned historical Silverton mine have produced encouraging results. The targeted major faults and mineralized structures are now interpreted to continue below the shallow historic workings as mineralized shoots. Exploration vectors point downward along these newly identified zones, indicating the potential discovery of a chimney and manto CRD-type of silver mineralization at depth below the existing Silverton mine workings," commented Peter A. Ball, CEO of Silver Hammer Mining. "Grab samples at surface assayed up to 581 g/t Ag, and drillhole grades assayed up to 361 g/t Ag over 1.5m beneath existing workings. Work to date will assist our technical team to further explore for a potential large feeder zone beneath the Silverton mine."
Phase 1 drilling comprised six drill holes totalling 738 metres, drilled in the Central Zone of the Western Silver Zone, in vicinity of the Silverton Mine workings, and on the Eastern Gold Zone, characterized by parallel zones of jasperoid alteration (see Fig. 1).

Mineralization has been confirmed by fire assay (Au) and multielement ICP analysis. Zones of alteration - silicification in the western portion of Silverton host silver while the jasperoid mineralization in the Eastern Gold Zone is host to gold; mineralized intercepts are listed below in Table 1.

N.B.: Drill holes were fanned out from drill pads into conjugate sets of mineralized structures; true widths of mineralization vary between an estimated 50% and 90% of reported intervals.
Mineralized intercepts and the lithology encountered in the drill holes are shown on the two 3D views (see Fig. 2 and Fig. 3). It is notable that the mineralization encountered in the drilling extends below the reported depths of the historic Silverton mine workings.

Mr. Ball added, "In addition to the positive silver results in the Central Zone, we are pleased to have received confirmation of gold mineralization in the Eastern Gold Zone with two parallel zones of jasperoid alteration having assayed grades of up to 0.65 ppm Au over five feet (within the 10-foot 0.554ppm Au intercept)."

Preceding the Phase 1 drill campaign, mapping and rock sampling was conducted in the vicinity of the historic Silverton Mine workings and in the Eastern Gold Zone jasperoid alteration areas. Five surface rock samples were collected; the sample locations are shown on the maps below (see Fig. 4).

The sample grades for surface rock samples received from ALS Laboratories ("ALS") are:
| Sample ID | Ag (ppm) | Au (ppm) | Sb (ppm) |
| 1071610 | 61.7 | 0.066 | 16.45 |
| 1071611 | 581 | 0.102 | 68 |
| 1071612 | 98.3 | 0.029 | 65 |
| 1071613 | 70.7 | 0.013 | 16.65 |
| 1071614 | 2.03 | 0.147 | 58.7 |
The above-listed surface grab samples were collected from silicified structures exposed on surface. Investors are cautioned that grab samples are inherently selective and serve to prove the presence of mineralization only. Grab sample were put into sample bags, marked and sealed on-site at the sample location. The samples were then transported in secured bags directly from the sample location sites to ALS Laboratories, Reno, Nevada; analysis was performed at ALS Reno and ALS North Vancouver. Both are ISO/IEC 17025 accredited labs. Analysis for gold was completed by Fire Assay; silver and a suite of multielements were performed by ICP. Certified standards and blanks were inserted at a rate of two standards and a blank per 10 samples; duplicates were also completed.
These rock samples compare well with the surface sampling campaigns undertaken in 2022 and 2023. The RC chip samples were treated with identical custody, security and assaying protocols. Initial gold assay was performed on the rocks and RC chips at ALS Reno, however failures of Certified Reference Materials (CRM, standards) led to re-assaying for gold at ALS North Vancouver, where all the QAQC samples (independent CRMs and blanks) assayed within acceptance limits.
