Key Facts
- Nexa Resources shares closed flat ending the New York session at US$12.85 as investors weighed the zinc miner’s direct exposure to galvanised-steel demand.
- Buenaventura edged up 0.63 per cent with its New York-listed shares settling at US$30.47, lifted by the firm’s broader precious- and base-metals portfolio.
- Peru remains the world’s second-largest zinc producer with output concentrated in the central Andes where Buenaventura and Nexa both operate significant polymetallic mines.
- Galvanised steel consumes over half of global refined zinc linking the metal’s fortunes directly to construction, infrastructure spending and automotive manufacturing cycles.
- Mexico and Bolivia are top-10 zinc producers supplying concentrates to regional smelters and making Latin America a critical swing region for global zinc feedstock.
- Investors use Nexa as a pure-play zinc proxy because its Brazilian smelters and Peruvian mines tie earnings tightly to refined zinc prices and treatment charges.
Today’s Focus
Latin America’s two most-watched zinc equities painted a subdued picture on Monday. Nexa Resources, the integrated miner-smelter with operations in Brazil and Peru, saw its New York shares hold perfectly flat at US$12.85. Buenaventura, the Peruvian polymetallic producer, inched higher by 0.63 per cent to US$30.47, reflecting its more diversified revenue mix that includes gold and silver alongside zinc concentrates.
The muted moves came as global zinc markets grapple with a tug-of-war. On one side, construction activity—the dominant end-user of galvanised steel—faces headwinds from elevated interest rates in major economies, softening near-term demand for the rust-proofing metal. On the other, tight mine supply from Peru, Bolivia and Mexico, where output has been constrained by ore-grade declines and regulatory delays, is keeping concentrate markets snug.
For foreign investors watching Latin America, the two names offer distinct exposures. Nexa, with its own smelters in Brazil, captures the full value chain from Andean ore to finished galvanising alloys sold to steelmakers. Buenaventura, by contrast, is a purer play on Peruvian geology and politics, with zinc revenues arriving through concentrate sales from wholly-owned and joint-venture mines in the high Andes.
The regional demand story hinges on Brazilian construction. As Latin America’s largest economy, Brazil consumes galvanised steel for roofing, structural frames and logistics warehouses—all of which feed back into orders for Nexa’s refined zinc. A stalled infrastructure pipeline or slower housing starts there would ripple through the entire zinc complex.
What matters today. The flat-to-mixed session for Latin American zinc proxies reflects a market that has priced in ample short-term supply but remains nervous about mine-side tightness in Peru and Mexico as construction demand waits for a rate-cut catalyst.

01 The session in one read
Latin American zinc-linked equities delivered a split decision on Monday. Nexa Resources, the integrated zinc miner and smelter with assets in Brazil and Peru, closed unchanged at US$12.85 as investors digested a market caught between soft construction demand and constrained mine supply.
Buenaventura, Peru’s diversified precious- and base-metals producer, rose 0.63 per cent to US$30.47, supported by the firm’s gold and silver exposure rather than any zinc-specific catalyst. The duo’s divergence captures the broader zinc market’s indecision: ample refined inventories weigh on sentiment, yet Latin American concentrate supply remains tight enough to prevent a sharper sell-off.
Assessment — Mine tightness battles construction doubts MEDIUM
Zinc is stuck between two narratives that neither Nexa’s flat close nor Buenaventura’s fractional gain could resolve. Concentrate supply from Latin America remains constrained by declining ore grades at ageing Peruvian mines and Bolivia’s persistent logistical bottlenecks, which should support prices. But the demand side—galvanised steel for buildings, bridges and cars—is waiting on central banks to lower borrowing costs before construction activity accelerates. Until that catalyst arrives, zinc-exposed equities are likely to drift, with occasional spikes driven by mine-disruption headlines rather than a sustained demand-led rally. The variable to watch is any change in Brazilian construction PMIs, which signal downstream appetite for the galvanised steel that Nexa’s smelters supply.
02 The board
With Nexa Resources unmoved at US$12.85 and Buenaventura ticking up to US$30.47, the session offered little directional signal for zinc bulls or bears. Nexa’s flat performance underscores investor caution towards a pure-play name whose smelting margins depend directly on refined zinc prices and Brazilian steel-mill demand for galvanising alloys.
Buenaventura’s modest 0.63 per cent gain reflects the cushion provided by precious metals within its portfolio—gold and silver revenues soften the blow when base-metal prices stall. For foreign investors, the two names together paint a picture of a regional zinc sector in wait-and-see mode, with neither mine-side tightness nor construction demand exerting decisive pull.

The session read
The Ibovespa was little changed 0.00%, with breadth negative — 1 of 4 names higher. IPSA led, while MERVAL lagged.
03 What moved it
Zinc’s muted moves trace back to its core industrial role. More than half of the world’s refined zinc becomes a rust-proof coating for steel—galvanised beams, roofing sheets, highway guardrails and transmission towers all rely on it. When global construction and infrastructure spending slow, as they have under elevated interest rates, zinc demand softens and prices drift.
On the supply side, Latin America remains a critical swing producer. Peru, the world’s second-largest zinc miner, sends concentrates from high-Andean polymetallic mines to smelters across Asia and North America. Mexico and Bolivia, both top-10 producers, add further concentrate tonnage. Output from all three has been constrained by ore-grade declines, community disputes and regulatory inertia, keeping the feedstock market tight even as refined demand wobbles.
04 The Latin American read
For anyone tracking zinc through a Latin American lens, the two listed names offer markedly different exposures. Nexa Resources is the region’s only large-cap integrated zinc miner-smelter: its Brazilian plants turn Peruvian and Brazilian concentrates into refined metal and galvanising alloys, linking its shares directly to both the London Metal Exchange zinc price and local construction activity.
Buenaventura functions as a broader Peruvian mining proxy. Its zinc output comes from wholly-owned polymetallic mines and joint ventures with global majors, producing concentrates rather than refined metal. The company’s share price therefore responds more to Peruvian geology, export logistics and mining regulation than to downstream galvanising demand—gold and silver prices often matter more on any given day.
05 The names to watch
Nexa Resources is the region’s closest equivalent to a zinc pure-play. Its Brazilian smelters—among the largest in Latin America—supply steelmakers who produce galvanised sheet for construction and consumer goods, meaning Brazilian infrastructure budgets and housing starts feed directly into the company’s order book.
Buenaventura’s zinc exposure comes embedded in a diversified portfolio. Its stake in the El Brocal mine and other polymetallic assets delivers zinc concentrates alongside copper, lead and precious metals, making it a barometer for Peruvian mine production rather than a direct bet on refined zinc premia. Both names, however, are the standard entry points for international capital seeking Latin American zinc exposure.
06 The outlook
Zinc’s near-term trajectory depends on whether construction demand revives before mine supply loosens. Latin American producers hold a key card: Peruvian, Bolivian and Mexican concentrates represent an irreplaceable feedstock source for global smelters, and any disruption—a strike, a landslide, a permitting delay—could tighten the refined market quickly.
On the demand side, Brazilian construction remains the regional bellwether. A pipeline of logistics warehouses, urban housing and transport infrastructure all require galvanised steel, creating a direct link between São Paulo building permits and Nexa’s smelter run-rates. Until borrowing costs fall and construction activity picks up, zinc-exposed equities will likely trade sideways, punctuated by supply-scare rallies that lift both Nexa and Buenaventura in tandem.
07 What to watch
- Brazilian construction PMI: A leading indicator of galvanised-steel demand from Latin America’s largest economy; a sustained uptick would signal rising zinc orders for Nexa’s smelters.
- Peruvian mine supply: Any strike, landslide or permitting delay in the central Andes could tighten global zinc concentrate markets and lift both Buenaventura and Nexa shares.
- Mexican and Bolivian concentrate exports: Together with Peru, these two top-10 producers form Latin America’s feedstock hub; logistical or regulatory disruptions there ripple through global zinc prices.
- LME zinc warehouse inventories: Rising stocks signal ample refined supply and cap price upside; draws would confirm that tightness in the concentrate market is spilling into refined metal.
