Even After More Than Three Decades of Inactivity, Cooperatives Try to Revive the Legendary Gold Rush That Marked the History of Brazilian Mining.
The legendary Serra Pelada mine, located in southeastern Pará, remains alive in the national memory. Officially closed in 1992, it continues to symbolize wealth, hope, and tragedy. Even after 33 years, former miners and local cooperatives still dream of reactivating operations, seeking to turn the past into opportunity.
Throughout the 1980s, Serra Pelada became the epicenter of the gold rush in Brazil, attracting thousands of people from all regions of the country. According to data from the National Department of Mineral Production (DNPM), more than 100,000 workers gathered in the region, creating a makeshift city in the jungle. In addition, the discovery of a gold nugget in 1979, made by a cowboy along the banks of the Grota Rica river, marked the beginning of this historical rush.
The Peak and Decline of Mining in Serra Pelada
During its peak, in 1983, gold extraction reached its highest point, with 17 tons of gold taken from the land of Pará, according to official data from the DNPM. However, as the pit deepened, the risks increased drastically. Landslides, mercury contamination, and hazardous working conditions began to draw attention from authorities and environmentalists.

Without producing a single ton of copper today, Argentina wants to become one of the ten largest producers of the metal in the world by 2035, betting on the Andes deposits and billion-dollar incentives from the Milei government to unlock projects that have been stalled for decades.

Brazil seeks to transform natural resources, energy, mining, oil, and gas into sustainable wealth with strong engineering, competitive industry, technology, productivity, and long-term planning.

Gold, silver, and copper appear near the surface at Filo Sur, making mining companies look at San Juan as a new treasure map in the Andes.

Geological Service of Brazil finds high concentrations of rare earth elements in a strip that stretches from São Paulo to Santa Catarina, including cities like Joinville and Garuva. Samples recorded more than 8,000 parts per million, a level considered significant for this type of occurrence.
As a result, in 1992, then-president Fernando Collor de Mello ordered the immediate cessation of activities, citing safety reasons and irreversible environmental damage. Thus, the immense crater became a murky lake, a symbol of an era of wealth and suffering.
Despite this, hope never faded. Many miners returned to the site, believing that there is still gold in the depths of the old mine. Among them, Chico Osório, a former miner who has lived in Curionópolis since the 1980s, claims that “the land still holds fortune.”
Cooperatives Face Barriers and Internal Disputes
Currently, the Serra Pelada Miners’ Cooperative (Coomigasp) leads the movement for the mine’s reopening. However, the process is slow and complex. On one hand, environmental requirements from Ibama and the Pará State Department of the Environment impose rigorous studies on the impact of the activity. On the other hand, internal disputes among members delay decisions and hinder the progress of projects.
Furthermore, the accumulated debts and degraded infrastructure make any operation difficult. Corroded stairs, unsafe ramps, and obsolete machinery represent serious accident risks. Still, the members insist that reactivation is possible, provided there is technical support and public funding.
The Social and Environmental Impacts of the Past
During the 1980s, Curionópolis — the city that houses Serra Pelada — experienced explosive growth. In just three years, the population skyrocketed from 3,000 to over 40,000 residents, according to IBGE. However, the unregulated growth brought severe consequences: violence, diseases, and environmental degradation.
The indiscriminate use of mercury contaminated soils and aquifers, leaving marks that persist to this day. Therefore, any attempt to reactivate the mine needs to balance economic development with environmental responsibility. Experts from the Geological Survey of Brazil (SGB) assert that the new phase must prioritize clean technologies and constant monitoring to avoid repeating past mistakes.
The Dilemma Between Progress and Preservation
While Coomigasp tries to gather resources, federal authorities discuss whether the site can produce again without compromising the Amazon. However, the challenge goes beyond the economy. Reopening Serra Pelada would mean confronting the historical dilemma between growth and sustainability.
According to mining experts, the region still has significant gold potential, capable of generating jobs and attracting investments. However, the environmental cost could be too high. Even if the gold shines again, reactivation will only be feasible if there is governance, transparency, and social-environmental commitment.
More than thirty years later, Serra Pelada continues to be a mirror of Brazil — where ambition and inequality mix with hope and courage.
Thus, the big question remains: will the new generation of miners be able to transform the old gold rush into a symbol of sustainable mining, capable of uniting progress and preservation?
