Morn'n Steve:Russett please explain to me what a G-11 G-12 are? I am not a geologist but have done diamond exploration before and have never heard of G-12s so please explain! Pyrope garnets are classified by their elemental composition into various classes,...the G scale(and there is a J scale as well). Whatever volcanic crap that blew up through the area underground where diamonds formed (carbon from used to be living things + high pressure + high temperature = diamonds), carried the diamonds plus a lot more of these pyrope garnets up closer to the surface of the earth. The pyrope garnets form in much greater quantities than the diamonds, indeed the diamonds likely crystallized around the pyrope garnets. Anyways, these pyrope garnets have different elemental compositions of Chromium, Magnesium, Iron and Calcium etc., depending on what the pressure and temperature and earth conditions were where they were formed. Turns out that the higher the G number of the garnets,...the more likely these garnets were held under the same conditions (temp, pressure and elemental composition of environment) that form high value diamonds. It's not always the case, but it's a good guide. Fact is they keep changing the guidelines as they find new diamond deposits, with new pyrope garnet (and other indicator mineral compositions). Now back to Winspear. According to RT (with many witnesses around) Snap Lake had the best pyrope garnet signature that has ever been found anywhere in the world. Far better than Hilltop, Ekati and Diavik, South Africa, Angola etc., etc., having not just G9's and G10's but G11's and G12's. Who am I to argue?you guys keep going on about wsp and there big tonnage. But the truth is, it is not that great. Minumim mining widths are 10 feet 2.5 meters is 7.5 feet so 1/4 of what you take out of the ground is going to be worth nothing. You guys also talk about 40 million tonnes plus what a joke. LOL. I do agree if the pipe is found it will be very interesting and I will be watching. I am not talking big tonnage as some are. I believe we have 15 million tonnes indicated, and 5-10 million should move into a reserve category by August of 1999 when bulk samples and drill cores are analyzed by the current program. Current mining guidelines I am familiar with say 8 feet can be shaft mined, not 10, and the shaft for initial underground work will mine a dyke that appears to be 3 - 4.5 meters high for at least a kilometer down dip and perhaps 100 meters along strike, then it narrows a bit, over the other 2 kilometer of strike. MRDI says all we need for a very economic mine is 1.4 million tonnes (10 year mine life). It is clear from your comments that Snap Lake is very misunderstood by many people. We don't need a pipe, although I agree, that would be interesting. Adequate tonnage is already proven. Grade in the area to be mined is basically proven as well. All we await is confirmation of those amazing valuations of $300 US/carat. This is all we have left to argue about.Maybe Aber didn't want to be involved in this and I see where they are coming from. I agree,...I wish they had of taken the $50 million Winspear offered them for their share of Snap, and then the shareholders of each company could ignore each other. russett
