The Crepori prospect is located near the mouth of the Crepori River and the Tapajós River at a distance of 220 km SW from the town of Itaituba. Access is also available by boat through the Tapajós and Crepori rivers.

The prospect lies inside the granites of the Au-fertile Parauari Intrusive Suite (1,883 Ga) near the contact with the volcanoclastic rocks of the Buiuçu Formation (1,890 Ga) to the southwest.

Like many other prospects in the Tapajós, the Crepori's primary mineralization was exposed by garimpeiros’ workings on the alluvial and colluvial materials. The exposed mineralization comprises a quartz-sulfide lode with high grades of gold and possibly Au-rich wall rock alteration zones related to the high grade lodes. The lode is composed by quartz + galena + chalcopyrite ± sphalerite. Fourteen (14) rock chip samples systematically collected on the main lode have returned gold assays in the range between 5.00g/t and 42.00g/t with an average of 13.00g/t Au. As the pits have limited dimension and/or are flooded, no long channels could be sampled yet. Nevertheless, at least three channels in the saprolitic granite, where quartz veining and hydrothermal alteration is identified, have returned gold intercepts like 2.00m @ 4.27g/t; 4.00m @ 5.56g/t and 9.00m @ 4.09g/t. These results are encouraging as it indicates the presence of mineralization in the wall rock material.

At Crepori a camp was built to support exploration. A soil geochemistry survey has been completed and a 1,000 meter drilling program is underway. Assay results are pending.
