The Bom Jardim area is located approximately 30km NE of the Crepori river mouth along theTapajós river. Bom Jardim is a spectacular circular feature suggesting 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 rhyodacites 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 and for copper, gold and molybdenum related to porphyry systems like those existent in the Fanerozoic mountain belts. This model is supported by the discovery made by Rio Tinto Exploration do Brasil ( 1998) of the oldest Au-epithermal system preserved in the world, the V3-Botica. The porphyry model was also proven by Rio Tinto in 1998 with the discovery of the V6 Cu-Mo property located some kilometers north of V3-Botica. Like Bom Jardim, the mineralized volcanic rocks at V3-Botica and at V6 have also evolved during the Uatumã Tectono-Magmatic in the early Proterozoic. Both prospects, V3 and V6 have not been explored by any other company as a National Forest was created over this area and, regulations for exploration and mining have not been established yet by the Brazilian government.

Brazauro has been issued four Exploration Licenses for the Bom Jardim area measuring a total of 37,653 hectares.

An airborne survey (magnetic and radiometric) totalling 4,353 linear kilometers, with flight lines spaced 200 meters, was completed in May, 2008 to support the company to highlight targets for the exploration program.

The combined interpretation of the airborne survey and remote sensing images led to the definition of ten targets which were followed up from October 2008 to July 2009. The exploration program was carried out along two fronts. One front had teams walking all the creeks draining the caldera in search of rock float and out-cropping rocks which could eventually indicate hydrothermalism and mineralization. At the same time these crews collected pan concentrate samples for gold analysis and fine sediments for ICP multi-element analysis. Along the other front, crews carried out grid soil sampling over the pre-defined targets, for gold and base metals analysis.

A total of 134 kilometers of lines were cut for soil sampling and mapping. A total of 1,625 soil samples, 152 pan concentrate samples and 83 sediment samples were collected. During the mapping of the creeks and grids, 462 rock samples were collected and out of this, 111 were assayed.
