Teevee, I thought this might be interesting. I took it off the MMU thread. The answer was to a question about Alberta but I believe that the comments about Orapa may be relevant to the situation at Snap Lake, particularly about the kimberlite lying between the pipes. Take the case of Orapa, one of DeBeer's crown jewels. The 1.2 by 1.0 km pit contains two kimberlite pipes and two kimberlitic pyroclastic layered deposits preserved between the small pipes. The pipe material is easy to identify, the pyroclastic is almost impossible to identify without laboratory assistance. So what? The grade of the pyroclastic layered material is ten times the grade of the pipe material. It would be possible, even easy, to drill into the middle of an Orapa type of exploration target and walk away from it without knowing it was a kimberlitic, high grade, massive tonnage, layered diamond deposit.
