Smart dude. There is a lot of science to this metal extraction stuff.

You could be totally pulling my leg, using all this vocabulary Lydia Paley & I were never challenged with in our "Battle of the Spelling Bee" in which we were always the last two standing. (I was a welders helper for a handful of years, and too, I worked on the Alaska Pipeline for 959-ers out Bald Knob Arkansas pickin' steel with hydraulic cranes as an operator apprentice... I was flattered...). I'm into the Sound Money Currency thing and so am pro responsible mining as well...am so well rounded it's amazing I'm single...lol I like what you're doin' and I'm stickin' around cuz you make it interesting and give me an excuse to pick up the Webster's...Yup, I'm that old. Thanks alot for the lesson as it's lots fun on this homebound end.
