Ah yes Brazil, the BIG mystery.
I know this board is for discussion of Canadian diamond exploration, but I would like to provide a link to a George Read report on the Canabrava Project in Brazil. This report was published by Read in April 2002 In his capacity as consultant (George Read Consulting). Subsequently he took over as boss of CNB in June.
This report has importance in showing his talent/expertise in the field of Diamond exploration, and reflects on the prospects of several Canadian listed companies operating in the area and their prospects of solving the mystery leading to an operating diamond mine in Brazil, specifically Minais Gerais state where the Canabrava project is located.
The report is large, takes a few minutes to download but provides a great deal of information on the history of the project and its problems and potential. Educational to say the least.
From my very limited understanding of geology it appears to me the problem of locating the diamondiferous kimberlites that are the source of the extremely large/valuable diamonds that have been located in rivers, etc. according to Read is the inability to discern between "true" kimberlite and diamond barren kamafugite pipes which are very numerous in the area. My understanding is Read believes he may have determined the primary indicator to eliminate some of this problem.
If someone does care to download and read the "report", I would be interested in an opinion on the cost of determining/disproving the diamondiferous/economic potential of a specific pipe, x270 which Read states is at least 15 hectares, perhaps 24? and is "true" kimberlite.
It appears overburden is significant, and kamafugite may have infiltrated or vise versa this very large kimberlite body.
Read recommends that further investigation is warranted since the Teck/CNB locaters of this pipe did not, in his opinion, do enough examination.
In my opinion a good weekend read that may provide insight into potential not only for CNB but also BSW,DGM,fipke (jv`s) and some others.
