TORONTO, Sept. 21, 2022 - Silver Mountain Resources Inc. (TSXV: AGMR) (OTCQB: AGMRF) (BVL: AGMR) ("Silver Mountain", "AGMR" or the "Company") is pleased to provide an update on its underground drilling at the Reliquias silver mine at the Company's Castrovirreyna Project in Huancavelica, central Peru. 58 bore holes have been completed to date, with results of 5 holes drilled to test the Matacaballo and Sacasipuedes veins included in this release (Table 1). The main objective of the fully funded drill program is to establish a National Instrument 43-101 - Standard of Disclosure for Mineral Projects ("NI 43-101") compliant mineral resource in H1 2023 that will form the basis of our production decision in H2 2023. In addition, the Company aims to better characterize and extend the known silver-rich zones at depth.¹

Alfredo Bazo, President and CEO, commented: "The drill hole results confirm the continuity of high-grade Ag-Pb-Zn-Cu mineralization in both the Matacaballo and Sacasipuedes vein, close to existing mine workings at the Reliquias deposit. We are delighted that various bore holes have intersected more than one mineralized interval, which appear to represent additional structures such as the Ayayay vein previously observed in historic mine workings (see Fig.1). Our geological team is currently evaluating these intercepts to incorporate them in our 3D geological model."

The following table shows the detailed results of mineralized intercepts encountered in drill holes SMR-15-22-MTC to SMR-19-22-SCS.

The Company also announces the appointment of Independent Trading Group ("ITG") to provide market making services in accordance with the policies of the TSX Venture Exchange (the "TSXV"). Under the market making services agreement dated February 2, 2022 (the "Agreement"), ITG will trade securities of the Company on the TSXV with the objective of maintaining a reasonable market and improving the liquidity of the Company's class A common shares.

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.

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 drill holes are diamond core holes with HQ or NQ core diameters. Drill core is collected at the underground drill site where recovery measurements are taken before the core is transported by truck to the core logging facility at the Caudalosa Grande mine camp, where it is photographed and geologically logged. The core is then cut in half with a diamond saw blade with half the sample retained in the core box for future reference and the other half placed into a pre-labelled plastic bag, sealed with a plastic zip tie, and identified with a unique sample number. The core is typically sampled over a 1-2 metre sample interval unless the geologist determines the presence of an important geological contact. The bagged samples are then stored in a secure area pending shipment to a certified laboratory sample preparation facility. Samples are sent by batch to the ALS laboratory in Lima for assay. 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 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) are re-analyzed using precise ore-grade ICP analytical techniques, while high gold values are re-analyzed by fire assay with a gravimetric finish.
