Operation ceased in 2007.
Presently (2014) the same area is still operated by 1,500 to 2,000 independent miners during the dry season, known as Areinha claim.
It is a very controversial situation, as the mining rights still belongs to Rio Novo mining company.
The company is in favor of transfering its rights to the independent miners association, but there is a judicial claim from the public prosecutor enforcing the company to perform the environmental rehabilitation - what certainly cannot be done while independent miners are active in the locality.
On the other hand, the city government cannot afford the huge social cost that the closure of the area would generate for more than 1,500 families who lives in the city.
So far, no solution for the situation was found.
