Thankyou for this. It seems I recall that superimposing the surveys available is a good method of narrowing down the drill targets. What is being looked for is generally dense, can be magnetic in various compound forms and is conductive. If you have an indication of a change from background in three of the surveys, than you can be sure there is something different down there which makes it interesting. Looking at the info available, there appears to be some anomalies screaming to be drilled. So far the science has a pretty good batting average.
