[QUOTE="SneakyCuttlefish, post: 379208, member: 3340"] I wonder if you would be better off asking the gold guys in the gold prospecting section. Those blokes know their metals. My guess is massive form chalcopyrite. If you drag it across a white tile the streak should be greeny-black and it will become magnetic when heated. Best way to be absolutely sure is to send if off to SGS or another lab and have it essayed. Costs a couple hundred dollars but they send back a report with the full break down of all the elements and what concentrations they are. [/QUOTE]
