Campo do Cercado deposit

Name(s) in local language(s):

Mina Osamu Utsumi, Campo do Cercado, Caldas, complexo alcalino de Poços de Caldas

Uranium mine in the Campo do Cercado deposit closed in 1997, studied as a natural analogue for nuclear waste disposal.

The open pit mine is a Breccia pipe uranium deposit.

The Osamu Utsumi mine is localized in a relatively permeable breccia dike of 0.5 km diameter that lies adjacent to a small syenite intrusive.

The whole mine area is located within the 30 km diameter Poços de Caldas caldera.

The mine was the first Brazilian mining-industrial complex for the production of uranium concentrate and began operation in 1982.
