          Abstract

          This paper presents the implementation of the MineSight® tools in a theoretical project based on the Las Cuevas mine. The project relies on conventional modeling, project configuration, deployment, drilling handling and the creation of the geological and block models that make it possible to reliably determine the exploitable mineral resources of interest. An overview of the project is presented along with a theoretical case study beginning with the generation of polygons in sections representing the seams, using the true thickness tool. After this, economic envelopes were presented using the MSOPIT and MSVALP tools, together with some coal mining requirements. Finally, operational pits were designed using the Pit Expansion tool in order to optimally exploit the site and facilitate economic balance throughout the project. Upon finishing this, the Interactive Planner (IP) tool was used to carry out short-term planning.

          Este trabajo expone la implementación de herramientas MineSight® en un proyecto hipotético que será tomado como base en la mina Las Cuevas, apoyado en la modelación convencional, configuración del proyecto, desiegues, manipulación de sondajes, la creación del modelo geológico y de bloques, que permita determinar con confianza los recursos explotables del mineral de interés. Se presentan las generalidades del proyecto seguido de un caso de estudio hipotético, que inicia con la generación de polígonos en secciones para mantos con la utilización del true thickness, seguidamente se presentan las envolventes económicas en MSOPIT y MSVAL con algunos requerimientos para la minería de carbón. Posteriormente se realizan pits operacionales utilizando la herramienta Pit Expansion tool con la cual se busca explotar el yacimiento de manera óptima y facilitar el equilibrio económico a lo largo del proyecto, en su culminación se realiza el planeamiento a corto plazo con la herramienta Interactive Planner (IP).

          A METHODOLOGICAL MODEL TO ASSIST IN THE OPTIMIZATION AND RISK MANAGEMENT OF MINING INVESTMENT DECISIONS

          Identifying, quantifying, and minimizing technical risks associated with investment decisions is a key challenge for mineral industry decision makers and investors. However, risk analysis in most bankable mine feasibility studies are based on the stochastic modelling of project “Net Present Value” (NPV)which, in most cases, fails to provide decision makers with a truly comprehensive analysis of risks associated with technical and management uncertainty and, as a result, are of little use for risk management and project optimization. This paper presents a value-chain risk management approach where project risk is evaluated for each step of the project lifecycle, from exploration to mine closure, and risk management is performed as a part of a stepwise value-added optimization process.
