Today’s Focus
Zinc stocks split on Wednesday. Teck Resources gained 1.22% to US$63.04, while Nexa Resources, the main Latin American zinc producer listed in New York, fell 1.09% to US$11.82.
Zinc is used mainly to galvanise steel, which protects it from rust, so the metal follows construction and car production. Peru is among the world’s largest producers, behind China.
There was no zinc-specific data on the economic calendar for 28 October.
What matters today. Zinc is a quiet but important Latin American export, and Peru’s economy and mining towns depend on it, so a steady price supports local budgets and jobs.
01 The session in one read
Nexa Resources closed at US$11.82, down 1.09% from US$11.95. Teck closed at US$63.04, up 1.22% from US$62.28.
Copper-linked miners also moved. Freeport-McMoRan rose 0.99% and Southern Copper, which produces zinc as a by-product, slipped 0.27%.
The mixed result suggests a company-by-company day, not a clear call on the metal.
The two zinc names moved in opposite directions, and we have no verified zinc price to explain either. That makes the signal weak.
The variable to watch is the zinc price itself and whether Chinese and US demand data confirm the construction picture.
02 The board
Nexa is the cleanest US-listed Latin American zinc proxy. Its mines are in Peru and Brazil.
Teck is a diversified Canadian miner with zinc and copper. Its gain shows the sector was not weak across the board.

03 What moved it
Without a zinc price, the best guide is the macro backdrop. The US Federal Reserve, the US central bank, held rates at 3¾% to 4%, two voters preferred a rise, and the dollar index slipped 0.16%.
None of this points to a clear zinc catalyst.
04 The Latin American read
Peru’s mines supply a large share of the world’s zinc, and Nexa’s operations are part of that story.
Brazil’s Ibovespa fell 2.68% on Wednesday, which may have weighed on Nexa’s Brazilian assets in investors’ minds.
05 The names to watch
Nexa is the name to watch for Latin American zinc. Teck and Southern Copper offer exposure through diversified portfolios.
Investors who want a pure metal view usually look at the London price, which we could not verify for this report.
06 The outlook
Zinc stocks are likely to follow copper and the dollar in the near term. A softer dollar would help; a rate scare would hurt.
The next test is whether Nexa’s shares can recover Tuesday’s US$11.95 close.
07 What to watch
- London zinc price: A verified move would clarify whether the miners’ shares are following the metal.
- Construction data: Zinc demand follows steel and building activity.
- The dollar: A weaker dollar usually supports metals.
- Peru output: Mine disruptions in Peru would tighten supply.
