RE: Update on PlayfairI got the same story when I called in today. I wouldn't have bothered if I had read your post 'big Spanish cheese'!!
One thing I think you have a little mistaken is the inversion stuff. I think PLY have already done inversions on the gravity data(and maybe the magnetic data too). It is to help them pick the drillhole locations based on geophysical data and not to analyse what they are finding in the drilling.
Good to have stoxxman on board (at least a little)
