For John Yellich, the only thing that is CURRENT that I could find out about him was his home phone number, which I'm certainly not going to post on here.
However, there was a lot of stuff from back in the 90's. Apparently he's been associated as a geologist with more than one company, the latest one (that I could find) was with Maxam Gold Corporation. That name rings a bell with me. Anyone heard of it?
So, yes, John Yellich is definitely a geologist. Once again, that doesn't prove whether he's any good or not, but he's definitely a geologist. I gathered from looking at some of the old stuff that he must be 63 years old right now......the latest dates I could find out anything about him was in 2006 and there it mentioned his geological report with Perihelion and also his association with Maxam Gold. I went to the Maxam gold website, but didn't see his name anywhere. But 2006 was two years ago so he could've retired. Who knows?
