Zinc Slips as Nexa Falls 3.2%; LatAm Producers Drop
Key Facts
- Nexa Resources closed at US$11.80 in New York, a decline of 3.20% for the session. The Peru and Brazil-focused zinc producer led the regional complex lower on Thursday, October 1, 2026.
- Buenaventura finished at US$31.49, easing 0.28% on the day. The Peruvian precious and base metals miner held up better than Nexa but still tracked the weaker industrial tone.
- Official three-month zinc fell 0.75% to US$3,842 a tonne on Wednesday, September 30, 2026. Cash settlement dropped 0.58% to US$3,954, framing the two-day drift into Thursday’s session.
- Peru’s zinc concentrate output fell 12% year on year to 746,000 tonnes in January–July 2026. July production alone dropped 11.1% to 102,100 tonnes, tightening regional physical supply.
- Galvanised steel is zinc’s main end-use, linking demand to construction and infrastructure. Softer Chinese construction activity limited buying appetite despite the tighter Latin American supply picture.
- Nexa operates zinc mines and smelters in both Peru and Brazil. That direct operational leverage makes its New York-listed shares the sharpest regional proxy for zinc price moves.
Today’s Focus
Zinc-linked equities drifted lower on Thursday, October 1, 2026, as soft construction demand outweighed a tightening supply story from Peru. Nexa Resources, the most direct regional zinc proxy, fell 3.20% to US$11.80 in New York. Buenaventura slipped a milder 0.28% to US$31.49.
The decline extended a move that began midweek, when the official three-month zinc price dropped 0.75% to US$3,842 a tonne and cash settlement eased 0.58% to US$3,954 on Wednesday, September 30, 2026.
Peru’s zinc concentrate production fell 12% year on year to 746,000 tonnes in the first seven months of 2026, a genuinely supportive supply factor. But softer Chinese construction demand for galvanised steel, zinc’s main market, kept buyers cautious.
For foreigners watching Latin America, the session showed how even a region with clear supply constraints can trade lower when the demand side falters. Nexa’s sharper drop reflects its direct zinc smelting and mining exposure in Peru and Brazil.
What matters today. The trade is tension between falling Peruvian supply and uncertain construction-led demand from China, and Thursday showed demand worries winning.
01 The session in one read
Latin America’s two main listed zinc proxies both closed lower on Thursday, October 1, 2026, but with very different magnitudes.
Nexa Resources, which runs zinc mines and smelters in Peru and Brazil, dropped 3.20% to end New York trading at US$11.80.
Buenaventura, the Peruvian miner with a broader precious and base metals mix, slipped just 0.28% to US$31.49.
The moves suggest investors were focusing on direct zinc exposure and soft demand signals rather than a uniform regional mining sell-off.
Zinc proxies opened October on a soft note as the market prioritised softer Chinese construction activity over Peru’s 12% year-on-year drop in January–July concentrate output. Nexa’s 3.20% fall to US$11.80 stood out against Buenaventura’s 0.28% dip to US$31.49, suggesting investors were pricing direct zinc operating leverage rather than a broad regional sell-off. The variable to watch is any fresh Chinese infrastructure or property stimulus signal, which would test whether galvanised steel demand can absorb a market already tightening at the mine level.
02 The board
Thursday’s New York closes showed the zinc complex under clear but not uniform pressure. Nexa Resources tumbled 3.20% to US$11.80, the weakest reading among the two regional proxies and a signal that direct zinc operating leverage was being repriced.
Buenaventura held far closer to flat, finishing down only 0.28% at US$31.49, cushioned by its diversified book of precious and base metals beyond zinc alone.

03 What moved it
Zinc’s single biggest end-use is galvanised steel, the zinc-coated metal used in construction and infrastructure, and reports of softer Chinese construction activity kept buyers on the sidelines.
That demand caution overshadowed a genuinely supportive supply story from Peru, the world’s second-largest zinc concentrate producer.
Peruvian zinc concentrate output fell 12% year on year to 746,000 tonnes in the January–July 2026 period, with July alone down 11.1% to 102,100 tonnes.
The two-day drift was already visible in the official three-month zinc price, which fell 0.75% to US$3,842 a tonne on Wednesday, September 30, while cash settlement eased 0.58% to US$3,954.
04 The Latin American read
For investors watching the region from abroad, Peru, Bolivia and Mexico remain the anchor zinc producers, with Peru the most liquid way to express a view.
Nexa Resources is the purest listed play: it operates zinc mines and smelters across both Peru and Brazil, meaning its share price tends to move with zinc fundamentals more than diversified miners.
Buenaventura offers a softer-touch proxy, since zinc is one part of a precious and base metals portfolio that includes significant gold and silver output.
The gap between Thursday’s moves illustrates that distinction: Nexa bore the full force of the zinc demand worry, while Buenaventura absorbed it far more mildly.
05 The names to watch
Nexa Resources is the direct regional zinc bellwether because its mines and smelters in Peru and Brazil give shareholders operational exposure through the full zinc production chain.
Buenaventura matters as a secondary proxy, particularly for investors who want Peruvian mining exposure but prefer a diversified precious and base metals portfolio.
Both names have now shown two very different beta profiles to the same zinc demand signal, a useful distinction for anyone building a Latin American metals book.
06 The outlook
The market is caught between a clear supply tightness in Peruvian concentrate and a demand outlook that depends heavily on Chinese construction.
If Beijing delivers fresh infrastructure or property stimulus, galvanised steel demand could strengthen and reward the regional zinc complex; if not, tighter Peruvian supply may only prevent deeper falls rather than spark a rally.
07 What to watch
- Chinese construction data: Watch for any infrastructure or property stimulus signal that could revive galvanised steel demand, zinc’s main end-use.
- Peruvian production trends: Monthly zinc concentrate output from Peru will show whether the 12% January–July decline is stabilising or deepening.
- Nexa share moves: As the purest regional zinc proxy, Nexa’s reaction will signal whether investors are pricing supply tightness or demand weakness.
- Buenaventura divergence: The Peruvian miner’s mild drop of 0.28% shows how diversified metals exposure can cushion zinc-specific shocks.
Frequently Asked Questions
Why did Nexa Resources fall more than Buenaventura?
Nexa has direct zinc mining and smelting exposure in Peru and Brazil, so its shares carry more zinc-specific operating leverage than Buenaventura’s diversified precious and base metals portfolio.
What is galvanised steel and why does it matter for zinc?
Galvanised steel is steel coated with zinc to prevent rust, and construction and infrastructure are its main markets, making Chinese building activity a key zinc demand driver.
Is zinc supply tightening in Latin America?
Yes. Peru’s zinc concentrate output fell 12% year on year in January–July 2026 to 746,000 tonnes, with July alone down 11.1% to 102,100 tonnes.
Which Latin American countries are major zinc producers?
Peru, Bolivia and Mexico are the region’s major zinc producers, with Peru the most followed by international investors in listed mining equities.
