Once the process of getting release approved and out starts their are a lot of people who see pieces of it and a casual comment in passing from someone is entirely possible especially as it wasn't specific in nature.

Some are expecting spectacular news while most of us would be satisfied if they just obtained enough information to target potential. 4 Drill holes isn't enough to do more than gain enough information to justify full exploration. Mind you they could get lucky and all it will take is good intercept in one hole to start ball rolling.
