[QUOTE="XLOOX, post: 632608, member: 16174"] ...and 10 :1 diluted brick acid ( hydrochloric) will dissolve most of the rest of the non valuable nonmagnetic silver coloured metals.... If it survives caustic and acid and is non magnetic but still soft enough to mark with a knife then it is interesting enough to get XRF done at your local gold buyer, but their charge will be more than that lot is worth so would only do for interest or if you think there is lots more around [/QUOTE]
