Vancouver, British Columbia--(Newsfile Corp. - November 13, 2025) - Sierra Madre Gold and Silver Ltd. (TSXV: SM) (OTCQX: SMDRF) ("Sierra Madre" or the "Company") is pleased to provide financial results for the quarter ended September 30, 2025 ("Q3 2025"). Unless otherwise noted, all amounts are expressed in U.S. dollars.

Alex Langer, Chief Executive Officer, commented, "Q3 revenues of US$5.5 million and gross profit of US$ 1.7 million continue to show quarter-over-quarter growth, notably with a 27% increase to Adjusted EBITDA over Q2 2025, driven by stronger realized silver and gold prices and highlighting our operating leverage. We continue to optimize mining and milling performance, advance into new faces, and add equipment to increase production and reduce costs. At the same time, the Company is ramping up operations at the Coloso and Nazareno mines within the Complex as development progresses, de-watering efforts advance, and access to higher-grade zones progresses. These impacts are expected to be reflected as early as Q4 and into 2026. Longer term, we remain focused on completing a plant expansion, with the first phase — ramping up by over 50% from current 500 tpd levels to 750 tpd - 800 tpd by Q2 2026 — now underway. We have acquired surface and underground equipment for this expansion, including the second crusher with work in progress for its installation. Excavation of the area for the thickener has started, with Purchase Orders issued to start the engineering and civil works for the paste plant and the fabrication of the tank."

Mr. Langer continued, "Quarterly silver and gold production from La Guitarra complex in Mexico was more affected than expected by power outages. The mill was only able to produce ~90% of nameplate capacity because of these outages in Q3, due to a longer and heavier rainy season, but we anticipate a stronger Q4 now that the rains ended in late October. Despite these downtimes, our financial performance continues to improve. The company expects to have a backup power generation system in place prior to the 2026 rainy season. We are also pleased to now be conducting exploration in the under-explored East District of La Guitarra, with a US$3.5 million exploration program underway and drilling expected to kick off in Q2 2026."

Q3 2025 Highlights

• Net revenues for Q3 2025 increased by 3.0% to $5.52 million or $35.94 per silver-equivalent ("AgEq") ounce sold as compared to $5.36 million and $30.87 per AgEq ounce in the quarter ended June 30, 2025 ("Q2 2025").
• Sales: In Q3 2025, the Company sold 68,741 ounces of silver ("Ag") and 960 ounces of gold ("Au") or 153,583 AgEq ounces, based on the ratio of Au and Ag prices realized for each shipment in the period.
• Cost of sales was $3.82 million for Q3, or $24.85 per AgEq ounce sold compared to $4.07 million for Q2, or $23.45 per AgEq ounce sold.
• Cost Drivers: Cash costs for Q3 increased due to the impact of the strengthening of the Mexican peso versus the US dollar on MXN-denominated mining costs, the impacts of the rainy season in Mexico, including the accompanying power outages, on production volumes. For Q3, cash costs were $24.59 per AgEq ounce sold, as compared to $23.56 in Q2.
• Mill Downtime: Rainy season-related power outages resulted in over 187 hours of mill downtime in Q3 2025, which represents ~47% of the total mill downtime for the quarter. Sierra Madre continues to evaluate power generation options with plans to have power redundancies available for the start of the next rainy season in Q2 2026.
• Gross Profit was $1.70 million for Q3 2025 ($1.29 million for Q2 2025).
• Adjusted EBITDA increased by 27% to $1.86 million for Q3 2025 as compared to $1.46 million for Q2 2025.
• All-in-sustaining costs per AgEq ounce sold of $34.42, compared to $30.10 in Q2 2025. This quarter-on-quarter increase was due to the start of equipment purchases and mine development expenditures funded by the financing closed in July 2025.
• Current assets, including cash, totaled $16.9 million at September 30, 2025 ($5.93 million at June 30, 2025).
• Closed C$19.5M Private Placement: On July 24, and July 31, 2025, the Company closed the first and second tranches, respectively, of a C$19.5 million brokered private placement. The key participants in the financing were Franklin Templeton, Eric Sprott and Commodity Capital, with strong participation by the management of the Company.

Additional Operational Details

• Equipment Purchases: In the nine months ended September 30, 2025, the Company incurred $2.03 million on acquiring mining and mobile equipment and refurbishing underground equipment.
• Mine Operations: Milled 38,433 tonnes of material, with silver recoveries averaging 76.96% and gold recoveries averaging 75.55%.
• In Q2 2025, the Company milled 41,235 tonnes of material, with silver recoveries averaging 76.62% and gold recoveries averaging 77.95%.
• Production: Produced 67,785 ounces of silver and 967 ounces of gold (vs. production of 66,011 ounces of silver and 1,048 ounces of gold in Q2 2025).
• Concentrate Deliveries: Completed deliveries totalling 802 dry metric tonnes of silver/gold concentrates (780 dry metric tonnes of silver/gold concentrates delivered in Q2 2025).
• Development: $855,000 spent on mine development in Q3 2025.
• Exploration: $516,000 spent on exploration and evaluation activities in the nine months ended September 30, 2025.
• Coloso Mining: At the end of Q1 2025, Sierra Madre made the decision to re-start production at the Coloso underground mine and subsequently, on April 29 2025, announced the start of mining at Coloso within the Guitarra Complex with the first stope being brought into production. The estimated resource grades at Coloso are significantly higher in both silver and gold compared to the Guitarra mine veins¹.
• Since initiating production at Coloso, the Company has focused on developing more production stopes. Dewatering of the lower mine levels has been accelerated and it is anticipated that production from resource blocks below the existing workings will commence next year.
• La Guitarra Expansion Plans: On September 8, 2025, Sierra Madre announced plans for a two-stage plant expansion at La Guitarra. The first phase would grow capacity by more than 50%, to 750 tpd - 800 tpd, by Q2 2026. A subsequent expansion would increase capacity to more than 100% of current capacity, or 1,200 tpd - 1,500 tpd, by Q3 2027. The expansion is expected to be funded from the Company's treasury and cash flow.
• To date, Sierra Madre has acquired surface and underground equipment for this expansion, including the second crusher with work in progress for its installation. Excavation of the area for the thickener has started, with purchase orders issued to start the engineering and civil works for the paste plant and the fabrication of the tank.
• Nazareno Development Started: As outlined in the Company's September 30, 2025 press release, underground development has started at the Nazareno mine within La Guitarra, with over 700 tonnes of mineralized material delivered to the Guitarra plant from Nazareno as of September 30, 2025. This material was not included in the 2023 Mineral Resource Estimate.
• Nazareno is accessed via a one-km underground drive from the Coloso working. Mineralization in this area comes from two closely spaced veins with the internal host rock containing economically interesting stockwork mineralization. The width of the economically interesting mineralization averages 4.5 meters, suitable for low cost long-hole stoping techniques.
• East District Exploration Program: On October 23, 2025, Sierra Madre announced the start of a $3.5-million exploration program at the East District of La Guitarra; the District covers the historic Temascaltepec mining area. The US$3.5-million East District exploration program is first focusing on drill target definition through mapping, surveying, mapping and sampling of historic workings, and a structural analysis in order to determine the geologic controls of historically mined mineralization. This program is estimated to take nine months to complete and, upon completion, a 20,000 to 25,000 metre drill program would then be undertaken to further assess the targets' economic potential, expected to start in Q2 2026.

Outlook

• With the end of the rainy season in late October, the Company expects stronger fourth-quarter production as power outages subside and operations restart progresses at the Coloso and Nazareno mines with development, de-watering and access towards higher-grade areas. Following the closing of the July 2025 financing, the Company plans to purchase additional equipment for enhanced mine efficiency and increased overall grades, backup power generation, and production volumes.

Cautionary Note Regarding Production Decisions

The Company's decision to place the mine into commercial production, expand a mine, make other production related decisions, or otherwise carry out mining and processing operations, is largely based on internal non-public Company data and reports from previous operations and the results of test mining and processing. The Company is not basing any production decisions on NI 43-101 compliant reserve estimates, preliminary economic assessments or feasibility studies and, as a result, there is greater risk and uncertainty as to future economic results from the Guitarra Mine Complex, including increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with developing a commercially mineable deposit, and a higher technical risk of failure than would be the case if a feasibility study were completed and relied upon to make a production decision.
