So I'm guessing someone found gold in turkey gizzards? I have found gold in chicken gizzards, I grew up in Central West NSW and we killed all our own chickens, Dad was the only one that would eat gizzard though, but i would make sure I opened them all up for a look. Gold, gems, quartz, pyrite, shotgun pellets.
I was only telling a mate that is super new to prospecting about it the other day and he didn't believe me. I said to him if you spent 6 or 7 years of your life a foot from the ground picking through gold bearing gravel and dirt 24/7 collecting anything that shines I'd imagine you would have a pocket full of the stuff.
