Here is some fascinating history on company land acquisitions, expected future land acquisitions, and geophysical survey happenings/costs, including to the present day.  Note where Geotech feels obliged to work for JB for free, possibly including the cost of the latest survey.  That mention is somewhere around timepoint 12:30.  This is dated only from November of last year.
