I dont´think that they will drill more holes. (see the press release beyond)

I also talked to Investor Relations about this point in June 08 and that was the resonse:

The focus is on getting the main zone into production. Once the infill drilling is complete (these last 7 holes) on the main zone, there will be no need of any more drilling on the main zone. The size of the ore body and grade has been identified well enough. The drilling on the Red Hill Zone and eventually the Discovery Zone is for blue sky purposes. This will simply add additional tonnage that can be mined at a later date. The plan is to drill enough on the Red Hill Zone to identify the size of the ore body and to give an indicated resource amount. Once this is done, then the focus would be to do the same on the Discovery Zone.

Press Relase from June 08:

The program consisted of 52 diamond drill holes totalling 15,646 metres, and was designed to upgrade inferred resources to the indicated category. The infill drill program originally contemplated a 40 hole program, but was augmented to investigate previously unidentified mineralized areas, especially along the northern and eastern sectors of the deposit.
