Both are linked to the optimization of profits, which in mineral operations is done by optimizing the ore cutoff grade, considering the block model geometry.

Mineral Resource and Ore Reserve Estimation The

Estimation of a mineral resource is the starting point to successful mine development. A reliable estimate combines good quality and relevant data, competent geological interpretation and a methodology for producing from that data and interpretation, a reliable representation of the mineralized deposit, its geometry, its grade distribution, its metallurgical variability and its density.

Evaluation of Parameters in the Bio-Oxidation Process

The mining districts located in the western mountain range in the south of Ecuador have gold minerals with refractory characteristics, which do not allow gold recovery by traditional methods used in Ecuador. Therefore, it is necessary to apply some technology that permits to obtain greater metal recovery. Bio-oxidation, as treatment of refractory ores that contain low grade of gold, offers an
