Let’s see now, i met Roberto in person, asked him a bunch of questions...got a bunch of answers. I saw him monitoring all aspects of doing what he has expertise in, each n every day I was at the site. Just a couple weeks back. Very nice person, knows his stuff (I’m only an amateur) and is proving it daily (as you type away). So I guess “hands on” is verified by “Boots on”. Maybe you should make arrangements to go see and ask questions for yourself and report back to all of us about what you learn at St Elena. Come back and enlighten us please!!! You sure seem to know a lot about this operation and all those involved. I’ll understand your hesitation if your scared of the hot desert heat in a foreign country though. Bandito’s n all. Cheers
