The Bom Jardim/Circulo area is located approximately 30km NE of the Crepori mouth at theTapajós river. The Bom Jardim/Circulo is a spectacular circular feature resembling a large volcanic caldera. The geology of the area is composed of intermediate-acid volcanic rocks of the Uatumã tectono-magmatic event (1,900-1,882 Ma). The volcanic rocks are dacites and latites of the Bom Jardim Formation and dacites and rhyolites of the Salustiano Formation.

In this area Brazauro aims to explore for gold deposits related to epithermal systems like those existent in the Fanerozoic mountain belts. This is supported by the discovery made by Rio Tinto Exploration Brasil in 1998 of the oldest Au-epithermal system (V3-Botica) preserved in the world. Like Bom Jardim, the mineralized volcanic rocks at V3-Botica are also of the Uatumã event from the Salustiano Formation.

Brazauro has been issued an Exploration License for the Bom Jardim/Circulo area measuring 37,652.8 hectares and exploration will follow soon.
