Water is a vital resource for mining exploration activities, so we must to evaluate carefully how much is it affected during this activity. I think that it is necessary to revalue and propose two or more minimal distances according to the experience and research realized. Let’s not allow that a criterion be imposed when not necessarily it will be...
