Sierra Madre Gold and Silver Ltd. Provides an Operational Update on Activities at the La Guitarra Silver-Gold Mine Complex in Estado De Mexico, Mexico Sierra Madre Gold and Silver Ltd. provided an operational update on activities at the La Guitarra silver-gold mine complex in Estado de Mexico, Mexico. Test mining and processing has been ongoing since June 25th, 2024. Beginning in October, the company began testing the operation of all three ball mills simultaneously and in various combinations. Daily throughput in the grinding and flotation circuits has been as high as 504 wet metric tonnes per day (WMT/d). From October 1st to October 18th, throughput has averaged 428 WMT/d. This average includes scheduled downtime to reline one mill and normal rainy season power outages. The company expects commercial production to begin before the end of the year. The flotation plant has been in continuous operation since the beginning of testing. Silver recoveries to date have averaged 78%. Based on recommendations from the Company's metallurgical consultants, a new reagent combination will be tested to enhance silver recovery of oxidized material. Gold recoveries have steadily increased from 74% in June to the current October average of 87%. Since the commencement of test operations, a total of 39,272 tonnes of economically interesting mineralized material has been put through the processing circuit. A total of 690.44 dry metric tonnes of concentrate has been shipped to MRI Trading. Average provisional concentrate payment grades have been 2,903 g/t sliver and 34.74 g/t gold. Test mining continues to provide sufficient tonnages to sustain the milling operations. A new development plan has been put into place to accelerate the mining of insitu mineralized material, reducing the reliance on oxidized retaques, which are backfill from 1990's stopes.

Sierra Madre Gold and Silver Ltd. Announces Commencement of Test Mining and Processing at the Guitarra Mine Complex in Estado De Mexico, Mexico Sierra Madre Gold and Silver Ltd. announced the commencement of test mining and processing at the Guitarra Mine Complex in Estado de Mexico, Mexico. The flotation plant has processed 5,698 dry tonnes (5,943 wet tonnes) of mineralized material from the Guitarra mine and is currently averaging 259 dry tonnes per day (tpd). This marks a significant milestone for the Company in the path to returning Guitarra to full commercial production of 500 tpd, which is now projected to commence in fourth quarter of 2024. Opening day ceremonies were recently attended by the Presidents of the Municipio of Temascaltepec de Gonzales and San Simon de Gurrero, representatives of the Estado de Mexico government, elected leaders of the local communities and the Company's Board of Directors. The Company currently has four operating Scoop trams, one low-profile haul truck and a Jumbo drill which were rebuilt by the Maintenance Department. In addition, the Company has purchased an 18- tonne dump truck for surface and underground haulage and a Stopemate long-hole drilling machine. The current test mining is using long hole and shrinkage mining techniques, with cut-and-fill operations planned to begin shortly. The current mine equipment availability is running at 88%, a clear indication of the quality and progress of the work that went into rebuilding the mining fleet. The flotation plant has three ball mills: a 5' x 8' mill, with a capacity of 84 tonnes per day (tpd); an 8' x '6 mill, with a capacity of 204 tpd; a 7' x 10' mill, with a capacity of 228 tpd. The 5' x 8' and 8' x 6' ball mills operate and run at 94% of nameplate capacity. The 7' x 10' mill will be phased into operation as test mining progresses toward the planned 500 tpd throughput. The mine currently employs 188 people, most from the local community. Many recently hired workers had previously worked at the mine and their return to Guitarra gives the company an experienced workforce with an in-depth knowledge of the mine. Tillkännagivande • Apr 21

Sierra Madre Gold and Silver Ltd. Provides an In-Depth Update of Its Activities At the 100% Owned Past-Producing La Guitarra Silver-Gold Mine Complex in Estado De Mexico, Mexico, 130 Km Southwest of Mexico City Sierra Madre Gold and Silver Ltd. provided an in-depth update of its activities at the 100% owned past-producing La Guitarra Silver-Gold Mine Complex in Estado de Mexico, Mexico, 130 km southwest of Mexico City. Mine Restart Study: The Company has retained TechSer Mining Consultants Ltd., of Vancouver, B.C., to complete the Mine Restart Study ("MRS"). This work will include an estimation of underground mine material for the Guitarra, Coloso and Nazareno mines and the Los Angeles bulk tonnage deposit. Additional evaluations will include an operating cost estimate covering the mine and recovery plant, based on reagent and consumable usage, energy, and diesel consumption, from the 2013 to 2018 operating period which will be updated for current pricing. Labour, staff and management costs will be based on the current wage structure and union labour contracts that have recently been signed. As part of the study, a capital cost estimate will be prepared to cover restart needs and will evaluate a potential throughput expansion within 24 months of commercial production. This data is to be supported by contractor bids and vendor prices. The above data will then be used in an economic evaluation to determine project viability. The MRS is expected to be completed in Second Quarter of this year. Mine and Infrastructure: Work has been ongoing to determine necessary steps for the potential re-start of production. In accordance with recommendations made by officials with the Secretaria de la Defensa Nacional, SEDENA, improvements to the underground powder magazines have been completed. On January 29, 2024, SEDENA approved Guitarra's 2024 explosives permit. This explosives permit must be renewed every year and was a milestone event for any potential resumption of operation. All other operating permits are current and in good standing. Compressed 6-inch air lines have been installed from the stationary compressors near the main San Rafael portal to the La Cruz portal, a distance of over one kilometre with a 240 metre gain in elevation. Compressors and electrical substations have been serviced and are operational. Minimizing initial development costs is one of the key factors being used to develop the near-term plan for advancement of the Project. As areas are identified and scheduled in the development plan, the existing haulage ways, access drives and ramps are being inspected for safety and rock stability, cleaned and readied. Processing Plant: All circuits in the processing plant are undergoing maintenance and rehabilitation work which would be required for the resumption of operations. In the grinding circuit, the three ball mills are being relined, all parts of the central drive shaft mechanisms overhauled, and the motors cleaned and tested. A fourth ball mill with limited capacity will not be rebuilt at this time. Overall, the crushing circuit was found to be in good shape with no costly equipment replacementor major repair items identified. Normal maintenance and overhaul work is ongoing. The fine ore storage bin has had the interior dividers and portions of the walls replated with heavy steel. Conveyor belts and associated motors have been serviced and wear and tear items have been replaced where needed. The flotation circuit is in good shape. Some piping is being replaced and the pumps are being overhauled and serviced. The Wemco flotation cells are in very good shape, needing only some replating work, along with normal maintenance. No repair work requiring a significant outlay of capital has been identified. The Denver cell circuit will not be needed at this time. The company's plant operations and maintenance team have advanced the preparation work for a potential plant restart within budget expectations. The MRS will study an initial production level of 350 tonnes per day. Additional evaluation will be completed on potentially increasing the grinding circuit's capacity to greater than 500 tonnes per day. As part of the MRS, an assessment was made of the throughput capacity of each circuit in order to determine where bottlenecks might exist in potentially expanding processing throughput using the current plant equipment.

Sierra Madre Gold and Silver Ltd. Announces Its First Project-Wide Resource Estimate for the La Guitarra Silver-Gold Mine and the Temascaltepec Mining District in Estado De Mexico, Mexico Sierra Madre Gold and Silver Ltd. announced its first project-wide Resource Estimate for the La Guitarra silver-gold mine and the Temascaltepec mining district in Estado de Mexico, Mexico. TechSer Mining Consultants Ltd. of Vancouver B.C. prepared the Mineral Resource Estimate, David Thomas, P.Geo. and QP Geology and Cristian Garcia, P.Eng. and QP Mining. The following tabulates the La Guitarra estimated Mineral Resources. Sierra Madre Increases M&I Silver-Equivalent Resources at La Guitarra by 373% to 27.2 million Ounces, Inferred Silver- Equivalent Resource Increased 204% to 20.2 million Ounces. The Coloso mine supplied most of La Guitarra's production from 2015 to 2018 before being placed on care and maintenance. The Coloso and Narareno block modelsutilized wireframe models developed by First Majestic Silver which have been validated. The Coloso veins average width is 1.5 meters and the Nazareno veins have an average width of 4.3 meters. The Coloso mine has over 12 kilometres ("km") of existing and accessible ramps, haulage ways, cross cuts, ventilation shafts, and development drives. The Nazareno mineralization is accessed from the Coloso workings by a one km meter haulage way and was under development when the mine was closed. The Guitarra Indicated Resources are contained in seven veins with a weighted average width (width x tonnes) for the Indicated Resources of 3.4 meters. The Guitarra mine has approximately 40 km of haulage ways, ramps, crosscuts, raises, and development drives. It is accessed from the surface at five primary levels along with several other hillside adits. A decline ramp accesses the San Rafael 1 and 2 areas and has two ventilation shafts. Sierra Madre management recognized that portions of the Guitarra veins and Santa Ana in the East District might be amenable to long-hole mining based on their previous mining experience at the Property and historic mining methods. The Los Angeles area in the Guitarra mine was found to have vein and stockwork mineralization in a configuration that could be amenable to long-hole mining methods. The Los Angeles mineralization is accessible on three haulage way levels, several ramps, and multiple development drives. Existing ore passes on the La Cruz, Los Angeles, San Francisco, and Garambullo levels connect to the San Rafael haulage way, the primary haulage way to the Guitarra flotation plant. The Santa Ana vein in the East District has an average width of 7.1 meters. First Majestic completed an approved Environmental Impact Statement (MIA) to develop Santa Ana. The operating area is called La Tlacotal, and the Company has a long-term land use agreement on the surface. Tillkännagivande • Sep 15
Sierra Madre Gold and Silver Ltd. Provides Update on District-Scale Exploration At La Guitarra Silver-Gold Mine Complex in Estado De Mexico, Mexico Sierra Madre Gold and Silver Ltd. provided an update on its exploration activities at the 100% owned past-producing La Guitarra Silver-Gold Mine Complex ("La Guitarra") in Estado de Mexico, Mexico, 130 km southwest of Mexico City. Beginning in February of this year, the company started a 2,000-scale geologic mapping program, first in the eastern portion of the Temascaltepec mining district and then progressing to the west side. This mapping program is the first-ever project-wide undertaking. It provides additional data for understanding the structural controls on the vein-hosted silver and gold mineralization. District-Scale Mapping by Sierra Madre: To date, surface mapping has delineated nearly 53 km of mineralized quartz veins, breccias, and stockwork zones. Mapping in the Eastern district has delineated over 37.9 km of veining. The dominant strike direction of veining is to the northwest, accompanied by a second set of veins, known as antithetic structures, striking more easterly. Both groups of veins host gold and silver mineralization, with hundreds of old shafts, cross cuts, adits, and prospect pits having been located. Host rocks for the veins are metasediments and andesites. Approximately one-half of the area mapped thus far is covered by recent basalt flows, with the veins exposed in erosional windows. Mapping has been completed over a significant portion of the West district. Thus far, over 15 km of veins have been located at the surface. While the principal vein systems, Guitarra, Coloso, and Nazareno, have been exploited, the vein swarm north of Guitarra has yet to be drill tested despite having numerous old shafts, adits, and prospect pits. Next Steps: A surface and underground sampling program will commence as soon as the rainy season is over. The results of this program will provide information on the most favorable structural settings for silver and gold deposition. Results from this work will be used to plan exploration drilling programs in the East and West districts. Tillkännagivande • Sep 08
Sierra Madre Gold and Silver Ltd. Provides Update on La Guitarra Progress Sierra Madre Gold and Silver Ltd. provided an in-depth update of its activities at the 100% owned past-producing La Guitarra Silver-Gold Mine Complex ("La Guitarra") in Estado de Mexico, Mexico, 130 km southwest of Mexico City. The Company's objectives are to complete a new resource estimate by year-end, followed up by a Mine Restart Study, which would include a cost study, mine plan, and a reserve estimate. Underground and plant rehabilitation, as well as a rebuild and refurbishment program of mine and plant equipment have also begun. The Company anticipates that, given adequate funding and assuming project execution tracks internal projections, restart of production at La Guitarra could be feasible within 20-22 months. The following programs are underway: The La Guitarra database consists of 1,408 drill holes totaling 236,000 metres of drilling; containing over 86,300 assays and 12,668 channel and mine samples. Raise and stope sample data, along with the actual production results are also being compiled to assure confidence in grade and width projections for the in-situ veins. The electronic database also contains 3-D surveying data with corresponding imaging of the underground workings and stopes at the La Guitarra, Coloso and Nazareno mines. Underground 3-D laser surveying is currently underway to augment and check the existing survey data. Surface surveying of historic drill hole collars is ongoing as part of the database audit. The resource estimation will consist of computer-generated block models of the larger deposits and polygonal block estimations on long sections, the latter being typical of mines operating in narrow vein type mineralization with distinct ore shoots. The three open pit deposits contained historic reserves of 6.8 million tonnes grading 0.75 g/t gold and 81 g/t silver at a combined strip ratio of 8:1, waste to ore. The geologic model used to generate the estimate was built from mineralized zone wireframed solids and an economic pit shell was used to generate the open pit estimates. The approach and methods used in the calculation of the historic estimate are reasonable for the period in time the estimates were compiled. The historic estimate cannot be verified by a Qualified Person and is historic in nature, the Company is not treating this historic estimate as a current mineral resource or reserve, and it should not be relied upon. Sierra Madre has determined that permitting for underground operations has a shorter time frame when compared to open pit mining and underground mining costs will compare favourably to those associated with an 8:1 open pit strip ratio. Previous operators have effectively used underground long-hole bulk tonnage mining at La Guitarra. Drill hole and mine samples in the three open pit areas have been reviewed to identify areas of mineralization which might possess the proper geometry and grade continuity needed to use long-hole drilling equipment. Priority was given to areas where minimal additional underground development would be required. Company staff and consultants have reviewed the underground mine and plant equipment to determine operational status. Maintenance and repair staff have been hired, all of which previously worked at the mine and are familiar with the equipment. The Company has five scoop trams, used to load and haul ore, in inventory, two of which are currently operational. Two dual arm jumbo drills for use in blasting production drives and haulage ways are also on-site. A rebuild/repair work program has begun on this equipment. The Company's Mining Department, composed of personnel who operated the mine for First Majestic, believes this equipment has the capacity to support a 500 tonne per day operation when fully operational. New explosive storage areas are being constructed underground in locations that will be more operationally efficient. Preventative ground stabilization work has been completed in a critical section of the main San Rafael haulage way. Much of the other equipment needed to resume operations is on site. Stationary air compressors and electrical substations are installed and functional. The current inventory includes approximately 30 jackleg drills and related equipment for use primarily in narrow vein production stopes. Electrical motors in the flotation processing plant, including 3 of the 4 ball mills, have been power tested and found to be operational. The crushing circuit was recently tested with 3 tonnes of waste rock and functioned as designed. The main operations water storage tank has been drained and repaired. Scaling and rust removal in the flotation cells has begun along with an evaluation of pumps and piping. While some pieces of equipment (long hole drill and haulage trucks) still need to be purchased or leased, the majority of the equipment needed to potentially restart the mine is in place and functional. The Company believes that building on the existing equipment and infrastructure, the La Guitarra mine could be restarted for a significantly lower cost compared to building a new processing plant and developing a new underground mine. All additional capital expenditures needed for the mine and processing plant will be determined when the cost portion of the Mine Restart Study is completed. Tillkännagivande • Aug 17
