History
Nexa built its Aripuanã zinc mine, bought out its partner, and funded it with debt, but a late start and a difficult ramp-up followed.
2018-2019: Approving Aripuanã
In 2018 Nexa Resources focused on its Aripuanã zinc-lead-copper project in Mato Grosso, Brazil. The Preliminary Environmental License arrived in April. In September the board approved a buyback of up to US$30 million of shares, running from November 2018 to November 2019; the record does not say how many shares were bought. On October 19 the board approved construction after a feasibility study showed first-time reserves of 26.2 million tonnes, capex of about US$392 million, a 13-year mine life and production starting early 2021. Nexa held 70% and planned to pay from cash and operating cash flow. The Installation License followed on December 20, 2018.
Nexa met its 2018 mining guidance for all metals, including 373 kton of zinc. For 2019 it guided to 375-395 kton of zinc and capex of about US$420 million, of which about US$140 million was for Aripuanã.
The open question was whether Karmin, the 30% partner, would fund its share. In August 2019 Nexa answered by agreeing to buy Karmin for an aggregate US$70 million in cash from cash on hand. The deal completed on October 30, 2019, giving Nexa 100% of Aripuanã. Karmin's other assets went to a separate company, Kar Gold.
2020-2021: Debt, delays and a delisting
In March 2020 Nexa published an early-stage economic study for its Hilarión project in Peru. It envisioned a 16-year underground mine averaging about 115kt of zinc a year, with capex of US$585 million. Nexa called it conceptual, with a pre-feasibility study still to come.
COVID-19 then hit. In April 2020 Nexa drew the full US$300 million of its revolving credit facility, maturing October 2024, to strengthen liquidity, and weighed cutting costs and postponing spending. In July it signed a loan of up to R$750 million (about US$140 million) with Brazil's development bank BNDES for Aripuanã, maturing in 2040. This was the project's first specific debt, despite the earlier plan to use cash.
The operating license for Aripuanã came on October 7, 2021, later than the end-2020 expected earlier. Commercial production slipped from 2021 to 2022. In November Nexa delisted from the Toronto Stock Exchange, citing the burdens of the listing and minimal trading volumes there; the last Toronto trading day was November 30, 2021, and shares remained on the NYSE. It said it intended to stop being a reporting issuer in Canada, and the outcome is not seen in the record.
2022-2024: Returns and a difficult ramp-up
In February 2022 the board approved a US$50 million distribution, about US$44 million as cash dividend and about US$6 million from share premium, based on 132,438,611 shares outstanding at the end of 2021. It was payable on March 25, 2022. That month Nexa Resources Perú also announced early redemption of all US$128.47 million of its 4.625% notes due 2023, set for March 28, 2022. The record is then quiet until 2024.
By October 2024 Aripuanã was struggling. Nexa cut its 2024 zinc guidance there to 31-42 kt, down 26% at the mid-point, blaming lower ore volumes, fewer working days, lower grades and filter and flotation problems. Group zinc guidance of 323-381 kt was kept, and guidance was raised at Cerro Lindo, Vazante and Atacocha. Mining cash cost guidance was lowered to US$0.03-0.20 per pound of zinc, and capex to US$300 million. The Morro Agudo mine was sold, closing July 1, 2024.
2025-2026: A new dividend policy
In January 2025 Nexa adopted a dividend policy effective January 1, 2025: up to 20% of free cash flow before significant non-recurring events, with a minimum of US$0.08 per share, for fiscal 2024 onwards. In December 2025 it sold its Otavi project in Namibia North for US$3.0 million plus up to US$7.0 million contingent, keeping a royalty.
As of July 2026, Nexa had 132,438,611 shares on issue and operated Cerro Lindo, El Porvenir and Atacocha in Peru and Vazante and Aripuanã in Brazil. In the first half of 2026 it drilled 123,455 m in total. Aripuanã's planned geophysics survey was deferred to the second half because of operational delays.
