Australian NP title A Pilbara gold rush guide, page-94

Just a difference of opinion there, your quote on plate tectonics and algal mats is no help quantifying the tonnes and grade of whatever gold there is over there, when I start seeing bulk samples which can quantify the tonnes, grade, grainsize, thickness and orientation of the gold in the ground and down dip then it will be proven.

Until then they are all just theories and I can't name a single producing gold mine that makes money mining geological theories - it's good old boring tonnes and grade that are used to measure potential mines
