Here's a little item I found on another forum.
http://www.sciencenews.org/view/generic/id...onds_to_surface This thin slice of a kimberlite rock from northern Canada, seen through a microscope and in polarized light, shows colorful minerals caught up in magma that rose from deep within the Earth. Leonard |

Yeah very true and there is about 100 000 tons of alluvial material right on top of the pipe so one can start mining as soon as the Washing pans are set up. Takes about three days to set up.. Then once the loose gravel has been removed you step in with brooms and brush the rock clean this is where you find almost all the diamonds that was released out of the Kimberlite.. big paydays hahaha Then you start blasting and crushing.... I can smell the diesel fumes already The area is well known for the large stones, if you hear of a 200 ct stone found in Africa this is the area... Greetings. DD |
