Still alot of selling going on-- they must not have confidence that we will see core results anytime soon.

Joe: Results of the drill core should take approx. 4 weeks. Bernard Rowe, geologist, has just arrived on the property from Melbourne Australia and with Mr. Dearn Lee, mineralogist, will carefully log the core before it leaves the property. Once it arrives in the Ashton Laboratories in Perth Australia the core will go through five different tests. 1. Age dating 2. Thin section for mineralogy 3. Proton microprobe analysis to determine the depth and termperature of formation of indicator minerals and thus the capacity of the pipe to contain economic diamonds (Nickel Pyrope Thermometry) 4. Macro diamond analysis 5. All core is crushed for micro diamond analys As to the different type of kimberlite encountered: The tuffaceous kimberlite is the material that ejected from the volcanic eruption and settled back into the crater and compacted. Both the kimberlite breccia and breccia with lapilli are similar. They are loosely consolidated angular kimberlite mineral fragments. The lapilli essentially indicates the fragment sizes of kimberlite and other associated minerals within the rock formation. In our case upto 5cm. But thats only important to geologists. The only thing that the rest of us should be aware of is the three different phases of a pipe. You can compare a kimberlite pipe to a champagne glass. The crater phase is where you would find the tuffaceous kimberlite(151m-176) and sediments that accumulated on top over the millions of years (0m-151m). This would be the top part of the glass that holds the champagne. This phase has the largest volume of material but is quite often eroded away. The crater phase of the Kassama is intact. The diatreme phase would be the stem of the glass. This can extend downwards to two kilometers. Then there is the root or feeder phase. Being so deep this phase is seldom encountered. One theory is that the deeper you go the less diamonds you'll find, so the root phase is usually the least important. Each phase can can contain diamonds and is measured and analysed differently. In our case the kimberlite breccia or the breccia with lapilli could be the beginning of the diatreme phase. It is always difficult to determine the transition of phases since there isn't a definite line where the change takes place. I'll put up a diagram on our site today for you to see. George
