Very interesting monthlie and good work!
If you ever talk to the geo again could you ask him; what if there are multiple correlations of surface gold and the images. The signatures found at surface of the Titan that correspond to surface gold, are also found trickling down to considerable depths. If he has time, ask him to plot some of the higher grade surface gold samples, that are associated with structure to the Quantec images and see what conclusion he comes up with. Tell him it may well be worth his while, so that he will do it. To emphasize what you are asking, tell him there are 2 mine shafts down to 100 m that are perfectly correlating with the defined structures of the Quantec. This should pique his interest.
