so its clear they are not using xrf on tesoro and that xrf and pima are different...and they tell us pima was used on vilcoro in the past ,..but they still havent said they are not using pima currently and more importantly on the tesoro..i have submitted this more precise question. ------- It would seem we are getting into detail about different types of onsite testing so i will be more clear regarding this question. At any time during the exploration of the tesoro project from start until present, has PIMA been used as a tool to further exploration? thankyou for your time.
