Hello Tomato
A few of my own "musings".
1. I did not start to post on SI until April I believe. I am not sure what the source of the January reference is?
2. I hope you are not "putting your money" on my, or anyones musings on the net.
3. As I recall you did seek my advise several times on the SUF thread and in fact did end up investing. I trust you have not been disapointed with my advise.
4. I may be wrong, but I do not believe that I ever suggested that the downice garnets and diamonds came from any source other than Snap Lake or the target that was then to the northeast and just beyond Snap Lake. I believe that target turned out to be 186.
5. I believe one of WSP's announcements referred to heat discolouration of the granite cap on 186. From my research and through my sources we took that to imply that heat had been retained during the emplacement of 186, a condition that statistically, is not condisive to diamond preservation. Rather, it is suggestive of a root zone that has not had the opportunity to vent, and therefore cool, that the upper diatrem of a pipe otherwise would.
6. The age of 70 million years is completely irrelevant to whether there has been severe errosion or not. Kimberlite is soft and is easily erroded. In fact if "blue ground" is left exposed to the air for a few months, it literally falls apart. A technique the early miners of SA learned when they had difficulty hand mucking the harder blue ground after breaking through the yellow ground. Errosion of an area has to do with three factors: 1. mechanical forces (ice, water, wind), 2. environmental forces (freez/ thaw & sun), and 3. host rock hardness. These factors can vary dramatically within local areas. The SA Premier pipe was emplaced in the Middle Proterozoic era (1.1-1.25 billion years ago and was only moderatly erroded compared to other SA pipes like Kimberly emplaced in the Middle & Upper Cretaceous 65-100 million years ago and severely erroded. That is why the Orange River and Namibian coast has been such a rich source of aluvial and fluvial diamonds. Most Angolan pipes were emplaced in the Lower Cretaceous 115-135 million years ago and in many cases are completely preserved including the tuff rings. Comparing 186 to the Camsell Lake pipe for errosion comparison and thereby drawing any age conclusions is an interesting exercise but not very relevant.
7. I have no "geological credentials" as I have repeated several times.
8. Diamonds not from 186 because they are 600 meters (1,968 feet) to the southeast! That is not even half a mile away. There have been several ice ages here and ice direction has altered by approx. 30 degrees in those that can be traced. When the ice melts (Lake McConnel) water flow patterns are completely unpredictable, torential and dependent on ice daming, esker dams, and newly exposed geological relief water can run in any direction carying everything with it.
I am not in any contest here Tomato. I could honestly care less who you believe. I have posted here to help some people with whom I have carried out an enjoyable correspondence. The fact that you can lurk and benefit or scoff is your prerogative but I d not need to waste any more time responding.
I have previously suggested, if you or anybody do not like what you read please feel free to exercise your options and just skip on by.
