I'm doing this in honour of a geologist who is stuck in Nevada, when nobody gives a hoot about minerals anymore. This press release attempts to generate some interest in Nevada copper. Actually, those large copper mines are ten times worse than any nuclear waste site!
The geophysics is interesting. They are detecting electrical currents in the ground caused by distant lightning strikes. This is also big for diamond exploration. In our northern Polaris seismic sites, we have also put in permanent MT stations which can support this type of air survey.
