Geological re-interpretation and resources estimation of “Zona A Oeste” ore deposit

Resumen

The objective of the investigation is to complete the geological interpretation and re-estimation of the resources contained in Zona A Oeste. The origin of the weathering crust apparently on ultramafic rocks only was determined. The areas most likely to have deposits of nickel plus cobalt were identified; that is, the areas with higher potential Lb concentrations. The re-estimation of the resources was developed; obtaining a total of 609 790 t with Ni = 1,19 %, Co = 0,088 % and Fe = 39,52 %.
