I have a metallic mineral chunk, but what is it?

0 votes

This specimen is heavy, but I believe it is a hardness of about 4-5. It did not melt when I quickly put a torch with MAP gas. When I put an ice cube on top the ice melted super fast. If anyone can help me identify it, I would be forever grateful. Thanks.

Is it magnetic? Can you scrape a small amount off and see if it reacts with acid? That can be dangerous, so make sure you use proper eye protection, skin protection and do it in a well-ventilated space. Do you know where it was found? We need a little more information.

Visually it appears likely to be galena, but as weasel said, please provide some additional info. Also please post some additional pictures, including close-ups.
