The focus of the mining industry is shifting towards potential new resources in remote areas as a result of decreasing ore grades. Remote sensing technology is an effective and widely established analytical method for geology and mineral exploration and has proven extremely beneficial by providing access to dangerous or previously inaccessible mineral deposits.
Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.
