It's only 3500 metres of drilling.

They really can't go ham on it and drill 40,000 metres in several areas?

The mineralization in the Schaft Creek deposit is open in several directions and additional drilling is required to test the extension of the mineralization in these directions. 

The Schaft Creek Project covers a 12km-long mineralized trend that hosts the Discovery and LaCasse zones located between 1.5 to 3.0km north of the Schaft Creek deposit. Limited diamond drilling intersected significant intervals of porphyry style Cu-Mo-Au-Ag mineralization that is open in several directions. Several copper showings have been found north of the Discovery/LaCasse area and south of the Schaft Creek deposit. The exploration potential of the 12km-long trend is considered significant with potential to host additional porphyry style copper mineralization.
