Any bit of bad news at the moment and individual PM stocks tank. Last week it was Jaguar Mining and this week Guyana. Over they seem to be a good long term bet with manageable debt and cash of over $65 million, but one bad quarter that has been explained and actions taken to make sure it is not repeated, and the stock just dives as below. I just hope that when the good news comes in that they rise by the same or more?
