SILVER MOUNTAIN REPORTS HIGH-GRADE SILVER RESULTS FROM SURFACE CHANNEL SAMPLING PROGRAM NEAR THE RELIQUIAS MINE, PERU

Silver Mountain Resources Inc. has received assay results from surface channel sampling completed as part of its brownfield exploration program surrounding its 100-per-cent-owned Reliquias mine, located in central Peru.

The company's exploration team is currently evaluating areas surrounding the proposed Reliquias production centre. In parallel with detailed geological field mapping, systematic and representative channel samples are being collected from surface outcrops, a standard methodology used during the evaluation of vein-type structures. All samples are collected perpendicular to the vein structures using percussion tools and manual cutting equipment.

Channel sampling results

Silver Mountain geologists continue to collect channel samples as part of the brownfield exploration program surrounding the Reliquias mine. Table 1 below summarizes the channel sample distribution along the vein and presents the compiled weighted assay results.

The values in Table 1 above are for illustrative purposes only and do not imply economic viability. See below under the heading "Caution regarding channel sampling."

Channel sampling along a 550-metre segment of the central portion of the Seguridad SE vein, located approximately 2.1 kilometres north of the Reliquias mine, returned a weighted average grade of 2,003 grams per tonne silver over an average true vein width of 0.45 metre. These results indicate that high-grade silver mineralization may remain open along strike, both at the Seguridad SE vein and in other nearby veins belonging to the same structural system.

The Seguridad SE vein may represent the southern extension of the historical Seguridad mine. If confirmed through further exploration, the structure could exceed 2.7 kilometres in total strike length, open toward the southeast, and would run parallel to the Sacasipuedes and Caudalosa vein systems, which are the main mineralized structures hosting the majority of the Reliquias mine's silver resources.

Alvaro Espinoza, chief executive officer of Silver Mountain, commented: "These results further validate our focus on near-mine brownfield exploration as a disciplined and cost-effective strategy. Identifying high-grade silver mineralization at surface, close to existing infrastructure, strengthens the overall value proposition of the Reliquias district and supports our longer-term objective of expanding the resource base as we advance toward a planned production restart."

Sampling, quality assurance/quality control and analytical procedures

Silver Mountain follows systematic and rigorous sampling and analytical protocols in accordance with industry best practices. These protocols are summarized below.

Rock channel samples were collected with an electric percussion hammer and do not exceed 1.0 metre in length. Channels are broken at obvious geologic boundaries to correctly separate rock types and mineralization styles. The sample bags were sealed with a plastic zip tie and identified with a unique sample number, pending shipment to a certified laboratory sample preparation facility.

Samples are sent by batch to the Bureau Veritas and Certimin laboratories in Lima, Peru, for assaying. Silver Mountain independently inserts certified control standards, fine and coarse blanks, and duplicates into the sample stream to monitor data quality. These standards are inserted blindly to the laboratory in the sample sequence prior to departure from the core storage facilities. At the laboratory, samples are dried, crushed and pulverized and then analyzed using a fire assay (AA finish) analysis for gold and a full multiacid digestion with ICP-AES analysis for other elements. Samples with results that exceed maximum detection values for the main elements of interest (silver, zinc, lead and copper) are reanalyzed using precise ore-grade ICP analytical techniques while high gold values are reanalyzed by fire assay with a gravimetric finish.

Caution regarding channel sampling

The channel sampling results described in this news release are preliminary in nature and are not necessarily indicative of mineralization that may be encountered in the subsurface. Channel samples are collected from surface outcrops and may not be representative of subsurface conditions. Additional drilling and sampling will be required to determine whether mineralization extends at depth and to estimate mineral resources in accordance with NI 43-101. There is no certainty that further exploration will result in the discovery of mineral resources.

We seek Safe Harbor.
