Mineral exploration methods vary at different stages of the process depending on size of the area being explored, as well as the density and type of information sought. Aside from extraplanetary exploration, at the largest scale is a geological mineral Province (such as the Eastern Goldfields Province of Western Australia), which may be sub-divided into Regions. At the smaller scale are mineral Prospects, which may contain several mineral Deposits.
Geotechnology is the application of scientific methods and engineering techniques to the exploitation and utilization of natural resources (such as mineral resources).
