Resumen
La región de Magallanes se ha caracterizado a lo largo de la historia por la producción de
combustibles fósiles como; petróleo, gas y carbón, este último mineral ha presentado un alza en su
demanda a nivel mundial el último año, por lo que su precio ha crecido en un 80%
aproximadamente. El área de estudio es el Yacimiento Laguna ubicado a tan solo algunos
kilómetros de la ciudad de Punta Arenas, este yacimiento esta provisto de un único manto de
carbón, el cual dentro del contexto geológico pertenece a la Formación Loreto (Eoceno Superior).
Mediante este trabajo de prefactibilidad se ha logrado realizar un análisis en conjunto, tanto del
modelo geológico como financiero, presentando una metodología mediante la cual los geólogos
puedan entregar un análisis más cercano a la realidad dentro del negocio minero. Mediante el
modelado de 54 sondajes, realizado en el software Civil 3D, se ha logrado obtener el volumen de
estéril y tonelaje de carbón, se ha realizado un análisis global de yacimiento como un punto de
referencia para poder comparar con un modelo por expansiones. El modelo financiero aplicado al
modelo geológico ha dado como resultado una evaluación positiva, ya que todas las expansiones
presentaron un balance positivo, además parámetros como el VAN, que presentó un valor mayor a
cero lo que confirma el resultado obtenido por lo que entrega más valor a la evaluación realizada.
Bajo las condiciones actuales del mercado este estudio de prefactibilidad se considera positivo y
se da pie para un análisis de factibilidad.
The Magallanes region has been characterized throughout history by the production of fossil fuels such as; oil, gas and coal, this last mineral has presented an increase in its demand worldwide in the last year, for which its price has grown by approximately 80%. the study area is the laguna deposit located just a couple of kilometers from the city of punta arenas, it is provided with a single coal seam, which within the geological context belongs to the loreto formation (upper eocene). through this pre-feasibility work, a joint analysis has been achieved, both of the geological and financial models, presenting a methodology through which geologists can deliver an analysis closer to reality within the mining business. through the modeling of 54 boreholes, carried out in the civil 3d software, it has been possible to obtain the volume of waste and tonnage of coal, a global analysis of the deposit has been carried out as a reference point to be able to compare with a model by expansions. the financial model applied to the geological model has resulted in a positive evaluation, since all the expansions presented a positive balance, in addition to parameters such as the npv, which presented a value greater than zero, which confirms the result obtained, thus providing more value. to the evaluation carried out. under current market conditions, this prefeasibility study is considered positive and leads to a feasibility analysis.
