<br />COLO. TECH. CENTER <br />CONTID <br /> <br />I did bring along the maps and diagrams <br />if that would help, of the Colo. Tech. <br />Center showing our various categories, <br />and I can put that up if that would help. <br />Dr. Robinson titled the map in discussion <br />as: The Index Map of Location of Drill <br />Holes in the Louisville Lafayette Area. <br />The City of Louisville is approximately <br />this junction. <br />This index map shows all the holes that <br />Robinson & Assoc. have drilled and logged <br />in the Boulder Weld County field. <br />These are ones we did on Paclamar Farm, <br />these are a series we did around Lafayette, <br />and these are the holes that we specifi- <br />cally drilled for the CTC. <br />This is called a simplified geologie log <br />of those drill holes in the Louisville- <br />Lafayette, Boulder County and as we have <br />indicated the conditions that we have <br />logged in this drilling hole. I might <br />mention that the first part of the hole <br />we drill by rotary methods, we just get <br />chips out of the hole. We go down some- <br />where around 20 to 40 feet above where <br />we anticipate the mine to be, change <br />our drilling method, put on a diamond core <br />bit and actually take a rock column; dig <br />a core out of the hole so that we can see <br />the condition of the rock and observe it, <br />a matter of fact is that they are all in <br />storage and available, and as far as I <br />know the CGS has not come out to look at <br />them. We have always had this opened <br />and available, expressed our willingness <br />to allow them to examine any of the core, <br />but as far as I know only other consul- <br />tants have ever come out and talked to <br />us about these cores. CGS has not felt <br />that it was apparently worth while. <br />The upper yellow part, the general sand <br />stone shale sequence, we have indicated <br />in those holes where we have found fractures <br />in the roof. You have an open hole where <br />the mine is left, the coal is taken out <br />and the opening is left. When the mine <br />is abandoned something is going to happen. <br />The opening may stand forever, as in some <br />holes, in other cases is has actually <br />caved in and totally calapsed, but you can <br />see what is happening above; what is happening <br /> <br />8. <br />
