TORONTO, Sept. 8, 2022 - Silver Mountain Resources Inc. ("Silver Mountain", "AGMR" or the "Company") is pleased to announce initial results from underground channel sampling at the Reliquias silver mine in Huancavelica, central Peru. Assays have been received for 183 rock channel samples taken from Level 415 of the Meteysaca Vein (Fig.1). This well-mineralized ore shoot of the Meteysaca Vein is exposed over 285 m along the 415 m level. The results reported today were collected from Zones 1 to 4 over a strike length of 203 m, while sample assays taken over a strike length of 82 m in Zone 5 are still pending (Fig.1). The Meteysaca Vein extends further southeast, however, for sampling to continue along strike, the ongoing rehabilitation of the 415 m level needs to be completed.

Samples were taken using an electric percussion hammer to produce a channel perpendicular across the veins and mineralized structures. By cutting a continuous channel approximately 3-5 cm deep by 10 cm wide, the channel samples basically equal a drill core in their significance for future resource estimation. Where the structure is exposed along the back of the drift, channels were cut across the vein systematically every 4 m. Channel lengths range between 0.30 m and 2.90 m.

The underground sampling results from the Meteysaca Vein confirm the continuity of well-developed polymetallic mineralization within the structure, with significant concentrations of silver (Ag), lead (Pb), zinc (Zn), and copper (Cu). Gold grades were considerably higher than expected, ranging between 0.11 g/t and 4.15 g/t. To highlight the continuity of this vein system, the grades and widths of channels were averaged over each of the four zones shown in Fig. 1.

Alfredo Bazo, President and CEO, commented: "The underground sample results from the 415 level provide verification of the tenor and continuity of high-grade Ag-Pb-Zn-Cu mineralization in the Meteysaca Vein. We are thrilled with the encountered gold grades, which could positively impact the results of our future resource estimate. The systematic channel sampling program complements the ongoing underground drilling and should facilitate the conversion of additional historic resources into NI 43-101 compliant resources."

The Meteysaca structure exhibits brecciation, irregular banding and crustiform textures typical of intermediate sulphidation veins. Sulphide minerals are present as fine veinlets, semi-massive pods, or in disseminated form, within a matrix composed of at least three generations of quartz, with minor barite and calcites. Galena, sphalerite, silver sulpho-salts, chalcopyrite, and minor pyrite were encountered. The Meteysaca Vein shows average widths of approximately 0.50 m in the western part of the ore shoot. Associated with a change in strike direction observed in Zone 4 (Fig.1), the vein thickness increases towards the southeast, averaging 0.89 m in width.

The following table provides more detail regarding the channel sample results from the Meteysaca Vein structure.

Silver Mountain Resources Inc. is a silver explorer and mine developer planning to restart production at the Reliquias underground mine and undertake exploration activities at its prospective silver camps at the Castrovirreyna Project in Huancavelica, Peru.

For additional information in respect of the Castrovirreyna Project, please refer to the Company's technical report, titled National Instrument 43-101 Technical Report-Castrovirreyna Project, Peru, dated October 6, 2021, amended November 18, 2021, effective date August 17, 2021, available at https://sedar.com

Silver Mountain's subsidiary Sociedad Minera Reliquias S.A.C. owns 100% of its concessions and holds more than 27,000 hectares in the district of Castrovirreyna, Huancavelica, Peru.

Silver Mountain follows systematic and rigorous sampling and analytical protocols which meet industry standards. These protocols are summarized below.

All channel samples were collected with an electric percussion hammer and do not exceed 1.0 m 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 ALS laboratory in Lima for assaying. Silver Mountain independently inserts certified control standards (purchased from OREAS and Target Rocks), 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 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 multi-acid digestion with ICP-AES analysis for other elements. Samples with results that exceed maximum detection values for the main elements of interest (Ag, Zn, Pb, Cu, Au) are re-analyzed using precise ore-grade ICP analytical techniques, while high gold values are re-analyzed by fire assay with a gravimetric finish.
