Hello again. Sorry to keep posting in this topic but I put the samples under a 60x microscope and this is what I got. 

Yes, unfortunately the flakes move easily.

Otherwise, I tried smooshing a nail into the rock and it made a hole in it, and the largest flakes from the pan leave a really yellow mark behind when I try to scratch something with them. That's all I could try at the time. 

This is the best picture I got

Thanks. I smashed a very little sample I had and all this shiny little flakes appeared along with the quartz.

Hello, I was in patagonia last week and found a quartz on the mountains. I broke it down and this shiny mineral appeared inside. I would like to know if this pieces have some gold in it or if its just chalcopyrite (since I'm relatively new to prospecting). 

Thanks.
