Author: jspec -- Date:1999-02-28 13:26:08 Subject: North Shore by Northwest Regarding your question,WillP, about the north shore possibilities, I have been scouring through data readily available.'Prospector'Walt has made suggestions in that'direction'.He considers LMN-10 and O-11 as prime areas to look for valleys like the one on the NW peninsula. Looking at the MAP-we all seem to take frequent recourse to such a gaze-,and not being on the ground(for which I am grateful,considering the low temperatures),I would like to see effort expended from further drilling in the NShore oval to westward ho to a NW thrust toward N-11. The westward exploration from L-12,13 would cover the area north of NWpen,while northwestward toward the long finger lake(obviously a large valley) to find land based valleys would be a worthwhile endeavor. For readers wondering why the emphasis on valleys, the peninsula open pit prospect is in a valley,and a valley is a good place to find the kimberlite dyke with less overburden. Not being a geologist and not having contact with Winspear, I may not be reading comments on the north shore aright. This puts it up for input by others pro or con. Another matter of interest to me is that of the two magnetic lows. Looking at the MAP again and considering the supposed location of the mag lows(around the border between M-18,19 and L-18,19--possibly L-17,grid 16 less likely IMO of another observer of WSP's mag map--it comes to mind that the view of the company's geologists that the lows are likely the feeder pipe(s) is a great call. Howso? They are well centered on the diagonal down-dip with good values on both sides of the down-dip to the NW on one side and to the S and SE on the other side. What do I mean? That the pipe slung or flung out kimberlite in all directions. Call you what you wish,it looks to me like a sheet,dyke,sill with no,up till now,misses of significance. I forgot to note the great values of the NS drill holes-a normalized count of 1136 diamonds/1000 kg. Hope this stimulates discussion while we await news from the current program.

Given the 100 metre depth at hole 98-15 and a 15 degree incline, one would expect the "outcrop" had it occurred to be near the boundary of L10/11. I wish I had the depth of 98-19. Acting without same, however...I think that M11/12 are prime targets to be drilled as well. All of this leads toward the inevitable N10/11 and O11, as you suggest. The fact that there is no outcrop...does the dyke just peter out...or does the slope level off near surface...and run for some distance? A pleasant thought? The immediate drilling will be to find a suitable bulk sample area...and so the drilling may be a bit farther afield from L12/13 than one would otherwise suspect. The grid squares you suggest are probably higher on the priority list as a result. In fact...my first hole might have been in M10 just to settle an issue once and for all. I'm not a big 'find the pipe fan'...any more at least. However, I'm still an L17 booster. :-) Finally...for those not expecting news until the third quarter. Remember that drilling these holes goes pretty quickly. Basically a day or less per hole...not counting mobilization, etc. There could be a release any time...with serious impact on land based tonnage. (I think a bunch of misses would have little adverse impact in the M10 area...few have considered the possibility in that area.) I would think the addition of an extra 5 or more million tonnes on land to be of 'material significance'. How say the rest of you? :-) WillP ------------------------------------------------------------------------ TopReply Author: jspec -- Date:1999-02-28 18:09:45 Subject: Feeder Pipe(s): Smoke or Fire Feeder pipes seem to captivate some on other forums. Any reality to the possibility? If there,how big? If found will the pipe responsible for the dyke on NW peninsula and its extensions be a depleted resource having spewed out 10/20/50 or even 100 million tons or more of kimberlite? For feeder pipe enthusiasts this is a possibility to consider. The so far isolated appearances of a second layer of kimberlite may suggest an alternative to the palm tree hypothesis presented to date. If it(second layer) had its origin in another pipe--two mag lows are present in same general region--then this pipe could have significant tonnage possibilities. I am not suggesting that two,or even one for that matter exist; merely it is a matter to ponder for those who like feeder speculation thoughts. As for me I am basically an empiricist. If there is or are feeder pipe(s), GREAT. If not,we have a lot going for us without a feeder pipe or two. Just a musing for the feeder pipe adherents--and others. Regards, jspec
