Today’s Focus
Zinc proxies advanced on Tuesday, October 27, with Nexa Resources gaining 2.66% to US$11.95 and Buenaventura rising 1.04% to US$28.73. Both are US-listed miners with Latin American zinc exposure.
China’s industrial profits rose 15.5% in the first nine months of 2026 from a year earlier, a little slower than the 15.7% of the first eight months, according to the RT economic calendar. Zinc is used to galvanise steel, so industrial demand matters for the metal.
Wall Street also rose, with the S&P 500 up 0.60%, which helped miners across the board.
For Latin America, Peru, Bolivia and Mexico are significant zinc mine suppliers, and Nexa runs smelters in Brazil.
What matters today. Zinc miners gained with the market, but with no live zinc price in our data, the shares are the signal.
01 The session in one read
Zinc’s regional proxies closed higher on Tuesday, October 27, with Nexa Resources up 2.66% at US$11.95 and Buenaventura up 1.04% at US$28.73.
Nexa is the more direct zinc play. Buenaventura’s shares also reflect gold and silver, which rose on the day, so its move says less about zinc.
Zinc miners rose with the market, and the move says more about risk appetite than about a change in the zinc market. The next test is the US Federal Reserve decision on Wednesday.
02 The board
Nexa Resources, the most direct listed proxy for regional zinc because it mines and smelts in Peru and Brazil, led the move with a 2.66% rise to US$11.95. Buenaventura, which offers broader Peruvian polymetallic exposure, advanced 1.04% to US$28.73.
Both names traded higher on a day when gold and silver funds also rose, so part of the move reflects precious metals rather than zinc alone.

03 What moved it
A broad risk-on session lifted miners. The S&P 500 gained 0.60% and the Nasdaq 1.18%, and China’s industrial profits stayed solid.
Zinc is used mostly to coat steel against rust, so it follows construction, infrastructure and vehicle demand, which in turn track China’s industrial health.
Brazil’s real recovered about 1% against the dollar, which matters for Nexa’s Brazilian smelting costs.
04 The Latin American read
Peru, Bolivia and Mexico are central to world zinc mine supply, and Peru is one of the world’s largest zinc miners.
For investors watching the region, higher zinc prices help miners’ revenue but raise pressure on power-hungry smelters. Nexa’s Brazilian smelting exposure makes the company sensitive to both metal prices and electricity costs.
05 The names to watch
Nexa Resources is the most direct regional listed proxy for zinc, with mining and smelting operations in Peru and Brazil. Its New York shares registered the cleanest signal on Tuesday, gaining 2.66% to US$11.95.
Buenaventura offers exposure through zinc-bearing polymetallic assets in Peru, but its stock also reflects gold and silver. That explains the smaller 1.04% advance to US$28.73.
06 The outlook
The rally’s durability depends on global risk appetite and Chinese industrial demand. The US Federal Reserve decision on Wednesday is the next test for miners.
07 What to watch
- US Federal Reserve decision: The Fed announces its rate decision on Wednesday, which can move the dollar and metals.
- Chinese industrial data: Further strength in profits would support industrial metals such as zinc.
- Gold and silver prices: They drive Buenaventura’s shares as much as zinc does.
- Nexa Resources share direction: As the most direct listed regional proxy, its reaction will show whether investors see strength lasting.

Which Latin American countries matter for zinc mine supply?
Peru, Bolivia and Mexico are key zinc mine suppliers, and Peru is one of the world’s largest zinc miners.
What links zinc to construction and infrastructure?
A large share of global zinc goes into galvanising, which coats steel to prevent rust, tying the metal to construction, infrastructure and vehicle production.
Why did Buenaventura rise less than Nexa?
Buenaventura’s stock also reflects gold and silver because zinc is only one part of its Peruvian polymetallic portfolio, while Nexa is a more direct zinc proxy.
