"If this hole is close, they may be able to angle off of it in various directions, reducing the number of times they have to punch through 2000+ feet of rock."

What?  Maybe I misunderstood, but the mineralization should be around 300 feet below the surface, so I think they are having trouble getting below 300 feet.  And there were to be two holes, each of 1,000 feet.  If or when they get below 300 feet, there should be material worth sending to the lab.
