Abstract: The abundant strategy mineral resource is very role action whether national security or economic benefit.But a number of nonferrous metal mines are short of the mineral resource as a result of exploit long term,for example,tin ore.It is must necessity to prospecting most new mineral resources at fast.Deep seated and around area of Dachang ore field,and Beixiang,Mangchang,Wuxu et al.ore field are new better prospecting regions at Hechi-Nandan tin ore metallogenic belt in guangxi.The way of gas geochemistry,electrtic-chemistry attraction,and geophysics in tunnel are new methods of explore ore.
