Ann: Exploration and Drilling Update, page-81

In regards to those scissor holes I drew I just noticed the one on the left is bit too short and if MAG drills them that hole will go further 200-300m in order to test the contact zone between the monzodiorite and the diorite/porphyry intrusions.
The only reason why MAG could shy away from such holes will be the cost as both holes will be very deep and therefore expensive. Adam may prefer more shallower holes and test along strike in order to define best spot where he will send couple of deep harpoons later.

Each approach has plusses and minuses and no one knows what is the best approach. Geos build theories based on data and then change/adjust those theories in light of new data generated by more scans and drilling. However, drilling data is the one that provides the most valuable indictors as it offers (especially diamond core) visuals, orientation, chemical composition at depth, stratigraphy etc..
