In 1984, Mineração Novo Astro (MNA) and Mineração Yukio Yoshidome (MYYSA) were awarded concessions for mining on an industrial scale.

Garimpeiros
Gold mining is the resource extraction, extraction of gold resources by mining. Historically, mining gold from Alluvium, alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to Ore, ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, Mining#Human Rights, human rights and Environmental effects of mining, environmental issues are common issues in the gold mining industry.
