Ernio, if you read today's news release, many things have changed since 2013.

The PEA will incorporate a project configuration that includes updates to the resource estimation, mine plan, plant layout, and tailings and waste management facilities.

When compared to the January 23, 2013 Feasibility Study, the PEA incorporates changes to the mine plan, operating and capital costs, design improvements, updated metal pricing and USD:CAD currency exchange assumptions.

Therefore, it's my understanding that many sections of the document need to be updated.  It's not only a question of changing the numbers, you need to be able to explain how these numbers are possible and that usually takes a couple of hundred pages.
