Good morning all. Well the geoscience forum has wrapped up for another year and after three days and four nights of socializing and geologizing Im like most still in recovery mode.
The Winspear talk lead off the diamond session and was well attended. The talk (like most at the forum) was a review of winspears activities over the past few years. In and of themselves you dont learn anything new at these talks (that would take a press release) but what you do get is a better feel for the project. It helps put things in context and may remind you of things you forgot.
The dyke they drilled is a little east of the green clay area, it has a fairly shallow dip 10-20 degrees to the west and sits under about six meters of glacial till at its shallowist point. Thye plan on taking two samples from it for processing, this year.
The kimberlite breccia they found at CL186 they feel is a very high volatile breccia, ie it came in very fast. This means it had to vent somewhere. Also it contains sandstones and microfossils so it most have got these from somewhere, the trick is to find where it surfaced. ( at the diavik -aber talk they talked of fossils wood and clay from surface ending up 100s of meters down into the pipes) Alot of pipes when they come in have pulses the kimberlite comes to surface then as gas etc escape collapse back down the pipe then another pulse comes in. So that is how surface material ends up so deep into the pipe. It really is amazing to see a piece of charded wood encased in a kimberlite sample. SO all the evidence suggests the WSP kimberlite breccia should come to surface somewhere it is a matter of finding out where.
The new boulder train they found is of course most interesting and seems to be good strong and straight so hopefully it will lead back to a pipe under snap. The train runs along the edge of the indicator mineral train or close to it so the target may have got missed first round of drilling snap because they were drilling targets more towards the center of the trains.
Scale is always important to remember when looking at the maps etc. On the tundra you could walk a few feet away from one of these boulders and not see it with drilling you could drill a few feet away from a pipe and not see any indication that a pipe exists so on a map like on the wsp web site it is a little decieving. On the map it may look like an area has been well covered but when you blow it up and look at the same area in the field there is lots of room for those pipes and new discovers to be hiding.
A trick I use to use to impress this fact to juniors was to take a map or airphoto of the area, overlay a milar sheet with typical size deposits on it which would be a dot, line or small shaded area and move it around. The large area you are exploring vs the dot you are looking for. It gives them the idea that finding mines is not easy.
Also one has to bear in mind that the model or assumptions you are using could be wrong. Pipes are usually in depressions etc but not necessarily so, Maybe the glacier dumped more till in the area so the pipe is sitting under a mound of glacial debre rather then a depression. You just never know.
OK so that was the winspear talk, they are getting ready for the winter drill program and exploration season.
Diaviks talk was also good and they are in the process of designing a dyke system to put around their pipes and working on mine plans etc.
Thats about it Ill have a few other posts about this and some related topics to make latter on.
Regards Walt
