Sudhir Khanna of "The Resource Indicator" makes some excellent points. Visit his website athttp://goldsheet.simplenet.com/tri_home.htm to review recent performance and issues, and learn about his newsletter. A couple of many v.good points from TRI:...The water and air action agglomerates the ash into little balls or "lapilli" and they fall to earth or to water (similar to hailstone formation). These are very common to all types of volcanoes. The difference here is the contained volcanic glass shards and the ilmenties with perovskite reaction rims. This is virtually exclusive to kimberlite pipes, especially in the quantity recovered by Marum. These ilmenites are also rare in northern Alberta and likely come from a more local volcanic source. Also, these ilmenites would not have survived transport of any great distance in the sedimentary or glacial environment as Mg-ilmenites are destroyed very quickly by physical and chemical alteration. Ashton reports ilmenites with high MgO and elevated Nb2O5 to be important because these grains are considered to be indicative of kimberlites or related intrusions. To date, although ilmenites have been discovered throughout Alberta, very few have a high MgO content. --- Also,Based on auger drilling, the area is known to have thin drift and therefore even a few indicator minerals in drift should be considered highly important. This is a very good point. Since there is so little OB, what's in that in terms of diamond indicators is highly significant. TRI made many other good observations. It's nice to have an interpreter who knows what he's talking about. ----- Marum has made real progress, and is proving their understanding of this field. I sure wish the markets were in better shape to receive this news, as well as make for a better operating environment. -j :>
