Silver Rises Over 120% YTD 
Published: 09-15-2026, 04:26 pm
Byproduct silver mining means producing silver as a side output of copper, lead, and zinc mines. It is not mines built to find silver on its own. That’s why roughly 70-80% of the world’s silver supply can’t respond to a higher silver price. A dedicated gold or silver mine could. A byproduct mine, in contrast, mostly can’t.
Three August 2026 disruptions made this visible. A Chilean weather shutdown, a Mexican blockade (now resolved), and a Peruvian production decline together removed an estimated 1.1 million ounces of silver supply. That’s about 2.4% of the Silver Institute’s projected 46.3 million ounce 2026 deficit. Silver’s own price caused none of it. That’s exactly why it still matters.
Specifically: when supply is a byproduct of another metal’s economics, the silver market has almost no lever to pull when it needs more metal. That holds whether or not any single disruption is still active. Crux Investor first reported the fuller compilation of the three events on September 4, 2026.
Key Takeaways:
- Three unrelated August 2026 events — a weather-driven guidance cut in Chile, a now-resolved community blockade in Mexico, and a June production decline in Peru — combined for an estimated 1.1 million ounce reduction in silver supply. That’s roughly 2.4% of the Silver Institute’s projected 2026 deficit of 46.3 million ounces.
- Endeavour Silver has resolved the Mexico disruption at its Terronera mine: operations resumed August 24, 2026, per the company’s own reporting.
- Roughly 70-80% of global silver supply is a byproduct of copper, lead, and zinc mining. A higher silver price does not reliably bring more silver to market as a result.
- 2025 is the Silver Institute’s fifth confirmed consecutive deficit year. 2026 is forecast to be the sixth, but that remains a projection until the year closes.
- The structural argument — supply that can’t respond to price — is the case for physical, allocated ownership over a paper claim. That holds regardless of any single mine’s current operating status.
What Happened in August, and Is It Still Happening?
Here’s the mechanism in one paragraph, extractable on its own: only a minority of mines dig for silver on purpose. Most of it comes out of the ground because someone was digging for copper, lead, or zinc. Silver, notably, just rode along. Antofagasta, for example, cut its 2026 copper-production guidance on August 13. Severe weather had shut its Los Pelambres operation in Chile — a copper mine that also produces silver as a byproduct, per Crux Investor’s reporting.
Meanwhile in Mexico, an Ejido community blockade halted Endeavour Silver’s Terronera mine in Jalisco, starting August 12. The company’s own press releases confirm the resolution. Specifically, the community lifted the blockade, and Endeavour resumed full operations on August 24, 2026. That’s three weeks before we wrote this article — not, therefore, an ongoing disruption. In Peru, similarly, government statistics agency INEI reported silver production down 9.0% year-on-year for June 2026. That’s a data point from earlier in the summer — not, in other words, a live event.
Add the three together and Crux Investor puts the combined production impact at roughly 1.1 million ounces. That’s about 2.4% of the year’s projected deficit — a real, if modest, subtraction from a market that was already short. It is also, as of this writing, a matter of record rather than breaking news. Specifically: Endeavour has already resolved the Mexico leg, and the Peru figure predates this article. Only the Chilean guidance cut, similarly, is anywhere close to current.
The Knowledge That Changes Everything
Two essential guides — yours free. Understand why gold matters and why fiat currencies always fail.
Why Can’t Silver Mine Supply Increase When Silver Prices Rise?
Because most silver producers aren’t making a decision about silver at all. Roughly 70-80% of global mine supply, notably, is byproduct output. Copper, lead, or zinc economics drive the decisions that matter instead — expanding a pit, running a smelter harder, approving a new project. A silver price that doubles overnight doesn’t change any of those decisions. Silver, in other words, was never the reason the mine exists. Oliver Turner, an executive at primary silver producer Americas Gold & Silver, put it directly in comments reported by Crux Investor. Byproduct mines “can’t just turn on more silver supply when the world needs it,” he said. Their output, instead, depends on an entirely different metal’s supply chain. In his example, copper mines needed sulfuric acid, and that supply chain ran through shipping disruption near the Strait of Hormuz.
Is 2026 Really the Sixth Straight Silver Deficit Year?
The Silver Institute’s World Silver Survey 2026 puts this year’s projected shortfall at 46.3 million ounces. That would make it a sixth consecutive year of demand outrunning mine supply plus recycling, if 2026 closes that way. It’s worth being precise here, though: 2025 is the fifth confirmed deficit year, with final data in hand. 2026 remains a forecast until the year closes. The Silver Institute reports final figures the following spring, typically. Treat “sixth consecutive year” as the expected outcome, not yet a settled fact. That distinction matters, crucially, if you’re citing this figure six months from now and the final number has moved.
How Much of the 2026 Deficit Do August’s Disruptions Actually Explain?
Not much, on their own — about 2.4%, or 1.1 of the 46.3 million ounces. That’s the honest number, worth stating plainly instead of inflating it. Three named disruptions in three countries did not “cause” a shortage that predates all of them by five confirmed years running. What they demonstrate, instead, is structural, not causal. A market already running short has, notably, essentially no spare capacity to absorb even modest supply losses. In other words, the supply side has no fast-response mechanism at any price.
Is the Silver Deficit Getting Worse, or Just More Visible?
Both, in different ways. The deficit itself, measured in ounces, continues a pattern running since 2021 — not a new development August created. What August did was make the mechanism visible in a way a single annual survey number doesn’t. Three specific, dated, verifiable incidents illustrated the same constraint. Each came from a different angle: weather in Chile, community relations in Mexico, ore grade and informal-mining regulation in Peru. None of them, notably, was price-related. Registered COMEX silver inventory has also been drawing down against this backdrop, though this article does not independently re-verify the current figure.
Why Does a Copper Mine’s Weather Problem Matter More Than a Silver Mine’s?
The obvious read is that a copper mine’s weather problem is a copper story that happens to touch silver. The more useful read is the opposite: the copper mine’s weather problem is the silver story. GoldSilver’s Silver Price Outlook for September 2026 made a related point: the physical market is running tighter than the paper price alone would suggest. This is why: industries that don’t care about silver now control its supply side. A primary silver producer facing a higher silver price has every incentive to expand output. A copper company facing a higher silver price, by contrast, has almost none. Silver is a rounding error in its revenue, so its capital allocation decisions get made on copper economics, full stop.
That’s the second corner: the byproduct structure isn’t just a supply-side inconvenience. It’s a structural reason a persistent deficit can run for years without market forces closing it, the way textbook supply-and-demand would predict.
That argument doesn’t weaken as each individual mine returns to normal operation. Over a five-year horizon, it actually strengthens. The pattern recurs in different forms every year: weather, community relations, ore grade, and regulatory uncertainty around informal mining in Peru’s unresolved REINFO process. None of it, crucially, is silver-price-sensitive.
What Does This Mean for Gold, Silver, and Platinum Investors?
For an investor weighing paper exposure — an ETF, a futures contract — against physical ownership, this is precisely the distinction that matters. A paper claim on silver is a claim on a price. Physical silver, by contrast, is a claim on a specific, finite quantity of actual metal. Per the mechanism above, that metal is structurally hard to replace. The supply side of this market, notably, has no fast lever.
Meanwhile, the demand side keeps growing: silver’s industrial share, spanning solar, electronics, and electric vehicles, still runs 50-55% of annual demand per Silver Institute data. Put those two facts together, and, as a result, the case for owning the physical asset gets stronger every year the deficit persists. That’s not, however, because any single mine disruption is dramatic. It’s because, instead, the underlying structure isn’t going away. In short, that’s the case for holding metal outside a paper claim on it — in allocated, identifiable ownership rather than an unallocated pool. The distinction matters most exactly when supply is tightest and counterparty promises are hardest to test.

Frequently Asked Questions
What is byproduct silver mining, and why does it matter for the silver price?
Byproduct silver mining is production of silver as a secondary output of mines built to extract copper, lead, or zinc. Roughly 70-80% of global silver supply comes from these operations. It matters because those mines make output decisions based on the primary metal’s economics, not silver’s — specifically, whichever metal actually pays for the mine. As a result, a rising silver price does not reliably summon more silver supply the way it would for a dedicated silver mine.
How is byproduct mining different from primary silver mining?
A primary silver mine, specifically, exists because silver itself is economic to extract. As a result, its owners respond to the silver price directly. A byproduct operation’s silver output, in contrast, is a function of decisions made about an entirely different metal. A copper mine, instead, expands or contracts on copper economics — any silver that comes along is incidental to that decision.
How do I know if a silver supply disruption is still active or already resolved?
Check the operator’s own public disclosures rather than secondary compilations. In the case of Endeavour Silver’s Terronera mine, the company’s own press releases confirm the timeline. The blockade began August 12, 2026. The community lifted it, and operations resumed August 24. That’s a fact, notably, easy to miss if a compiled report doesn’t carry the update.
What is the risk of holding paper silver versus physical silver during a supply deficit?
Paper silver instruments, such as an ETF or a futures contract, represent a claim on price. They are not a claim on a specific, identifiable quantity of metal. They carry, however, counterparty and structural risk that physical, allocated ownership does not. During a persistent supply deficit, that distinction becomes more consequential, not less.
What happens if the silver deficit keeps widening?
A widening deficit means, specifically, that demand keeps exceeding mine supply plus recycling. That draws down above-ground stockpiles that took decades to build, and silver’s byproduct-dominated supply structure means mine supply and recycling can’t replenish them quickly. If the pattern continues, the physical market’s ability to meet demand at current prices comes under continued pressure. That changes only if mine supply responds faster, or industrial demand falls more than forecast.
Is the silver deficit confirmed for 2026, or still a forecast?
It is still a forecast as of this writing. The Silver Institute’s 46.3 million ounce figure for 2026 is a projection. 2025 is the most recent year with confirmed final data, and it was the fifth consecutive deficit year. In other words, the Silver Institute won’t confirm 2026’s status as a sixth consecutive year until it publishes final figures, typically in the following year’s World Silver Survey.
