Mexico has quietly become one of the most active arenas for silver mine consolidation over the past three years, and the momentum is not slowing down. The country has long been the world’s largest silver producer, but a combination of elevated metal prices and tighter regulatory enforcement under the 2023 Federal Mining Law reform has reshaped how companies invest and operate there. That environment has created an unusual opportunity: mid-tier producers looking to sharpen their focus are offloading idle assets, and junior companies with the appetite and the financing are stepping in to acquire them.
The clearest example of this at the top of the market came in 2025, when Pan American Silver Corp. (NYSE: PAAS, TSX: PAAS) completed its $2.1 billion acquisition of MAG Silver Corp., significantly increasing its exposure to high-grade silver through MAG’s 44% stake in the Juanicipio Mine in Zacatecas, one of Mexico’s premier silver-gold operations. At the other end of the scale, junior and small-cap companies have been picking up past-producing assets that larger operators set aside during periods of lower prices or operational restructuring. Rising metal prices and improved technology are driving a redevelopment wave at old mines, though experts caution that buyers may inherit environmental remediation liabilities, making careful assessment essential.
It is within this backdrop that Sierra Madre Gold and Silver Ltd. (TSXV: SM) (OTCQX: SMDRF) has made its second significant move in as many years. On June 22, 2026, Sierra Madre announced the closing of its acquisition of the Del Toro Silver Mine in Zacatecas, Mexico, from First Majestic Silver Corp. (NYSE: AG, TSX: AG, FSE: FMV) in a deal valued at up to $60 million. Del Toro is an underground silver mine and processing facility in Zacatecas that was operated by First Majestic from 2013 until 2020, when it was placed on temporary suspension to improve overall operating cash flows and profit margins.
This is not the first time these two companies have done business together. Sierra Madre acquired the La Guitarra mine from First Majestic in 2023 and commenced commercial production there in January 2025. That first transaction established First Majestic as a significant shareholder in Sierra Madre, and the relationship has deepened with each subsequent deal. The Del Toro acquisition is essentially a continuation of a strategy Sierra Madre has been executing with discipline: identify past-producing assets with existing infrastructure, acquire them at reasonable cost, and work toward a restart.
Del Toro includes three fully permitted underground mines, a 3,000-tonne-per-day flotation processing circuit, and numerous historic mines, with more than 62.5 kilometres of development already in place. The site holds a historic resource totalling 7.57 million ounces of silver equivalent in the measured and indicated category and 11.18 million ounces in the inferred category. For a junior company, inheriting that level of existing development work is a meaningful advantage. Building comparable infrastructure from scratch would cost considerably more and take considerably longer.
The deal structure is straightforward. Sierra Madre paid $20 million in cash and issued approximately 10.87 million shares to First Majestic at closing, with a further $10 million due within 18 months in cash or shares. Beyond that, two additional milestone payments of $10 million each are tied to performance targets: one if the company demonstrates a resource of at least 100 million silver-equivalent ounces within four years, and another if Del Toro achieves commercial production of at least 4,000 tonnes per day within five years. To fund the initial closing, Sierra Madre completed a brokered private placement that raised approximately $40.7 million (CA$57.5 million), led by Beacon Securities with participation from Canaccord Genuity Corp. and BMO Capital Markets, among others.
Alex Langer, Sierra Madre’s President and Chief Executive Officer, was direct about what comes next: “The acquisition of Del Toro marks an important step for Sierra Madre Gold and Silver as we advance towards mid-tier silver production. A past-producing asset of this scale is a complementary addition to our Mexico-focused silver portfolio. With existing production infrastructure in place, our focus now turns to near-term resource expansion drilling, with approximately 30,000 metres planned. This program is expected to support an updated Mineral Resource estimate, followed by a potential mine restart, positioning the asset for a return to cash flow generation. We see significant upside at Del Toro, both from resource growth and restart potential.”
For First Majestic, selling Del Toro continues a broader portfolio rationalization. The company has been focused on its four operating mines in Mexico and the restart of the Jerritt Canyon Gold Mine in Nevada and shedding an idle asset while retaining upside through milestone payments and a continued equity stake in Sierra Madre makes strategic sense. Mining investment in Mexico grew modestly to $5.063 billion in 2024, a 2.1% increase from 2023, as companies navigated new permit and concession requirements. In that environment, capital allocation discipline matters, and holding a suspended mine with no near-term restart plan is a drag on resources.
What this deal ultimately reflects is the layered nature of Mexico’s silver consolidation. The largest transactions involve billion-dollar deals between major producers. The quieter ones, where junior companies absorb the assets that bigger players no longer want to manage, are where the real operating risk is taken. Sierra Madre is taking that risk deliberately, and Del Toro represents a bet that two producing or near-producing silver mines in Mexico are worth more together than either would be on their own.
