Silver Mountain Successfully Completes Geotechnical Studies And Provides Update On Activities At Its Reliquias Mine

Since early 2023, the Company has established a two-pronged strategy to advance the mine rehabilitation and engineering needed towards restarting operations at the Reliquias mine, based on the current mineral resource estimate published on April 12^th, 2023 (https://agmr.ca/silver-mountain-delivers-initial-ni-43-101-compliant-mineral-resource-estimate-for-reliquias-mine/) and to incorporate new areas drill tested during Phase 2 of the 2023 drill program. As part of this strategy, the Company has received the geotechnical evaluation by DCR Ingenieros of Lima, Peru. This report will be used to determine a suitable mining method and design a mine plan for developing the Reliquias underground mine.

Alvaro Espinoza, CEO of Silver Mountain, stated, "The completion of the geotechnical study is yet another major milestone hit by our onsite technical team at Reliquias. We are very pleased with the work done by DCR Ingenieros, within budget and on time. The geotechnical evaluation is a key component toward restarting operations at Reliquias, and our team is working flat out to deliver a mine plan and a streamlined mine schedule that maximize value for our shareholders."

Richard Contreras, Silver Mountain´s COO, commented, "The results of this geotechnical study confirm that the wallrock at Reliquias is competent throughout the deposit. We expect limited ground support needed throughout the mine, without the need to incorporate heavy support methods such as shotcrete or steel arches, thus maintaining a low Opex and sustaining capital costs. Our experienced engineering team has worked in multiple underground mines in Peru, and minimizing the need to use expensive ground reinforcement tools should significantly improve the Project´s economics."

The Company´s field crews have continued to rehabilitate the historic mine working at Reliquias. So far 14.8 kilometres of tmine rehabilitation has been completed, well within budget. Phase 2 of the 2023 drill program, consisting of 12,500 metres of underground diamond drilling, was completed in October 2023 and the three rigs have now been demobilized, with results from the final drill holes expected by early November. Once they are received, the database will be sent to our resource consultants to prepare a mineral resource estimate update, incorporating the significant step out results from this program.

Earlier in 2023, the Company commissioned DCR Ingenieros S.A. ("DCR"), an experienced Lima-based engineering firm, to prepare a geotechnical evaluation of the Reliquias mine, using drill core geotechnical logging from over 7,000 metres of diamond drilling and 38 underground stations located throughout the mine. The Company has now received the report, where DCR concludes that most of the wallrock at Reliquias can be classified as Good, defined as having a Rock Mass Rating (RMR) of between 61 and 80, thus requiring limited ground support. The existence of several kilometers of underground tunnels, some dating over 50 years, supports this conclusion. DCR also concludes that several mining methods could be applicable at Reliquias, and the Company's technical team is working towards a mine plan using sublevel stoping and bench and fill methods with stopes no higher than 10 metres to minimize dilution.

The Company has also started a detailed metallurgical work program for Reliquias, sending 7 representative samples from several of the Reliquias veins to Plenge Laboratory in Lima for open circuit and locked cycle testing. Results are expected during Q4 2023 and will be announced as soon as they are received and will be incorporated into the upcoming mineral resource estimate update and future Preliminary Economic Assessment planned for 2024. These milestones are part of the Company´s strategy to advance Reliquias towards production as fast as possible, taking advantage of the existing infrastructure, its long running relationship with local communities and its experienced technical team which has managed several successful underground operations in Peru.

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

Rock 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 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.
