If buried too deep in the metal, the general prospecting, you also hard to find it out, dig out does not necessarily is what you want. As policy deepening of exploration, the exploration precision will be falling, exploring the accuracy of below 10 cases, there is no need to go to explore. Metal exploration can exploration ten meters, eight meters, that is cheat consumers, no trust!
