Summary Experience of forecast studies testifies the lack of dominant factors of ore systems development and deposits location. In this connection, the necessary element of a forecast is studying and modelling of self-organized ore-formation systems based on understanding of interrelation between deposits formation and earth interior evolution. Ore formation must be reconstructed on the basis of system analysis methodology. The information for such analysis can exactly be represented by GIS that will enable to find common regularities and common approach to assessment of studied territory perceptivity.
