dc.description.abstractLos estudios conceptuales son generalmente la primera valoración económica de un proyecto minero. Bajo este contexto, el objetivo principal de este trabajo es formular un estudio técnico y económico de la viabilidad potencial de los recursos minerales de elementos de tierras raras (Rare Earth Elements, REE) en el departamento de Antioquia mediante la simulación geoestadística por bandas rotantes del tenor de óxidos totales de tierras raras (Total Rare Earth Oxides, TREO) y el análisis de los factores modificadores, para valorar un programa de prospección detallada en los blancos o targets de exploración. Los datos del tenor de REE en Antioquia se construyeron durante el 2004-2007 en el proyecto “Mapa geoquímico del departamento de Antioquia”. El tenor de TREO se procesó mediante las herramientas computacionales Isatis, ArcMap, QGIS y geoportales de la Agencia Nacional de Minería (ANM) y del Servicio Geológico Colombiano (SGC). Se obtuvo dos targets con potencial de prospectividad para desarrollar la cadena de valor de REE en las subregiones del Nordeste y Bajo Cauca, con una estimación de recursos inferidos de 5,444 millones de toneladas a un tenor de 0.09% de TREO, equivalentes a 4.9 millones de toneladas de TREO. Para materializar un negocio minero de REE en Antioquia se requiere inicialmente la inversión de un programa técnico de prospección detallada sobre un área de 2,150 km2, presupuestado en 1.84 MUSD.

dc.description.abstractScoping studies are generally the first economic appraisal of a mining project. Under this context, the main objective this work is to formulate a technical and economic study of the potential viability of mineral resources of REE in the Antioquia department through geostatistical simulation by turning bands of total rare earth oxides (TREO) grade and analysis of the modifying factors, to assess a detailed prospecting program in exploration targets. REE grade data in Antioquia were constructed during 2004-2007 in the project "Geochemical Map of the Antioquia Department". The TREO grade was processed using the computational tools Isatis, ArcMap, QGIS, and National Mining Agency (ANM) and the Colombian Geological Service (SGC) geoportals. Two targets with prospectivity potential were obtained to develop REE's value chain in Nordeste and Bajo Cauca subregions, with an inferred resource estimate of 5,444 million tons with TREO grade of 0.09%, equivalent to 4.9 million tons of TREO. To materialize a REE mining business in Antioquia, the investment of a technical program of detailed prospecting is initially required over an area of 2,150 km2, budgeted at 1.84 MUSD.
