• Development and control of operational and economic KPIs. • Design of drill pattern and powder factor using operational, geometrical and economic criteria. • Cost control of unit operations (Drilling, blasting and tramming) • Increase by 20% the meters / blast, maintaining a continuous monitoring and better distribution of explosive charge. • Increase in the use of ore tramming equipment (Scoops and Dumpers) by 10%, by reducing operational delays.

• Planning and monitoring of production and advance programs vs Budget to short, medium and long term. • Mining infrastructure design • Development of standards and procedures of the activities of the planning area
