Gord, winspear.com winspear.com Another term for cone sheet is ring dyke. Imagine a circular dyke, 5 kilometers in diameter, dipping inwards, towards the feeder/blind pipe at a depth of about 700 meters. The top figure shows the indicator mineral train south east of Snap Lake. The width of the train approximates the diameter of the circular ring dyke where it subcrops. The second figure shows a cross section through a portion of the ring dyke and illustratres its dip towards the apex where we all hope the top of a monster blind pipe will be found. I would think that it would take one heck of a magmatic event to inject over 120 million tonnes of orangeite into a cone shaped bowl with a diameter of 5 kilometers and an average thickness of 2.6 meters. Just think of the energy it must have taken to lift a cone shaped plug of country rock 5 kilometers accross and over 1000 meters deep at the apex, about 2.6 meters to rapidly inject all that highly diamondiferous magma!!!I hope this helps visualize the monster at Snap Lake aka "diamond discovery of the century" to cite Dr. Bob. regards, teevee

You standark Kimberlite Pipe model is something like a carrot it starts of small at the bottom and as it comes to surface it widens out. The theory of why they are this shape is gas coming up from the mantle expands as the pressure releases. Something akin to releasing an air bubble at the bottom of the ocean as it rises it grows in size. Alot of pipes down at the root zone have dykes and sills around them. A blind pipe never makes it to surface for one reason or another. Imagine a pipe starting to come up and then it hits a pre existing area of weakness, maybe an existing fracture in the earths crust so it and the kimberlite follow this new path of least risistance. Thus the dyke may lead back to the pipe which feed it. The kimberlite material in the snap dyke had to come from somewhere so it has a feeder and that feeder could easily be a blind pipe. What size the pipe or feeder is or could be is anyones case. Drilling will tell. As for the other train and drill targets Cl25etc I believe they hit pipes which weren't very diamondiferous but they believe there may be other as yet undiscovered pipes along the train because the indicators indicated better pipes they they so far found. If you have a train which starts at one pipe then passes over others, the indicators from the various pipes get all mixed up and you can have a devil of a time finding the good pipe. I believe it is aber who found a great indicator train but have never been able to find the pipe it originated from. In exploration luck often plays as important a role as skill and sometimes it can baffle people for years. Pipes usually occure in clusters and that is what makes the hilltop property so interesting, they have a number of targets there to test and the indicators are reported to look good. If WSP did find a pipe with the grade of the dyke, that would be very interesting. regards Walt
