Abstract
GEOEXPLORER is a knowledge-based system under development, to support exploration and assessment of supergene deposits. Some existing expert systems, such as PROSPECTOR have been designed mainly for regional resource assessment or for mineral deposit prospecting. In contrast to that, GEOEXPLORER shall not only deal with problems of searching for mineral deposits (deposit prospecting), but it shall also cover the evaluation of the spatial occurrences as well as of the economic values of deposits (deposit appraisal) . Besides, an interface to an external data base is taken into account. This paper gives an outlook of the development of GEOEXPLORER.
