Silver: A Precious Metal with a Structural Twist
Silver is often grouped with gold as a precious metal and store of value, but the way it is produced sets it apart in a significant way. While gold is typically mined as the primary product, most silver is not. Instead, over 70% of global silver production comes as a byproduct of mining for base metals like copper, lead, and zinc.
This structural distinction creates a unique challenge for the silver market: supply does not respond directly to silver’s own price movements. As a result, silver can experience unexpected shortages and price spikes that catch investors and industries off guard.

Byproduct Production: What It Means and Why It Matters
In mining terminology, a byproduct is a material that is recovered incidentally during the extraction of a different primary metal. In the case of silver, that primary metal is often copper, zinc, or lead. Mines targeting these metals may recover silver as a secondary benefit, but silver is rarely the main reason for the operation.
This matters because base metal miners make business decisions based on the prices and demand for their primary metal—not silver. Even if silver prices surge, a copper miner won’t necessarily increase production unless copper prices justify it. That means silver’s supply is essentially "along for the ride" and doesn’t rise or fall in lockstep with silver’s own demand or price trends.
"Silver production is hostage to the economics of base metals," says David M, venture partner at Si Iver. "That’s why we see these periods of tightening supply even when silver prices are moving higher—because the decision to mine more silver is not in silver’s hands."

Why Silver Supply Is Price Inelastic
In economic terms, a price-inelastic supply means that even large changes in price don’t result in a significant change in the quantity produced. This is true for silver, whose supply remains largely unaffected by shifts in its own market. Unlike gold, where higher prices often lead to increased exploration and production, silver’s output is constrained by how much base metal mining is occurring globally.
This inelasticity has major implications:
* Limited responsiveness to rising prices – If silver demand rises rapidly, the market cannot quickly bring on more supply to meet it.
* Greater volatility – Price swings are often sharper and more exaggerated than in other metals.
* Vulnerability to supply disruptions – Events affecting base metal mines (even if unrelated to silver) can drastically impact silver availability.

Disruptions in Base Metal Mining: Ripple Effects on Silver
One of the more unpredictable aspects of silver’s byproduct status is how events in unrelated metal markets can significantly alter silver supply. For example:
* Labor Strikes – A strike at a zinc mine in Mexico may have nothing to do with silver, but if that mine produces large quantities of byproduct silver, global supply is immediately affected.
* Environmental or Political Issues – Changes in mining policy in countries like Peru or Bolivia can delay or halt base metal projects, cutting silver supply in the process.
* Pandemic Shutdowns – In 2020, COVID-19 led to temporary mine closures across Latin America, particularly in Peru and Mexico. Although some of these mines primarily produced copper or lead, global silver output dropped by over 5%, sending silver prices sharply higher.
Because silver isn’t the main product in most of these mines, \*\*there’s often little financial motivation to continue production during such disruptions—\*\*even if silver prices are rising.

The Role of Primary Silver Mines: Too Few, Too Slow
Primary silver mines—those that exist specifically to mine silver—do exist, but they account for less than 30% of global production. These mines are more sensitive to silver prices and can, in theory, ramp up output in response to price spikes. But there are limitations:
* Long development timelines – It can take 5 to 10 years to bring a new silver mine online due to permitting, exploration, and construction.
* Declining ore grades – Many primary silver deposits today contain lower concentrations of silver, meaning more material must be processed to extract the same amount, raising costs.
* Limited scale – Even the largest primary silver mines cannot fully offset global shortfalls caused by disruptions in base metal mining.
"There’s a fundamental mismatch between how silver is priced and how it’s produced," explains Keith Neumeyer, Venture Partner at Si Iver. "Unless more capital flows into primary silver production, the market will remain tight, especially as industrial demand keeps rising."

Silver Demand Is Growing—But Can Supply Keep Up?
Silver’s demand profile has evolved. Once dominated by jewelry and coinage, modern silver demand is increasingly industrial. Key growth areas include:
* Solar panels – Silver is a critical component in photovoltaic (PV) cells, and demand is expected to grow as the world accelerates toward clean energy.
* Electric vehicles (EVs) – Each EV uses up to twice as much silver as a traditional gas-powered car.
* Electronics – Silver’s conductivity makes it ideal for 5G infrastructure, semiconductors, and other high-tech applications.
These trends point to a long-term rise in silver demand, but if the majority of production remains tied to base metals, the supply chain may not be able to keep up. That mismatch could lead to sustained deficits and higher prices.

Volatility and Opportunity for Investors
Silver’s unique supply situation presents both risks and opportunities. For investors, the upside lies in sharp rallies during periods of high demand or constrained supply. Silver’s relatively small market (compared to gold) means it can rise quickly when investor sentiment shifts.
However, the downside is that silver is also more vulnerable to downturns. If industrial demand softens—due to recession or manufacturing slowdowns—and base metal mining increases due to strong copper or zinc prices, silver may experience an oversupply and sharp price declines.
Understanding these dynamics is critical for anyone investing in silver or using it for hedging purposes.

A Metal With a Mind of Its Own
Silver may resemble gold in some ways, but its byproduct nature sets it apart. Because most silver is produced incidentally while mining other metals, its supply is less responsive to its own price and more influenced by the base metals industry. This makes silver uniquely volatile, prone to unexpected supply shocks, and difficult to forecast.
For industries relying on silver—and for investors trying to navigate its ups and downs—understanding this structural dynamic is essential. As green technology drives long-term demand and base metal mining faces mounting regulatory and environmental hurdles, silver may enter a new era of supply constraint and price volatility.
