Thanks, Arkcon for your time in replying. This is a gel he's already broken the neckseal on, so it would be hard to resell. He's tried.
He showed me the paperwork on it from the old manufacturer he got it from way back when. It has close to 1 troy oz of gold in it to be recovered.
As I said earlier, I'm not afraid of the cyanide, as it can be neutralized with NaOCl, same as has been done for centuries of laboratory types such as you guys and gals are.
As this is old stock, his cost basis is so low, he would owe capital gains on it by selling it outright. He wants to keep the gold, and wants me to cast it for him into something his wife can wear as a Christmas present. We are kicking around some designs, but hasn't settled on anything until I get the gold out, and can weigh it for him to make his final choice.
Thanks again for the responses. I'm still looking for help here, guys & gals.
