Application Of Mineral Exploration Models And Gis To :
the inherent problems of classifying or inventorying potential mineral resources pose specific challenges. In this paper, the application of a conceptual mineral exploration model and gis to generate mineral potential maps as input to land-use policy decision-making is illustrated. We implement the criteria provided by a conceptual exploration model for mineral mapping & mineral classification escondida copper mine, chile for many image requests, a matching image can be located in our global archives of satellite imagery If no satellite map data is available in the archives, new satellite image data can be acquired through a satellite tasking process.the occurrence of a ree-enriched mineral does not necessarily correlate with economic feasibility of mining that mineral deposit; mining companies must also look at ore grade of the deposit to determine its profitability. rees most rees are mined from placer deposits, bedrock, or clay formations (see map below for currently mapped deposits
