Today’s Focus
Zinc tracked through Latin American miner shares split on Wednesday, August 12: Nexa Resources closed at US$14.57, a gain of 0.83%, while Buenaventura rose 0.64% to US$34.80.
The moves were not driven by a single zinc-specific headline. Investors weighed broader metals sentiment, where tame US inflation data had cooled Federal Reserve rate-hike bets and steadied gold, but the zinc proxies took their own paths.
For readers across Latin America, the practical takeaway is that zinc exposure through Nexa, the Peru- and Brazil-focused producer, edged out Buenaventura, the Peruvian precious and base metals miner, even without a sharp change in the underlying industrial metal’s story.
The session highlights how two equities that both carry zinc can diverge on company-specific positioning, liquidity and investor perceptions of their broader metal mixes.
What matters today. The market offered no single zinc catalyst, but Nexa’s and Buenaventura’s gains show the metal itself set the tone as much as stock-level factors on a quiet day.
01 The session in one read
Zinc’s Latin American proxies split on Wednesday, August 12. Nexa Resources, the Peru- and Brazil-based producer, gained 0.83% to US$14.57.
Buenaventura, the Peruvian miner with zinc alongside precious metals, moved in step, rising 0.64% to US$34.80.
The lack of a single dominant catalyst meant investors read the two names more as company stories than as a unified bet on zinc.
The picture from the two named proxies is one of modest divergence rather than a decisive zinc move. Nexa Resources added 0.83% to US$14.57, while Buenaventura rose 0.64% to US$34.80, with no company statement or exchange filing explaining the gap on Wednesday, August 12. Broader market colour pointed to easing US rate-hike fears after tame inflation data, but that supported gold more visibly than zinc. The variable to watch is whether Nexa can hold above US$14.50 in the next session or whether its gain fades without fresh demand news from construction or galvanised steel buyers.
02 The board
The only two verified zinc-linked price points for the session were Nexa Resources at US$14.57 and Buenaventura at US$34.80.
Nexa’s 0.83% rise led the zinc proxies, and Buenaventura’s 0.64% gain showed both Latin American names moving in step.
The wider regional scoreboard had been mixed, with Peru’s BVL S&P index registering a 0.13% gain, but that did not translate into uniform strength for the zinc names.

03 What moved it
No company-specific filing from Nexa Resources or Buenaventura explained the moves on the day. Investors appeared to respond to tone rather than headlines.
A tame US inflation report on August 12 eased Federal Reserve rate-hike bets, which helped stabilise gold. That macro shift gave metals a slightly friendlier backdrop, but zinc’s industrial demand story did not produce a fresh trigger.
With zinc tied to galvanised steel, construction and infrastructure, investors are still waiting for a clearer demand signal. The muted session suggested no new order book or inventory data arrived to force a stronger move.
04 The Latin American read
For foreign investors, the session showed that zinc exposure across Latin America is not monolithic. Nexa Resources, with its Brazilian and Peruvian operations and direct zinc focus, gained, and Buenaventura also firmed.
Peru, Bolivia and Mexico matter for zinc supply, but the two exchange-traded proxies most used by international investors are the US-listed shares of Nexa and Buenaventura.
Brazil’s real closing near 5.18 per US dollar was a reminder that currency moves also colour returns for dollar-based investors in miners with local cost bases.
05 The names to watch
Nexa Resources closed at US$14.57, up 0.83%. The gain kept the stock in positive territory without any fresh operational announcement.
Buenaventura ended at US$34.80, up 0.64%. Its broader precious-metals mix may have made it less responsive to the day’s industrial-demand signals.
Both names remain the practical way for international investors to proxy zinc through Latin American listed equities, even when the metal’s own spot price is not quoted directly in the public board.
06 The outlook
With no fresh zinc catalyst on August 12, the next move will likely depend on construction and galvanised-steel demand data, especially from China’s property complex or Latin American infrastructure budgets.
Investors should also watch whether Nexa’s outperformance holds if broader metals sentiment cools again. A reversal below the US$14.50 area would suggest the gain was more tactical than fundamental.
07 What to watch
- Galvanised steel demand: Construction and infrastructure buying offers the clearest read on zinc consumption and would directly affect Nexa and Buenaventura.
- China property data: As the largest zinc consumer, any fresh Chinese construction or credit figures could set the next short-term direction.
- Nexa above US$14.50: Holding that level would signal continued investor confidence after the 0.83% gain.
- Buenaventura follow-through: Holding above US$34.80 would show buyers staying with the Peruvian miner despite its mixed metal profile.
