JORC code is a standard of reporting drill results that mining companies are required to comply with.
You will find that EXT's drill reports are all JORC compliant and compiled by a "competent person" as the JORC code requires.
So as long as the drill results meet the JORC standard they can be included in the DFS but they will be classified as "inferred" or "indicated" etc.
A really good document to see how these classifications are arrived at can be found at http://www.riotinto.com/documents/ReportsPublications/Issue_80_-_In_the_Opinion_of_a_Competent_Person.pdf
In any case, the resource statement due out in Q3 (my guess is late July or early August) will give us a very good idea of how much of the resource has been defined.
We should see the "indicated" figure increase thanks to infill drilling but we should also see the "inferred" figure dramatically increase thanks to exploratory drilling of all those rigs.
