Vancouver, British Columbia--(Newsfile Corp. - May 7, 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 March 31, 2025 ("Q1 2025"). All amounts are expressed in U.S. dollars. The Company will participate in a webinar to discuss the financial results on Tuesday, May 13 at 11am ET. Registration details below.

Alex Langer, Chief Executive Officer, commented "We are very pleased with the Q1 results, with $4.8 million in revenues and a gross profit of $1.2 million, including $535,000 in cash generated from operations, reflecting an exciting first quarter of commercial operations at our Guitarra silver-gold mine complex. I would like to highlight our consistent production and revenue growth month over month since the Guitarra restart. We are expecting accelerating revenue growth for Q2 and Q3."

Mr. Langer continued, "These results establish a solid base for further growth as we ramp up the Coloso Mine in the complex, which just recently started supplementing higher-grade feed to the plant last month. The Sierra Madre team continues to fine-tune the operation with new mining faces being accessed and significant equipment purchases being made from cash flows. We expect continued improvements in the mining and milling processes as the site runs at the commercial throughput capacity of 500 tonnes per day."

Q1 2025 Highlights

  • Net Revenues: Silver revenues for the quarter totalled $2.34 million ($31.13 per ounce) and gold revenues totalled $2.89 million ($2,828 per ounce).

  • The Company sold 75,137 ounces of silver ("Ag") and 1,022 ounces of gold ("Au") or 165,093 silver equivalent ("AgEq") ounces, based on the ratio of Au and Ag prices realized for each shipment in the period.

  • Cost of sales was $3.6 million, approximately $21.84 per AgEq ounce sold.

  • All-in-sustaining costs per AgEq ounce sold of $28.98 per ounce, compared to $32.18 in Q4 2024.

  • Gross Profit was $1.2 million.

  • Cash provided by operating activities was $535,000.

  • Current assets, including cash, totaled $4.3 million at March 31, 2025, up from $3.5 million in Q4 2024.

Q1 2025 Operational Details

  • Mine Operations: Milled 39,167 tonnes of material, silver recoveries averaged 79.21% while gold recoveries averaged 78.77%.

  • Production: Produced 70,176 ounces of silver and 1,001 ounces of gold.

  • Concentrate Deliveries: During the quarter ended March 31, 2025, completed deliveries totalling 871 dry metric tonnes of silver/gold concentrates.

  • Coloso Mining: On April 29 2025, Sierra Madre announced the start of underground mining at the Coloso mine within the Guitarra Complex. The estimated resource grades at Coloso are significantly higher in both silver and gold compared to the Guitarra mine veins. During the ramp up of Coloso mining, various blending percentages for mill feed will be tested to ascertain best recovery procedures.

  • The Company anticipates improved head grades of the mineralized material in 2025 and a reduction in mining costs on a per-ounce basis going forward with Coloso expected to be a key driver of these improvements.

  • Equipment Purchases: Spent $378,000 to acquire mining and mobile equipment and refurbish underground equipment used in mine development. A large front-end loader and excavator were purchased, replacing costly rental equipment. Three personnel transport vehicles for both surface and underground work were also purchased, helping to accelerate the opening of the Coloso mine. A rebuilt engine and transmission were acquired for the low-profile underground haul truck, significantly extending its working life. After the end of Q1, a second explosives truck was purchased for use at Coloso and as backup for Guitarra.

  • Development: Development work was accelerated in Q1 2025, focusing on access to the larger higher-grade blocks defined in the 2023 resource estimate. The newly discovered veins, outside the existing resources, also required additional development work to ready them for stope production. This focus on development will result in the Company having more mineralized material available for processing in the later part of 2025. The diverting of equipment to development work was offset by processing low cost retaques, old backfill that contains economically interesting material, from areas that were mined in the 1990's when the mine cutoff was 8 to 10 grams per tonne gold-equivalent.

  • Hiring: The company has hired a degreed metallurgist with extensive flotation experience as Process Plant Superintendent, to oversee the proper blending of Coloso material with the current Guitarra mill feed. The metallurgist will also manage more in-house metallurgical testing. A civil engineer was hired to oversee the ongoing tailings dam work and other construction projects. Both of these hires reduce the Company's reliance on outside contractors and engineering firms.

  • Successful Transition to Commercial Production: In July 2024, the Company commenced test mining and milling at Guitarra, which was designed to provide further information on the current actual mining and milling costs to further assess the internal mine plan. The test program, underground development, and commissioning activities continued until December 31, 2024, when it was determined that the asset was consistently reaching the operating levels intended by management. On January 1, 2025, the Company declared commercial production at Guitarra, as announced on January 9, 2025.
