The main problem is that management has not "managed" this news release very well. First they build up expectations beyond what is called for, then they mismanage the actual release.
Because the way the results were stated, the grades shown are fairly low, particularly since the ore has to be shipped over 100km to the mill. Building a concentrator at Barry would make sense but is quite expensive. It probably would have been better to reduce the M&I ounzes but show better grades. Not knowing the structure of the deposit, I don't know whether this was actually an option.
I think there is still a good upside, particularly if they find some more higher grade deposits. Right now the total oz are about 1.5million but the cost of extracting the Barry oz is fairly high.
