One of Mexico's Big Silver Mines Produced 41% Less. Silver Fell Anyway.

A major silver mine just produced 41% less silver than it did a year ago. Silver spent the same week falling.

If you learned economics from a textbook, that looks backwards. Less supply, higher price. Simple. The market apparently skipped that chapter.

What Happened at San Dimas

On October 8, First Majestic reported that its San Dimas mine produced 859,869 ounces of silver in the third quarter, down 41% from the same period last year. The company blamed an ongoing labour dispute that slowed the flow of fresh ore, which lowered the grades being milled. The release says the dispute affected operations for 12 days in the quarter.

It wasn’t just one mine’s bad quarter. First Majestic’s total attributable silver production was 3,440,447 ounces, down 11% year over year. The company has no firm date for resolving the dispute, only a stated aim of getting back to normal operations as quickly as possible.

One mine, one company, one strike. I’m not telling you this moves the global market by itself. It doesn’t. But it isn’t happening in a vacuum, either. Kitco, citing Mexican government survey data, reported that Mexico’s July silver output was 10.56 million ounces, up 1.7% from June but still 2.3% below July 2025.

The Price Didn’t Read the Press Release

Here’s what silver did. On Wednesday, after hotter inflation data, Kitco had spot silver at $57.89, down 1.97%, and said higher oil prices amplified the selloff through industrial-demand worries. On Thursday morning, silver bounced about 2% to roughly $56.62 as Treasury yields fell. For reference, Kitco’s October 5 report had silver at $60.99.

So within about ten days, silver went from just under $61 to the mid-$50s. During that stretch, a major producer told the world it was digging out far less metal.

That’s the lesson. In the short run, silver doesn’t trade on mine output. It trades on yields, the dollar, oil, and fear about factories. Supply problems are a slow story. Rate-hike odds are a fast one, and fast wins most weeks.

The Bottom Line

I’d love to give you a clean “shortage means price up” narrative. It would make for a better post. It would also be wrong for this week.

Here’s what I’d watch instead. First, whether the San Dimas dispute gets resolved, since that determines whether the Q3 drop is a blip or a trend. Second, whether Mexico’s monthly output keeps running below last year. Third, whether the yield-and-dollar story that has been driving silver eases up.

For stackers buying physical on a schedule, a falling spot price and a shrinking supply of new metal can both be true at once. Neither one tells you what next month’s price will do. The mine report is the slow signal. The yield chart is the loud one. Know which is which.
