I would assume that people are selling because the company doesn't have a process to extract the metal? In theory they do but there is still way too much to do for them to be claiming that it works, don't you think? They have a large resource in the making but it is all worthless unless they can commercially extract it. Until I see results from a larger scale test I will not be a believer. I trust that Dr. Harris knows what he is talking about but hte thing is, he's no longer working with the company which scares me. Do they think they can go it alone without the help of the man who created the process?
