Treasure hunting, more crystals and fluorite, Colorado 2018 - what do gold dirt rocks look like?

No music in this one, there is a magical blue crystal cave however with a little pond in it and hundreds of blue and clear crystals. Its just for fun, the majority of the video is learning, talking and sharing on rocks and minerals, treasure hunting and rock hounding. I could use some input on if this looks like a good area to be hunting for gold. The quartz doesn't look right to me, for gold, but the red dirt and orange and black on the rocks?
