James, great photos. Could you please tell us what we are looking at?
Still new to the ewaste gold recovery field, so I'll try my best at individual identification. Perhaps the more experienced can help?

I have found solid gold bonding wires, but in a much finer screen size. I don't have any pics as I took all my screen sizes and ground everything in my sophisticated grinding apparatus (a coffee bean grinder liberated from my wife’s kitchen :shock
. She doesn't like coffee anymore, so I think I'm OK :?
All that is left is +100 and -100 screen material - still playing with it all.
