CJ,
Deep drilling was done, not the assays. I can see from he latest exploration update that they have done them and plenty more.
My thinking was that these deep drill holes were a necessary evil to show that the mineralization continues to economic depths - even though everybody knows it goes to the center of the earth (hydrualic fracturing).
Unfortunately they take a long time to do. The deeper you drill, the slower you drill.
They are well out of the way now, and it sounds like things are progressing full steam ahead.
