The Bravo mine is an open pit mine, with numerous and conspicuous outcrops of ore from the earth. The surveys and the final reports filed and approved by the DNPM showed the presence of large deposits of manganese that can be easily exploited. The other manganese rich areas around this concession are also under the ownership of WCA Group.
The manganese of Bravo is found already in nature of high quality and needs a less complex beneficiation because it reaches standards of min. 50% of manganese content already via crushing and screening. Due to its purity and high Mn concentration, the final product is particularly indicated for the domestic producers of fertilizers for the soy, grain, wheat and sugar cane farms.
