You need to set up your Furnace outdoors, and be very concerned about the Fumes... After much examination and testing, I have determined that I know the where-about's to a very rich Copper, Silver and Gold Deposit...
I won't return to the Gold Deposit until "after" the Reset... Plus the Gold is Tiny to Microscopic... I made a big mistake, looking at the Greens and Blues, instead of looking at the Reds and Browns... I dipped the Rock in Vinegar over-night and it revealed more Gold and Silver than ever... The Copper was never hard to see... It does appear to be rich in Copper, for sure...
