Good to hear from you Chuck, always like it when you appear. Too bad about the hockey season, more time to share ideas and do research, I guess. Good find on the Philip James & Associates report. Fortunately for me, I only came on the diamond scene with Winspear, getting in at .44. Boy, those were the days! I've did some digging, with some stuff posted below. I will add Dentonia and Kettle to my list as well. Thanks! Keep'em comming!! Rob Friedland's Peregrine Diamonds is a private company, but worth knowing of. pdiam.com Peregrine Diamonds Ltd. is a unique diamond and mineral exploration company. Peregrine has exclusive use of one of BHP Billiton's revolutionary Falcon™ airborne gravity gradiometer systems. This exclusivity is for a minimum of 52,500 line kilometres per annum of Falcon capacity for all of North, Central, and South America. Falcon is a highly sophisticated system capable of direct mineral occurrence detection. "Kimberlitic intrusions are the hosts for diamond deposits and these intrusions are generally small in size, hundreds of meters in diameter, but complex in that there can be multiple intrusions. Falcon™ technology is particularly effective in the search for kimberlites in that although some kimberlites have a high magnetic susceptibility, most will be composed of low density material and therefore exhibit a density contrast with the local county rock. Falcon™ is effective because it measures both density contrasts and magnetic susceptibility. A significant number of anomalies were found on both blocks which will be drilled this year. Peregrine is continuing its search for diamonds in the NWT of Canada and is considering expanding the search areas in the Eastern Arctic of Canada." Dentonia's [dta.v] site was of interest, some tidbits below. dentonia.net Detailed mineralogical examination of diamonds from the DO-27 pipe revealed that approximately 35% were of the nitrogen-free, type IIa variety [Davies, Griffin et al., 1998]. At least 25% of diamonds with mineral inclusions, all of the nitrogen-free variety, host inclusions of very high-pressure minerals, including ferro-periclase and Mgperovskite. The presence of abundant nitrogen-free diamonds in the DO-27 pipe is promising, as deposits with relatively high abundances of nitrogen-free diamonds reportedly hosts very large (over 100 cts) diamonds [E. Sobolev, 1984,; Kaminsky et al., 1988] In order to assess whether further studies should be performed on the DO27 pipe, we performed a serious of experiments to quantitatively determine the concentrations of nitrogen and hydrogen structural impurities in diamonds extracted from different facies of the DO-27 pipe. The main objectives of this analysis were to identify nitrogen-free diamonds and to correlate the results of the study with available data on diamonds from deposits in Siberia, the Arkhangelsk region, South Africa, Venezuela and Brazil. In total, 201 diamond grains were selected for analysis from 305 diamonds submitted from the DO-27 kimberlite pipe. Kettle Rivers [krr.v] web site is greenwood-hub.com Interesting story perhaps in the making. greenwood-hub.com I want to understand the pipes in this survey, but it will have to wait. LMBF

Everyone said KCOTT effed up the tests. What is a mystery is why they decided to do the tests in the 1st place. Why 20,000 tons? Well they must have had some geochem evidence. Geochems rarely lie. One group of tests I have always suspected it the 1970 Cominco tests on the K-lites on Somerset Island. They tested low, by a portable sortex (X-Ray sorter) machine. But no one uses just a sortex to recover diamonds. Only 20% of diamonds fluoresce. (Russian data) Most plants use DMZ, grease, flotation, gravity AND sortex altogether. Were the Cominco tests invalid in using only sortex? Was the sortex machine set right? was it well run? Russians who developed Sortex tell me that it takes a bit of setup. Were their Stateline tests of the Co-Wy brdr. also badly done around the same era? R. Mitchell, a former geoprof who worked on the Somerset K-Lites said the diatremes, incidentally found visually, were bad chem and their chem predicted their low grade. High calcium/aluminum etc. I am not sure about that. 20-20 hind site? I would not want to Tli Kwi Cho again, regardless of the doubt field presented. What we never hear about that Griffin and Ryan discovered, about nickel thermometry and its efficacy in determining grade without pyrope, we never hear from CDN explorationists. Some say they do it, but although we hear about G-10 levels they never say boo about NT. I think they are BSing. They don't know squat about it, or its interpretation. Would that they did know more about geochem, as it would save a lot of testing. Sobolev found dozens of K-Lites miles up ice by testing pyrope for chem only. Apparently it works. And he tested few pyropes and found many K-lites. Exactly where he said he would find them to the mile. Peripherally, R. Mitchell did a lot of study at the High Pressure Physics Institure in Moscow for years. He formed his own geobarythermometry ideas from that research. The Russians led the field of Chem geusswork for many years. They based their work on Australian curves developed in the 1950's which guided W J Atkinson, in his investigations of the Namibian Dykes off the coast of africa in the 1970's. This work did much to confirm continental drift. Later Gurney, thought by many to be a pack leader in pyrope analysis expanded on the Russian work. Still later when the Argyle K-lite was found to be a 695 carat per hundred ton wonder, Griffin and Ryan in Kangaroo Land had done nickel temperature, by proton probe, not electron probe and predicted its grade to the carat, before the bulk sample had been done and the grade confirmed. Chemistry anyone? EC<:-}
