Project Overview

Man of War Project

The Man of War Project is located in the municipalities of São Gotardo and Matutina, Minas Gerais, Brazil. The project comprises four ANM mineral rights covering approximately 4,708.67 hectares (47.09 km²).

The current Inferred Mineral Resource includes the Nau de Guerra, Alto da Serra and Balsamo resource targets. Fragata and Caravela have been identified as additional exploration targets within the same mineral tenure package.

Preliminary metallurgical testwork has been completed on a composite sample from the Nau de Guerra target. The technical report recommends additional drilling, metallurgical testwork, resource updates, environmental assessment and future economic studies.

Mineral Resources are Inferred, are not Mineral Reserves, do not have demonstrated economic viability, and there is no certainty that a mining operation will be realized.
