Considering GRZ's cash on hand and equipment value, the market is already attributing a negative value for Brisas and the Choco property so why would the loss of a negative value affect the share price in anything other than a positive way?

GRZ has $105 million in cash and about $35 million in equipment either paid for or under construction. You can build a nice little gold mine almost anywhere in the world with that sort of seed money and there are lots of juniors sitting on ore bodies that they can't finance or get equipment to mine within a reasonable time who would be delighted to do a deal. GRZ hasn't got too much dilution with only around 55 million shares issued so that's $2.50 a share in value allowing zero for Brisas.

GRZ is trading for less than half that now.
