They have contracted a rig to drill for an approximate dollar per metre. They are telling you that they have 2.4 mill allocated to this drilling program. Where and what they drill will be constantly changing situation. When they finish the first hole, what they find will determine where they drill next. If they use up the 2.4 mill without finding the big one we are in trouble(just kidding). An example of this is noront. They had 400,000 allocated to this project which was enough to drill one hole. They have not even considered restricting the drilling because of further costs.
