osman is a agent of blanes or a paid associate. A member since not so long ago he knows all about everything, have a look at his past posts. No where in nature will you find 1 kg of pure copper so yout test parameters are unrealistic for a start.

Carl has quite a few thousand dollars to lose if you can accurately find a target every time. Why do you think Carl and his money are still together? go to the
www.finders.com.au website and osman is ottoman or something like that there. He has dozens of aliases the creep.
