yup, that's my source all right.
but I'll be vapulated if I can find any confirmation that suritorous (or anything like it) relates to gold...

I don't know if you're just playing with us, tsuwm, but it would appear highly likely that suritorous is a typo for auritorous. What with "s" being next to "a" on the keybosrd, I find thst I mske thst ailly aort of miatske sll the time.

Mind you, I couldn't find a listing anywhere for auritorous either, except for an astrological one (are you a Scorpio auritorous?), but I know that your word wells are deeper than mine.
