This paper stresses the importance of studying and summarizing geologi-cal, geophysical and geochemical characteristies of known ore deposits andtheir geological settings so as to establish ore-prospecting models. It is sug-gested that while using such models to guide ore-prospecting work we shouldattach importance to another type of ore-prospecting work, i. e. the search fornew types of ore deposits, new spieces of ore resources and newly-born oredeposits in areas of comparatively detailed geological investigation, or the per-formance of ore-prospecting work in areas of less geological investigation Inthe latter case, characteristics of ore-prospecting targets are not yet clearlyknown, and it is very difficult to choose some concrete model as the basis ofore-prospecting work;the arrangement of geological work only according tothe train of thought of "modelling ore prospecting" is therefore not proper.The author suggests that studies in this aspect should be strengthened andthe characters and regularity of this sort of ore-prospecting work should beinvestigated on the basis of more extensive metallogenic geological settings forthe sake of guiding the ore-searching work. The author names such ore-sear-ching train of thought "nonmodelling ore prospecting" to distinguish it from"modeling ore prospecting".
