Stevejs,
I am not sure how you think having an address for Salt Gold Chile Limitada is going to tell you anything about the legitimacy of the concessions and MMTE's attempt to purchase them.
If they are owned by a corporation controlled by a private individual in Chile, which they most likely are, the address is probably the private residence of this individual. What will that tell you about MMTE"s involvement with the mining claims?
I suggest you email or call the CEO with your questions at this point rather than asking other posters on the board for the answers.
By the way, I am most assuredly an investor.
Good luck in your DD efforts.
