I'm usually pretty good at telling them apart but I'm kinda baffled from this one I always go by the rule gold is spongebob yellow but this is that color but almost seems to shiny to be gold what do y'all think

If you are not checking color in full AND in shaded light then you need to do that. Pyrites and the like may have a shiny gold color in full light but the yellow disappears in shaded light......gold will still look like gold/yellow in color, no matter the lighting.

Good luck.

It sure looks like Gold under magnification but without seeing it in person, there is no way I can be sure. Pick a spot with a solid well formed piece of Gold or Pyrite and press a sharp punch, screw driver or tip of a knife blade into it. If it shatters or flakes, it is not Gold. If it dents but does not shatter or flake, then it is likely Gold.

and a 3rd thought...maybe it's both gold and pyrite (pyritic gold).
I've seen samples of pyritic gold, not certain what the proper way to test would be.

A better reason to crush and pan. Good idea to do some screening as well and pan each screen size after running a magnet over it.

It could be chalcopyrite. More of a yellow color
Than normal iron pyrite from the copper content but may also contain gold.. worth a crush and pan or fire assay
