Having trouble identifying this rock
I am a complete noob at this.
I live in Arizona and explore abandon mines all over the state. YES I take great precautions doing this. Along the way i pick up rocks from tailings and various locations around these mine sites.
So I was at this mine http://www.mindat.org/loc-3402.html
we were exploring a dry creek in the area and i found a interesting rock. Ive been trying to use various tools to identify it and im just not sure..
I have attached the pic..
Its quite heavy. About 1 1/2" long. Is not magnetic. Is silver/dark grey. Extremely metallic looking shiny crystals. Does not glow under black light.
Any suggestion would be awesome..
