Zinc maintained stability on Monday, September 21, 2026, with London Metal Exchange three-month metal trading near US$3,931 per tonne and cash metal around US$4,018, signalling a tight nearby market despite weakness in Latin American producer equities. Nexa Resources closed at US$12.86, declining 1.15%, while Buenaventura ended at US$33.59, down 2.16%, according to Rio Times market data. The divergence between firm zinc prices and falling producer shares reflects investor caution about miners rather than fundamental weakness in the underlying commodity.
The backwardation structure, where nearby cash metal commands a premium over future delivery contracts, points to immediate supply tightness in the refined zinc market. LME three-month zinc had climbed from US$3,794 to US$3,931 per tonne over the previous five trading sessions, while TradingEconomics quoted zinc at US$3,935.23 per tonne, up marginally 0.04% on the day. Peru remains the anchor for Latin American zinc supply.
Nexa Resources operates five polymetallic mines, including two underground operations in Peru's Central Andes, and runs the Cajamarquilla smelter near Lima, the largest zinc smelter in Latin America. The company also operates smelting facilities at Três Marias and Juiz de Fora in Brazil's Minas Gerais state. An incident at Cajamarquilla on May 13, 2026 disrupted production, cutting an estimated 7,000 tonnes of refined output, roughly 2% of annual volumes.
Nexa expects to recover this output in the second half of 2026 without altering full-year sales guidance. Buenaventura reported second-quarter zinc production of 7,360 tonnes from its Uchucchacua and Tambomayo mines, representing a 5% year-on-year decline attributed to lower ore grades at Tambomayo rather than deliberate volume reductions. Zinc's primary industrial application is galvanised steel coating, used extensively in building, bridge, warehouse and housing infrastructure.
This tie to construction cycles keeps the metal linked to demand patterns in North America and emerging markets, where logistics warehousing has provided steady offtake. Bolivia and Mexico contribute regional supply depth, but Peru's integrated mining and smelting operations give it outsized influence on refined zinc flows to the Americas and Asia. Market participants are watching whether cash zinc can maintain its premium over three-month contracts into October's physical buying season, when galvanisers typically build inventory ahead of winter construction deadlines in the northern hemisphere.
If construction activity in the United States and Europe remains solid, the high US$3,900 to US$4,000 price band should persist, though the question remains whether Latin American miners can convert metal strength into renewed share price momentum. Source: Rio Times, September 21, 2026.
