The BED has an area with 538 hectares and with an extension of 5,380 kilometers squared with reservation made calculations in 5,5 billion metric tons

To Conceitos Minerao Ltd., it possesses all of the necessary licenses and, it is ready to enlarge the activities of the Mine with larger production.The obtained products present the medium chemical specifications of:[email protected]

RESERVATIONS

The reservation's calculation was subdivided and suitable and inferred based in geological mapeamentos, of which, it originated 10 geological profiles, halfway of 200 meters.

The criterion for the subdivision reserves suitable and inferred was based on the quota of altitude 1.348 meters, that corresponds altitude of the road highway BR 040 (Belo Horizonte - Rio de Janeiro), the where it is observed to the continuity of the mineral body.

The ore above this quota was established as suitable reservation, and, below this quota as inferred reservation. It was also established as maximum depth of the mineralized body the altitude quota 1.216 [email protected]

The ore is carried in trucks, heavy and it proceeds to Porto Dry, or be the place where the same will be accumulated forming a lung for the shipment of the wagons of the railroad.

In Porto I Dry, the ore passes to be put in the wagons, in a proportion of 75 ton to 90 ton for wagon, in a composition of 132 wagons and 2 locomotives totaling an average of 10.000 tons for trip. The time of load is of approximately 5 hours and more 24 hours of trip to his destiny. Porto of Rio de [email protected]

Without to smallest doubt shadow, in this point, or be after the ore to be totally benefitted and ready for the commercialization it is that it begins the saga of the Iron [email protected]

The composition when arriving to his destiny, unloads the wagons for the inferior part of the same ones, in 5 hours in a moega, equipped with a belt carrier with 60 meters of extension that it directs the ore until the Silo-1. Beginning the Port phase of the Logistics. Of the Silo 1 the ore travels more 200 meters of distance to the ore pile which stays to open sky, forming the ore Lung, located in the retroporto, for the shipment of the [email protected]

Of the ore pile the same is carried, with the aid of a foot carregadeira in a new moega to carry the mat carrier that will address the ore until the Silo 2, and this feeds a new belt carrier for more 60 meters until reaching the shiploader, concluding like this the shipment of the [email protected]
