Na. I have a few but honestly it's hit and miss. The mining game is hard yakka despite the metal price there is so much to get a miner up and running. If u positive on gold might be better off buying the metal directly.
IMO the price has to go up. grades are going to get lower over time and expenses have to go up.
So figure what u buy now will definitely be worth a tonne more in 10years despite any world wide drivers like wars and other political instability.
