This paper describes a method for getting the geological, mineralogical and geochemical information from an ore deposit or prospect area and its ore body. The information is needed to select a suitable hydrometallurgical processing method. Usually the first step is to go through expensive and time- consuming field explorations and a number of rock sample analyzing processes. By using existing public deposit information for that purpose, it could be possible to save time and money. A literature study was done about possible sources of public geological information related to world’s ore mineral deposits. The study included also a couple of experimental cases where the information-searching procedure was tested in practice. The test minerals were gold and lateritic nickel. The results of the tests show that there are different kinds of mineral deposit databases and that in most cases it is possible to find the needed information. It was found that there are benefits in this type of information gathering system, but there are also some downsides such as the reliability of information.
