Zinc Price Forecast 2026: Mine Closures, Treatment Charges, and Supply Tightness

> Key Takeaway: Zinc is the forgotten base metal. Major mine closures have removed significant production capacity since 2015, treatment charges are compressing toward multi-year lows, and the development pipeline of 309 tracked projects is heavily skewed toward early-stage exploration. The structural setup for zinc heading into 2026 is tighter than most investors appreciate.

Quick Summary

• Mining Terminal tracks 309 zinc projects globally, but only 31 sit in the development stage and 67 are in production, limiting near-term supply flexibility.
• A wave of large mine closures and depletions (Century, Lisheen, Brunswick, Skorpion) removed over 1 million tonnes per year of capacity since 2013, and replacement projects have not kept pace.
• Spot treatment charges for zinc concentrates have declined sharply, signaling tightness in concentrate availability that historically precedes price rallies.
• Galvanizing accounts for roughly 60% of global zinc consumption, tying demand directly to steel production, infrastructure spending, and emerging-market construction.

Zinc project pipeline: what 309 projects actually tells you

Mining Terminal tracks 309 zinc projects across 40+ jurisdictions. That is 2.6% of the total project database, placing zinc well behind gold (5,043), copper (2,066), and lithium (696) in pipeline depth. The narrower pipeline matters because it limits the industry's ability to respond to supply shortfalls with new production.

Canada dominates the zinc pipeline with 108 projects (35%), followed by Australia at 58 projects (18.8%). Peru, the USA, and Kazakhstan round out the top five. Ireland, historically a major zinc province (Tara, Lisheen), still hosts 13 tracked projects despite Lisheen's closure in 2015.

| Country | Projects | Share |
| --- | --- | --- |
| Canada | 108 | 35.0% |
| Australia | 58 | 18.8% |
| Peru | 23 | 7.4% |
| USA | 18 | 5.8% |
| Kazakhstan | 15 | 4.9% |
| Ireland | 13 | 4.2% |
| Mexico | 12 | 3.9% |
| India | 9 | 2.9% |
| Other | 53 | 17.2% |

The top three jurisdictions account for 61.2% of the pipeline. That concentration means permitting or policy shifts in Canada, Australia, or Peru can ripple across the entire zinc supply outlook.

Mine depletion pressure: the closures that reshaped supply

Any credible zinc price forecast 2026 must start with what has already left the market. Since 2013, several of the world's largest zinc mines have closed, exhausted reserves, or entered care and maintenance. The cumulative impact has been severe:

• Century Mine (Australia): Closed in 2015 after producing ~500,000 tonnes per year at peak. Was the world's second-largest zinc mine. Tailings retreatment operations produce a fraction of the original output.
• Lisheen (Ireland): Closed in 2015. Produced approximately 160,000 tonnes per year. No replacement project has been built in the Irish zinc belt at comparable scale.
• Brunswick Mine (Canada): Closed in 2013. Was a cornerstone of New Brunswick's zinc-lead output at roughly 200,000 tonnes of zinc per year.
• Skorpion Zinc (Namibia): Placed on care and maintenance in 2020 after reserve depletion. Produced approximately 90,000 tonnes of refined zinc per year.

Combined, these closures removed well over 900,000 tonnes per year of zinc mine capacity. Meanwhile, new mine commissioning has been limited. Vedanta's Gamsberg in South Africa ramped up in 2019-2020, but its nameplate capacity of 250,000 tonnes per year has not fully offset the aggregate losses. China's small-mine sector has added incremental tonnage, but output is fragmented, higher-cost, and increasingly constrained by environmental enforcement.

The effect: a global zinc mine supply base that is older, more concentrated in fewer large operations, and more vulnerable to disruption than at any point in the last decade.

Treatment charges as a leading signal

Treatment charges (TCs) are the fees that zinc miners pay smelters to process concentrate into refined metal. TCs are one of the most reliable forward indicators of concentrate market balance, and by extension, zinc price direction.

The dynamic works as follows:

• High TCs indicate smelters have ample concentrate supply and bargaining power. This typically coincides with looser zinc markets and softer prices.
• Low TCs indicate concentrate is scarce, miners have leverage, and smelters must compete for feedstock. This typically precedes price strength.

Benchmark annual TCs for zinc concentrates declined from above $270 per tonne in 2017 to $165 per tonne in 2024, and spot TCs moved sharply lower through 2025 into early 2026. The direction is clear: concentrate availability is tightening.

The TC compression reflects the closure wave described above, combined with limited new mine supply and steady smelter demand. Chinese smelters, which process roughly half the world's zinc concentrate, have reported feedstock procurement challenges, with some reducing utilization rates rather than paying elevated spot prices for scarce concentrate.

When screening stocks, falling TCs serve as an early-warning system. When TCs decline below cash-cost thresholds for marginal smelters, the market is telling you that mine supply is not keeping up. That signal has preceded zinc price rallies in 2006-2007, 2016-2017, and may be doing so again now.

Demand structure: galvanizing, infrastructure, and emerging markets

Zinc demand is heavily tied to steel and construction through a relatively concentrated end-use structure:

• Galvanizing: Approximately 60% of global zinc consumption. Hot-dip galvanizing protects steel from corrosion and is essential for construction, automotive, and infrastructure applications.
• Die-casting and alloys: Roughly 15% of demand. Used in automotive parts, hardware, and precision components.
• Brass and bronze: Around 10%. Plumbing, electrical connectors, and decorative applications.
• Other: Zinc oxide (rubber, chemicals), rolled zinc (roofing, batteries), and miscellaneous industrial uses.

The galvanizing concentration means that zinc demand is fundamentally a steel demand derivative. Global crude steel production has been running above 1.8 billion tonnes per year, with China representing roughly 54% of output. While Chinese steel output has been roughly flat since 2020, the rest of the world has been growing, and infrastructure stimulus programs across the US, Europe, India, and Southeast Asia are creating incremental demand pull.

India is particularly important to the zinc demand outlook. Indian steel production has been expanding at 6-8% annually, supported by government infrastructure spending (roads, railways, housing). India's per-capita zinc consumption remains well below developed-market levels, suggesting structural catch-up potential. Vedanta's Hindustan Zinc, the country's dominant producer, has been expanding capacity in response.

On the risk side, a severe downturn in Chinese property construction could soften galvanizing demand materially. However, the policy direction in China has shifted toward infrastructure (power grid, renewable energy installations) rather than residential construction, which could partially offset property weakness.

Stage-weighted supply: the pipeline is exploration-heavy

Raw project counts can be misleading. A more useful zinc price forecast 2026 framework weights the pipeline by stage, because a grassroots exploration project contributes nothing to near-term supply. Here is the stage distribution for the 309 tracked zinc projects:

| Stage | Projects | Share |
| --- | --- | --- |
| Exploration | 200 | 64.7% |
| Development | 31 | 10.0% |
| Production | 67 | 21.7% |
| Suspended | 11 | 3.6% |

Nearly two-thirds of the zinc pipeline is exploration-stage. These projects are 5-15 years from production under favorable conditions, and many will never reach production at all. The development bucket of 31 projects is the critical filter for near-term supply additions. Even within that bucket, not all projects have secured financing, permits, or offtake agreements.

The 67 producing operations are the current supply base. As discussed above, several of these are mature operations approaching end-of-life, which means the production count is likely to shrink before it grows unless development projects are advanced.

The 11 suspended projects represent potential swing supply that could restart if zinc prices rise enough to justify the capital expenditure. However, restart timelines are typically 12-24 months and require both price confidence and capital access.

This stage-weighted view supports the structural tightness thesis. Even if zinc prices rise sharply, the pipeline cannot deliver material new supply for several years. For more on how stage mix affects supply response, see mining project stages 2026 and feasibility study stages explained.

Three scenarios for the zinc price forecast 2026

No single-point forecast is useful in a market driven by cyclical demand and lumpy supply disruptions. The following scenario framework provides a range of outcomes with the conditions that would need to hold for each.

| Scenario | Price range (USD/tonne) | LME equivalent (USD/lb) | Key conditions |
| --- | --- | --- | --- |
| Bear | $2,200 - $2,500 | $1.00 - $1.13 | Global recession, severe demand destruction in steel and construction, Chinese property crisis deepens, smelter shutdowns reduce concentrate demand |
| Base | $2,700 - $3,100 | $1.22 - $1.41 | Mine closures offset by some new supply (Gamsberg ramp, Chinese incremental output), stable industrial demand, TCs remain compressed but manageable |
| Bull | $3,300 - $3,800 | $1.50 - $1.72 | Accelerated mine depletion, supply crunch from delayed development projects, infrastructure spending boom in India and the US, smelter competition for scarce concentrate drives prices higher |

The base case reflects a market in mild structural deficit where closures and depletions offset incremental supply additions. The bear case requires a meaningful demand shock, which is always possible in a cyclical metal but runs counter to the current infrastructure spending trajectory. The bull case requires the concentrate tightness signaled by falling TCs to fully translate into refined metal scarcity, which historically takes 6-18 months to play out.

Zinc prices traded in the $2,400-$2,800 per tonne range for much of 2025. A move toward the upper end of the base case or into the bull scenario would likely require visible inventory drawdowns on the LME and Shanghai Futures Exchange, combined with further TC compression.

Equity positioning: how to express the zinc thesis

Zinc equities are not a deep market. Most pure-play zinc miners are small to mid-cap, and many of the largest zinc producers are diversified companies (Glencore, Teck, Boliden) where zinc is one revenue stream among several.

On the equity side, looking to build zinc exposure, the key considerations are:

• Pure-play sensitivity: Smaller producers and developers with high zinc revenue concentration will move more with zinc prices. See zinc mining stocks and best zinc mining stocks for screened lists.
• Diversified producers: Large-cap names like Glencore offer zinc exposure with lower single-commodity risk but also lower torque to zinc price upside.
• Developer optionality: Development-stage zinc projects can offer asymmetric upside if zinc prices rise enough to justify financing and construction. However, these carry execution, permitting, and dilution risk.
• Jurisdiction selection: Zinc projects in stable mining jurisdictions (Canada, Australia, Ireland) typically command higher valuation multiples than those in higher-risk geographies. Use the mining jurisdiction checklist to evaluate.

Monitoring framework: what to watch in 2026

A zinc price forecast 2026 should be updated as data changes, not published once and forgotten. The following indicators should be tracked on a regular cadence:

• Spot and benchmark treatment charges: The single most important leading indicator. Track the Fastmarkets and Asian Metal benchmark TCs for zinc concentrates. Sustained declines below $150/tonne would strongly support the bull case.
• LME and SHFE zinc inventories: Exchange-monitored warehouse stocks provide a real-time read on physical market balance. LME zinc inventories below 100,000 tonnes historically correlate with price strength.
• Chinese smelter utilization rates: If Chinese zinc smelters reduce output due to concentrate scarcity or environmental restrictions, the refined metal market tightens faster than mine supply data alone would suggest.
• New project milestones: Track permitting approvals, feasibility study completions, and construction decisions for the 31 development-stage zinc projects. Any material delays extend the supply deficit timeline.
• Indian steel production data: Monthly crude steel output from India's Ministry of Steel serves as a proxy for incremental zinc demand growth in the fastest-growing major market.
• Global PMI and construction data: Zinc is a cyclical metal. Manufacturing PMIs and construction spending data from China, the US, and Europe provide the demand context for any price forecast.

FAQ

What is the zinc price forecast for 2026?

The zinc price forecast 2026 depends on the balance between ongoing mine depletion and new supply additions. A base-case estimate is $2,700-$3,100 per tonne, reflecting structural tightness from major mine closures offset by incremental supply from existing ramp-ups. A bull case of $3,300-$3,800 per tonne is plausible if concentrate shortages intensify and infrastructure demand accelerates.

Why are zinc treatment charges important for price forecasting?

Treatment charges reflect the bargaining power between miners and smelters. When TCs decline, it signals that zinc concentrate is scarce, which means mine supply is not keeping pace with smelter demand. Historically, sustained TC declines have preceded zinc price rallies by 6-18 months because smelters eventually pass feedstock costs through to refined metal markets.

How many zinc mines have closed in recent years?

Several of the world's largest zinc mines closed between 2013 and 2020, including Century (Australia, ~500Kt/yr), Lisheen (Ireland, ~160Kt/yr), Brunswick (Canada, ~200Kt/yr), and Skorpion (Namibia, ~90Kt/yr). Together, these closures removed over 900,000 tonnes per year of capacity. Replacement supply from new mines has been insufficient to fully offset these losses.

What drives zinc demand?

Galvanizing steel accounts for approximately 60% of global zinc consumption. This ties zinc demand directly to steel production, construction activity, and infrastructure spending. India is the fastest-growing zinc demand market due to rapid urbanization and government infrastructure programs. Die-casting, brass production, and zinc oxide applications make up the remaining 40%.

How can investors get exposure to zinc prices?

Investors can gain zinc exposure through zinc mining stocks, diversified base metal producers, or physically-backed zinc ETFs. Pure-play zinc miners offer higher price sensitivity but typically carry greater execution and liquidity risk. Diversified producers like Glencore provide lower-volatility exposure. Development-stage projects offer asymmetric optionality but require careful evaluation of permitting, financing, and technical risk. See mining stock valuation methods for a structured approach.

Bottom Line

The zinc price forecast 2026 is fundamentally a supply replacement story. Major mine closures have structurally reduced available capacity, the development pipeline is exploration-heavy with few shovel-ready projects, and treatment charges are signaling concentrate tightness. On the demand side, galvanizing-driven consumption remains tied to global steel and infrastructure cycles, with India providing a structural growth anchor.

The base case points to prices in the $2,700-$3,100 per tonne range, with meaningful upside risk if supply crunch dynamics accelerate. Investors should monitor treatment charges, LME inventories, and Chinese smelter utilization as the highest-signal data points through 2026. Position accordingly, but size for the cyclical volatility that zinc has historically delivered.
