- Peru’s Buenaventura rose 2.06% to US$31.15 and Teck 1.45% to US$65.74, as silver and gold miners rallied.
- Brazil’s Ibovespa fell 1.06%, which weighed on Nexa, a miner with mines in Brazil and Peru.
- The UUP dollar fund fell 0.41%, a softer dollar that normally helps metals.
Today’s Focus
Zinc miners split on Thursday 15 October. Nexa Resources, with mines in Peru and Brazil, fell 1.34% to US$12.48, while Peru’s Buenaventura rose 2.06% to US$31.15.
The split follows precious metals, which rose on the day and lifted Buenaventura, a producer of gold, silver and base metals. Nexa’s fall matches a weak day for Brazilian assets.
We have no confirmed London Metal Exchange zinc price for the session, so the miners are proxies.
What matters today. Peru is a major zinc producer, and Thursday’s split between two miners shows that gold and silver can outweigh zinc in a share price.
01 The session in one read
Nexa Resources lost 1.34% after a 3.5% drop on Wednesday, from US$13.11 to US$12.48 in two sessions. Buenaventura gained 2.06% after losing 3.1% a day earlier.
Teck Resources, a zinc and copper miner, rose 1.45%. The split suggests that company mix mattered more than zinc itself.
Assessment — Company mix, not the metal LOW
Buenaventura’s gold and silver exposure helped it, while Nexa tracked Brazil’s weak market. We could not confirm the zinc price, so the metal’s own direction is unknown.

The session read
The Ibovespa eased 1.06%, with breadth positive — 4 of 5 names higher. BVL PERÚ led, while COLCAP lagged.
03 What moved it
We found no zinc-specific news for Thursday. Precious metals rallied, and Brazilian assets fell, and the two miners followed those themes.
Nexa sells zinc and trades with Brazil’s market, while Buenaventura trades with gold and silver.
04 The Latin American read
Peru is among the world’s largest zinc producers, and Nexa operates mines there and in Brazil. Peru’s own market was not measured in our data for the day.
Mexico also produces zinc, but we saw no move tied to the metal.
05 The names to watch
Nexa and Buenaventura are the main US-listed Latin American zinc plays. Teck adds Canadian and Chilean exposure.
Their different moves show why miners are imperfect proxies.
06 The outlook
A confirmed zinc price would show whether the metal itself moved. Until then the miners’ gap is the best signal.
Brazil’s politics and precious metals are the near-term drivers for the two names.
07 What to watch
- Zinc price: We will report a confirmed zinc price when one is available.
- Brazil: The runoff on 25 October is the main risk for Nexa’s home market.
- Precious metals: A fall in gold would hit Buenaventura.
- US data: US industrial production for September is due at 13:15 UTC on Friday 16 October, with a forecast of +0.4%.
Background: Nexa Falls 3.5% to US$12.65 as Buenaventura Drops 3.1%.
Background: Brazil Stocks Fall 1.06% as Real Weakens.
