Here are my thoughts about the delay:
* I think they knew there was a possibility of a delay on the Feasibility for quite awhile but were pushing hard to get it done.
* At the same time they were working on the revised Resource Estimate that will increase value significantly.
* At the same time they were attempting to get the silver included.
* Bearing in mind if the Feasibility were produced using the 2010 numbers it would be out-of-date even as it was released.
Maybe the Resource Estimate was starting to show much better numbers and it became obvious that the whole project would be significantly better if the new data from the new Resource Estimate (RE3) were included in the Feasibility and so the decision was taken to just take those extra months. They pulled in Jim Gray, who they have worked with in the past and who was familiar with the project and the historical data. They now have a team together who can complete the Resource Estimate and incorporate it into the Feasibility properly.
At the end of the day, (or month, or year,) we will have a much better project and more accurate project. . . and more valuable project.
