Yeah have been keeping a close eye on CXC too. Kicking myself I didnt buy a few months ago. Was in Bolivia in Jan when Evo Morales won the referendum and just got a little concerned he may nationlise San Bartolome one day. Thats all that stopped me. Seems cheap to me and like you said very leveraged.
Will look into those perth mint bars and coins. Just hard justifying paying $30/oz when ETPMAG is under $18/oz but I know long term bars and coins are safest.
