Abstract: The prospecting work of Axi gold mine is developed from nothing,the main minerals of Axi gold mine is experienced the repetitive process of Fe to Cu,and then from Cu to Au.The geological material data of the mining are is conducted secondary exploitation and utilization in the process of prospecting,the geological material data such as core samples and sub-samples that are obtained in the early stage of prospecting work in the mining area are tested and analyzed again,it is indicated that the deposit in mining area has further prospecting potential.With the deepening of prospecting exploration work,it is predicted that the Au material resources amounted to 56 t.Based on analyzing a large amount of exploration data of the mining area in depth,combing with field geological investigation results,the ore-bodies characteristics,ores characteristics,wall rock alteration characteristics,ore-forming geological characteristics and ore deposit genesis are studied in depth;then,combing with geological material data that obtained by the former geological exploration work in the mining area,the combination of ore-controlling geological conditions is studied,according to the all kinds of prospecting informations and prospecting methods,the new prospecting model of the mining area is established,and it is applied to the ore-prospecting practice,some ideal prospecting breakthroughs in the mining area are obtained.The above research results show that the secondary exploitation and utilization of the geological material data is the effective way of making prospecting breakthrough.
