I totally agree we all could use a refresher course before persuing further investment oportunities.  If it wouldn't be too much trouble, could you please give me a link for this statement:

The fact of the matter is, only about 1 in 1000 projects will ever make it to be a mine. Of those 1000 projects in excess of 800 will have geophysical anomalies. That means that of the vast number of anomalies most never amount to anything. Most of them can be compared to other massive deposits and even those never become a mine.
