Located in the municipality of Vazante, the operation of Nexa Resources establishes itself as the largest zinc mine in Brazil and one of the most important in the world.
The largest zinc mine in Brazil is located in the northwest of Minas Gerais, in the municipality of Vazante. The operation, managed by Nexa Resources, not only leads national production of the metal but also stands out globally for having one of the highest grade zinc ores in the world.
According to reports from Nexa Resources itself, the Vazante unit is an integrated complex that dominates the entire production cycle, from underground extraction to the processing of the mineral. The history and scale of this operation show why it is a pillar for the metals industry in the country.
The Vazante Mine: The Undisputed Leader of National Production
The prominence of the Vazante Mine in the Brazilian landscape is undeniable. It is an underground mine that extracts an ore known as zinc silicate, a geological feature particular to the region that guarantees the high quality of the final product.

Brazil extracts 26.3 million tons of ore from what was previously treated as waste, transforming residues into wealth, producing over 3 million tons of sand, and demonstrating how national mining is relearning to generate value.

A hidden mine in the Andes valued at nearly R$ 1 trillion is starting to attract global attention, containing copper, gold, and silver, and raises an intriguing question: why do Argentina and Chile need to act together to exploit this gigantic wealth?
The operation is Nexa Resources’ main zinc asset in Brazil, consolidating the company as the only producer of primary zinc in the country and making the mine a fundamental strategic asset for the company.
The Numbers of Leadership: Production in 2023
The production data from the Vazante Mine highlights its importance. According to results reports from Nexa Resources, the unit was responsible for producing 119,000 tons of contained zinc in 2023.
These numbers reaffirm its position as the largest zinc mine in Brazil and the most productive in operation in the national territory. The company continues to invest in the operation to ensure its longevity and efficiency.
More Than Zinc: The Extraction of Lead and Silver
The geological wealth of Vazante does not stop at zinc. During the processing of the main ore, the operation also generates high-value subproducts.
The mine produces lead and silver concentrates, which are marketed and significantly contribute to the unit’s total revenue. This diversification optimizes the use of mineral resources and enhances the economic viability of the enterprise.
The History of the Mine: From the 60s to the Future
The exploration of zinc in Vazante is a long-standing activity, with operations having begun in 1969. The mine was later acquired by the Votorantim Group in the 1980s, becoming part of Nexa Resources after the company’s metals division was restructured.
Looking to the future, the company is developing the project for the “Deepening of the Vazante Mine”. According to data from the Brazilian Mining Institute (IBRAM), deepening projects like this are essential to extend the lifespan of mines. The goal is to ensure access to new ore reserves and prolong the productive capacity of the largest zinc mine in Brazil beyond 2030.
The Impact in Vazante and in Minas Gerais
The presence of the largest zinc mine in Brazil generates a profound impact on the local and state economy. The operation is one of the main sources of employment and income for the municipality of Vazante and surrounding areas, driving a vast chain of suppliers and service providers.
The collection of taxes and royalties from mining, such as the Financial Compensation for Mineral Exploration (CFEM), is also fundamental for the region’s public budget, funding essential services for the population and boosting local development.
