hedge the lot

If Silver reached $45/ oz why wouldnt they hedge the total jorc that there is here, sure you may not get an additional upside but then again I would be happy to have $45 / oz in the bank less production cost say a net of $39/oz and leave the upside of the company to acquisitions and exploration . Bird in the hand....,
Even though these deposits have a 5 year mine life at $45/ oz that would be a company maker for CCU.
Plenty of options here to choose from.
