It is really difficult to guess--managment is non-committal on any expectations of the amount of resource to be converted from Inferred to M&I.
Keep in mind that GM is going back and lab testing 1000+ samples from Valardena that were originally measured by an unaccredited lab in Torreon. This accounts for the delay in the Valardena 43-101 until mid-1Q '12 (or later). I don't believe there is any concern about the reconfirmation but management just doesn't want to allow for any doubt about the authenticity of the results.
