A trader sizing the 2026 lead and zinc market has to hold two facts that sound contradictory: demand for both metals is firm — in places still growing — yet the mine supply that feeds it has not kept pace. Refined-zinc consumption is anchored by galvanising (~50–60% of global demand, per ILZSG multi-year averages); refined-lead by batteries (~85%, ILZSG). Meanwhile global zinc mine production sits at roughly 12–13 Mt Zn/yr and lead at ~4.5 Mt Pb/yr (USGS Mineral Commodity Summaries 2026), with several large mines that closed late last decade never fully replaced. The tension between resilient demand and lagging mine supply — not a refined-metal price headline — is the story for 2026, and it shows up first in the concentrate market.
The 40-Second Read: Firm Demand, Tight Concentrate
Zinc and lead demand are structurally firm. Galvanised steel — autos, construction, white goods, infrastructure — drives zinc, and lead-acid batteries (including the 12V auxiliary battery in every electric vehicle) drive lead. Mine supply is the binding constraint: global zinc output of ~12–13 Mt/yr and lead of ~4.5 Mt/yr (USGS MCS 2026) has grown slowly since the late-2010s mine closures, keeping raw-material concentrate tight even when refined metal looks balanced. The single most useful number for a trader is not the LME headline — it is the concentrate treatment charge (TC), which falls when concentrate is scarce.
Zinc: Galvanising Demand Against a Post-Closure Supply Gap
Galvanising accounts for roughly 50–60% of refined-zinc consumption (ILZSG, multi-year average) — a demand base tied to construction and vehicle-body steel rather than to any single fast-moving sector. China is the largest zinc miner at about 33% of global output, followed by Peru, Australia, India, Mexico, the United States, and Bolivia (USGS MCS 2026). That production base has expanded only slowly because the supply side absorbed a series of major closures last decade.
The Century mine (Australia), Lisheen (Ireland), and Skorpion (Namibia) all wound down in the late 2010s, removing meaningful concentrate tonnage that the development pipeline has not replaced at the same pace. The result is a market where refined zinc can read close to balance while concentrate runs tight — the gap that determines smelter economics. Indium, germanium, and cadmium are recovered as by-products at integrated smelters such as Korea Zinc and Nyrstar, so concentrate scarcity ripples into specialty-metal availability as well. For where zinc sits against the other industrial minerals on supply concentration and cycle position, see our five-mineral comparison framework.
Lead: Why EV Growth Doesn't Kill Demand
The most common misread in the lead market is "electric vehicles will shrink lead demand." Lead-acid batteries account for ~85% of refined-lead consumption (ILZSG), and that demand is durable across the transition: every EV still carries a 12V lead-acid auxiliary battery, the internal-combustion fleet is still expanding in emerging markets, and stationary back-up power for data centres and telecom grows with infrastructure build-out. ILZSG projections point to flat-to-modest lead growth, not contraction.
The other structural feature traders cannot ignore is recycling. Secondary (recycled) lead now supplies roughly 55–60% of the global market, drawn almost entirely from used lead-acid batteries (ULAB) processed at secondary smelters under the Basel Convention's transboundary-movement rules. China is the largest primary lead miner at ~40–45%, followed by Australia, Peru, Mexico, the United States, and Russia (USGS MCS 2026). Refined-lead trade also carries a real compliance burden — REACH Substance of Very High Concern listing, Basel Convention controls on ULAB shipments, and country-specific lead-additive and lead-paint bans — that a procurement team must check against the latest revision before contracting. The processing route from galena ore to LME-grade metal is laid out in our five-stage lead and zinc processing guide.
Read the TC, Not Just the LME
Both metals price their refined form on the London Metal Exchange — LME Zinc is Special High Grade at minimum 99.995% Zn, LME Lead at minimum 99.97% Pb — but ore and concentrate are not priced on the LME. Concentrate is priced as LME minus a treatment charge (TC), the fee the smelter earns for converting concentrate to metal. Zinc concentrate TCs are settled annually between major smelters and miners, mirroring the copper TC/RC benchmark mechanism; lead concentrate follows a similar logic.
That makes the TC the cleanest read on the depletion-versus-demand tension. When concentrate is scarce, smelters compete for feed and TCs fall — favourable for the miner, loss-making for the smelter. Zinc concentrate TCs have been volatile enough over recent years to swing across a wide band, which is precisely the signal of a tight raw-material market. Quoting a concentrate "price" as a flat percentage of the LME without naming the assumed TC and payable terms (zinc concentrate is typically ~85% payable with a minimum deduction of 8% Zn units; both lead and zinc concentrates carry payable silver in g/t) misstates cargo value by a wide margin.

Where Non-Traditional Concentrate Fits
Galena and sphalerite almost always occur together in polymetallic sulphide deposits, so a single ore body yields both lead and zinc concentrate with by-product silver — which is why the two markets move together at the mine and split only at the smelter. Bare Syndicate's lead-ore portfolio runs High Grade Galena at 60–70% Pb for battery manufacturing and refining, and a standard grade at 40–55% Pb; the zinc-ore line covers sulphide concentrate at 15–20% Zn with iron below 8% for smelter and galvanising feed, plus oxide material at 15–30% Zn for hydrometallurgical routes. In our Karachi warehouse operations, lead-zinc cargoes are assayed for the Pb/Zn split and the silver payable before shipment, because those two figures, not the headline grade, set the contract value.
Emerging-region sulphide deposits — Pakistan's Duddar zinc-lead body and the broader Lasbela–Khuzdar belt among them — are increasingly part of the non-traditional supply picture, but their bankability turns on infrastructure, financing, and counterparty alignment rather than geology alone. We do not publish reserve figures for any Pakistani deposit without a Geological Survey of Pakistan or PMDC source; for the project-economics detail and the deposit map, see our analysis of lead and zinc in developing countries. One technical point that governs sourcing: sulphide ores (sphalerite, galena) are processed by differential flotation, while oxide ores (smithsonite, cerussite) require a leach route — they are not interchangeable feedstocks at any price.
What NOT to Do
- Don't assume EVs shrink lead or zinc demand. The 12V auxiliary battery is still lead-acid, galvanised sheet is still used in EV bodies, and ILZSG projects flat-to-modest growth, not contraction.
- Don't say "lead ore" or "zinc ore is priced on the LME." The LME contracts are for refined metal (SHG zinc 99.995%, lead 99.97%). Concentrate is priced as LME minus TC.
- Don't conflate sulphide and oxide ores. Sphalerite/galena go through flotation; smithsonite/cerussite need a leach route. The processing economics differ entirely.
- Don't quote a concentrate price as a flat percentage of the LME without naming the TC and payable terms (zinc ~85% payable, 8% Zn-unit deduction; payable silver in g/t).
- Don't treat secondary lead as a niche. Recycled lead is ~55–60% of global supply and a structural feature of the market, governed by the Basel Convention.
- Don't cite Duddar or any Pakistani deposit's reserves without a Geological Survey of Pakistan or PMDC source. Geology is not bankability.

Additional Market Context
The foundational data sources for lead and zinc are the USGS Mineral Commodity Summaries (annual lead and zinc chapters, January release) for production and reserves, and the International Lead and Zinc Study Group (ILZSG) monthly bulletin for mine, refinery, and consumption balances. The LME publishes daily cash and three-month settlements for refined lead and zinc; SHFE covers the China domestic market. For demand-side context, the International Zinc Association tracks galvanising end-use, the Battery Council International tracks lead-acid battery demand, and the Galvanizers Association covers continuous-sheet versus batch hot-dip galvanising. The Basel Convention governs the transboundary movement of used lead-acid batteries that feed secondary smelters.
For traders running a multi-metal book, lead and zinc reward watching the concentrate balance and the annual TC settlement as leading indicators, ahead of the refined-metal price. The annual benchmark negotiation and the monthly ILZSG balance together tell you whether the depletion-versus-demand tension is tightening or easing in any given quarter.
