The following table will show TOTAL RESERVES and RESERVES PER PROCESS which sum up this work of cubic measurement. The estimate of reserves was carried out through the integration system of transversal topographic-geologic sections, which are registered on the detailed geological charts of the Targets and their respective geological sections. As the area of occurrence of graphite ore outcrops throughout the extension of the target, the following methodology was applied:
 
             Chereco Target
             Erom Target
             Madalena Sul Target
             Extensão Nordeste Target
             South Excavation Region
             Norte Sul Target
             Juamirim Target
             Madalena Norte Target
