This has always been the main reason to be in this stock IMHO, i.e. the resource is likely to be much greater than the 2m or so ounces that are currently on the books. Remember Frank Barbara's famous report speculating at a 5m ounce resource...?
We need to find a viable way into production, most likely a JV of some kind with a producer. If that happens then this could be one of those stocks you just keep holding for years and years as the dividends roll in and the mine life keeps getting extended as more gold is found at depth.
