Abstract
Seismic surveys have been used for potash prospection in the Catalonian Potash Basin since the early 1970’s. More recently, 3D high-resolution seismic surveys have proved to be a powerful tool for potash mine evaluation and planning when professionally designed by geophysicists in collaboration with mining companies. Interpretation by mining geologists for mining engineers is key to achieving an improved geological understanding of the mine. In this case study in-depth seismic interpretation made it possible to obtain a structural geology model as well as produce isobath and isopach maps. The resources were evaluated after a drilling campaign and a calculation of on-site resources was made using geostatistical methods in compliance with International Standard Codes for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code).
