Key Facts
- Nexa Resources fell 2.42% to US$12.88 on Monday 12 October, down from US$13.20 on Friday.
- Buenaventura slipped 0.49% to US$32.30, a gold, silver and base-metals miner in Peru.
- Nexa mines zinc in Peru and Brazil, so its New York shares are a direct listed proxy for the metal.
- The US dollar index rose 0.35% to 102.57, a mild headwind for metal producers.
- We found no company news behind the moves, and could not confirm a zinc price move on the day.
Today’s Focus
Latin America’s zinc miners fell on Monday 12 October. Nexa Resources lost 2.42% to US$12.88 in New York, and Buenaventura slipped 0.49% to US$32.30.
Nexa operates zinc mines and smelters in Peru and Brazil, and it is the most direct US-listed zinc play in the region. Buenaventura is more diversified, with gold and silver alongside base metals.
We found no announcement from either company, and we could not confirm a move in the zinc price itself. The wrap therefore reads the shares only.
What matters today. Zinc miners with Peruvian mines sold off in New York, but we found no fundamental news to explain it.
01 The session in one read
Zinc proxies were lower on Monday 12 October. Nexa fell 2.42% to US$12.88, and Buenaventura fell 0.49% to US$32.30.
The gap between the two suggests that investors sold the purest zinc exposure first.
Assessment — Miners pull back without news MEDIUM
The sell-off was modest and unexplained. The variable to watch is whether Nexa stays above US$12.50 over the next sessions.
02 The board
Nexa took the larger loss because zinc drives most of its revenue. Buenaventura’s gold and silver output cushioned its decline.
These prices are proxies, because neither share is the zinc price. A share can move on costs, debt or local news as well.

The session read
The Ibovespa rose 1.38%, with breadth evenly split — 2 of 4 names higher. IPC MEX led, while BVL PERÚ lagged.
03 What moved it
We could not confirm a single driver for Monday. The dollar index rose 0.35% to 102.57, which weighs on many commodity shares.
Without company news, the move reads as sector positioning rather than a verdict on zinc demand.
04 The Latin American read
Peru is among the world’s largest zinc producers, and Mexico is also a major supplier. Zinc is used mainly to galvanise steel against rust.
That link ties the metal to construction and infrastructure spending across the hemisphere.
05 The names to watch
Nexa Resources is the cleanest listed zinc bellwether in Latin America. Its Peruvian and Brazilian operations make it sensitive to the metal.
Buenaventura offers diversified Andean exposure. Watching the gap between the two tells investors whether pressure is zinc-specific.
06 The outlook
The next sessions will show whether Monday’s fall was a one-day move. Investors will watch Nexa’s price near US$12.88 and any Peruvian supply news.
We could not confirm the zinc price on Monday, which is the main data gap in this wrap.
07 What to watch
- Nexa near US$12.88: A close below it would suggest further selling.
- Peruvian mine news: Output or labour news changes the supply outlook.
- Galvanised steel demand: Construction orders set the long-run demand for zinc.
- US dollar index: A move above 103 would add pressure.
Frequently Asked Questions
Why did Nexa Resources fall on Monday?
We found no company news. Its New York shares fell 2.42% to US$12.88, in a modest move for zinc miners.
Why does Peru matter for zinc?
Peru is among the world’s largest zinc producers, and Nexa operates mines there.
What is zinc used for?
Most zinc galvanises steel to protect it from rust, so demand follows construction and infrastructure.
Is Buenaventura a zinc stock?
Buenaventura is a diversified miner with gold, silver and base metals, so it reacts less to zinc than Nexa.
