[{"type":"text","content":"\n \n 8 July 2008\n\n Karelian Diamond Resources plc \n\n (\"Karelian Diamond Resources\" or the \"Company\") \n\n MICRO-DIAMOND RESULTS PROVIDE CONCLUSIVE EVIDENCE \n\n THAT SEITAPERÄ KIMBERLITE PIPE IS DIAMONDIFEROUS \n\n * 67 diamonds recovered from 100 kg Seitaperä kimberlite sample\n \n * Diamond population includes 61 micro-diamonds and six macro-diamonds\n \n * Stones show good colour characteristics and high level of preservation\n \n * Good access and infrastructure enhance overall status of project\n \nKarelian Diamond Resources (AIM:KDR) is pleased to announce highly positive\nresults from micro-diamond analysis of the 100 kg sample from its Seitaperä\nkimberlite in Finland. In total 67 diamonds were discovered in the sample, of\nwhich 61 were micro-diamonds and the remainder were macro-diamonds, the largest\nof which measured 0.63 mm by 0.48 mm by 0.38 mm. The analysis was carried out\nby SGS Lakefield Research Limited (\"SGS-Lakefield\") in Canada.\n\nThe diamond colour is largely white (42 per cent) or off-white (52 per cent)\nwith the remainder grey. In addition, the micro-diamonds exhibit high levels of\npreservation, greater than 75 per cent in the case of 91 per cent of the\ndiamonds measured.\n\nThe material analysed consisted of 100.20 kg of drill core taken from holes\nSP10 & SP10A which were drilled in March 2008. This material contained zones of\nup to 50 per cent mantle xenoliths, but the overall content of mantle material\nin the sample was estimated at about 20 per cent. Micro-diamond counts from the\nmantle-rich intersections alone could potentially be significantly higher.\n\nThe micro-diamond size distribution is shown in the table below:\n\nSize Fraction No. of Stones \n \n+300 µm* 7 \n \n+212 -299 µm* 4 \n \n+150 -211 µm* 28 \n \n+105 -149 µm* 28 \n \n \n \nTotal 67 \n \n*1000 µm = 1 millimetre \n\nThe total diamond population included six macro-diamonds, defined as crystals\nwith one dimension in excess of 0.5 mm (500 µm).
