That's what I kind of thought. Just wanted a more experienced eye to look at it. Thanks.

For some reason I can't enlarge photos anymore on this site.You can always crush it up and pan it out.Also in some gold bearing areas arsenopyrite is a good sign for finding gold.

Dave, if you click on the photos on my computer, you get a box with loading circle going round and round in the center. If you wait, nothing happens - it never loads, but if you click right on the circle it blips a little, then up comes a huge magnified pic. Hope this helps.

P.s. - click the back button to return

Arsenopyrite will smell like sulphur -garlic when you crush it..the arsenopyrite I found was pretty black and heavy, would spark when hit with a hammer. Black streak on tile

if you have nitric acid put a drop on several pices .
The ones that look rounded not squared or sharp flat edges . I see some pyrite in the center sample shown . The first one Gould have small micro gold but would need to be fire tested to tell for sure . The nitric acid will melt what looks like possibly silver and turn it to a milky looking substance .

best way is to crush and pan , then fire assay.
