gold in shale is not common but possible..
Years ago an old hard rock miner showed us some gold in gray  / black shale just like what you have in the picture. He said he picked it up in the Chilliwack lake area.  Think he said it was in a military area so couldn't mine it. Probably would have gotten in trouble for even being there..
 I have a witness  to what what he said and showed us. Never ever heard of such a thing before, and have never seen anything like it since..
I don't know if what you have is gold or not, could crush it and pan it..

Most likely sulphides as they are common  in shales and cold water deposits as replacements of carbon materials. Gold CAN come out of solution onto carbon in shale but the circumstances  are very rare. As others have said take a small piece and place it on an anvil like base and give it a  tap with a hammer. Sulphides will crush - gold will flatten. Even if it is sulphide it is darned cool. Watch for fossils of sulphides where the sulphide was the fossil making mineral. Makes some very interesting specimens.
What the heck - lets just keep mixin' stuff together till it blows up or smells REALLY bad!
