Well firstly you need to locate the gold deposit, then with a pick and shovel you start digging followed by washing all the excess dirt from the gold. At this point if you find a lot of gold contact one of the big mining companies and all your questions will be answered.
It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
Alternatively, go back to school, study mining enginneering for 4 year, dont bother getting an M.Sc or MBA, rather go into the industry for 10-12 years , solely to learn that it isnt as easy as it looks, plus the fact that your 4 years in school really only taught you enough to start learnig what its all about, thenand only then, go find soe prospective ground and start spending your hard earned savings.
