Did you know?
You can earn activity points by filling your profile with information about yourself (what city you live in, your favorite team, blogs etc.)
But thats as far as I could get also. I doubt if we will find out anything anyway. The best way would to be to access the mineral data base for Peru. You would at least find something there, but info would still be limited because of slack reporting requirements in previous years. I don,t beleive I could access that data base, and if I did, I would still run into the language barriers.
