Personally, i never buy goldies based on EV/resource because they include a bunch of gold that may be uneconomical.
Prefer to buy based on DFS as the numbers are crunched by consultatns and you can properly evaluate the company's worth based on it.
Hopefully the cash position allows CVY to complete the DFS but i doubt it will last till 2013.
At this point we don't know what the exact capex and cash costs of this operation.
