Sierra Madre Gold and Silver – Q2 Operations and Financial Update At La Guitarra Mining Complex, 60k Meters Of Drilling Between La Guitarra and Del Toro Properties

Alex Langer, President and CEO of Sierra Madre Gold And Silver (TSXV: SM) (OTCQX: SMDRF), joins me to recap the Q2 operations and financial update at the La Guitarra silver-gold mine complex in Mexico, which includes 3 producing mines:  La Guitarra, Coloso, and Nazareno.   We look ahead to the 2-phase mill expansion and upcoming increased 30,000 meters of drilling planned across the La Guitarra District.  Additionally, we discussed the path forward at the recently acquired Del Toro mining complex, and the increased drill program to 30,000+ meters of drilling at the property starting in the second half of this year.

Q2 2026 Highlights

• Revenues: Silver revenues for the quarter totaled $5.0 million ($75.65 per ounce) and gold revenues totaled $4.3 million ($4,529 per ounce). Silver revenues for the quarter ended June 30, 2025 ("Q2 2025"), totaled $2.2 million ($33.36 per ounce) and gold revenues totaled $3.6 million ($3,272 per ounce).
• Adjusted EBITDA of $3.5 million for the six months ended June 30, 2026 ("H1 2026") compares to $2.6 million for the six months ended June 30, 2025 ("H1 2025").
• Gross Profit was $1.58 million for Q2 2026, as compared to $1.69 million for Q2 2025.
• Cash from Operations: the Company generated $1.89 million of cash from operating activities in H1 2026 as compared to $1.37 million in H1 2025.

• Cash and Cash Equivalents at June 30, 2026 totaled $22.2 million, with $25.0 million in working capital, compared to $13.2 million and $14.4 million at March 31, 2026, respectively.
• Daily Production is now reaching up to 672 tonnes per day ("tpd"), a 34% increase over the previous level of 500 tpd.
• Del Toro Acquisition: Following shareholder approval (April 28, 2026 news release) and Mexican Antitrust approval (announced May 22, 2026), the Company closed the acquisition of a 100% interest in the Del Toro silver mine, as announced on June 22, 2026. With this acquisition, Sierra Madre completed a concurrent financing for gross proceeds of CAD$57.5 million.
• Geologic mapping and sampling have started at Del Toro with a re-evaluation of surveys underway and drilling expected to start in mid-2027.
• East District Exploration: Following quarter-end, as released on July 14, 2026, Sierra Madre received approval to start drilling in the East District of the Guitarra complex. Target definition work is underway with drilling bids in hand for a long-hole sub-horizontal drill program planned from the Tlacotal property (a permitted area designated for mining). Drilling is expected to start in H2 2026.
• First Majestic Loan Repayment: As announced on July 8, 2026, the Company has fully repaid the US$5 million non-revolving, secured term loan with First Majestic Silver.

Operational Details

• Production: Ahead of the Phase I and II expansion plans, Sierra Madre selected a contractor to ramp up production from the higher-grade Coloso and Nazareno mines; contractor operations started mid-June. Sierra Madre miners and equipment are now focused on accelerating production at the Guitarra mine.
• Costs: The Q2 2026 cash costs were negatively impacted by the ramp up and development work at Coloso and Nazareno, leading to a significant share of production being sourced from development drives and out-of-resource, lower grade mineralization. While adding to top-line revenues, increased commodity prices also add to our cash costs through increased royalty payments and taxes. The strengthening Mexican peso against the US dollar, inflation impacts on inputs, and rising worker pay rates also affected costs.
• Recoveries: Gold and silver recoveries declined as the ongoing development work opened new mining areas and resulted in a blend of feed from three mining centres. Sierra Madre has built a metallurgical lab at the site to optimize the blending protocol.
• Power Generation: In Q2 2026, power outages continued due to weather incidents, increasing costs. Sierra Madre acquired a 1,250-kilowatt ("kW") back-up diesel generator for Coloso and Nazareno (installation is underway), plus two 1,500-kW back-up diesel generators for the plant. Installation of the two Guitarra generators was completed mid-August 2026 and are expected to be fully operational in September.
• Equipment: The transfer of a narrow-profile Muki jumbo drill to the Guitarra mine is expected to support development and production of narrower and higher-grade veins in the San Raphael area and of the Juliet vein. Following quarter end, the rebuild of a 0.5-yard scoop tram has reduced dilution and mining costs for the Juliet vein.
• Sierra Madre also purchased two haul trucks in April, to replace rental units used in the tailings buttress program and for Coloso haulage, which are expected to lead to cost reductions. Two scoops were also acquired to support increased mining rates with the expansion.
• Coloso and Nazareno: Mining restarted at the higher-grade Coloso underground mine at the end of Q1 2025 (estimated resource grades at Coloso are significantly higher in both silver and gold compared to the Guitarra mine veins[1]). In September 2025, Sierra Madre also announced the restart of mining at the Nazareno mine.
• At Coloso, dewatering of the lower levels has been accelerated and production from resource blocks below the existing workings is expected to start in the second half of 2026. Nazareno began full production from long-hole stopes on the 180 level in late April 2026.
