My first thought on seeing that rock was bornite, but hopefully some others on here have some more opinions. If you have trouble getting an ID here then you could ask the several geologists at http://www.mindat.org/msgboard-11.html (its free to sign up, no I dont work there or anything I just find the site useful).

peacock ore? traces of copper,silver,zinc,......could you post some still pictures using soft light like a 50 watt bulb looks a little to "glittery" to be gold.

I am thinking Chalcopyrite with Pyrite.
From what I can tell, good close up pictures would be better.

If you think you have gold a quick streak test should settle the matter.
Rub it against a unglazed porcelain and see what colour it produces.
Chalcopyrite would have a greenish Black streak.

Here is a close up of the smaller sample in the vid. Its been dried off and is out of the sun so the sparkle is gone. I would put a close up of the bigger piece but the digital camera is dead. FOr this rock I used my scanner but the other piece is to big.
