re: silver exploration technology
Thanks there acturtle - very informative - i guess that they would also use computer technology to anaysise those results (faster computers - more indepth databasing would maybe lead to cost savings and maximised results)
Potassium as a indicator is not such a bad idea - esp from a science point of view - i know this much that potassium gold and silver are close in that regard.
Drilling technology would also be a area of R and D i would like to see have some money invested in it.
