Resource Estimation in a Rock Salt Deposit, Brazil- A case study

This work presents the results of Geological Modeling and resource estimation of a salt deposit, in an eastern margin basin of the Espirito Santo state - Brazil. This work had, among other objectives, the geological evaluation of the evaporite sequence in the onshore part of the basin and delimitation of the area of occurrence of soluble salts. Therefore, the object of study focuses on the Mariricu Formation, which is composed of the fluvial continental Mucuri and evaporitic Itaúnas members. It is the essentially evaporitic unit, in which the rock salt deposit is found. Through modeling, a total resource of the order of 4.65x109t were estimated. Which are grouped into the following categories: measured resources of the order of 4,38x109t, with an average of 85,40% NaCl, indicated resources 0,23x109t, with an average of 84,63% NaCl and inferred resources 2,1x106t, with an average of 76,63% NaCl. These are interesting resources and should be considered.
