[QUOTE="Guest, post: 68299"] Looks like arsenopyrite. Be careful of this if you are crushing it. It is basically arsenic. You are a long time dead with this. The only proven way to recover gold from this type of ore is roasting in a reverberatory furnace then using a halox (chlorine) method to put the gold into solution. Then you have to precipitate it out with a zinc process or electroplate the gold in an electrowinning set up. Way too hard for the small time prospector. [/QUOTE]
