Silver production defined Silver is a precious metal mined primarily as a byproduct of copper, zinc, lead, and gold mining, rather than as a primary extracted commodity in its own right. Approximately 70–75% of global silver supply comes from mines where silver is a secondary or tertiary metal — not the primary economic target. Total global silver mine production runs approximately 820–870 million troy ounces (25,500–27,000 metric tonnes) per year. Mexico leads global production, followed by China and Peru. The price benchmark is set through the LBMA Silver Price auction in London, published in US dollars per troy ounce.

Silver as a Byproduct: Understanding the Production Context
Silver is unusual among major commodities in that most of it reaches the market as a consequence of mining something else.
When a copper mine processes its ore, the ore contains trace to moderate concentrations of silver — typically 1–20 grams per tonne of ore. The silver is captured during the copper refining process and eventually refined to silver bullion. The mine’s economic decision-making is driven by copper prices and copper ore grades; silver is a byproduct that provides incremental revenue but rarely determines whether a mine operates.
The approximate breakdown of silver supply by mine type:
| Mine Type | Approximate Share of Global Silver Production |
|---|---|
| Primary silver mines | ~25–30% |
| Lead-zinc mines (silver byproduct) | ~30–35% |
| Copper mines (silver byproduct) | ~20–25% |
| Gold mines (silver byproduct) | ~10–15% |
This byproduct structure has a significant market implication: silver supply is relatively inelastic to silver prices in the short to medium term. If the silver price doubles, a copper mine does not meaningfully change its production schedule for the sake of the silver byproduct — it’s still driven by copper. New primary silver mines take 10–15 years to develop, so the supply response to price signals is slow.
This inelasticity makes silver more price-volatile than commodities where producers can quickly adjust output in response to price. A demand surge for silver (industrial, investment, or both) cannot be met quickly with additional primary mining supply.
USGS data: The US Geological Survey (USGS) is the primary authoritative source for global silver production statistics, published annually in the USGS Mineral Commodity Summaries. The data cited below reflects USGS estimates for 2023–2024.
Top Silver-Producing Countries: 2024 Rankings
Global silver mine production, approximate rankings (2023 USGS data, 2024 preliminary estimates):
| Rank | Country | Estimated Production (Moz/year) | Approximate Global Share | Primary Mining Context |
|---|---|---|---|---|
| 1 | Mexico | 220–230 Moz | ~25% | Mix of primary silver and lead-zinc byproduct |
| 2 | China | 110–120 Moz | ~13% | Primarily lead-zinc and copper byproduct |
| 3 | Peru | 100–115 Moz | ~12% | Lead-zinc and copper byproduct; some primary |
| 4 | Chile | 55–65 Moz | ~7% | Primarily copper byproduct |
| 5 | Russia | 50–55 Moz | ~6% | Lead-zinc, copper byproduct |
| 6 | Poland | 42–48 Moz | ~5% | Copper byproduct (KGHM’s Rudna/Polkowice-Sieroszowice) |
| 7 | Australia | 40–50 Moz | ~5% | Lead-zinc (Cannington); copper byproduct |
| 8 | Bolivia | 35–40 Moz | ~4% | Primary silver and lead-zinc byproduct |
| 9 | United States | 30–35 Moz | ~4% | Gold and copper byproduct |
| 10 | Argentina | 28–33 Moz | ~3% | Lead-zinc byproduct; growing copper sector |
Total global silver mine production: approximately 820–870 million troy ounces (25,500–27,000 metric tonnes) per year
The top three countries — Mexico, China, and Peru — together account for approximately 50% of global silver mine production. The top five account for approximately 63%. This is a moderately concentrated supply base, though less extreme than, for example, cocoa (where two countries supply 70%).
Mexico: The Perennial Leader
Mexico has led global silver production for most of the past decade. Its silver production comes from a mix of sources:
- Primary silver mines: Fresnillo plc’s operations (the world’s largest silver mining company by output) are predominantly in Mexico. The Fresnillo mine in Zacatecas state and the Saucito mine together produce over 50 million troy ounces annually.
- Lead-zinc deposits with significant silver: Multiple operations across Chihuahua, Durango, and Sonora states.
Mexico’s silver output is diversified across multiple operations, which provides some resilience against single-site disruptions. However, security issues in some Mexican mining states — including cartel activity that has affected mine operations and mineral theft — represent a persistent operational risk.
China: Scale Through Integration
China’s silver production reflects its massive base metals mining sector. Chinese lead-zinc and copper mines produce silver as an intrinsic byproduct. Because China’s base metals production is enormous in scale, even a modest silver content per tonne of base metals ore generates significant silver volumes.
Chinese silver production is predominantly consumed domestically — China is also the world’s largest industrial user of silver (solar photovoltaic manufacturing, electronics, chemical catalysts) and maintains significant refining capacity.
Peru: South America’s Primary Mining Hub
Peru’s silver comes from two types of operations:
- Large polymetallic mines: The Antamina mine (copper-zinc with silver byproduct) and the Cerro Lindo zinc-copper mine each contribute hundreds of thousands of kilograms of silver annually.
- Primary silver operations: Peru has several dedicated silver mining districts, including in the Ayacucho and Pasco regions.
Peru’s mining sector faces recurring challenges: community opposition to mine projects, regulatory delays, and occasional social conflicts that can interrupt production. The Tia Maria copper-silver project, repeatedly delayed by community opposition, illustrates how Peruvian silver supply is vulnerable to social license issues as much as geological ones.
Key Mines: Where the World’s Silver Actually Comes From
Fresnillo Mine (Mexico)
The Fresnillo mine in Zacatecas, Mexico, operated by Fresnillo plc, is the world’s largest primary silver mine by production volume. It produces approximately 40–50 million troy ounces (Moz) of silver annually, along with gold. The mine has been in operation since 1554 — one of the oldest continuously operating mines in the world.
Fresnillo plc as a company (listed on the London Stock Exchange) operates multiple mines in Mexico including the Saucito mine (another large primary silver operation) and several gold properties. Total Fresnillo plc silver output exceeds 50 Moz annually, making the company responsible for roughly 5–6% of global silver mine supply.
Cannington Mine (Australia)
The Cannington mine in Queensland, Australia, operated by South32 (a BHP spinoff), has been one of the world’s largest silver-lead-zinc mines since its opening in 1997. It produces approximately 10–14 Moz of silver per year alongside lead and zinc. Cannington’s silver occurs in a high-grade silver-lead deposit — the mine is considered a primary silver operation even though lead and zinc are co-products.
Rudna and Polkowice-Sieroszowice (Poland)
KGHM Polska Miedź SA operates the Rudna and Polkowice-Sieroszowice copper mines in Poland’s Legnica-Głogów Copper Belt. These are among Europe’s most significant mining operations and produce approximately 40–45 Moz of silver annually as a copper byproduct. Poland is entirely a silver byproduct producer — all its silver comes from copper ore.
The significance: Poland is the world’s 6th largest silver producer, entirely from copper mining. When KGHM’s copper production is strong, silver output rises; when copper production is disrupted (labour disputes, ore grade issues), silver supply from Poland falls proportionally.
Antamina (Peru)
The Antamina copper-zinc mine in the Andes mountains of Peru — a joint venture among BHP, Glencore, Teck Resources, and Mitsubishi — produces approximately 15–20 Moz of silver annually as a byproduct of copper-zinc production. Antamina has one of the world’s highest silver grades among large-scale copper mines, making its silver output commercially material despite being a byproduct.
Silver Companies With Global Footprint
Beyond individual mines, several companies produce silver across multiple operations:
- Fresnillo plc (UK/Mexico): Largest primary silver producer globally
- Pan American Silver (Canada): Operations in Peru, Mexico, Argentina, Bolivia
- First Majestic Silver (Canada): Mexico operations
- Coeur Mining (USA): Operations across North America
- Polymetal International (Russia): Gold-silver operations in Russia and Kazakhstan
LBMA Silver Price: The Benchmark and How It Works
The global silver price benchmark is the LBMA Silver Price — an electronic auction conducted under the auspices of the London Bullion Market Association (LBMA), administered by ICE Benchmark Administration (IBA).
Auction mechanics:
- One auction per business day at 12:00 PM London time
- Participants submit buy and sell orders in troy ounces, adjusted in incremental rounds until supply equals demand
- The clearing price is published as the LBMA Silver Price in US dollars per troy ounce
- The price is also published simultaneously in British pounds and euros
The LBMA Silver Price replaced the former “London Fix” process (where a small group of banks physically set the price by telephone) after regulatory concerns about manipulation. The electronic auction is more transparent, with more participants and a published audit trail.
Who participates: LBMA Silver Price participants include major bullion banks (HSBC, JP Morgan, the Bank of Nova Scotia), commodity trading firms, and refiners. The participant list has expanded significantly since the move to electronic format.
COMEX Silver Futures: In addition to the LBMA cash price, silver futures trade on the COMEX exchange (part of CME Group) in New York. The COMEX Silver futures contract (ticker: SI) covers 5,000 troy ounces of silver, priced in dollars per troy ounce, with monthly delivery contracts. COMEX is the primary venue for silver futures trading by institutional investors, hedgers, and speculators. The COMEX futures price and the LBMA spot price are closely linked through arbitrage.
Price range context: Silver prices are historically volatile. The price has ranged from approximately $12/oz (2020 low) to $50/oz (1980 Hunt Brothers corner; 2011 near-high) over the past decades, with more recent ranges of $14–30/oz through 2021–2024.
How Country Concentration Affects Supply Risk
Silver’s supply risk profile reflects the byproduct nature of its production.
Political and regulatory risk in Mexico and Peru: Both countries have experienced periods of increased regulatory scrutiny of mining, community opposition to mine projects, and in Mexico’s case, security challenges in mining regions. Mexico’s 2023 revisions to its mining law — including increased royalties and restrictions on open-pit mining in certain zones — created uncertainty for existing and planned silver operations.
China’s domestic consumption: China produces approximately 13% of world silver but also consumes a large proportion domestically (solar panels, electronics manufacturing). Chinese export controls on silver are a potential risk for global supply — if China restricts silver exports (as it has periodically with other materials), the reduction in export volumes affects the international market.
Concentration in single companies: The high concentration of primary silver production in a small number of companies (Fresnillo plc alone represents 5–6% of global supply) creates company-specific risk. Labour disputes, environmental incidents, or permitting problems at Fresnillo’s operations would be immediately visible in global silver supply data.
Base metals price dependency: Because most silver is a byproduct, copper, zinc, and lead prices indirectly determine silver production economics. If copper prices fall sharply and large copper mines reduce output, silver supply falls with it — regardless of where silver prices are. This creates a potential decoupling between silver prices and silver supply responses.
The “invisible” supply risk from byproduct economics: A primary silver mine will continue operating as long as the silver price exceeds the cost of primary silver production. But a copper mine producing silver as a byproduct will continue operating as long as the copper price covers costs — even if silver prices fall to zero. Conversely, if the copper price collapses and large copper mines close, silver supply from those mines disappears even if silver prices are high. This is a supply risk that doesn’t appear in standard silver supply-demand models.
Environmental Considerations: Tailings and Byproduct Mining
The environmental footprint of silver production is largely indistinguishable from the base metals operations that produce most of the world’s silver. The specific issues most relevant to silver supply chains:
Tailings Management
Mining tailings — the waste material left after ore processing — are a major environmental issue across all metal mining. Silver-bearing ores typically contain sulphide minerals that, when exposed to air and water, produce acid mine drainage (AMD) — acidic water containing dissolved heavy metals that can contaminate waterways.
The environmental liability from tailings management is a significant risk factor for mining companies and a concern for communities near mines. Major tailings dam failures (the Samarco disaster in Brazil 2015, the Brumadinho collapse 2019) were copper-iron operations, but the principle applies equally to silver-bearing zinc-lead and copper operations.
Mercury in Artisanal Silver Mining
A portion of global silver is produced by artisanal and small-scale miners (ASM) in countries like Bolivia, Peru, and parts of Africa. Artisanal mining operations frequently use mercury amalgamation to recover silver (and gold) from ore — a method that releases mercury into local environments and creates health hazards for miners and nearby communities. The UN Minamata Convention on Mercury seeks to phase out mercury use in ASM, but enforcement is limited in practice.
Water Use in Arid Mining Regions
Many major silver-producing mines in Chile, Peru, and Mexico operate in extremely arid environments. Water availability is both an operational constraint and a source of conflict with local communities and agricultural users. Water rights disputes have delayed or halted several South American mining projects.
For supply chain professionals with sustainability mandates, the specific mine source of silver — and whether that source meets international tailings management standards, mercury-free processing requirements, and water management criteria — is increasingly relevant as supply chain due diligence requirements (EU CSRD, forthcoming US SEC climate rules) expand.
Silver’s Dual Role: Investment Metal and Industrial Commodity
Silver occupies a unique position in commodity markets as both a precious metal investment and an industrial raw material. This dual role affects how silver supply and demand interact and why silver price movements don’t always correlate neatly with industrial demand.
Industrial demand (~55% of total demand):
- Solar photovoltaics (PV): The fastest-growing industrial silver application. Silver paste is used in solar cell contacts. The IEA’s net-zero scenarios project solar PV capacity multiplying several times, implying massive growth in silver demand. In 2023, solar PV accounted for approximately 14–15% of total silver demand — up from under 5% a decade earlier.
- Electronics: Circuit boards, connectors, semiconductors. Silver’s electrical conductivity (the highest of any element) and thermal conductivity make it irreplaceable in many electronic applications.
- Medical: Antimicrobial applications, wound dressings, medical imaging.
- Chemical catalysts: Silver is a catalyst in ethylene oxide production and several other chemical processes.
Investment demand (~25–30% of total demand):
- Silver coins and bars for retail investors
- Exchange-traded funds (ETFs) backed by physical silver
- Institutional investment
Jewellery and silverware (~10–15%): Traditional end use; affected by fashion cycles and economic conditions.
The solar PV growth trajectory has transformed silver’s demand outlook. In 2023, the Silver Institute estimated that solar PV demand for silver reached approximately 190 million troy ounces — roughly 20% of total mine supply. If solar deployment accelerates as projected, silver demand from this single application could grow substantially, creating structural demand growth that may not be met by proportional supply growth given the byproduct production dynamics described above.
Frequently Asked Questions
Why is silver often cheaper than gold if it’s also a precious metal?
Supply and demand. Gold annual mine production runs approximately 3,500 tonnes; silver mine production runs approximately 25,000–27,000 tonnes — roughly 7–8 times as much silver mined as gold each year. Gold is also accumulated above ground over millennia (most gold ever mined is still in existence as jewellery, bars, or central bank holdings). Silver’s industrial uses consume a large portion of produced silver, reducing the accumulated stock. The Gold/Silver ratio — how many ounces of silver equal one ounce of gold — has historically averaged 50–80:1 and serves as a market analysis tool for relative value.
How does Mexico’s mining policy affect global silver supply?
Mexico’s government has periodically proposed changes to mining regulations — including royalty increases, concession requirements, and environmental permit changes. In 2023, Mexico’s amended mining law increased royalty rates on precious metals. Higher royalties reduce project economics and can deter exploration investment, slowing long-term supply growth. Mexico accounts for approximately 25% of world silver supply, so policy changes there matter to global markets.
What is the relationship between silver and copper prices?
Silver production from copper mines is a byproduct of copper economics. When copper prices are high and copper mines are profitable, silver byproduct production tends to be strong. When copper prices collapse and mines curtail production, silver byproduct supply falls. This means silver supply and copper prices have a loose positive correlation that is independent of the silver price itself.
How is the LBMA Silver Price different from COMEX silver futures?
The LBMA Silver Price is a spot price — the price for immediate delivery of physical silver in London. COMEX silver futures are forward prices for delivery at future dates in New York. The two are linked through arbitrage but differ by the cost of carry (storage, insurance, and financing for the forward period), geographic delivery location differences, and the time frame. For most industrial buyers, the LBMA spot price is the reference; for financial investors and hedgers, COMEX futures are more relevant.
Are silver ETFs a significant part of silver demand?
Yes. Major silver ETFs — particularly iShares Silver Trust (SLV) and Aberdeen Standard Physical Silver Shares ETF — together hold over 500 million troy ounces of physical silver, representing over half a year of global mine production held in vaults. When investors buy ETF shares, the fund buys physical silver, directly impacting market demand. Silver ETF flows are tracked as a real-time indicator of investment demand. A significant net outflow from silver ETFs (investors selling shares, causing the fund to sell silver) can add to supply and pressure prices.
Key Takeaways
- Mexico is the world’s largest silver producer (approximately 25% of global output), followed by China (~13%) and Peru (~12%) — the top three together account for approximately 50% of global silver mine production.
- Approximately 70–75% of global silver supply is a byproduct of copper, zinc, lead, and gold mining — silver supply is therefore largely determined by base metals production economics rather than the silver price itself.
- Key mines include Fresnillo (Mexico) — the world’s largest primary silver mine — Cannington (Australia), and the KGHM copper mines in Poland (Rudna, Polkowice-Sieroszowice).
- The global silver price benchmark is the LBMA Silver Price, auctioned electronically at 12:00 PM London time and published in USD per troy ounce; COMEX silver futures (SI, 5,000 troy ounces) are the primary futures trading vehicle.
- Silver’s byproduct production structure creates an inelastic supply response to price — when silver prices rise, primary mines benefit, but the 70–75% of supply from base metals mines does not increase output in response.
- Solar photovoltaic manufacturing is the fastest-growing source of industrial silver demand — PV accounts for approximately 14–15% of total silver demand (2023) and is projected to grow substantially with solar capacity expansion.
- Tailings management and mercury use in artisanal mining are the primary environmental concerns in silver supply chains; EU CSRD and expanding supply chain due diligence requirements are raising the bar for documentation of mine-level environmental standards.
