Directional drilling is used to take multiple cuts from a mother hole. That hope will have multiple branches either aimed at different compass points and or different angles. This eliminates the need to redrill the top few hundred meters of waste rock. I'm guessing a Devico tool will be used, this takes a small core sample when the cut is started , that is quite important in exploration holes, normal wedging destroys 1.5 to 3 meters of the rock depending what types of wedging is done to get the hole deviated to a new target. The tool used will only start the hole on a new trajectory and then it is back to normal coring to complete that cut. Geophysical surveys will tell them in which direction to aim for to do the next cut.
